MATLAB - 2D Plotting
Find the mistake in this MATLAB code snippet:
plot(1:5, [5 10 15 20 25]);
title('Growth');
xlabel('Time');
ylabel('Value');
legend('Growth Data', 'Extra');
Aylabel() label text is empty
Bxlabel() is missing
Ctitle() syntax is incorrect
Dlegend() has more labels than plotted lines
Step-by-Step Solution
Solution:
  1. Step 1: Count plotted lines and legend labels

    Only one line is plotted but legend() has two labels, causing mismatch.
  2. Step 2: Identify impact of mismatch

    Extra legend label causes MATLAB to throw a warning or error.
  3. Final Answer:

    legend() has more labels than plotted lines -> Option D
  4. Quick Check:

    Legend labels must match number of plot lines [OK]
Quick Trick: Match legend labels count to plotted lines [OK]
Common Mistakes:
  • Adding extra legend labels
  • Forgetting to plot multiple lines
  • Incorrect title syntax
