Maze Generation Algorithm Plotting Error

Hey guys, I'm trying to write a script that generates a maze. Normally it works fine, but when i try to utilize the uiaxes function, and try to plot it there, I get only a straight line. I've saved the maze in a 2D Matrix. I have 0 clue where my mistake is. Can someone help me out?

Below is the section of code that I'm using to plot the maze.

displayMaze(displayMaze == 1) = NaN;
maze_show = uiaxes;
maze_show.Position = [30 36 326 250];
maze_show.XLim=[0 2*rows+2];
maze_show.YLim=[0 2*cols+2];
for count = 1: length(displayMaze);
     temp = displayMaze(count,:);
     temp(~isnan(temp)) = count;
     displayMaze(count,:) = temp;
     plot( maze_show,displayMaze(count,:),'k','linewidth',2.5)
     hold on
end
for count =1: length(displayMaze)
    plot(maze_show,count*ones((length(displayMaze)),1),displayMaze(:,count),'k','linewidth',2.5)
    hold on
end

According to Display Graphics in App Designer,

hold on

uses gca and gcf to decide which axes to hold, but can't see UIAxes objects.

You should explicitly specify which axes to hold:

hold(maze_show,'on')

Hi,

While using “UIAxes” object for plotting, it is important to specify the “UIAxes” object as first argument for the hold functions. The following changes to the code will resolve your issue:

Replace

hold on 

With

hold(maze_show,'on') 

Please refer to “UIAxes” documentation for more information.

Hope this helps.
