Allows you to manage data sets via a spreadsheet interface and present that data in chart form via the Chart.js or <a href="https://github.com/methnen/m-chart-highcharts-library/" rel="nofollow ugc">Highcharts</a> chart libraries. The charts can then be embedded into a regular post via a handy shortcode.
Note: Starting with version 1.8 the Chart.js library is no longer on the 2.x.x branch which introduces some <a href="https://www.chartjs.org/docs/latest/getting-started/v3-migration.html" rel="nofollow ugc">breaking changes</a>. This will probably only affect you if you were modifying the default Chart.js behavior in some way.
Note: Starting with version 1.7 Highcharts is no longer included with this plugin by default. If you’d still like to use the features that require Higcharts please install the <a href="https://github.com/methnen/m-chart-highcharts-library/" rel="nofollow ugc">M Chart Highcharts Library</a> plugin before installing this update.
