Y = Y2 / factor - offset
Formula for converting Y to Y2:
Y2 = (Y + offset) * factor
Figure 7-2 Example with second Y axis with own scaling
Example
Y: 0 to 200 should correspond to Y2: -25 to 25.
● Offset: -100
● Factor: 0.25
Calculation example:
Y2 = -30
Y = -30 / 0.25 – (-100) = -20
Calculation example:
Y = 0
Y2 = (0 + (-100)) * 0.25 = -25
The X axis is the same for both coordinate systems.
You can set the colors using setForeColorY2() and setGridColorY2() (see colors).
The axes are labeled with setAxisNameY2() (see axis identifiers).
