computeScaleHeightOfValue
static float computeScaleHeightOfValue(double value, double oneUnitPixelSize)
Takes a value and determines the number of pixels it should fill on the screen. If there is a user defined scale and the passed value is greater than the MAX or less than the MIN, the height will be forced to the MAX or MIN respectively.- Parameters:
value
-oneUnitPixelSize
-- Returns:
- float the screen pixel coordinate
