MATLAB: How to make axes have proportional scales

axisMATLAB

Hi, I would like the x and y axes on my surf plot to have proportional scales. I am plotting temperature over a 2D plane. I want to visualise the temperature profile but the x and y axes stretch to fit the figure window, stretching the temperature profile.

I want the axes to have the same 'unit:distance on screen' ratio. How can I do this? I have been finding the aspect ratio help not very helpful Thanks

If you want them to have equal scales then

axis equal

Otherwise set the axes DataAspectRatio property. For example,

set(gca,'DataAspectRatio',[10 1 1])

would mean that every 10 units of x is to have the same size as one unit of y -- which would make something of x width 10 and y height 1 into a square.

Check out linkaxes and linkprop. Use them to set the axis limits and, if needed, other axis properties between two axes.

The reason why your set() command didn't work is because you need to specify the axis handle.

set(app.UIAxes,'DataAspectRatio',[10 1 1])
%   ^^^^^^^^^^ or whatever your axis handle is

Reduce the height of the first axis

% This reduced the height to 80% 
% Play around with the value to get what you want
ax1.Position(4) = ax1.Position(4)*.80;

Then link the ax1 and ax2 axes.

linkaxes([ax1,ax2])
