Hi all,

Is there a way to create a subplot like the lower one in the picture?

I have 2 matrices for the statuses of n machines, one for the ONs, one for the standbys, S_on and S_sb. A '1' in each of those matrices represents on or standby, '0' in both mean off. To create the final matrix with the power Consumption, each of them will be multiplied with a Power vector.

Now I want to create a status bar beneath indicating when the machine is ON, standby or OFF. How do I plot this? Thank you so much for your help!

Simon

在 MATLAB Online 中打开

x=[0 1  1   2   2  4  4  5  ]
y=[2 2  1   1  0   0   2  2]
subplot(211),plot(x,y)
subplot(212),
in={'off','sb','on'}
cl={'g','b','y'}
for k=1:numel(x)/2
  xx=x(2*k-1:2*k ) 
  plot([ xx fliplr(xx) xx(1)],[0 0 1 1 0],cl{y(2*k)+1},'linewidth',12)
  text(mean(xx),0.5,in{y(2*k)+1},'fontsize',12)
  hold on
end
hold off

Hi Azzi,

thank you for your help! I tried to alter the code to fit my question, but could not do so. How can I make the code work for a continuous x? Like x=[0 1 2 3 4 5 ...] and that for y=2 ON is displayed, y=1 sb and y=0 OFF without gaps? When I just change it in your code, I get "discrete" bars with gaps in between.

Again, thank you for your help!

Simon
