Create charts with uibuilder and Vue-ECharts
The original for this is kept on the uibuilder WIKI, note that the WIKI version may get updated from time-to-time, please check there for the latest version.
Here is a very simple example of producing a bar chart using Vue-ECharts which integrates ECHARTS with VueJS along with uibuilder v2, VueJS and bootstrap-vue.
Add an instance of uibuilder to your flows and replace the index.html and index.js files with the code below.
I'm loading the chart libraries using a CDN here, the next step would be to install the two packages using uibuilder's npm interface.
The example flow sends a random number to the app every 10 seconds which is used to update the chart.
Note that the following flow also includes 2 comment nodes containing the html and javascript.
