MATLAB: How to apply “axis equal” to only two directions while visualizing volume data

axis equalvolume dataz axis

I am trying to use "slice" function to plot volume data. And the x- and y-axis need to be scaled equally, but the z-axis need not. However, the "axis equal" command will influence every axis. Is there a way to change that

I haven't really used 'axis equal' much but it is just a convenience function. The help documentation actually gives details of which properties change for the various axis styles.

In this case it says that 'DataAspectRatio' is set to [1 1 1] and PlotBoxAspectRatio to [3 4 4].

To be honest the latter setting is a bit of a mystery to me, but the first you could just set yourself to always be the same for x and y while leaving z independent. PlotBoxAspectRatio just affects the relative length of the various axes though, not their domain values.

If you don't hold the plots, axis limits will be reset every time you call plot. For an animation, you can use hold and either delete plotted objects or change their data. That is,

hold on
h = plot(1:10); 
<grab animation frame here>
delete(h) 
h = plot(1:20);

and so on. Or you can change the data in h with

set(h,'xdata',1:20,'ydata',1:20)
