Shaded Contour and Line Contour in one CONTOURF

Show older comments
I have a matrix A=m x n; X=m x 1; Y=n x 1; contourf(X,Y,A','linestyle','none')
I wish to superpose another matrix B (m*n) "in LINE CONTOUR" onto the previous
Please help...
It would be great if I knew to plot matrix B both in single color line with values written in between, or a contour with different color scheme....

I don't understand what you mean, what is a line contour? One without faces, like the normal contour?

Yea that's fairly easy. An example:
A=peaks(100);
B=peaks(75);
[~,h1]=contourf(A,'linestyle','none');hold on
[c,h2]=contour(B,'linecolor',[0 0 0])
set(h2,'ContourZLevel',10)
clabel(c,h2)
The second to last row makes sure that h2 is always drawn on top, although this case its not needed.

Happy to help.
The problem is that the colorbar changes the position-property of one axes when you place it outside of the plot area, as it is set to location='eastoutside' by default. There are several ways to solve this:
1) Align the position of the two axes at the end of the script. Add this at the end of the script:
cb=colorbar(ax1)
ax1pos=get(ax1,'position')
set(ax2,'position',ax1pos)
2) add colorbar inside the plot and then move it outside by changing its position. This prevents the axes position from being changed at all. Add this at the end of the script:
cb=colorbar(ax1,'location','west')
cb.Position=cb.Position+[0.6 0 0 0];
3) add colorbar normally, i.e. outside of plot, and change the position of the axes back again afterwards
ax1pos=get(ax1,'position')
cb=colorbar(ax1)
set(ax1,'position',ax1pos)
