Why does this code raise an error?
import matplotlib.pyplot as plt
plt.scatter([1,2,3], [4,5], rasterized=True)
plt.show()
AThe x and y data lengths differ, causing a ValueError.
BRasterization is not supported for scatter plots.
Cplt.scatter requires 'rasterize' instead of 'rasterized'.
Dplt.show() must be called before plotting.
Step-by-Step Solution
Solution:
  1. Step 1: Check data lengths

    X data has 3 points, Y data has 2 points, causing mismatch error.
  2. Step 2: Validate rasterization and function usage

    Rasterization is supported and parameter spelling is correct; plt.show() usage is correct.
  3. Final Answer:

    The x and y data lengths differ, causing a ValueError. -> Option A
  4. Quick Check:

    Data length mismatch = ValueError [OK]
Quick Trick: Ensure x and y data lengths match [OK]
Common Mistakes:
  • Blaming rasterization for error
  • Using wrong parameter name
  • Calling plt.show() too early
