Expand description

Color map options for density plots

This enum provides access to a wide variety of colormaps suitable for scientific data visualization. Colormaps are categorized into:

  • Perceptually uniform sequential: Viridis, Plasma, Inferno, Magma, Turbo (excellent for continuous data, colorblind-friendly)
  • Traditional: Rainbow, Jet (colorful but less perceptually uniform)
  • Grayscale: Bone, BlackWhite (useful for printing)
  • Specialized: Mandelbrot, Volcano (artistic/experimental)

§Recommendations

  • Default choice: Viridis - perceptually uniform, colorblind-friendly
  • High contrast: Plasma, Inferno, Magma - good for presentations
  • Traditional: Rainbow, Jet - colorful but use with caution
  • Print-friendly: Bone, BlackWhite - grayscale options
