how to set the negative values on a diagram to zero

hello all,

could you kindly advise me how to set a limit on a diagram.

As you may see on the diagram that i have plotted, the orange graph tends to show negative value.

I wish to set a limit on the y-axis to zero, so that there are no more negative value appearing on the diagram.

One approach:

figure
plot( ... )
ylim([0, max(ylim)])

if you only want to limit the y-axis range.
