Hello dear matlabbers,

I tried to create a scatterplot with labels for each point (link here: 1).

Now I would like to give the user of the code the possibility to turn the labels on and off. I appreciate any help and comments! Thanks a lot in advance!

So far my code looks like this:

x = rand(1,100); y = rand(1,100); pointsize = 30;
idx = repmat([1 : 10], 1, 10)             % I used class memberships here
figure(1)
MDSnorm = scatter(x, y, pointsize, idx, 'filled');
dx = 0.015; dy = 0.015;                   % displacement so the text does not overlay the data points
T = text(x + dx, y +dy, labels);
colormap( jet );                          % in my code I use a specific colormap
Button = uicontrol('Parent',figure(2),'Style','toggle','String',...
    'labels','Units','normalized','Position',[0.8025 0.82 0.1 0.1],'Visible','on',...
    'callback',{@pb_call, MDSnorm, ???});

At the end of my script I then tried to define the pb_call function. I tried out several different versions, they all failed. Unfortunately, I am not skilled enough to translate any tutorials to my specific problem.

I have a rough idea what I need to do...

function [] = pb_call( ??? )
if get(Button, 'Value')
T --> invisible       % ???
else
T --> visible         % ???
end
end

Try the following method (it might work for you but there are some limitations) :

x = rand(1,100); y = rand(1,100); pointsize = 30;
idx = repmat([1 : 10], 1, 10)             % I used class memberships here
figure(1)
MDSnorm = scatter(x, y, pointsize, idx, 'filled');
dx = 0.015; dy = 0.015;                   % displacement so the text does not overlay the data points
T = text(x + dx, y +dy, labels);
colormap( jet );                          % in my code I use a specific colormap
Button = uicontrol('Parent',figure(2),'Style','toggle','String',...
    'labels','Units','normalized','Position',[0.8025 0.82 0.1 0.1],'Visible','on',...
    'callback',@pb_call);

And the function can be edited as follow:

function pb_call(src,event)
a = gcf; % get the handle for current figure
T = findobj(a,'type','text');
if src.Value == 1
    set(T,'Visible','off')
else
    set(T,'Visible','on')
end
end
