Re: How can I apply some transformation to the X/Y axis coordinates of CSS Intensity Graph widget?

When you use the latest version of CS-Studio, https://github.com/ControlSystemStudio/phoebus (https://controlssoftware.sns.ornl.gov/css_phoebus/), you can simply enter whatever axis range you want for images. It defaults to the pixel size, i.e. 0 .. (width-1), but you may also directly enter -8.2852 and 6.8376 as the horizontal axis minimum and maximum.

(Note that the "Intensity Graph" widget has been renamed into "Image Widget", but it'll map that automatically when you open existing *.opi files)

Subject: [EXTERNAL] How can I apply some transformation to the X/Y axis coordinates of CSS Intensity Graph widget?

 

Hi, 

I use CSS Intensity Graph to show the 2D   image data from areaDetector module. 

https://www.dropbox.com/s/du09abigpjebybw/css_intensity_graph.png?dl=0

The coordinates of    X axis and Y axis  are from 0 to 491.

How can I apply some kind of transformation to the coordiate?

For example, Xnew = (X - 250) * 0.05,

the values of   Xnew will be from -8.2852 to 6.8376.

ps I have     few experience on areaDetector module.

Best regards.
