All series data points in a chart control share one DateTime pool.

Simple example

void Main()
{
    LineSerie serie1 = new LineSerie
    {
        ID = Guid.NewGuid(),
        Name = $"Serie1",
        Color = Color.Red,
        StrokeSize = 2f,
        SharedScaleID = 1,

    LineSerie serie2 = new LineSerie

        ID = Guid.NewGuid(),
        Name = $"Serie2",
        Color = Color.Blue,
        StrokeSize = 2f,
        SharedScaleID = 3,
    };

    LineSerie serie3 = new LineSerie
    {
        ID = Guid.NewGuid(),
        Name = $"Serie3",
        Color = Color.Green,
        StrokeSize = 2f,
        SharedScaleID = 3,
    };

    // SharedScaleID will force auto scale to use matching id series cluster 
    // min and max for new scaling values,
    // keeping the YMin and YMax values across them equal.
    // In this case, serie1 is independent and both serie2 and serie3 are linked.
    // 0 = Disabled.

    ikLineChart.IkAddSerie(serie1);
    ikLineChart.IkAddSerie(serie2);
    ikLineChart.IkAddSerie(serie3);

    // Feed the simulated values for each available serie,
    // Caller controls chart update rate.
    // If not all series are present in the update package, 
    // the last available value for that serie
    // will be used or a 0 if its empty.
    // If you don't have a new value for a given serie, 
    // use double.NaN in order to append the latest data point available or a 0.
