How to make matplotlib charts fast update & alternative for matplotlib

[Piyush]

Hi,

I am currently working on a project which require quick updates of 4-5 charts on press of a button. I used matplotlib for the same. However, the Qt application gets really slow after one or two iteration of updating chart and ends up not responding.

Is there any other alternative for matplotlib for PyQt5 which is compatible with Python?

I searched a few of them, i.e., OpenGL, Plotly and PyQwt. Which one would you think is better in terms of fast updates which included redrawing axis and labels apart from the plot lines themselves.

Hi
I would try Qwt. It was pretty fast for me.
