Why does MATLAB's
colormap function affect all plots in the current figure rather than just one axes?Why does MATLAB's colormap function affect all plots in the current figure rather than just one axes?
hard📝 Conceptual Q10 of 15
Step-by-Step Solution
Solution:
Step 1: Understand colormap scope
In MATLAB, colormap is a property of the figure, so all axes inside share the same colormap.Step 2: Exclude other options
colormap is not global across figures, axes do not have independent colormaps by default, and colorbar does not override colormap.Final Answer:
Because colormap is a figure-level property shared by all axes -> Option BQuick Check:
colormap scope = figure-level property [OK]
Quick Trick: Colormap applies to entire figure, not individual axes [OK]
Common Mistakes:
- Thinking colormap is global across all figures
- Assuming axes have separate colormaps
- Confusing colorbar with colormap control
