Graphics.Rendering.Plot.Figure

Creation and manipulation of Figures

The same problem of leaked instances as at http://hackage.haskell.org/packages/archive/graphviz/2999.10.0.1/doc/html/Data-GraphViz-Commands.html#t%3AGraphvizCanvas occurs here.

with, set, clear, new, and add are the operations that can be performed on various elements of a figure.

glib/data-accessor abstractions (verbs/modifiers) are planned for future implementations

candle :: (Ordinate a, BarFormat b) => a -> b -> FormattedSeries

whisker :: (Ordinate a, BarFormat b) => a -> b -> FormattedSeries

setDataset :: Dataset a => a -> Plot ()

set the data series of the subplot

The data series are either FormattedSeries or plain data series. A plain data series must carry a SeriesType.

A dataset may or may not have an abscissa series, and if so, it is paired with either a list of ordinate series or a single ordinate series.

The abscissa series (if present) is of type 'Vector Double'.

An ordinate series be a function (Double -> Double) or a series of points, a 'Vector Double' with optional error series, y axis preference, and labels.

To specify decoration options for an ordinate series, use the appropriate function, such as linespoints, with the ordinate series and decoration formatting (LineFormat, PointFormat, and BarFormat) as arguments.

setDataset (ts,[linespoints (xs,(le,ue),Upper,"data") (([Dash,Dash],3,blue),(Diamond,green))])

has abscissa ts paired with a list of ordinate series, the single element of which is a FormattedSeries, linespoints where the ordinate is xs with error series le and ue, to be graphed against the upper y-range with label "data". The line element is formatted to be dashed, of width 3, and blue and the point element is to be a green diamond.

withSeriesFormat :: PlotFormats m => Int -> m () -> Plot ()

withAllSeriesFormats :: PlotFormats m => (Int -> m ()) -> Plot ()

the operation to modify the formats is passed the series index. This allows, for example, colours to be selected from a list that gets indexed by the argument

setColour = withAllSeriesFormats (\i -> do
                                        setLineColour $ [black,blue,red,green,yellow] !! i
