+## dygraphs developer notes
+
+So you've made a change to dygraphs and would like to contribute it back to the open source project. Wonderful!
+
+This is a step-by-step guide explaining how to do it.
+
+### How-to
+
+To build dygraphs, run
+
+ gulp dist
+
+To run the tests, run:
+
+ gulp test
+
+To iterate on the code, open `tests/demo.html` (or one of the other demos) in your browser.
+
+To iterate on a unit test, change `it` to `it.only` in the Mocha test, change the browser from `PhantomJS` to `Chrome` (or whatever you like) in `auto_tests/karma.conf.js`, run
+
+ ./node_modules/karma/bin/karma start auto_tests/karma.conf.js
+
+and hit "DEBUG" in the Karma UI.
+
+### dygraphs style
+
+When making a change, please try to follow the style of the existing dygraphs code. This will make the review process go much more smoothly.
+
+A few salient points:
+
+1. We try to adhere to Google's [JS style guide][gstyle] and would appreciate it if you try to as well. This means:
+ * No tabs! Indent using two spaces.
+ * Use camelCase for variable and function names.
+ * Limit lines to 80 characters.
+1. If you've added a new feature, add a test for it (in the tests/ directory) or a gallery entry.
+1. If you've added an option, document it in `dygraph-options-reference.js`. You'll get lots of warnings if you don't.
+1. If you've fixed a bug or added a feature, add a unit test (in `auto_tests`) for it.
+
+Adding a unit test ensures that we won't inadvertently break your feature in the future. To do this, either add to an existing test in `auto_tests/tests` or create a new one.
+
+### Sending a Pull Request
+
+To make a change, you'll need to send a Pull Request. See GitHub's documentation [here][pr].

-Axis-related properties:
-includeZero
-valueRange
-labelsKMB
-labelsKMG2
-pixelsPerYLabel
-yAxisLabelWidth
-axisLabelFontSize
-axisTickSize
-
-How is the y-axis determined?
-
-Dygraph.numericTicks: min, max -> set of ticks for axis
-tick = { label: label, v: value }
-
-addYTicks_: min, max -> void
-sets the yAxis and yTicks properties of layout_
-
-drawGraph_:
-if set, uses this.valueRange_ ([low, high] array)
- -> adds ticks via addYTicks_
- -> sets displayedYRange_
-
-otherwise, calculates a good axis based on minY and maxY.
-
-this.displayedYRange_ is returned by the yAxisRange function.
-this is, in turn, used by the toDataCoords and toDomCoords methods.
-
-Path of least resistance:
-- in drawGraph_, calculate [minY, maxY] per-series
-- write a function to compute y-axes for all series, ensure only two axes.
-- make yAxis, yTicks into arrays in layout_
-- add a series -> axis mapping to layout_, dygraph
-- add code to Renderer to add second axis.
-- add optional 'series' parameter to toDomCoords/toDataCoords
-
-This won't be compatible with stacked charts.

[gallery](http://www.dygraphs.com/gallery).

-often not quite correct.

- * @fileoverview Adds support for dashed lines to the HTML5 canvas.
- *
- * Usage:
- * var ctx = canvas.getContext("2d");
- * ctx.installPattern([10, 5]) // draw 10 pixels, skip 5 pixels, repeat.
- * ctx.beginPath();
- * ctx.moveTo(100, 100); // start the first line segment.
- * ctx.lineTo(150, 200);
- * ctx.lineTo(200, 100);
- * ctx.moveTo(300, 150); // start a second, unconnected line
- * ctx.lineTo(400, 250);
- * ...
- * ctx.stroke(); // draw the dashed line.
- * ctx.uninstallPattern();
- *
- * This is designed to leave the canvas untouched when it's not used.
- * If you never install a pattern, or call uninstallPattern(), then the canvas
- * will be exactly as it would have if you'd never used this library. The only
- * difference from the standard canvas will be the "installPattern" method of
- * the drawing context.
- */
-
-/**
- * Change the stroking style of the canvas drawing context from a solid line to
- * a pattern (e.g. dashes, dash-dot-dash, etc.)
- *
- * Once you've installed the pattern, you can draw with it by using the
- * beginPath(), moveTo(), lineTo() and stroke() method calls. Note that some
- * more advanced methods (e.g. quadraticCurveTo() and bezierCurveTo()) are not
- * supported. See file overview for a working example.
- *
- * Side effects of calling this method include adding an "isPatternInstalled"
- * property and "uninstallPattern" method to this particular canvas context.
- * You must call uninstallPattern() before calling installPattern() again.
- *
- * @param {Array.<number>} pattern A description of the stroke pattern. Even
- * indices indicate a draw and odd indices indicate a gap (in pixels). The
- * array should have a even length as any odd lengthed array could be expressed
- * as a smaller even length array.

- * @fileoverview This file contains the managment of data handlers
- * @author David Eberlein (david.eberlein@ch.sauter-bc.com)
- *
- * The idea is to define a common, generic data format that works for all data
- * structures supported by dygraphs. To make this possible, the DataHandler
- * interface is introduced. This makes it possible, that dygraph itself can work
- * with the same logic for every data type independent of the actual format and
- * the DataHandler takes care of the data format specific jobs.
- * DataHandlers are implemented for all data types supported by Dygraphs and
- * return Dygraphs compliant formats.
- * By default the correct DataHandler is chosen based on the options set.
- * Optionally the user may use his own DataHandler (similar to the plugin
- * system).
- *
- *
- * The unified data format returend by each handler is defined as so:
- * series[n][point] = [x,y,(extras)]
- *
- * This format contains the common basis that is needed to draw a simple line
- * series extended by optional extras for more complex graphing types. It
- * contains a primitive x value as first array entry, a primitive y value as
- * second array entry and an optional extras object for additional data needed.
- *
- * x must always be a number.
- * y must always be a number, NaN of type number or null.
- * extras is optional and must be interpreted by the DataHandler. It may be of
- * any type.
- *
- * In practice this might look something like this:
- * default: [x, yVal]
- * errorBar / customBar: [x, yVal, [yTopVariance, yBottomVariance] ]

- * @fileoverview Description of this file.
- * @author danvk@google.com (Dan Vanderkam)
- *
- * A ticker is a function with the following interface:
- *
- * function(a, b, pixels, options_view, dygraph, forced_values);
- * -> [ { v: tick1_v, label: tick1_label[, label_v: label_v1] },
- * { v: tick2_v, label: tick2_label[, label_v: label_v2] },
- * ...
- * ]
- *
- * The returned value is called a "tick list".
- *
- * Arguments
- * ---------
- *
- * [a, b] is the range of the axis for which ticks are being generated. For a
- * numeric axis, these will simply be numbers. For a date axis, these will be
- * millis since epoch (convertable to Date objects using "new Date(a)" and "new
- * Date(b)").
- *
- * opts provides access to chart- and axis-specific options. It can be used to
- * access number/date formatting code/options, check for a log scale, etc.
- *
- * pixels is the length of the axis in pixels. opts('pixelsPerLabel') is the
- * minimum amount of space to be allotted to each label. For instance, if
- * pixels=400 and opts('pixelsPerLabel')=40 then the ticker should return
- * between zero and ten (400/40) ticks.
- *
- * dygraph is the Dygraph object for which an axis is being constructed.
- *
- * forced_values is used for secondary y-axes. The tick positions are typically
- * set by the primary y-axis, so the secondary y-axis has no choice in where to
- * put these. It simply has to generate labels for these data values.
- *
- * Tick lists
- * ----------
- * Typically a tick will have both a grid/tick line and a label at one end of
- * that line (at the bottom for an x-axis, at left or right for the y-axis).
- *
- * A tick may be missing one of these two components:
- * - If "label_v" is specified instead of "v", then there will be no tick or
- * gridline, just a label.
- * - Similarly, if "label" is not specified, then there will be a gridline
- * without a label.
- *
- * This flexibility is useful in a few situations:
- * - For log scales, some of the tick lines may be too close to all have labels.
- * - For date scales where years are being displayed, it is desirable to display
- * tick marks at the beginnings of years but labels (e.g. "2006") in the
- * middle of the years.

-<p>You specify options in the third parameter to the dygraphs constructor:</p>
-<pre>g = new Dygraph(div,
- data,
- {
- option1: value1,
- option2: value2,
- ...
- });
-</pre>
-
-<p>After you've created a Dygraph, you can change an option by calling the <code>updateOptions</code> method:</p>
-<pre>g.updateOptions({
- new_option1: value1,
- new_option2: value2
- });
-</pre>
-
-<p>Some options can be set on a per-axis and per-series basis. See the docs on <a href="per-axis.html">per-axis and per-series options</a> to learn how to do this. The options which may be set in this way are marked as such on this page.</p>
-
-<p>For options which are functions (e.g. callbacks and formatters), the value of <code>this</code> is set to the Dygraph object.</p>

-dygraphs plugins
-----------------
-
-A single dygraph is actually a collection of dygraphs plugins, each responsible
-for some portion of the chart: the plot area, the axes, the legend, the labels,
-etc.
-
-This forces the dygraphs code to be more modular and encourages better APIs.
-
-The "legend" plugin (plugins/legend.js) can be used as a template for new
-plugins.
-
-Here is a simplified version of it, with comments to explain the plugin
-lifecycle and APIs:
-
-----------------
-
-// (standard JavaScript library wrapper; prevents polluting global namespace)
-Dygraph.Plugins.Legend = (function() {
-
-// Plugin constructor. This is invoked once for every chart which uses the
-// plugin. You can't actually access the Dygraph object at this point, so the
-// initialization you do here shouldn't be chart-specific. (For that, use
-// the activate() method).
-var legend = function() {
- this.div_ = null;
-};
-
-// Plugins are expected to implement this method for debugging purposes.
-legend.toString = function() {
- return "Legend";
-};
-
-// This is called once the dygraph is ready. The chart data may not be
-// available yet, but the options specified in the constructor are.
-//
-// Proper tasks to do here include:
-// - Reading your own options
-// - DOM manipulation
-// - Registering event listeners
-//
-// "dygraph" is the Dygraph object for which this instance is being activated.
-// "registerer" allows you to register event listeners.
-legend.prototype.activate = function(dygraph, registerer) {
- // Create the legend div and attach it to the chart DOM.
- this.div_ = document.createElement("div");
- dygraph.graphDiv.appendChild(this.div_);
-
- // Add event listeners. These will be called whenever points are selected
- // (i.e. you hover over them) or deselected (i.e. you mouse away from the
- // chart). This is your only chance to register event listeners! Once this
- // method returns, the gig is up.
- registerer.addEventListener('select', legend.select);
- registerer.addEventListener('deselect', legend.deselect);
-};
-
-// The functions called by event listeners all take a single parameter, an
-// event object. This contains properties relevant to the particular event, but
-// you can always assume that it has:
-//
-// 1. A "dygraph" parameter which is a reference to the chart on which the
-// event took place.
-// 2. A "stopPropagation" method, which you can call to prevent the event from
-// being seen by any other plugins after you. This effectively cancels the
-// event.
-// 3. A "preventDefault" method, which prevents dygraphs from performing the
-// default action associated with this event.
-//
-legend.select = function(e) {
- // These are two of the properties specific to the "select" event object:
- var xValue = e.selectedX;
- var points = e.selectedPoints;
-
- var html = xValue + ':';
- for (var i = 0; i < points.length; i++) {
- var point = points[i];
- html += ' ' + point.name + ':' + point.yval;
- }
-
- // In an event listener, "this" refers to your plugin object.
- this.div_.innerHTML = html;
-};
-
-// This clears out the legend when the user mouses away from the chart.
-legend.deselect = function(e) {
- this.div_.innerHTML = '';
-};
-
-return legend;
-})();

-Plugin Events Reference:

-- predraw
-- clearChart
-- drawChart
-- select
-- deselect
-
-TODO(danvk): document all event properties for each event.
-
-
-Special methods:

+ * @fileoverview This file contains the managment of data handlers
+ * @author David Eberlein (david.eberlein@ch.sauter-bc.com)
+ *
+ * The idea is to define a common, generic data format that works for all data
+ * structures supported by dygraphs. To make this possible, the DataHandler
+ * interface is introduced. This makes it possible, that dygraph itself can work
+ * with the same logic for every data type independent of the actual format and
+ * the DataHandler takes care of the data format specific jobs.
+ * DataHandlers are implemented for all data types supported by Dygraphs and
+ * return Dygraphs compliant formats.
+ * By default the correct DataHandler is chosen based on the options set.
+ * Optionally the user may use his own DataHandler (similar to the plugin
+ * system).
+ *
+ *
+ * The unified data format returend by each handler is defined as so:
+ * series[n][point] = [x,y,(extras)]
+ *
+ * This format contains the common basis that is needed to draw a simple line
+ * series extended by optional extras for more complex graphing types. It
+ * contains a primitive x value as first array entry, a primitive y value as
+ * second array entry and an optional extras object for additional data needed.
+ *
+ * x must always be a number.
+ * y must always be a number, NaN of type number or null.
+ * extras is optional and must be interpreted by the DataHandler. It may be of
+ * any type.
+ *
+ * In practice this might look something like this:
+ * default: [x, yVal]
+ * errorBar / customBar: [x, yVal, [yTopVariance, yBottomVariance] ]

+/**
+ * @fileoverview Description of this file.
+ * @author danvk@google.com (Dan Vanderkam)
+ *
+ * A ticker is a function with the following interface:
+ *
+ * function(a, b, pixels, options_view, dygraph, forced_values);
+ * -> [ { v: tick1_v, label: tick1_label[, label_v: label_v1] },
+ * { v: tick2_v, label: tick2_label[, label_v: label_v2] },
+ * ...
+ * ]
+ *
+ * The returned value is called a "tick list".
+ *
+ * Arguments
+ * ---------
+ *
+ * [a, b] is the range of the axis for which ticks are being generated. For a
+ * numeric axis, these will simply be numbers. For a date axis, these will be
+ * millis since epoch (convertable to Date objects using "new Date(a)" and "new
+ * Date(b)").
+ *
+ * opts provides access to chart- and axis-specific options. It can be used to
+ * access number/date formatting code/options, check for a log scale, etc.
+ *
+ * pixels is the length of the axis in pixels. opts('pixelsPerLabel') is the
+ * minimum amount of space to be allotted to each label. For instance, if
+ * pixels=400 and opts('pixelsPerLabel')=40 then the ticker should return
+ * between zero and ten (400/40) ticks.
+ *
+ * dygraph is the Dygraph object for which an axis is being constructed.
+ *
+ * forced_values is used for secondary y-axes. The tick positions are typically
+ * set by the primary y-axis, so the secondary y-axis has no choice in where to
+ * put these. It simply has to generate labels for these data values.
+ *
+ * Tick lists
+ * ----------
+ * Typically a tick will have both a grid/tick line and a label at one end of
+ * that line (at the bottom for an x-axis, at left or right for the y-axis).
+ *
+ * A tick may be missing one of these two components:
+ * - If "label_v" is specified instead of "v", then there will be no tick or
+ * gridline, just a label.
+ * - Similarly, if "label" is not specified, then there will be a gridline
+ * without a label.
+ *
+ * This flexibility is useful in a few situations:
+ * - For log scales, some of the tick lines may be too close to all have labels.
+ * - For date scales where years are being displayed, it is desirable to display
+ * tick marks at the beginnings of years but labels (e.g. "2006") in the
+ * middle of the years.

+dygraphs plugins
+----------------
+
+A single dygraph is actually a collection of dygraphs plugins, each responsible
+for some portion of the chart: the plot area, the axes, the legend, the labels,
+etc.
+
+This forces the dygraphs code to be more modular and encourages better APIs.
+
+The "legend" plugin (plugins/legend.js) can be used as a template for new
+plugins.
+
+Here is a simplified version of it, with comments to explain the plugin
+lifecycle and APIs:
+
+----------------
+
+// (standard JavaScript library wrapper; prevents polluting global namespace)
+Dygraph.Plugins.Legend = (function() {
+
+// Plugin constructor. This is invoked once for every chart which uses the
+// plugin. You can't actually access the Dygraph object at this point, so the
+// initialization you do here shouldn't be chart-specific. (For that, use
+// the activate() method).
+var legend = function() {
+ this.div_ = null;
+};
+
+// Plugins are expected to implement this method for debugging purposes.
+legend.toString = function() {
+ return "Legend";
+};
+
+// This is called once the dygraph is ready. The chart data may not be
+// available yet, but the options specified in the constructor are.
+//
+// Proper tasks to do here include:
+// - Reading your own options
+// - DOM manipulation
+// - Registering event listeners
+//
+// "dygraph" is the Dygraph object for which this instance is being activated.
+// "registerer" allows you to register event listeners.
+legend.prototype.activate = function(dygraph, registerer) {
+ // Create the legend div and attach it to the chart DOM.
+ this.div_ = document.createElement("div");
+ dygraph.graphDiv.appendChild(this.div_);
+
+ // Add event listeners. These will be called whenever points are selected
+ // (i.e. you hover over them) or deselected (i.e. you mouse away from the
+ // chart). This is your only chance to register event listeners! Once this
+ // method returns, the gig is up.
+ registerer.addEventListener('select', legend.select);
+ registerer.addEventListener('deselect', legend.deselect);
+};
+
+// The functions called by event listeners all take a single parameter, an
+// event object. This contains properties relevant to the particular event, but
+// you can always assume that it has:
+//
+// 1. A "dygraph" parameter which is a reference to the chart on which the
+// event took place.
+// 2. A "stopPropagation" method, which you can call to prevent the event from
+// being seen by any other plugins after you. This effectively cancels the
+// event.
+// 3. A "preventDefault" method, which prevents dygraphs from performing the
+// default action associated with this event.
+//
+legend.select = function(e) {
+ // These are two of the properties specific to the "select" event object:
+ var xValue = e.selectedX;
+ var points = e.selectedPoints;
+
+ var html = xValue + ':';
+ for (var i = 0; i < points.length; i++) {
+ var point = points[i];
+ html += ' ' + point.name + ':' + point.yval;
+ }
+
+ // In an event listener, "this" refers to your plugin object.
+ this.div_.innerHTML = html;
+};
+
+// This clears out the legend when the user mouses away from the chart.
+legend.deselect = function(e) {
+ this.div_.innerHTML = '';
+};
+
+return legend;
+})();
