dynamically add more icone controller to Legend Controls

[majid1605]

Description

Hi In order to have more control over the chart and make changes on t he chart dynamically, I suggest adding a possibility to add different icons to the legend. Something like Trading View. By owning any event, people can implement whatever they want

Suggested solution

It is better for each overlays to have settings for this. For example:

overlays: [
      {
        name: "name",
        type: "Candles",
        main: true,
        settings: {},
        props: {},
        legendSettings: [
          {
            event: "handler1",
            icon: "myIcon1",
            tooltip: "tools1",
          },
          {
            event: "handler2",
            icon: "myIcon2",
            tooltip: "tools2",
          },
        ],
      },
    ]
