Feature Request: Graphing Debug Variables

Type: Feature Request

Something that would be super awesome for this extension would be to be able to plot debugging variables on a graph. I am not a UI guy, but I would think that with all the CSS and JS, this might be not as hard as it is to implement in other IDEs? I think an example is the best way to explain this.

1. Mark a variable(s) in the debug view window as graphed.
2. Internally, the extension knows to either use GDB trace or to add a breakpoint on modification.
3. The extension takes these values as the program runs and plots them as series on a graph.

Another option would be to allow the X axis to either be "time" or "sample". In cases of debugging tests, sample would be most useful. If you were debugging something real-time, time would probably be most useful.

The result would be something like this:

Eventually, expanding graphing capabilities would be a truly powerful tool for understanding a program's execution at a glance and IMO would greatly speed up debugging capabilities, giving VSCode and this plugin a real edge over other IDEs.

Thanks for reading and thanks for all the work on the extension!

The issue names no files, tests, or entry points. Start by reviewing the extension's debug-view and trace or breakpoint architecture; done would mean selecting variables for plotting and displaying their values as graph series against either time or sample.
