Range selection in matlab plots

hello all,

I need some help with plotting. I have am plotting a set of data points as shown in figure. There are no 0 value data points in the set that I am plotting, but I want to have zero point on the plot. I want the x and y axis scales starting from 0. I am looking forward to hear from you guys.

Thanks.

Change the lower ylim limit to zero:

x = 0:19;
y = randi([5 9], 1, 20);

figure
plot(x, y, 'p')
ylim([0 max(ylim)])                     % Change The Lower ‘ylim’ Limit To Zero
