Hello everyone
I am trying to plot the data in five different matrices in the same graphic. Interestingly, the elements of these matrices are not equal to NaN just in the spatial domain where, each of them, should exists. In principle, if the matrix element (i,j) of one of these matrices is different from NaN, it would not be again non-NaN in the other data arrays at (i,j). The five different matrices can be found here.
I would like to make the NaN elements to be completely transparent. As you can see, I am attaching a colormap, "Colors.txt", which is not white at the middle. I do not know if that makes any difference.
I am plotting the system as follows:
p1=uimagesc(Space_a,Space_b,mz_Tetra_1_Data);
set(p1,’alphadata’,~isnan(mz_Tetra_1_Data));
hold on
p2=uimagesc(Space_a,Space_b,mz_Tetra_2_Data);
set(p2,’alphadata’,~isnan(mz_Tetra_2_Data));
p3=uimagesc(Space_a,Space_b,mz_Penta_1_Data);
set(p3,’alphadata’,~isnan(mz_Penta_1_Data));
p4=uimagesc(Space_a,Space_b,mz_Penta_2_Data);
set(p4,’alphadata’,~isnan(mz_Penta_2_Data));
p5=uimagesc(Space_a,Space_b,mz_Hexa_Data);
set(p5,’alphadata’,~isnan(mz_Hexa_Data));
colormap(Colors);
clim([-1 1]);
Is the code above correct for my purpose?Hello everyone
