How do i set limits on the graph scale similar to colormap

I currently have a code which runs the scale from the highest number to the lowest number in the matrix table given; How do i set the 'XTick' to a predetermined value say from 0-40

It seems you already know how to set the xticks to a set value, as per your code

set(axishandle, 'XTick', 0:40);

So it's really not clear what you're asking.

I was talking about the color map section; How do i set a predetermined scale for the color map say from 0-40 for every data i run?

You can set the colour map limit with caxis or by changing the clim property of the axis.
