0.2.x roadmap

[dandelany]

Work has begun on v0.2.0 and will be tracked in the 0.2.x branch. Main objectives are:

• Improved label layout features and speed due to better pre-emptive label measuring.
• More modularization of component structure - export parts of charts, not just entire charts, so the parts can be composed individually.
• Encapsulation of reusable and extractable Component features using higher-order components. Not just for DRY-ness, but to make the Components themselves as simple as possible.

The feature roadmap will be tracked in this checklist, which we'll add to and edit as we go along:

• Refactor mouse events on new XYPlot component
• Production build of examples sandbox, for performance testing
• Port existing charts to new XYPlot format (see below)
• Bar component
• RangeRect component
• Use class-type components instead of createClass
• resolveXYScales HOC to resolve scale prop from domain/range/data/size/etc.
• resolveObjectProps HOC to handle setting default props for {x,y} and {top, bottom, left, right} shaped props
• Use measure-text to pre-measure labels
• XAxis and YAxis components
• Unit test which renders the examples
• Update lodash to 4.5.x
• Add babel plugin for ESNext class properties
• Axis label placement - see AUDINP-232

API changes

• All XYPlot axis-related props should now be passed as props to <XAxis /> and <YAxis />, which must be included as children of XYPlot for axes to be rendered.
• axisType --> scaleType
  • Now there is "scaleType" vs "dataType", both have changed a bit
• invertAxis --> invertScale
• getValue --> getX / getY
• scaleWidth/scaleHeight --> width/height in sub-xyplot-charts?
• AreaHeatmap --> RectAreaHeatmap

Progress porting existing charts to 0.2.x/XYPlot2

• AreaHeatmap
• BarChart
  • RangeBarChart
  • AreaBarChart
• Histogram
• KernelDensityEstimation
• LineChart
• MarkerLineChart
• ScatterPlot

Future plans (out of scope for 0.2.x)

• Resolve questions about plotWidth vs. scaleWidth vs. width (& height) in XYPlot charts
• Pre-defined common interactions for eg. scrubbing, zooming, tooltips.
• PureRender/shouldComponentUpdate for all chart/axis components
• Automatically determine axis tickCount (and therefore # of axis labels) by bumping down the # of ticks until all of the labels fit
• Rotated axis value labels (90 degrees or arbitrary rotation? how to handle collision detection?)
• Y Axis value label vertical & horizontal alignment
• position: 'zero' option for X/Y Axis and subcomponents - place the axis on the scale's zero line, wherever it falls.
• extraMargin/minMargin props?
• Key attributes for scatterplot points
• Axis label alignment - see AUDINP-233
• MarkerLine component
• LineSeries vs LineChart component
• Use d3 path generator + interpolation for LineChart
• Unit tests for all chart types
• auto-determine different class names for chart series?

This is old - 0.2.0 and 0.3.0 have been released. Will open new tickets for remaining outstanding issues for future releases.
