// MultipleY:

// To plot mutliple Y variables by the same X variable, add the 
// Y variables to a PlotVariableList, and then assign the Y role
// to that list rather than to an individual variable.
//
// Optionally, you can modify the Y axis and specify labels.
// This sample also disables markers and enables plot interpolation.
