Re: Plotting images in Phoebus

["Kasemir, Kay via Tech-talk" <tech-talk@aps.anl.gov>]

The axis min/max is independent from the image size.

You can enter any numbers for the X or Y axis range, like 0 .. 100 or 100 .. 0 or -50 .. 50  or 50 .. -50.

"Minumum" doesn't have to be less than "maximum".

Subject: [EXTERNAL] Plotting images in Phoebus

 

Hi

 

I would like to display images using Phoebus. If I use the image widget it shows axes starting from 0 in the bottom left, however it displays the image with the origin in the top left, as is convention https://matplotlib.org/stable/tutorials/intermediate/imshow_extent.html

 

Is it possible to configure which way round the axes of the image (and other plot) widgets are displayed?

 

Thanks,

 

Will
