Enum sampling::heatmap::GnuplotPalette[][src]

pub enum GnuplotPalette {
    PresetHSV,
    PresetRGB,
    CubeHelix(CubeHelixParameter),
    RGB(PaletteRGB),
}
Expand description

defines presets for different color palettes

Variants

PresetHSV

Use preset HSV palette

PresetRGB

Use preset RGB palette, i.e., the default palette of gnuplot

Use a CubeHelix palette

What makes this palette special is, that, if it is converted to black and white, it will be monotonically increasing in perceived brightness (or monotonically decreasing, if you reverse the palette), which is nice for heatmaps
