Additional functions to help in generating the graphs.

Definition

minMax : Axes -> List ( Float, Float ) -> ( Float, Float )

Returns the min and max value for the given Axis. An empty list will return (0,0)

type Axes

= X

| Y

Describes which axes on the graph or from the data to use.

step : Step -> List ( Float, Float ) -> List ( Float, Float )

step modifies the input data so it will be drawn with a step on the Y axis.

type Step

= Before

| After

Defines where the step will occur

intersect : Axes -> Float -> List ( Float, Float ) -> Maybe ( Float, Float )

Attempt to find a point where a given value intersects with a dataset along either the X or Y axis.

This function is not optimized.
