Hi Sathishkumar,
Thank you for using Syncfusion products.
You can display the scaling for some set of points by changing the secondary Y-axis's location and size. Please refer to the following code snippet.
protected void SetAxes()
{
axis1.LocationType = ChartAxisLocationType.Set;
axis1.Location = new PointF(this.chartControl1.PrimaryXAxis.Location.X, this.chartControl1.ChartArea.GetPointByValue(new ChartPoint(0, this.axis1.Range.Min)).Y);
axis1.AutoSize = false;
axis1.Size =new SizeF(0,(this.chartControl1.ChartArea.GetPointByValue( new ChartPoint(0 ,this.axis1.Range.Min )).Y
-this.chartControl1.ChartArea.GetPointByValue( new ChartPoint(0 ,axis1.Range.Max )).Y));
this.chartControl1.Redraw(true);
}
In our sample you can see secondary Y-axis scale place between 600 and 700 values of Primary Y-axis
Please have a look at this sample and let me know if this helps you.
