How can you enable rasterization for a bar plot in matplotlib?
AUse <code>plt.bar(x, height, rasterized=True)</code>
BCall <code>plt.bar(x, height).set_rasterized(True)</code>
CSet <code>rasterize=True</code> inside <code>plt.bar()</code>
DRasterization is not supported for bar plots
Step-by-Step Solution
Solution:

  1. Step 1: Check bar plot rasterization support

    Matplotlib allows rasterization on plot elements but not directly via rasterized argument in plt.bar().

  2. Step 2: Correct method

    After creating the bar container, call set_rasterized(True) on the returned container to enable rasterization.

  3. Final Answer:

    Call plt.bar(x, height).set_rasterized(True) -> Option B

  4. Quick Check:

    Rasterize bar plot by setting property on container. [OK]
Quick Trick: Use set_rasterized(True) on bar container [OK]
Common Mistakes:
  • Passing rasterized=True directly to plt.bar()
  • Using rasterize instead of rasterized
  • Assuming bar plots cannot be rasterized
