I am using the following code and have tried many variants in the hopes of getting the app to own it.
[X,Y] = meshgrid(xlin,ylin);
Z = griddata(x,y,z,X,Y,'cubic');
axis tight;hold on
When run in a matlab "program" it pops a detached window up that has the figure I want.
I want the image to be within the app (Axis?) generated with app designer. I am running R2020a.
