Hi all,
I want to plot two y-axis data on the same x-axis. The problem is that the first plot should be done using command 'pcolor' and second one using normal 'plot' command.

basically this is what I want to do

command for first plot is

pcolor(x,y1,z);colorbar;


command for second plot is

plot(x,y2)

Here x is x-axis data,y1 and y2 are two different data's against x-axis data.

I want it to happen on the same plot.

The inbuilt matlab command 'plotyy' doesn't help as it uses 'plot' command for both plots. I also tried the matlab help about 'Multiple Axes on Same figure'. But then what happens , the x-axis data which is same for both axes has different scalings on both cases

Double-check the documentation for PLOTYY -- what do the fifth and sixth
input arguments do?

Thanx for the reply, I checked the documentation for 'plotyy', but it specifies that the functions that can be used are of the form function(x,y). But I want to use 'pcolor' which accepts three arguments.

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

then pass mypcolor as the function

Hello Sir,
Sorry for the late reply, I tried the solution you specified recently. I defined the variables as you mentioned. But it results in a error.

??? Error: "mypcolor" was previously used as a variable,
conflicting with its use here as the name of a function or command.
See MATLAB Programming, "How MATLAB Recognizes Function Calls That Use Command Syntax" for details.
