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.

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_ :: [(CairoFillStyle, Maybe CairoLineStyle)]: 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.
