Graphics.Rendering.Chart.Layout

Description

This module glues together axes and plots to actually create a renderable for a chart.

Note that template haskell is used to derive accessor functions (see Data.Accessor) for each field of the following data types:

Layout1
LayoutAxis

These accessors are not shown in this API documentation. They have the same name as the field, but with the trailing underscore dropped. Hence for data field f_::F in type D, they have type

   f :: Data.Accessor.Accessor D F

Synopsis

Documentation

data Layout1 x y Source

A Layout1 value is a single plot area, with optional: axes on each of the 4 sides; title at the top; legend at the bottom. It's parameterised by the types of values to be plotted on the horizonal and vertical axes.

Fields laxis_title_style_ :: CairoFontStyle laxis_title_ :: String laxis_style_ :: AxisStyle laxis_data_ :: MAxisFn x laxis_reverse_ :: Bool True if left to right (bottom to top) is to show descending values

type MAxisFn t = [t] -> Maybe (AxisData t)Source

A MAxisFn is a function that generates an (optional) axis given the points plotted against that axis.

defaultLayout1 :: (PlotValue x, PlotValue y) => Layout1 x ySource

mAxis :: PlotValue t => AxisFn t -> MAxisFn tSource

Create an axis when there are points to be plotted against it.

noAxis :: PlotValue t => LayoutAxis tSource

Never create an axis

updateAllAxesStyles :: (AxisStyle -> AxisStyle) -> Layout1 x y -> Layout1 x ySource

Helper to update all axis styles on a Layout1 simultaneously

updateXAxesData :: (MAxisFn x -> MAxisFn x) -> Layout1 x y -> Layout1 x ySource

Helper to update data member of both horizontal axes in a Layout1

updateYAxesData :: (MAxisFn y -> MAxisFn y) -> Layout1 x y -> Layout1 x ySource

Helper to update data member of both vertical axes in a Layout1
