This plugin from the developers of https://goodgantt.com/ - Gantt chart for Trello Custom Graph lets you build a line, bar, and cumulative graphs based on your design elements.
==How To Build A Graph==

Note: This plugin does not create coordinate axes to give maximum flexibility in plotting. You need to create coordinate axes yourself.
