thank you for the feedback. I’m not sure if it’s possible to create a graph with such big width, but I understand the issue. Instead of a fixed 1200×750 resolution I can add a popup menu with some selectable presets. This is easy to implement, we have to test what is feasible.
It may also an option (for the future) to drop the image creation and use a js viewer for the data, where we can zoom in/out and scroll.
