Thanks to both of you.
Could one of you give me a pointer on how to create such a rule?
Thanks

Hi Phil,
We do the same as Bruno mentions.
Data Height (ArraySize1_RBV)
Data Width (ArraySize0_RBV)
where the PVs are from the StdArray plugin.
In addition you’ll also need to have additional rules for setting the X and Y axis Min and Max values. These rules use the PVs from the detector driver that knows about binning and ROI selection:
X Axis Min - (MinX_RBV)
Y Axis Min - (MinY_RBV)
X Axis Max (MinX_RBV + ArraySizeX_RBV)
Y Axis Max (MinY_RBV + ArraySizeY_RBV)
We also use a another rule that defines the maximum intensity (the Maximum property) based on a PV. Then we have a Scaled Slider widget to change the intensity.

Hi Phil,
You can create two rules, for the data_width and data_height properties, that look at the $(P)ArraySize0_RBV and $(P)ArraySize1_RBV PV's
HTH,

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
