A framework for creating 2D charts in Haskell.
For the simplest API, see the Graphics.Rendering.Chart.Easy module.
When more control is required, understanding the various data types
is necessary. The basic model is that you define a value
representing a chart to be displayed (eg. a Layout
), and then
convert it to a Renderable
by applying toRenderable
. This
Renderable
is then actually output by calling a function in an
appropriate graphics backend, eg renderableToFile
.
Currently, there are three types of charts:
Layout
is a standard XY chartLayoutLR
is an XY chart with independent left and right axesPieLayout
is a pie chart
Layout
and LayoutLR
charts can be stacked vertically using
the StackedLayouts
type.
Renderable
s can be composed in arbitrary ways using the
Graphics.Rendering.Chart.Grid module.
Many of the record structure involved in the API have a large
number of fields. Lens
es are provided to access each field. Also,
for each record type, there is generally a default value, which can
be accessed through the def
value of the Default
typeclass.
