Recreate the standard split step line chart from dimple.js with rCharts. For a slightly more advanced example with steps, see this grouped horizontal 100% step area chart.
Note, as of now, will need to use the dimple v2.0.0 branch of rCharts.
install_github("timelyportfolio/rCharts@dimple_v2.0.0")Interpolation options are not limited to step. See the full set of d3.js interpolate options.
