<number> output = <series>[<number> Index]
Use to index into the data series. Returns the value of the specified sample. Can be read or written. The index must be between zero and NumPoints - 1, inclusive if reading from the index. A series will grow dynamically to accommodate indexing when assigning a value to an index. There is no need to pre-define NumPoints.
Examples:
for(var i = 0; i < mySeries.NumPoints; i++)
mySeries[i] = i*2;
var sample5 = mySeries[5];
