Description

Vector plots

Documentation

data PlotVectors x y Source

Constructors

PlotVectors 

Fields

_plot_vectors_title :: String
 
_plot_vectors_style :: VectorStyle
 
_plot_vectors_scale :: Double

Set to 1 (default) to normalize the length of vectors to a space between them (so that the vectors never overlap on the graph). Set to 0 to disable any scaling. Values in between 0 and 1 are also permitted to adjust scaling.

_plot_vectors_grid :: [(x, y)]

Provide a square-tiled regular grid.

_plot_vectors_mapf :: (x, y) -> (x, y)

Provide a vector field (R^2 -> R^2) function.

_plot_vectors_values :: [((x, y), (x, y))]

Provide a prepared list of (start,vector) pairs.
