1 | Axis-related properties: |
| 2 | includeZero | |
| 3 | valueRange | |
| 4 | labelsKMB | |
| 5 | labelsKMG2 | |
| 6 | pixelsPerYLabel | |
| 7 | yAxisLabelWidth | |
| 8 | axisLabelFontSize | |
| 9 | axisTickSize | |
| 10 | ||
| 11 | How is the y-axis determined? | |
| 12 | ||
| 13 | Dygraph.numericTicks: min, max -> set of ticks for axis | |
| 14 | tick = { label: label, v: value } | |
| 15 | ||
| 16 | addYTicks_: min, max -> void | |
| 17 | sets the yAxis and yTicks properties of layout_ | |
| 18 | ||
| 19 | drawGraph_: | |
| 20 | if set, uses this.valueRange_ ([low, high] array) | |
| 21 | -> adds ticks via addYTicks_ | |
| 22 | -> sets displayedYRange_ | |
| 23 | ||
| 24 | otherwise, calculates a good axis based on minY and maxY. | |
| 25 | ||
| 26 | this.displayedYRange_ is returned by the yAxisRange function. | |
| 27 | this is, in turn, used by the toDataCoords and toDomCoords methods. | |
| 28 | ||
| 29 | Path of least resistance: | |
| 30 | - in drawGraph_, calculate [minY, maxY] per-series | |
| 31 | - write a function to compute y-axes for all series, ensure only two axes. | |
| 32 | - make yAxis, yTicks into arrays in layout_ | |
| 33 | - add a series -> axis mapping to layout_, dygraph | |
| 34 | - add code to Renderer to add second axis. | |
| 35 | - add optional 'series' parameter to toDomCoords/toDataCoords | |
| 36 | ||
| 37 | This won't be compatible with stacked charts. |
