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

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

format the plot elements of a given series

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
