Question

Given a matrix:

B

ans =

   30.7805   28.7527   25.7110   23.6832   19.6268   17.5949   14.5547   11.5147    8.4725    5.4313

    5.4313    4.4159

I am trying to plot the data as shown in this image:

http://postimage.org/image/2wwighvs4/

I am trying to plot the 1st column as the orange points and the 2nd column as the blue points. The time between the points form a small box. The only axes I'm interested in is the X which will be composed of the overall time of the video. I am attempting to do this in a GUIDE axes. Eventually I want the user to be able to select the points and add labels.

Any advice in accomplishing this will be greatly appreciated!

Answer 1

a =[30.7805   29.7667
   28.7527   27.7333
   25.7110   24.6923
   23.6832   21.6549
   19.6268   18.6114
   17.5949   15.5708
   14.5547   12.5285
   11.5147    9.4806
    8.4725    7.4582
    5.4313    4.4159]
axis([0,max(a(:))+max(a(:))/5,0,2])
hold on
plot(a(:,1),1,'pb')
plot(a(:,2),1,'pr')
h=0.02;y=1;
arrayfun(@(n)rectangle('EdgeColor','y','Position',...
[min([a(n,1) a(n,2)]),y-h,abs(a(n,1)-a(n,2)),2*h]),1:size(a,1))
%with numbers if you want them:
arrayfun(@(n)text(min([a(n,1) a(n,2)]),y+2*h,...
num2str(size(a,1)-n+1)),1:size(a,1))
