blob :: AlphaColour Double -> RectOptions Source #
solid rectangle, no border
box :: AlphaColour Double -> RectOptions Source #
clear rect, with border
clear :: RectOptions Source #
clear and transparent rect
bound :: RectOptions -> Double -> Chart b -> Chart b Source #
place a rect around an Chart, with a size equal to the chart range
rect_ :: (N b ~ Double, V b ~ V2, Transformable b, HasOrigin b, TrailLike b, HasStyle b) => RectOptions -> Rect Double -> b Source #
A single rectangle specified using a Rect x z y w where (x,y) is location of lower left corner (z,w) is location of upper right corner
let opts o = def {labelText = (labelText def) {textColor=withOpacity black 0.8, textSize = 0.3}, labelOrientation=o} labelled (opts (Pair 2 1)) ("z,w") $ labelled (opts (Pair -2 -1)) ("x,y") (rect_ def (Ranges (2*.one) one))
rects :: (V a ~ V2, N a ~ Double, Functor t, HasStyle a, TrailLike a, HasOrigin a, Transformable a, Foldable t, Monoid a) => RectOptions -> t (Rect Double) -> a Source #
Create rectangles (with the same configuration).
rects def (rectOneD [1, 2, 3, 5, 8, 0, -2, 11, 2, 1])
rectChart :: Traversable f => [RectOptions] -> Aspect -> Rect Double -> [f (Rect Double)] -> Chart b Source #
A chart of rects
rectChart_ :: Traversable f => [RectOptions] -> Aspect -> [f (Rect Double)] -> Chart b Source #
A chart of rectangles scaled to its own range

At some point, a color of a rect becomes more about data than stylistic option, hence the pixel. Echewing rect border leaves a Pixel with no stylistic options to choose.
pixel_ :: Pixel -> Chart b Source #
A pixel is a rectangle with a color.
let opt = def {textColor=withOpacity black 0.8, textSize = 0.2} text_ opt "I'm a pixel!" <> pixel_ (Pixel one ublue)
pixels :: Traversable f => f Pixel -> Chart b Source #
Render multiple pixels
pixels $ [Pixel (Rect (5*x) (5*x+0.1) (sin (10*x)) (sin (10*x) + 0.1)) (dissolve (2*x) ublue) | x <- grid OuterPos (Range 0 1) 100]
pixelChart :: Traversable f => Aspect -> Rect Double -> [f Pixel] -> Chart b Source #
A chart of pixels
pixelChart_ :: Traversable f => Aspect -> [f Pixel] -> Chart b Source #
A chart of pixels scaled to its own range
pixelChart_Example :: Chart b pixelChart_Example = pixelChart_ asquare [ (\(r,c) -> Pixel r (blend c (rybColor 14 `withOpacity` 1) (ucolor 0.8 0.8 0.8 0.3))) <$> rectF (\(Pair x y) -> 4*(x*x+y*y)) one (Pair 40 40) ]
data PixelationOptions Source #
Options to pixelate a Rect using a function
