// Two GM Series.
Series gms = new Series("GM (Covette)");

// In order for the gm series to be stacked we need a new axis with a stacked scale.
gms.YAxis = new Axis();
gms.YAxis.Scale = Scale.Stacked;

// Use the same axis for both series.

// Ensure scales match
gms.YAxis.Maximum = 7000;

// Make the new axis invisible.

// Add the data.
