PosePlot - Y and Z Axes cannot be reversed

When using the poseplot() tool in Matlab 2023a. Only the X axis can be manipualted. The Y and Z axes cannot be changed. Wondering if this is a bug or if there is another mechanism to reverse the axes.

%% Example Code
% Convert euler angles to quaternion
q = quaternion([30,45,60],'eulerd','XYZ','point')

% Create a poseplot
poseplot(q)

% Try and reverse the axes
set(gca,'ZDir','Reverse')
set(gca,'YDir','Reverse')
set(gca,'XDir','Reverse')  % Only X works

hello

well , your Y and Z directions are already 'reverse' in first place, while Xdir was 'normal'

so if you wanted to change all 3 directions you needed to do

set(gca,'XDir','Reverse')

set(gca,'YDir','normal')

set(gca,'ZDir','normal')

%% Example Code
% Convert euler angles to quaternion
q = quaternion([30,45,60],'eulerd','XYZ','point')

q = quaternion
     0.82236 + 0.02226i + 0.43968j + 0.36042k

% Create a poseplot
poseplot(q)
get(gca)

% Try and reverse the axes
set(gca,'XDir','Reverse')  % Only X works
set(gca,'YDir','normal') % Y works too
set(gca,'ZDir','normal') % Z works too

[Euan]

Ah amazing, I hadn't realised that:

set(gca,'YDir','Reverse')

actually set the position to "reverse" I thought it just flipped the axis.

Plot is working great now.
