How to program a push button which will display the graphs signal filter

HELLO!

I have small GUI, which will show me 4 graphs from the text file data measured by the phone's accelerometer.

I created the code for a simple moving average filter which is displayed in graphs for individual axes (acceleration in the axis X,Y,Z + speed).

However, these filters are always displayed in the graphs, but I would like to program a pushbutton to show and disappear these filters for individual graphs. Could someone please advise me how to do this?

I'm new to programming and can't figure this out, THANKS!!

Here is my code that permanently display the filter on the x-axis acceleration graph:

         % signal smoothing - a moving average filter
          samplesPerSec=100;
          coeff=ones(1,samplesPerSec)/samplesPerSec;
          avgx=filter(coeff,1,x);
          fDelay = (length(coeff)-1)/57.7;
          tdx=t-fDelay/86;
          L2=line(tdx,avgx, 'color', 'blue', 'linewidth',2, 'parent', ax1);
          L=[L1 L2]; % handle
          ax1=gca;

You can set the Visible property of the line object handles to 'off' to hide them. Set them off in your button callback.

x = (1:10)';
y = rand(10,1);

h = line(x,y);

c = uicontrol;
c.String = 'Hide';

c.Callback = @(s,e)hide(h);

function hide(h)
h.Visible = 'off';
end

Thanks a lot! Could I ask what the code would look like for multiple lines in individual graphs (see original image above)? The code works for the filter in the first graph, but I don't know how to program it for all the filters in the other graphs.

For each line that you want to turn on/off, store their handles in a variable, similar to what you do in your code:

subplot(211)
L1 = line(1:10,rand(1,10));

subplot(212)
L2 = line(1:10,rand(1,10));

L=[L1 L2]; % handle

Then you can turn off a given line at index k using the code:

k = 2;
L(k).Visible = 'off';
