How to show first value on axis cuted with xlim?

I am using xlim to make my axis shorter, but on that way Matlab does not show me first value on shorter axis.

More detailed: I am using command xlim([1 21]); and I need that number 1 on the x axis. How should I correct that, instead of using some graphic programs?

This zero on picture is from vertical axis, I am looking for the first value on the horizontal axis.

Altering the xlim is not going to change the automatic tick calculation, which tries for 4 to 5 ticks at nice "round" numbers. If you want the first value labeled you need to put in an xtick there.

xticks( [1, xticks()] )

I just tried your way and I am getting the zero showing up on the x-axis so I'm not sure what is going on there.

As an alternative you could try using axis instead and see if that helps.

axis([x_min x_max y_min y_max])

Maybe I did not explain on the correct way. I am using command xlim([1 21]); and I need that number 1 on the x axis.

With

axis([x_min x_max y_min y_max])

as you suggested is the same, without 1 on x axis.

Sorry, that's my fault.

In that case you'll need to change the tick locations - see the below for more information.
