streamgraph
streamgraph is an htmlwidget for making, well, streamgraphs.
A streamgraph (or “stream graph”) is a type of stacked area graph which is displaced around a central axis, resulting in a flowing, organic shape. Streamgraphs were developed by Lee Byron and popularized by their use in a February 2008 New York Times article on movie box office revenues. (Wikipedia)
The x axis values can be continous or dates.
TODO
- Support is planned for
xtsobjects, but not for a bit. - Support for categorical/discrete x axis
The following functions are implemented:
streamgraph: Create a new streamgraphsg_axis_x: Modify streamgraph x axis formattingsg_axis_y: Modify streamgraph y axis formattingsg_colors: Modify streamgraph axis text, legend popup label text and tooltip text colors (NOTE: no longer modifies fill colors, usesg_fill_*for fill colors)sg_legend: Add select menu “legend” to interactive streamgraphs
sg_fill_brewer: Specify a ColorBrewer palette to use for the stream fillssg_fill_manual: Specify a manual color palette to use for the stream fillssg_fill_tableau: Specify a Tableau color palette to use for the stream fllssg_add_marker: Annotate streamgraph with vertical line and labelsg_annotate: Annotate streamgraph with a label

0.5.1released -sg_colorsnow has nothing to do with the stream fills but does set the axis text, legend popup label text and tooltip text. - Version
0.5released - deprecated use ofsg_colors. Its functionality will change soon and is replaced by threesg_fill_*functions (brewer,manualandtableau) which makes more sense, is aligned to theggplot2way of specifying fill aesthetics and now makes it easier to highly customize the streamgraph appearance. - Versioin
