[Feature] Improvements to the way tooltips are displayed

Description

In the process of analyzing the collected questionnaires, one such reply attracted our attention: " Add interactive gadgets like zoom or frame selection of some nodes to the display diagram. "

The current display method is that when the mouse is moved over the icon of issues, the related line chart will be displayed.

• One way is to add markers so that the chart can be zoomed in or out. Just like the zoom in and out logo of the comment box on github:

• The other way is to add a button to the chart, similar to PloarDB, and a large picture will pop up after clicking it. And you can also add an "Export" button to facilitate users to export related charts.

Vote for the second one. It is easy to implement and we can add more operations in the separate window, like "Export" as mentiond.

My idea is also the second one, it seems more convenient.

Some simple operations like save, zoom, restore, etc., refer to echarts chart configuration, add the corresponding configuration.https://echarts.apache.org/v4/zh/option.html#toolbox.feature.dataZoom

I think that if the original format is to be retained, then adding an "export" button would enough, otherwise the display would be very crowded.

The above is an example from its documentation, and the buttons are configured according to their own choice.
