“Responsive” chart or map will modify it’s features dynamically (even as you resize the container) based on the available area. For example: a full fledged line chart with legend guides, labels, titles and other elements will be displayed in all its glory if container is big enough.
If the container shrinks (i.e. you resize a browser window or view it on an iPad), it starts “compacting” the chart. First the legend is removed. Shrink it even further, axis titles are removed and its value labels are moved inside the plot area. Going even smaller, bullets, labels gone. All the way to the sparkline representation of the chart.
Plugin brings a universal set of pre-defined rules that you can use to instantly enable responsiveness. Those are custom-tailored for each chart/map type and will probably fit your requirements out-of the-box. All you need to do is to enable “responsive” plugin for your chart instance.
You can modify those defaults rules, or make your own list. The plugin allows that. (see further down this file for instructions)
