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

开发者_开发问答How do I find the minimum and maximum of the axis in a MATLAB plot?

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.

If you mind going the properties way use

xlim ylim or zlim to retrieve min and max value or

xlim([minValue maxValue]) to set the limits.

See set or query axis limits for additional parameters.
