is there way to allocate yyaxis automatically

I have question about yyaxis i use gui checkbox in matlab

so if i check a and b -> a plot in y left b plot in y right

if i check b and c -> b plot in y left c plot in y right

like this is there way to allocate yyaxis automatically?

if yyaxis left is used i can use yyaxis right

What do you mean? Totally vague

In a GUI I would recommend using explicit handles, so then you have full control over what happens. The fact that you want to use a checkbox to control the things shown is irrelevant: the callback function of the checkbox is just a function, you can let it do whatever you need.

It is very interesting for me.

Two conditions have to be fulfilled

1) Maximum plot not allow more than 3, so it ensure your graph don't have 3rd yaxis.

2) How you program know that how many plot have been done on your graph/axes?

Assign a value to handle first if you are using guide GUI

handles.countplot = 0

then in your call back function of checkbox

    if handles.checkbox.Value == 1
          handles.countplot = handles.countplot + 1;
          % call your plot function 
    else handles.checkbox.Value ==0
         handles.countplot = handles.countplot - 1;
         % call your plot function
    end

In your call function for plot,

if handles.countplot == 0
          % plot what you want.
elseif handles.countplot ==1
         % plot what you want.
         yyaxis left
elseif handles.countplot ==2
         % plot what you wat.
         yyaxis right
elseif handles.countplot >2
      %remind or do some action to restrict user to plot more than 3 graph
end

wow i'll do it on this way right now and let you know soon

[Kevin Chng]

How about your trial?

[woongki park]

when i check more than 2 check box.what should i do?(handles.countplot>2)

Hi Wongki,

Do you want to plot more than 3plot in a graph? In your original question, i guess you want maximum 2 plot in the same axes.if more than 3, warn your user.
