Beginner's question about data plot
1 view (last 30 days)

The data used for this plot is a series of 0's followed by a series of 1's, then back to 0's. I expected to see a 0-1-0 pulse shaped signal starting at around 15 minutes and ending just before 50 minutes, but instead I see a starting and trailing slope. What causes this behavior? The code is as simple as it gets:
figure(1), plot(time,Enable_d)
title('Signal Enabled')
xlabel('Time (min)')

How you expected to switch from 1 to 0, in plot its connect both data points have you look at stem?
figure(1), stem(time,Enable_d)
title('Signal Enabled')
xlabel('Time (min)')

Try this instead
plot(time,Enable_d,'.','MarkerSize',32)
This code will plot individual points, without a connecting line.

How do you expect MATLAB to "know" how to fill in the gap from 15 to 40? How can it know you want it to be 1 right after Time = 15, rather than 0, or 0.5, or 0.73245?
The answer is -- MATLAB can't know what to plot there unless to program it to.

To get a plot with sharp, not sloping, edges, use stairs() or bar().
