MATLAB: Slider for Multiple Plots in GUIDE

guiguide

I need to be able to scroll through 10 graphs on a single

axis in GUIDE. I don't know where to start.

So the widgets I'm using is one axis, slider, and pushbutton for access

to axis.

So for push button 1:

I plot 10 different plots on the same data.

Now I want it to be able to scroll through each plot.

I really don't know where to begin on this. A code example

would be appreciated.

Thanks,

Amanda

Here is a simple example GUI. Note that the same principle applies in GUIDE.

function [] = slider_plot()
% Plot different plots according to slider location.
S.fh = figure('units','pixels',...
              'position',[300 300 300 300],...
              'menubar','none',...
              'name','slider_plot',...
              'numbertitle','off',...
              'resize','off');    
S.x = 0:.01:1;  % For plotting.         
S.ax = axes('unit','pix',...
            'position',[20 80 260 210]);
plot(S.x,S.x,'r');        
S.sl = uicontrol('style','slide',...
                 'unit','pix',...
                 'position',[20 10 260 30],...
                 'min',1,'max',3,'val',1,...
                 'sliderstep',[1/2 1/2],...
                 'callback',{@sl_call,S});  
function [] = sl_call(varargin)
% Callback for the slider.
[h,S] = varargin{[1,3]};  % calling handle and data structure.
cla
switch round(get(h,'value'))
      case 1
          cla
          plot(S.ax,S.x,S.x.^1,'r')
      case 2
          cla
          plot(S.ax,S.x,S.x.^2,'b')        
      case 3
          cla
          plot(S.ax,S.x,S.x.^3,'k')         
      otherwise
          disp('cannot plot')
  end

Right click your slider in GUIDE and view the callback function. Then put this code in there:

% First get S.  See the FAQ for methods to do that.
% http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F
sliderValue = int32(get(handles.slider1, 'Value'));
switch sliderValue 
    case 1
        cla;
        plot(S.ax,S.x,S.x.^1,'r');
    case 2
        cla;
        plot(S.ax,S.x,S.x.^2,'b');        
    case 3
        cla;
        plot(S.ax,S.x,S.x.^3,'k');        
    otherwise
        message = sprintf('No case for slider value of %d', sliderValue);
        uiwait(warndlg(message));
end

Here is an example.

function [S] = scroll_plot()
% Scroll through 8 plots.
S.fh = figure('units','pixels',...
              'position',[500 500 200 260],...
              'menubar','none',...
              'name','scroll_plot',...
              'numbertitle','off',...
              'resize','off');
S.sl = uicontrol('style','slide',...
                 'unit','pix',...
                 'position',[180 10 20 240],...
                 'min',1,'max',8,...
                 'sliderstep',[1/7 1/7],...
                 'value',1); 
S.V = 1;  % The value of the slider.           
x = 0:.01:1;  % Make plots.
for ii = 0:7 
    S.ax(ii+1) = axes('units','pix','pos',[20 30+(260*ii) 150 220]);
    plot(x,x.^ii);
end
set(S.sl,'callback',{@sl_call,S})
function [] = sl_call(varargin)
% Callback for slider.
S = varargin{3};  % Get the structure.
V = get(S.sl,'value');
for ii = 0:7
    P = get(S.ax(ii+1),'pos');
    set(S.ax(ii+1),'pos',P-[0 260*(sign(V - S.V)) 0 0])
end
S.V = V;
set(S.sl,'callback',{@sl_call,S});
