Data cursor showing X and Y positions but showing z position as 0

I have no idea why this is happening, the image shows that there is clearly a value for the z axis but Data cursor is just showing 0. Any way of solving this?

Many thanks

Is this disparity map? If so, find the Point Cloud to get z values.

Based upon the format of the data values being reported, I deduce that you are using pcolor(YourData) to display the data. You should instead use

surf(YourData);
view([0 90]);
axis tight
