You're doing something like calling xticks() or xticklabels() with only two values. Please show us all the code involved in creating your graph. You need to be doing something like

xticks([0, max(x)]);

instead of whatever you're doing.

tahnks from all of you:

1: if we see in graph it start from between 7 and 8 AM , i want to strat this from 7 AM .

2: if we look at graph wecan not see graph end because it is hide so i want to see the last end of graph and it should some on 6pm .

3: i want to put name one above of each graph i mean Tw should come on Tw graph and T2 should come on T2 graph and so on .

thanks you so much dear

[drummer]

xlim[yourInitialRange, yourEndRange]
% Specifically
xlim[0, 100]; % check if it works.

Actually, I noticed the right side in your graph.

You want your graphic to start at 0 from the left, or in the middle and goes negative to the left and positive to the right?
