Please repeat the "Generate Data" button and click each time on first "Get Image" Button.
If you don't see rubbish (in Y labels) and overlapped bars in image (like in this image), then we can be sure that the problem is in the Unigui/Sencha version. In this case I'd like to know if I can patch just this component, so I can not update my Unigui version by now.
I'm using Unigui 1.0.1424 (proffesional, registered to atorregrosa@tricom.es) and Delphi 10.3.

PD The Second "Get Image" button was for testing if I can get the image directly from object, but it only works in client side, not in server side (and I can't change the filename and destination folder).
Thx in advance
