// 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.
