hard📝 Application Q8 of 15
Step-by-Step Solution
Solution:
Step 1: Understand how to color points by values
Use the 'c' parameter to pass an array of values for coloring points.Step 2: Use a colormap to map values to colors
Specify cmap='viridis' to apply a color gradient based on z values.Final Answer:
ax.scatter(x, y, z, c=z, cmap='viridis') -> Option AQuick Check:
Color points by values using c=values and cmap [OK]
Quick Trick: Use c=values and cmap for color mapping in scatter [OK]
Common Mistakes:
- Passing string 'z' instead of array z
- Using color='z' which is invalid
- Omitting c parameter
