PlotKit Base

PlotKit Base contains a number of simple functions that are needed for the rest of the PlotKit libraries.

PlotKit.Base Functions

Returns the X value of the element relative to the document in a browser independent way.

Returns the Y value of the element relative to the document in a browser independent way.

• palette(baseColor, fromLevel = -0.2, toLevel = 0.2, increment = 0.1)

Takes in a base colour and generates a palette of colours based on the intensive levels.

• roundInterval(value, precision)

Rounds a number to a specified precision. TODO: make more robust
