How do i get the upper (and lower) limits of an axis in MATLAB?

Question

How do I find the minimum and maximum of the axis in a MATLAB plot?

Answer 1

Here's how you can do it for the current axes (i.e. gca):

xLimits = get(gca,'XLim');  % Get the range of the x axis
yLimits = get(gca,'YLim');  % Get the range of the y axis
zLimits = get(gca,'ZLim');  % Get the range of the z axis

Each variable above will be a 1-by-2 array containing the minimum and maximum values for the respective axis. You can check the documentation on axes properties for more information.
