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

this is the very simple python script that I use:
from org.csstudio.opibuilder.scriptUtil import PVUtil
imageWidget = display.getWidget('Image')
imageXSizeWidget = display.getWidget('X-Size')
imageYSizeWidget = display.getWidget('Y-Size')
try :
imageXSizePV = imageXSizeWidget.getPV()
imageYSizePV = imageYSizeWidget.getPV()
nImageRows = PVUtil.getLong(imageYSizePV)
nImageColumns = PVUtil.getLong(imageXSizePV)
imageWidget.setPropertyValue('graph_area_width', 512)
imageWidget.setPropertyValue('graph_area_height', (512.0/nImageColumns)*nImageRows)
except :
pass

Hi,
I'm using BOY IntensityGraph to show a (stdArray) output image from an areaDetector driver/plugin.
The size of my array changes quite a bit.
Can someone tell me (in laborious detail if necessary, please) how to set up scripts or "embedded rules" on the IntensityGraph to cope with a variable-sized image?
Thanks!
Phil
