Make plot to start at 0

How to make lines start at 0, when plotting a matrix using the plot function?

To be more precise, this is what I want to solve: enter image description here

I was also facing the same problem and I resolved it by changing the Y-scale to 'linear' from 'log'. On figure window navigate Edit-> Axes Properties... Then select Y-axis and change the Y-scale to 'linear'.

Maybe with "xlim" will be enought.

It this case you can just write:

xlim([0,32]);

In a more generic case you might need to use:

a1=min(x);
a2=max(x);

xlim([a1,a2])

See the help for the plot command: When using the plot command with a single argument, Matlab implicitly plots the argument versus its index, so plot([3,5,9]) is equivalent to plot([1,2,3], [3,5,9]). More in general, plot(y) corresponds to plot(1:length(y), y) for a vector and plot(M) corresponds to plot(1:size(M, 1), M) for a matrix.

To plot starting from zero, you should thus do plot(0:length(y) - 1, y) for vectors, or plot(0:size(M, 1) - 1, M) for matrices, as in your case.
