Hi i have 3 plots in same figure,i want 3 checkboxes each plot and its corresponding axis shold be assigned to individal checkboxes. when i uncheck the checkbox plot and axis corresponding to that checkbox should be disappeared and again when i check the checkbox plot and axis of that checkeckbox should be displayed.here is my code,please help
x = 0:20;
N = numel(x);
y1 = rand(1,N);
y2 = 5.*rand(1,N)+5;
y3 = 50.*rand(1,N)-50;
%# Some initial computations:
axesPosition = [110 40 200 200]; %# Axes position, in pixels
yWidth = 30; %# y axes spacing, in pixels
xLimit = [min(x) max(x)]; %# Range of x values
xOffset = -yWidth*diff(xLimit)/axesPosition(3);
%# Create the figure and axes:
figure('Units','pixels','Position',[200 200 330 260]);
h1 = axes('Units','pixels','Position',axesPosition,...
'Color','w','XColor','k','YColor','r',...
'XLim',xLimit,'YLim',[0 1],'NextPlot','add');
h2 = axes('Units','pixels','Position',axesPosition+yWidth.*[-1 0 1 0],...
'Color','none','XColor','k','YColor','m',...
'XLim',xLimit+[xOffset 0],'YLim',[0 10],...
'XTick',[],'XTickLabel',[],'NextPlot','add');
h3 = axes('Units','pixels','Position',axesPosition+yWidth.*[-2 0 2 0],...
'Color','none','XColor','k','YColor','b',...
'XLim',xLimit+[2*xOffset 0],'YLim',[-50 50],...
'XTick',[],'XTickLabel',[],'NextPlot','add');
xlabel(h1,'time');
ylabel(h3,'values');
%# Plot the data:
plot1=plot(h1,x,y1,'r');
plot2=plot(h2,x,y2,'m');
plot3=plot(h3,x,y3,'b');

Code for the checkboxes uicontrol:
hax = [h1;h2;h3]; % axes handles
hcb = [0;0;0]; % checkbox handle (preallocate)
cb_text = {'r ','m ','b '}; % checkbox text
for i = 1:3
hcb(i) = uicontrol('Style','checkbox','Value',1,...
'Position',[-30+i*40 1 40 15],'String',cb_text{i});
end
set(hcb,'Callback',{@box_value,hcb,hax});
And the callback function:
function box_value(hObj,event,hcb,hax) %#ok<*INUSL
% Called when boxes are used
v = get(hObj,'Value');
I = find(hcb==hObj);
%[axes visibility]:
s = {'off','on'};
ycol_r = {[1 1 1]*0.8,'r'}; % ycolor for red plot axes
if I == 1
set(hax(I),'YColor',ycol_r{v+1})
else
set(hax(I),'Visible',s{v+1})
end
%[line visibility]:
hl = findobj(hax(I),'Type','line'); % line handles
set(hl,'Visible',s{v+1})
The function turns the visibility for axes and plot on and off. Your red axes cant be turn off, because its needed for the other axes. Thats why just the yaxis color is changed to the background color.

You're going to have to create checkboxes. Why not use GUIDE? Just place them on the window and right click and go to the callback and put in your code. Otherwise you'll have to do the same thing for checkboxes like you did with the axes and that's tedious.
Do you know that if you turn the axes off or make them invisible, that only affects the two axes (x & y) and the tick marks and labels? The background and stuff plotted or displayed in the axes will still be there - probably not what you want or were expecting. A work about is to put the axes in a panel and then you can turn the panel's visibility on or off and that will hide the entire axes and all its contents.
So, in the callback for the axes you can turn the panels on or off, or maybe you just want to call "cla reset" on the appropriate axes.

In GUIDE, click on a control such as a checkbox or an axes in the panel of available controls. Click and drag it out to the size you want on the figure. See Doug Hull's videos for quick and easy basic training on GUIDE: http://blogs.mathworks.com/videos/category/gui-or-guide/
