I am trying to generate a contour plot in originpro. I was successful to make this plot in matlab by using 3 sets of matrices. The related explanation is provided here from matlab website.
Does anyone know how to do the same in originpro? Thank you
contourf(X,Y,Z), contourf(X,Y,Z,n), and contourf(X,Y,Z,v) draw filled contour plots of Z using X and Y to determine the x and y values.
If X and Y are matrices, then their sizes must equal the size of Z. Typically, you should set X and Y so that the columns are strictly increasing or strictly decreasing and the rows are uniform (or the rows are strictly increasing or strictly decreasing and the columns are uniform). |

Hi Vahid H,
I am sorry that we don’t support to create a contour plot directly from three different matrices(X, Y, Z) at present, but I have a workaround for what you want:
I suppose you have three matrices in the project, now you can
1. Convert three matrices to three worksheets respectively
(Select Matrix: Covert to Worksheet from Origin menu, and then select XYZ columns in Method item)
2. Put the Z columns of the three worksheets to a new worksheet together, and set as X column, Y column and Z column correspondingly.
(Select Worksheet: Copy Column to from Origin menu)
3. You have a new XYZ vector to create a contour plot now
I also have a piece of script for you. You can execute it in Script Window
//New 3 workbooks for converting matrices
loop(ii, 1, 3)
{
newbook name:= "WBook$(ii)" option:=lsname;
}
//New workbook for result
newbook name:= "Result" option:=lsname;
ii = 1;
//Loop over all matrix books in project
doc -e M
{
str$ = "WBook" + "$(ii)";
m2w method:=xyz ow:=[%(str$)]Sheet1!;
colcopy irng:=[%(str$)]Sheet1!Col(3) orng:=[Result]Sheet1!Col($(ii));
ii++;
}
Hope it helps.

Yuki

Thank you, Yuki. In the content of the link that you sent me contour plot based on three vectors are mentioned. Please correct me if I am mistaken. I am interested in the contour plot of three different matrices(X, Y, Z).
