Represent the figures on the XZ (or YZ) plane

Hi! I would like to modify my code so that the figures are shown on the XZ (or YZ) plane and not on the XY plane (as in my code).

How can I modify it?

clc;    % Clear the command window.
fprintf('Beginning to run %s.m ...\n', mfilename);
close all;  % Close all figures (except those of imtool.)
clearvars;
workspace;  % Make sure the workspace panel is showing.
format short g;
format compact;

myFolder = 'C:\Users\...';

filePattern = fullfile(myFolder, '*.png');
imageFiles = dir(filePattern);
hFig3 = figure('Name', '3D Plot', 'NumberTitle', 'off');

% z-coordinates to use:
z = 1+100*(0:numel(imageFiles)-1); %[1 101 201 ...]

for k = 1:length(imageFiles)
    baseFileName = imageFiles(k).name;
    fullFileName = fullfile(myFolder, baseFileName);
    fprintf(1, 'Now reading %s\n', fullFileName);
    imageArray = imread(fullFileName);
    drawnow;
    % Call pic2points.  This will open a new figure.
    CoordinateMatrix = pic2points(imageArray);
    % Switch to the figure for the 3-D plotting:
    figure(hFig3);
    % scatter(CoordinateMatrix(:, 1), CoordinateMatrix(:, 2), '.');
    current_z = z(k) * ones(size(CoordinateMatrix, 1), 1);
    plot3(CoordinateMatrix(:, 1), CoordinateMatrix(:, 2),  current_z, '.');
    hold on
    drawnow;
end
grid on;
hFig3.WindowState = 'maximized';
fprintf('Done running %s.m.\n', mfilename);
xlabel('axis X')
ylabel('axis Y')
zlabel('axis Z')

XY plane (current):

plot3(CoordinateMatrix(:, 1), CoordinateMatrix(:, 2),  current_z, '.');

XZ plane:

plot3(CoordinateMatrix(:, 1), current_z, CoordinateMatrix(:, 2), '.');
% or
plot3(CoordinateMatrix(:, 2), current_z, CoordinateMatrix(:, 1), '.');

YZ plane:

plot3(current_z, CoordinateMatrix(:, 1), CoordinateMatrix(:, 2), '.');
% or
plot3(current_z, CoordinateMatrix(:, 2), CoordinateMatrix(:, 1), '.');
