[Feature] Disconnect Toolbox from echarts.connect

[Maxdeboer9]

What problem does this feature solve?

Right now I have connected a few of my charts using echarts.connect (docs)

However, it also connects the toolbox from all the charts, so when using the magicType or saveAsImage feature, it will do these actions on all the connected charts. This will generate images of all the plots, instead of only the plot in question.

toolbox: {
    show: true,
    orient: 'vertical',
    left: 'right',
    top: 'center',
    feature: {
      mark: { show: true },
      dataView: { show: true, readOnly: false },
      magicType: { show: true, type: ['line', 'bar', 'stack'] },
      restore: { show: true },
      saveAsImage: { show: true }
    }
  },

The dataView does only display the data for the correct plot.

What does the proposed API look like?

An solution would be to have an extra parameter in toolbox like this:

toolbox: {
    show: true,
    orient: 'vertical',
    left: 'right',
    top: 'center',
    feature: {
      mark: { show: true },
      dataView: { show: true, readOnly: false },
      magicType: { show: true, type: ['line', 'bar', 'stack'] },
      restore: { show: true },
      saveAsImage: { show: true }
    },
    connect: false
  },

Where connect would default to false

Instead of the standard saveAsImage one could build a custom toolbox feature save tool for each chart - Demo.
Feature dataView can be also customized - Demo.
