metricsgraphics is an 'htmlwidget' interface to the [MetricsGraphics.js](http://metricsgraphicsjs.org/) D3-based charting library.
Charts look best in a Boostrap page (unless you customize your own CSS).
You can see [core examples] (http://rpubs.com/hrbrmstr/53741) and [fairly extended grid example](http://rpubs.com/hrbrmstr/mjs_grid_07) on RPubs.
The following functions are implemented:
- `mjs_plot`: Create a new metricsgraphics.js plot
- `mjs_line`: metricsgraphics.js linechart "geom"
- `mjs_add_line`: used to add additional columns for a multi-line chart
- `mjs_hist`: Shortcut for plotting MetricsGraphics histograms
- `mjs_histogram`: Plot Histograms with MetrisGraphics
- `mjs_add_legend`: adds a legend to a line (or mult-line) chart
- `mjs_point`: metricsgraphics.js scatterplot "geom"
- `mjs_bar`: metricsgraphics.js bar chart "geom"
- `mjs_axis_x`: Configure x axis ticks & limits
- `mjs_axis_y`: Configure y axis ticks & limits
- `mjs_labs`: Configure axis labels & plot description
- `mjs_add_baseline`: Sets a baseline line/label
- `mjs_add_marker`: Sets a marker line/label
- `mjs_grid`: `grid.arrange`-like functionality for `metricsgraphics` charts
- `mjs_add_mouseover`: provides support for MetricsGraphics [custom rollovers](https://github.com/mozilla/metrics-graphics/wiki/Graphic#mouseover)
- `mjs_add_confidence_band`: provides support for confidence bands
- `mjs_annotate_region`: Region annotations for line charts [EXPERIMENTAL]
- `mjs_add_css_rule`: Add a CSS rule to the rendered htmlwidget
