Reanimate.Builtin.TernaryPlot
Description
Implementation of ternary plots: https://en.wikipedia.org/wiki/Ternary_plot
Synopsis
- type ACoord = Double
- type BCoord = Double
- type CCoord = Double
- ternaryPlot :: Int -> (ACoord -> BCoord -> CCoord -> PixelRGBA8) -> Tree
- toCartesianCoords :: ACoord -> BCoord -> (Double, Double)
- toOffsetCartesianCoords :: ACoord -> BCoord -> (Double, Double)
- fromCartesianCoords :: Double -> Double -> (ACoord, BCoord, CCoord)
Documentation
Arguments
| :: Int | Pixels in the X-axis. More pixels => higher quality. |
| -> (ACoord -> BCoord -> CCoord -> PixelRGBA8) | a+b+c=1. A=1 is the left-most position, B=1 is the top-most position, and C=1 is the right-most position. |
| -> Tree |
Creates a centered ternary plot with a width of 5.
Example:
ternaryPlot 100 $ \aCoord bCoord cCoord -> promotePixel $
let red = round $ aCoord*255
green = round $ bCoord*255
blue = round $ cCoord*255
in PixelRGB8 red green blue
toCartesianCoords :: ACoord -> BCoord -> (Double, Double) Source #
Compute the XY coordinates from ternary coordinates.
Note that CCoord is given because a+b+c=1.
