Origin Ver. 9.1.0 64 bit SR1
Operating System: Windows 7 64 bit
I am exporting a matrix of Z values from LabVIEW to Origin which I later want to plot in Origin as an intensity map.
I want to save the X and Y axis range information while I am doing that, but I haven't been able to figure out how so far.
I am referring to the equivalent of these actions within Origin:
- Select all rows and columns
- right-click menu: Set Matrix Dimension/Labels...
- fill in the 4 values X1, X2, Y1, Y2 in the "xy Mapping" tab:
Map Column to x: From X1 To X2
Map Row to y: From Y1 To Y2
I suspect that using a labTalk script (from within LabVIEW) might do the trick, but my attempt to execute the following script on the Matrix Object I just created and populated in LabVIEW, doesn't do anything (it doesn't throw an error either):
mdim cols:=%d rows:=%d x1:=%f x2:=%f y1:=%f y2:=%f;
where the %d and %f values are replaced by the correct values after passing through a Format to String function.
Any suggestion would be welcome. |

I have made some little change to the one of Origin's built-in examples, "Matrix Access.vi", and get it correct. When open this vi in LabVIEW, I changed the LabTalkStr as the following:
mdim x1:=10 x2:=20 y1:=100 y2:=200;
matrix -v sin(x)+cos(y);
To see if the XY data is set correct, you can turn on XY data by menu View: Show X/Y.

Where would I find the Matrix Access.vi? Or equivalently, what sequence of calls to the Automation Server is performed?
Nevermind, I found it: http://www.originlab.com/doc/LabVIEW/examples/Matrix-Access
However, if I try that idea, it doesn't work for me. Here is the code I use:
When I execute it, no error is generated, the matrix is populated as instructed but the X and Y values shown when performing the View>>Show X/Y trick are the default values 10/i (where i = 1 to N, where N is the dimension, are the value indices). In other words, the default value of 10 for the X and Y range are not modified by the script. |
