getCoordinate
public double getCoordinate(int index) Returns the coordinates of specified ticks. For the sake of performance, invokers need to ensure the index correct.- Parameters:
index
- tick index- Returns:
-
getTickSlot
public int getTickSlot(double value) -
getNormalizedCoordinate
public double getNormalizedCoordinate(int index) Returns the normalized tick coordinates. that means the start point is always zero, and the array lines forward. For the sake of performance, invokers need to ensure the index correct.- Parameters:
index
- tick index- Returns:
-
