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
