EPPlus - Scatter chart - Draw a secondary Y-Axis

Question

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 second 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) -( https://stackoverflow.com/questions/28540458/using-secondary-axis-for-chart-cause-x-axis-and-primary-y-axis-issue-excel)

 

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
