I have some values of stretch that I need to assign to a given set of elements and then I want to show a contour plot of those values on the geometry that I get by plotting the elements through the nodes. How can I do?

Hi Federica,
I understand that you have n-values for both stretch and corresponding centroids and wish to create a contour plot for the available data.
Following steps might be useful to achieve the required plot:
- Create a grid that covers the range of the centroid coordinates:
[X, Y] = meshgrid(centroid(x),centroid(y));
2. Create the Contour Plot using “contour” function:
contour(X, Y, corresponding values);
Here is an example code for plotting contour plot:
centroid = [linspace(-2*pi,2*pi); linspace(0,4*pi)]';
[X1,Y1] = meshgrid(centroid(:,1),centroid(:,2));
stretch = sin(X1)+ cos(Y1);
contour(X1,Y1,stretch)
For more information related to contour plot please refer the shared MATLAB documentation link: https://www.mathworks.com/help/matlab/ref/contour.html
Hope this helps.
