Choice between legends and curves

Hi,

I have in one plot more curves.

If I press pushbutton1, then I need to show off legend1 and also curve1. If I press again pushbutton1, then I need to show on legend1 and also curve1.

If I press pushbutton2, then I need to show off legend2 and also curve2.If I press pushbutton2, then I need to show on legend2 and also curve2. . . . Please, can you help me

How can I close axis 1? If I use this code:

for i=1:7
  handles.speed(:,i)=(s/t)';
  plot(t',handles.speed);
  cla(handles.speed(:,1),'reset');
  end;

I gor error Bad handle

Here is how I would go about this:

function showTwoLines
    %two lines and their legend
    hFig = figure;
    hL(1) = plot(1:10);
    hold on
    hL(2) = plot(rand(1,10));    
    legend(hL, 'Line 1','Line 2')

      %two pushbuttons.  Note the callback passes in the line handles and the line of choice index.
      uicontrol('Style','pushbutton',...
            'Units','normalized',...
            'Position',[0.1 0.05 0.3 0.1],...
            'String','One!',...
            'Callback',@(~,~)ToggleLines(hL,1));        
      uicontrol('Style','pushbutton',...
            'Units','normalized',...
            'Position',[0.4 0.05 0.3 0.1],...
            'String','Two!',...
            'Callback',@(~,~)ToggleLines(hL,2));

end
function ToggleLines(hL,idx)

      set(hL(setdiff(1:numel(hL),idx)),'visible','off'); %turn other lines off
      set(hL(idx),'visible','on'); %turn line of choice on
      legend(hL(idx),sprintf('Line %i',idx)); %add legend

end

Save the above to showTwoLines.m

Hi, I make code in gui.

I need use checkbox. I need generate for example 10 checkboxes. Count of checkboxes is always different.

How can I change your callback? If checkbox1 is one, then show line one. If it is off, then show off line one. Checkbox1 does not affect the others checkboxes.

Hi John, I should have some time to augment the example later.

OK, I will wait, thanks

Is there anything new?
