Description

Bar Charts

Synopsis

Documentation

data PlotBars x y Source

Value describing how to plot a set of bars. Note that the input data is typed [(x,[y])], ie for each x value we plot several y values. Typically the size of each [y] list would be the same.

Constructors

PlotBars

Fields

_plot_bars_style :: PlotBarsStyle: This value specifies whether each value from [y] should be shown beside or above the previous value.
_plot_bars_item_styles :: [(FillStyle, Maybe LineStyle)]: The style in which to draw each element of [y]. A fill style is required, and if a linestyle is given, each bar will be outlined.
_plot_bars_titles :: [String]: The title of each element of [y]. These will be shown in the legend.
_plot_bars_spacing :: PlotBarsSpacing: This value controls how the widths of the bars are calculated. Either the widths of the bars, or the gaps between them can be fixed.
_plot_bars_alignment :: PlotBarsAlignment: This value controls how bars for a fixed x are aligned with respect to the device coordinate corresponding to x.
_plot_bars_reference :: y: The starting level for the chart (normally 0).
_plot_bars_singleton_width :: Double
_plot_bars_values :: [(x, [y])]: The actual points to be plotted.

Instances

BarsPlotValue y => Default (PlotBars x y)

data PlotBarsStyle Source

Constructors

BarsStacked	Bars for a fixed x are stacked vertically on top of each other.
BarsClustered	Bars for a fixed x are put horizontally beside each other.

Instances

Show PlotBarsStyle

data PlotBarsSpacing Source

Constructors

BarsFixWidth Double	All bars have the same width in pixels.
BarsFixGap Double Double	(BarsFixGap g mw) means make the gaps between the bars equal to g, but with a minimum bar width of mw

Instances

Show PlotBarsSpacing

data PlotBarsAlignment Source

How bars for a given (x,[y]) are aligned with respect to screen coordinate corresponding to x (deviceX).

Constructors

BarsLeft	The left edge of bars is at deviceX
BarsCentered	Bars are centered around deviceX
BarsRight	The right edge of bars is at deviceX

Instances
