How do I combine multiple plots in a for loop?
230 views (last 30 days)
I am trying to plot within a for loop, but it only plots the last value, as it's overwritting previous values. My code look like the following:
BLOCK = 5x1 cell array
TIME = 5x1 cell array
Not sure how to get this, so it doesn't overwrite previous values. Thank you

Add “hold on” prior to your for-loop.
Adding a "hold on" command means that anything that you plot will not clear the existing graph, but just plot on top of what is already there. You can turn off this functionality with the "hold off" command.
for k = 1:length(BLOCK)
if k == 1

I needed to plot graph of frames Vs pixel difference. And the plot was supposed to be inside the for loop. So after seeing this answer I solved one issue, that i update the graph using update. But i want all the points to be connected. Can you help me with it ?
Here is my code
for f = startingFrame+1 : finalFrame
frame = aviread(inFile, f);
i2 = frame.cdata; %cdata — The image data stored as a matrix of uint8 values. The dimensions of F.cdata are height-by-width-by-3.
ig2 = rgb2gray(i2);
[c2,n2] = imhist(ig2);
d = pdist2(c1',c2','cityblock');
if (d > 0.2150) %%change the threshold
c1 = c2;
m = im2frame(i2);
mov = addframe(mov,m);
axis([1 95 0.16 0.26]);
f = frame, d = pixel difference which lies between 0.16 - 0.26 </matlabcentral/answers/uploaded_files/20313/asd.PNG>
