Oscilloscope class

A widget that defines a customisable Oscilloscope type display that can be used to graph out data

The dataSet arguments MUST be a List

All other arguments are optional as they have preset values

showYAxis this will display a line along the yAxisat 0 if the value is set to true (default is false) yAxisColor determines the color of the displayed yAxis (default value is Colors.white)

yAxisMin and yAxisMax although optional should be set to reflect the data that is supplied in dataSet. These values should be set to the min and max values in the supplied dataSet.

For example if the max value in the data set is 2.5 and the min is -3.25 then you should set yAxisMin = -3.25 and yAxisMax = 2.5 This allows the oscilloscope display to scale the generated graph correctly.

You can modify the background color of the oscilloscope with the backgroundColor argument and the color of the trace with traceColor

The margin argument allows space to be set around the display (this defaults to EdgeInsets.all(10.0) if not specified)

The strokeWidth argument defines how wide to make lines drawn (this defaults to 2.0 if not specified).

NB: This is not a Time Domain trace, the update frequency of the supplied dataSet determines the trace speed.
