Best charting library to work with Qt?

Piyush

Hi,

I am currently working with matplotlib for charts on my Qt application. However, it seems that matplotlib is not a good option for me as I require charts with rapid updates and interactive charts with zoom functionality. I also want to update charts where in I would be required to change (clear and re-draw) the axis repeatedly.

So, I am currently looking for some alternate charting libraries which are interactive, positive on frequent updates, for which I am considering options like Plotly, PyQtGraph and Bokeh. Alsthough, PyQtGraph seems responsive but Plotly seems more popular.

So could you please suggest which charting library is the best for use with Qt?? Matplotlib vs plotly vs PyQtGraph vs Bokeh?

2 most widely used chart libs in Qt world are:

Qt Charts module (it's built into official Qt releases)
Qwt

Have you tried QCustomPlot? I've found it pretty useful

Qwt is a best (but it does not support QML).
