Feature Suggestion

Feature description:
I want to dynamically set a plot scale (i.e. multiply 'ys' by a specific number before rendering) for a Signal without modifying its raw data 'ys', but currently it seems there is no built-in method to make it.
Code example:

// a code sample may improve communication
var plt = new ScottPlot.Plot();
var signal = plt.AddSignal(dataY);
signal.OffsetY = 10.0;
signal.ScaleY = 5.0;
plt.Refresh();
