Introduction

The EChart Menu plugin is a new easy-to-use charting userview menu plugin for Joget DX, and can be considered as an alternative to the default bundled Chart Menu. 

Just select any datalist in your app to display its records in several available graph types.
The additional benefits of using this plugin is the ability to reuse the datasource configuration & datalist filters in the selected datalist.

Also as a tip, you can also display multiple of these charts in a single page of a userview via Dashboard Menu.

Download this plugin from the Joget Marketplace here.

The JS library used: https://echarts.apache.org

For example, if a bar chart type is selected, to display the categories as a stacked bar chart, you can key in as such:

{
    stack : 'one',
	label: {
        show: true,
        precision: 1,

Examples as below:

{"type" : "line"}
{"type" : "pie",
 "radius" : "40%",
 "center": ["50%", "25%"],
