|
|
* Added: Ticks display transformations
|

|
|
* - TickAdd: allow to add a fixed value to the graduations:
|

|
|
* usage: transform K = °C + 273,15, or °F = 1,8°C + 32 K = (°F + 459,67) / 1,8
|
|||
|
|
* - TickDivide: allow to diveide by a fixed value the graduations
|
|||
|
|
* usage: divide by 1000 => display graduations in kilograms when in gram
|
