[Bug] [ex Feature] Financial charts

Hello everyone.

I didn't know Apache also made graphs. Great news.

Only that looking through your examples online I can say that you should improve the financial graphs area.

In this regard I would like to show you how a very well made financial graph should be (apart from the mouse zoom that goes left and right which in my opinion is pathetic).

You should also allow the insertion of external data after the graph has already been formed.

Is it possible to obtain something similar in ECharts 6.0?

Thanks

I would also like to point out that if you scroll through the examples section on the site you will notice that it loads in a strange way leaving huge spaces between one section and another and it is almost impossible to select the desired example.

### What does the proposed API look like?

Obtain well done financial graphs where it is possible to insert data easily even after the graph has been created.
