Dear Sir/Madam,

I'm writing to you about one possible bug I found using function "exchange X-Y axes" in Originlab.
The thing is that I have an image plot that I've obtained from the matrix using function "Image plot" (figure A on the attached screenshot). As yo can see the white spot has a Z value around 0.266 and coordinates KII around 0 and K(perpendicular) around 1.
Now I want rotate this plot so I press exchange X-Y axes button. Graph becomes rotated, but rotation is incorrect. As you can see (figure B on the attached screenshot) white spot has a Z value around 0.07 now and coordinates KII around 0.8 and K(perpendicular) around 0.37. The interesting thing that if I use data reader to read values in area with coordinates KII around 0 and K(perpendicular) around 1 I will get Z around 0.26-0.27, as it should be (figure C on the attached screenshot). SO I think there is a problem with displaying graph after exchanging axes. Of course value 0.07 should be darker that 0.28, but Origin displays it incorrectly for some reason.
I've tried pressing Crt-R , saving/loading file, changing the X and Y display range, but there was no effect.
I will very appreciate if you help me to solve this problem.

Hi,

Thanks for pointing out of this bug. Exchange XY tool cannot work properly in Image plot. We have submitted a JIRA for this and will fix it in the future version:

https://originlab.jira.com/browse/ORG-15552

Right now, please do not use Exchange XY tool in image plot. Instead, please transpose matrix first (use menu Matrix: Transpose), and then plot an image plot.

Thanks,
Amanda
