remove empty column at the beginning of pcolor

I made a pcolor plot from a 2D matrix. It seems pcolor generates an empty column at the beginning of the plot. Any suggestion how I can remove it? The last row is also missing in the plot.

I check the data that I plotted and it doesn't have a zero column at the beginning.

Can you share the matrix? or Code?

Answer 1

[Ameer Hamza]

It seems that your first column has NaN values. You can skip the first column in the call to pcolor()

M; % matrix used as input to pcolot
pcolor(M(:,2:end))

[Zahra Sheikhbahaee]

There are no NaN values in the first column. i just posted the data partially.

[Ameer Hamza]

You are starting xlim from 0. pcolor() starts from 1. Change the line to

xlim([1,T2+0.01]);
