MATLAB - 2D Plotting

Aplot(x1, y1, 'r'); plot(x2, y2, 'g'); plot(x3, y3, 'b'); hold on; hold off;

Bhold on; plot(x1, y1, 'r'); plot(x2, y2, 'g'); plot(x3, y3, 'b');

Cplot(x1, y1, 'r'); hold on; plot(x2, y2, 'g'); plot(x3, y3, 'b'); hold off;

Dplot(x1, y1, 'r'); hold off; plot(x2, y2, 'g'); hold on; plot(x3, y3, 'b');

Step-by-Step Solution

Solution:

Step 1: Use hold on after first plot to combine multiple plots
After plotting the first data set, hold on keeps the figure active for additional plots.
Step 2: Plot all data sets with specified colors and then reset with hold off
Plotting the second and third data sets adds them to the same figure. Calling hold off resets plotting behavior for future plots.
Final Answer:
plot(x1, y1, 'r'); hold on; plot(x2, y2, 'g'); plot(x3, y3, 'b'); hold off; -> Option C
Quick Check:
hold on after first plot, hold off after last plot [OK]

Quick Trick: hold on after first plot, hold off after last [OK]

Common Mistakes:

Not calling hold off after multiple plots
Calling hold on before first plot
Mixing hold on and hold off incorrectly
