Manage data sets and display them as charts in WordPress.

Description

Allows you to manage data sets via a spreadsheet interface and present that data in chart form via the Chart.js or Highcharts chart libraries. The charts can then be embedded into a regular post via a handy shortcode.

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 M Chart Highcharts Library plugin before installing this update.

For full documentation please see the Wiki.
