Utkarsh, I've updated that page (http://mypage.iu.edu/~heiland/pv-stuff/) with my latest playing around. Basically, I discovered the "Plot Over Line" filter which does sort of what I want - ability to plot a row in an ImageData. However, I have a few questions:
1) why doesn't the plot dynamically update as I move (or as I move and then release the picked line source)? It almost seems to update at random. Does this have something to do with my PV Settings? I do have "Auto Accept" on. 2) is there some way to constrain the line source to take on only integer Y values? Basically, I only want to plot the exact values within the ImageData, no interpolation. 3) Instead of the Plot Over Line, I tried to use a VOI filter on the ImageData, thinking I might be able to extract just the row I wanted to plot, but saw that I am not allowed to specify a 1-D VOI. thanks, Randy On Oct 27, 2010, at 2:02 PM, Utkarsh Ayachit wrote: > So what are you plotting in the plot view?
