ScottPlot VS Interactive Data Display for WPF

The pull request from which this code is based on: https://github.com/ScottPlot/ScottPlot/pull/2221

ScottPlot is another .NET option besides OxyPlot and LiveChartsv2. There are a few libs that wrap matplotlib from Python like MatplotlibCS if that's your thing. You could also WebView2 and d3.js for an offline app. It really depends on what you're producing charts for: a highly stylized figure might not be appropriate for an academic publication, interactivity may be important, a very specific type of chart out-of-the-box might be important, etc.

I know you said no 3rd party controls but https://scottplot.net/ is a free and open-source plotting library for .NET which you can use from WPF. The Github page is here https://github.com/ScottPlot/ScottPlot

I dont know what type of visualisations you need but if you are doing a simple WinForms app you cant beat ScottPlot

I was mostly wondering about the charting library itself, in isolation of QuestPDF. ScottPlot is the other one I was considering besides microcharts. Since you mentioned using QuestPDF in production for reporting, I was wondering if perhaps you also used any of the OSS charting libraries in building those reports and if you have any insights you can share. Docs and demos are a good start when picking one, but lived experience is very valuable.

A short story / cautionary tale of the last time I had to add a chart to an old application: I had a project that needed to make use of Microsoft's Interactive Data Display [formerly Dynamic Data Display or 'D3']. I don't recall what feature it was that was specifically being asked for, but D3 did it and was the only real option outside of springing for one of those massive/pricey component libraries. If you want to talk about how silly it is to create an entire separate process to wedge a WPF control into a WinForms app as a MDI child, that communicated via pipes, I've got notes. In short: the tech may be dated, but I always welcome more WinForms controls.
