Per implementare di una scalatura personalizzata da applicare al valore di una variabile, e’ necessario implementare l’interfaccia “IToolS.Data.IValueScale”, ad esempio:
|
1 2 3 4 5 6 7 8 9 10 11 |
class MyScaling : IToolS.Data.IValueScale { public object Scale(IVariableInternal variable, object value) { return Convert.ToInt32(value) * 2; } public object Unscale(IVariableInternal variable, object value) { return Convert.ToInt32(value) / 2; } } |
Quindi impostare la classe di scalatura implementata alla variabile:
|
1 |
m_variable1.SetValueScale(new MyScaling()); |
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 |
