Hello everybody! beginner here... ;) I'm writing a little GUI in PYQT5 to display images and I'd like to add this histogram function. The problem arises when my images are almost or completely black. In case of an image with all 0 pixels the histogram breaks my application raising the following error:
File "C:\Program > Files\Python36\lib\site-packages\pyqtgraph\graphicsItems\ImageItem.py", > line 464, in getHistogram > bins = np.arange(mn, mx+1.01*step, step, dtype=np.int) > ValueError: arange: cannot compute length In case of an image with very few counts the histogram breaks my application raising the following error: File "C:\Program > Files\Python36\lib\site-packages\numpy\lib\function_base.py", line 727, in > histogram > '`bins` must increase monotonically, when an array') > ValueError: `bins` must increase monotonically, when an array Any idea for any solutions? I don't have the knowledge, unfortunately, to modify the widget myself. Thanks! Luca ps... I will prepare a minimal example in few hours, but I preferred to post this first -- You received this message because you are subscribed to the Google Groups "pyqtgraph" group.
