I am looking for a robust application to analyze plots that typically have a primary y-axis with bars (or stacked bars) and a secondary y-axis with scatter points.

Here are some examples of common plots. The application should be robust enough to capture data from a high variability of similar plots automatically and accurately.

plot_1

plot_2

Does anyone know of an application or method that performs well for this task?

I tried using Google Deplot a Visual Question Answering model, but the performance was very poor. Additionally, I had difficulty converting the output to a pandas DataFrame efficiently.
