Method Detail

precalc

void precalc()

Force a precalculation of the variables required for the pixel transformation.

calculatePosition

For a given coordinate in the units of the data, will calculate the render coordinates

Parameters:

units - The unit to convert to render coordinates

Returns:

Render coordinates

calculateUnitsAt

D calculateUnitsAt(U position)

Calculates the data unit coordinate at the given render coordinates

Parameters:

position - The data rendered position to convert

Returns:

the data units on the given axis

scaleDimension

U scaleDimension(D dimension)

Given a specific data dimension, calculates a render dimension.

Parameters:

dimension - The units/data dimension

Returns:

The scaled dimension
