Origin Ver.8 and Service Release sr4
Operating System:WinXP
Hi everyone,
I have several XYZ contour maps all with the same XY grid. I would like to cut out individual areas from the counter maps but the area should be the same among the different counter maps. Is it possible to select an area with the zoom tool and then cut out the visible data from the whole data set? I have tried the mask tool but it seems not to work on contour maps.
second:
Is it possible to overlay different colored contour maps and get a different color gradings in consequence of overlapping colors?
Thanks a lot,
|

Hi,
Regarding your second question, the upcoming 8.5 version will support color transparency so with two plots in a layer, transparency can be set to see thru to the other data.
See what is new in 8.5 here:

Regarding first question, I think this will need some custom code to get the data from the raw dataset. Is the area of interest a rectangle or some arbitrary shape?

Hi,
This could be scripted using LabTalk. You could write script to get the coordinates of say a rectangle placed on the contour, and then go to the source/raw data and extract all raw XYZ points that fall inside that rectangle?
You could look at our scripting guide to begin with:
http://wiki.originlab.com/~originla/wiki/index.php?title=Category:LabTalk_Programming
Note that starting with 8.1, the XYZ contour plot also supports custom boundary so you can simply turn off plotting outside of a custom boundary, and thus effectively display only the contour inside your desired rectangle, that may work in your case?
