Origin Ver. and Service Release (Select Help-->About Origin): 9.0.0 b45 (academic)
Operating System: Win 7, 64bit
I am plotting a color fill contour map as attached. However, an area above the data area also gets filled. All black dots represent data points. I have tried to use boundary X&Y but it does not help. If I delete the right-most data point, it will be redrawn from a new right-most data point. Any suggestion for how I can I fix this issue?
Thanks,
Thee

The current Contour Color Fill does not support concave edges.
You can use the boundary X,Y option but you have to have the right data.
First, hide all the Contour lines, disable color fill and turn off Show Grid Lines so you just have Show Data Points.
Then run this script:
// BEGIN SCRIPT
dotool 3;
def pointproc {
ty $(x)\t$(y);
}
// END SCRIPT
Working either clockwise or counterclockwise, double-click on each point of the proper data boundary. In your case, the boundary is a crescent.
When finished, press Esc or click the Pointer Tool.
Copy and paste the data that was output to 2 new columns in the source XYZ data sheet.
Set those columns as your X and Y data boundary values on the Contouring Info page.
Re-enable color fill and contour lines. Hide Grid Lines and Grid Points if you wish.

| Thank you Greg for your help. I have followed your instruction; however, the results are still the same as you mentioned about the limitation of this version. I will have to dissect the plot into several portions in order to avoid the concave edge. Hopefully it will work. Thank you again for your suggestion and advice. |
