Helper Actions

Currently there are two helper actions provided:

1. beforeSetup

This is called before echarts has been initialized.

beforeSetup(context, chart) {}

{{echarts-chart option=option beforeSetup=(action beforeSetup)}}

2. afterSetup

This is called after all chart options and data have been set, as well as after the chart has been created.

afterSetup(context, chart) {}

{{echarts-chart option=option afterSetup=(action afterSetup)}}
