Add a function to get the selected points in Blazor

[EWChina999]

With jQuery, we can get the selected points by a click on the line charts . Then we can generate another charts with the data point the user clicks on.
Could you add this feature in Blazor?
I googled the whole internet , found one website of ECharts has one feature . http://blazor-echarts.5izhy.cn/line/index .
I checked #147 and also demo https://plotly-blazor.azurewebsites.net/ , I did not find the function of getting the selected points . Could you make a demo ?

Have not tested it yet but there is a property called "Selected" in the Chart, which IMHO gives back selected Traces.
