Hi,

I'm new to QT and using the Windows desktop version. I'm able to use Qt Creator and Python to display the QtTableWidget with data plus use matplotlib to display a line graph in a separate window. What I want is to display line graph within the table cells, like this website

How on Earth would I do that? Thanks for your help.

Hi,

What about rendering that graph in an image and just show the image in your cell ?

Thanks, I got it working by using matplotlib to plot to canvas. Then converting this to a an rgb uint8 numpy array. Then converted to QImage that I could send to either a background brush or a QIcon to set a QTableWidgetItem to set to the QtTableWidget.
