pcshow - rescale axes on 3D pointcloud display

I'd like to rescale the axes shown from pcshow. See attached screeshot. I'd like to input some argument into the pcshow function so as to avoid manually rescaling the axes each time if possible.

Thank you :)

hey, you have to modify the DataAspectRatio property of the point cloud object, which defaults to [1 1 1]!

Here's an example on how to make all axis equal:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

clear all; close all;

% Random point cloud with 1000 (x, y, z) triplets with a dimension of roughly 30x10x5

mat = [round(30*randn(1000,1)),round(10*randn(1000,1)),round(5*randn(1000,1))];

% Show point cloud

ax = pcshow(mat)

% Normalize the data relative to the Y axis

ax.DataAspectRatio = [diff(ax.XLim), diff(ax.YLim), diff(ax.ZLim)] / diff(ax.YLim);

Hope it helps!

That works, thanks!
