Indicates whether or not trend plots should be drawn using a logarithmic scale.
If set to 0 (default), then trend plots are not converted to a logarithmic scale.
If set to 1, trend plots for both live and historical data are converted to Log base 10. (All trends are shown on a log scale with the mid-scale value reading being derived from the equation Pow(10, (Log(ScaleHi) + Log(Scalelo)) /2)).
Default: TrendLogarithmicScale = 0
