Well, he had no way of knowing that you had previously used mypcolor as a variable. Did you try changing the name? For example:

pcolorwrapper = @(x,y) pcolor(x,y,MyC)

What about the "hold on"
Is it what you want?

%% Test
x = 1:5;
y1 = x*2;
y2 = x.^2/5+2;

pcolor(x,y1,x'*y1)
hold on
plot(x,y2,'r')

Hi thanx for the reply. I don't think using mypcolor earlier was the problem because i never used it before other than the line

mypcolor= @(x,y) pcolor(x,y,MyC)

My wild guess is Matlab is seeing this as a variable assignment rather than a function.

Hi, thanx for the reply. The problem is I want both the plot's y-axes overlapping, so if y1=1:5

and y2=-1:-1:-5 , if you plot using hold on, it comes on top portion and bottom portion of plot. I want them overlapped, using plotyy will do this, left y-axis will be 1:5 and same on right will be -1:-5. But plotyy (for me) is not working with pcolor.

'hold on' rulez? ;)


%% Test
x = 1:5;
y1 = x;
y2 = -x;

figure
pcolor(x,y1,x'*y1)
hold on
[AX,H1,H2] = plotyy(x,y1,x,y2)
set(H2,'LineStyle','none')
set(H1,'LineWidth',3)
set(H1,'Color','r')
