36 <li>In the filter box, type
<code>point
</code>.
</li>
37 <li>In the
<em>drawPoints
</em> text box, enter
<code>true
</code></li>
38 <li>Press
<code>enter
</code> or click
<em>Refresh
</em>. You will
39 see dots on the graph where points exist.
</li>
40 <li>In the
<em>pointSize
</em> text box, enter
<code>5</code></li>
41 <li>Press
<code>enter
</code> or click
<em>Refresh
</em>. The dots
43 <li>Type
<code>callback
</code> in the filter box.
</li>
44 <li>Instead of a text box, you will see buttons that can be used
45 to define callbacks. Click the button for
<em>clickCallback
</em>.
</li>
46 <li>You will see that the prototype function body is
47 <code>function(e, x, points){ }
</code>. Paste in this
48 replacement function:
<p/>
49 <code>function(e, x){ var elem =
50 document.getElementById(
"messages"); elem.innerHTML =
51 elem.innerHTML + x +
"<br>"; }
</code></li>
52 <li>Click the
<em>OK
</em> button. The
<em>clickCallback
</em>
53 button now says
<code>defined
</code> instead of
<code>not defined
</code>.
</li>
54 <li>Click anywhere on the graph. The x-value will appear on the
56 <li>If you click directly on a point, then an alert box will
57 indicate that you've clicked on a point. That's because the
58 <em>pointClickCallback
</em> was defined already.
</li>
59 <li><b>Have fun and send feedback!
</b></li>
62 The palette on the right contains (most) Dygraphs options. Here's
65 <li>The selection box on top can be used to choose your own data source.
</li>
66 <li>Use the filter box to constrain your selection. For instance,
67 typing
<code>draw
</code> will show all options with that phrase in
69 <li>Each field has specific types. The types are not documented,
70 but if you hover over an entry (or click on it) it will give you a
72 <li>Enter a new value for the option, and hit the
73 <code>enter
</code> key, or the
<em>Refresh
</em> button.
</li>
74 <li>Some types require special consideration:
75 <li>integers, floats, strings and booleans can be entered
77 <li>arrays of elements can be comma-separated
<em>except string
78 arrays, which are (at the moment) semicolon-separated (anyone
79 interested in making a good string array parser, take a shot.
</em></li>
80 <li>Callbacks are defined in a (crappy tiny) dialog box. If the
81 function isn't defined, then a prototype of the function will be
82 presented to the user.
</li>
86 Then in the filter text box, type
"point". Set drawPoints: true and
