Re: Script BOY IntensityGraph to show areaDetector output of variable size

[Phil Atkin <phil.atkin@pixelanalytics.co.uk>]

Thanks Gabriela,

- but I guess my question was ambiguous.  If I understand correctly, 
your script adjusts the height of the IntensityGraph widget so that its 
aspect ratio matches the image.

But the IntensityGraph will not display anything at all unless I set its 
Data Height and Data Width properties to match the attached array.  Do 
you have something to accomplish this?

Also: I have no idea how to actually attach the code or make it run at 
an appropriate time.  Can you point me at documentation that describes this?

Thanks

Phil
