Axis Values in a Figure

Question

Dan 2013-2-13

I draw a figure using:

colormap(hot(num_colors));
image(myMatrix);

The values in the x and y axis are automatically shown in the figure. I want my values to be shown in the x,y axis.

I have two sets of custom strings xvals and yvals, how do I simply append these values to the corresponding axis in the figure?

To change the tick mark labels you can do something like:

set(gca,'YTickLabel',yvals);
set(gca,'XTickLabel',xvals);

where yvals and xvals are cell arrays of strings. To then change the positions of the tick marks you can use:

set(gca,'YTick',yval_num);
set(gca,'XTick',xval_num);

where xval_num and yval_num are arrays of numbers specifying the values at which to put the tick marks.
