Feature Request: Graphing Debug Variables #8770

Open hacantorcooke opened 2 years ago

hacantorcooke commented 2 years ago

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: https://visualgdb.com/documentation/livevars/

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!

Similar to https://github.com/microsoft/vscode-cpptools/issues/6152 ( https://code.visualstudio.com/docs/datascience/jupyter-notebooks ), although in that case the code itself has control over the graphing versus the debugger. Seems like the front end implementation would be similar though.

This should definitely be in another addon, could you try https://marketplace.visualstudio.com/items?itemName=darudesandstorm.debug-plotter
