Origin Ver. 2021b and Service Release (Select Help-->About Origin): 9.8.5.204
Operating System: Windows 10 21H1

MATLAB Com server script given in origin scripting examples is throwing error, when used with latest version of Origin 2021b. Below is the line where the error (Type mismatch) occurs:

Error: Type mismatch, argument 3
Error in MATLABCallOrigin (line 81)
dps.Add(dr, 202); % 202 for symbol+line plot

I didn't face such a situation with the previous versions of Origin. Would appreciate your help if anybody let me know how can I pass the argument to Origin without any Type mismatch or any quick fixes to avoid error.

Hi mahesh2444,

Sorry for the inconvenience.

Would you mind to try to add "true" as the 3rd argument to see the problem would be gone?

i.e.
dps.Add(dr, 202, true);


We will try to fix the problem accordingly. (bug record id: ORG-23784)

We added the 3rd argument in 2021b.
It is used to indicate whether the data range dr is a composite range or not.

XYRange/XYZRange is composite range, so in the sample case it should be true.

In 2021b we mistakenly treat it as not-composite, so you will have to pass it explicitly to workaround the problem.
