Hi Alok,
1. Yes. It is possible to display the secondary axis side-by-side by using location property.
2. To set the location of the axis correctly during resize please try setting the location in the LayoutCompleted event which will be raised after the chart has completed laying out of Primary axes.
Kindly have a look at the attached sample which illustrates the above.

3. I am afraid that I was not able to reproduce the issue that you have raised here. I have tested this condition with a small sample and the application works fine. If possible please modify the sample attached which help us to reproduce the issue so that it will be easier for us to find out the cause for the problem.

4. You can set the Format property of the ChartAxis class to display decimal values upto one point. The following code snippet illustrates this:
this.chartControl1.PrimaryYAxis.Format = "#.#";
Kindly let me know if this helps you.
Thanks for your interest in Syncfusion products.
Regards,
Geetha.
