Hi,
Thanks for choosing Syncfusion products.
You can initialize the Custom Y-Axis to multiple chart series by using the following lines of code.
C#:
//Initialize Speed Y-Axis. This is Custom Y-Axis Will be initializing Chart series.
ChartAxis Speed = new ChartAxis();
Speed.Header = "Speed";
Speed.Orientation = Orientation.Vertical;
Speed.OpposedPosition = true;
//Initialize the second chart series with Y-Axis as Speed.
ChartSeries series2 = new ChartSeries();
series2.Data = converter.ConvertFromString("1,50,2,70,3,80,4,40,6,50") as ChartListData;
series2.YAxis = Speed;
//Initialize the third chart series with Y-Axis as Speed.
ChartSeries series3 = new ChartSeries();
series3.Data = converter.ConvertFromString("1,85,2,100,3,50,4,70,6,90") as ChartListData;
series3.YAxis = Speed;
