data RectOptions Source #
Just about everything on a chart is a rectangle.
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
rect_Example :: Double -> Chart b rect_Example n = labelled (opts (Pair n 1)) "z,w" $ labelled (opts (Pair n -1)) "z,y" $ labelled (opts (Pair (-n) 1)) "x,w" $ labelled (opts (Pair (-n) -1)) "x,y" $ rect_ def (Ranges (n *. one) one) where opts :: Pair Double -> LabelOptions opts o = #text %~ ( (#color .~ black `withOpacity` 0.8) . (#size .~ 0.3)) $ #orientation .~ o $ def
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 (rectBars 0 [1, 2, 3, 5, 8, 0, -2, 11, 2, 1])
rectChart :: Traversable f => [RectOptions] -> Rect Double -> Rect Double -> [f (Rect Double)] -> Chart b Source #
A chart of rects
rectChart_ :: Traversable f => [RectOptions] -> Rect Double -> [f (Rect Double)] -> Chart b Source #
A chart of rectangles scaled to its own range
ropts :: [RectOptions] ropts = [ #borderSize .~ 0 $ def , #borderSize .~ 0 $ #color .~ ucolor 0.3 0.3 0.3 0.2 $ def ] rss :: [[Rect Double]] rss = [ rectXY (\x -> exp (-(x ** 2) / 2)) (Range -5 5) 50 , rectXY (\x -> 0.5 * exp (-(x ** 2) / 8)) (Range -5 5) 50 ] rectChart_Example :: Chart b rectChart_Example = rectChart_ ropts widescreen rss
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.
pixel_Example :: Chart b pixel_Example = text_ opt "I'm a pixel!" <> pixel_ (Pixel one ublue) where opt = #color .~ withOpacity black 0.8 $ #size .~ 0.2 $ def
pixels :: Traversable f => f Pixel -> Chart b Source #
Render multiple pixels
pixelsExample :: Chart b pixelsExample = 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 => Rect Double -> Rect Double -> [f Pixel] -> Chart b Source #
A chart of pixels
pixelChart_ :: Traversable f => Rect Double -> [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 (ucolor 0.47 0.73 0.86 1) (ucolor 0.01 0.06 0.22 1) )) <$> rectF (\(Pair x y) -> (x+y)*(x+y)) one (Pair 40 40)]
data PixelationOptions Source #
Options to pixelate a Rect using a function
