MATLAB: Linking a graph to a pushbutton

graphgui

I HAVE A GUI THAT HAS 5 GRAPHS,

1.FFT

2.PSD

3.TIME DOMAIN PLOT

etc….

NOW I WANT EACH TO BE PLOTTED ON GRAPHS BY PRESSING PUSH BUTTONS SEPARATELY. BUT THE PROBLEM IS THAT THE GRAPHS ARE BEING PLOTTED ON THE SAME AXES EVERY TIME.WHAT SHOULD I DO TO LINK EACH PUSHBUTTON TO SEPARATE GRAPHS. PLSS HELP ME…

You can set each axes as the current axes with the axes commands:

axes(handleToAxes1);
plot(x1, y1);
axes(handleToAxes2);
plot(x2, y2);
axes(handleToAxes3);
plot(x3, y3);

Or send in the axes handle in to the function - most of them take an axes handle as an input argument:

plot(handleToAxes1, x1, y1);
imshow(imageArray, 'Parent', handleToAxes2);
bar(handleToAxes3, x3, y3);

plot(x1, y1);
hold on
plot(x2, y2);
plot(x3, y3);

If you need multiple axes that overlap, do not use subplot() as subplot() automatically erases any axes that the new axes would overlap.

ax1 = axes('Position', [10 10 50 50]);
plot(ax1, x1, y1);
ax2 = axes('Position', [20 20 50 50]);
plot(ax2, x2, y2);
ax3 = axes('Position', [30 10 50 50]);
plot(ax3, x3, y3);

If plot works in an axes with 'NextPlot' set to 'replace' (the default), a new plot replaces the old plot completely. Try this:

function pushbutton1_Callback(hObject, eventdata, handles)
X1=[1 2 3 4];
Y1=[-1 -2 -3 -4];
X2=[1 2 3 4];
Y2=[1 2 3 4];
set(gca, 'NextPlot', 'add');   % Equivalent to: hold('on')
handles.handle_plot1 = plot(X1,Y1);
handles.handle_plot2 = plot(X2,Y2);
guidata(hObject, handles);
