My Requirement
I need to draw a second Y-Axis on a Scatter chart using C#.

My data pattern
Signal-1 Value
Signal-2 Value
Time Received.

Expected Chart
I need to draw the chart to have
Signal-1 value on the X-Axis
Signal-2 value on the Y-Axis
Time Received on the second Y-Axis.
Please let me know how to draw the secong Y-Axis to represent the time value.
I have searched in net, but the solution I get for having Y-Axis is to plot a another series -
Using secondary axis for chart cause x-axis and primary y-axis issue (Excel)

What I have tried:

My Current Code
var scatterChart =
workSheet.Drawings.AddChart("scatterChart", eChartType.XYScatterLines) as ExcelScatterChart;
scatterChart.Title.Text = GraphTitle;
var rangeLabel = workSheet.Cells["D2:D2571"];
var range1 = workSheet.Cells["C2:C2571"];
scatterChart.Series.Add(range1, rangeLabel);
scatterChart.Series[0].Header = workSheet.Cells["A1"].Value.ToString();
scatterChart.Legend.Position = eLegendPosition.Right;
scatterChart.SetSize(600, 300);
scatterChart.SetPosition(5, 0, 1, 0
