Hi all,

I'm new to pyqtgraph and am very impressed by its capabilities. I already inserted the ImageView inside a PyQt program I'm writing. I love the ImageView features (historgram and ROI capabilities) but when the user select a ROI, I want to display a different plot at the bottom.... so my question is : is it possible to customize such a feature ? Intercept the ROI region and plot my own data instead of the profile plot offered by ImageView?

thanks for your help

Jean

Hi,

I don't know if it is possible with ImageView, but it should be very easy to do by subclassing ImageView and overwritting the roiChanged method.

Thanks Vincent for your reply,

I pretty much exactly what you said. It took me a few hours to figure out how everything works (and I'm still learning) but this library is very impressive. I love it.

Glad it helped! Indeed, Luke did an amazing job with this library.
