- Python code examples showcasing different color maps
Color Maps in Matplotlib
Color maps, also known as colormaps, are used in Matplotlib to visually represent discrete data points or continuous data ranges. They enable you to convey information through appealing visualizations.
| Color Map | Description |
|---|---|
| viridis | The viridis color map is a diverging color map, which distinguishes between warm and cool colors. |
| magma | The magma color map is another diverging color map, presenting colors from hot, through neutral, to cold. |
| coolwarm | The coolwarm color map is a diverging color map that transitions smoothly from cool to warm colors. |
| hot | The hot color map is a diverging color map that presents colors from cold to hot. |
| inferno | The inferno color map is a diverging color map that starts dark and gradually transitions to light colors. |
| cool | The cool color map represents a diverging color cycle, transitioning from cool to warm colors. |
| magma | The magma color map is another diverging color map that transitions from cool to hot colors. |
| viridis | The viridis color map is a diverging color map that presents colors from cool to warm. |
| plasma | The plasma color map is a diverging color map that transitions from cold to hot colors. |
| magma | The magma color map is a diverging color map that transitions from cool to hot colors. |
| cool | The cool color map represents a diverging color cycle transitioning from cool to warm colors. |
