Hi Shweta,
You can apply a custom numeric value formatter:
   NLinearScaleConfigurator yScale = (NLinearScaleConfigurator)chart.Axis(StandardAxis.PrimaryY).ScaleConfigurator;
    yScale.LabelValueFormatter = new NNumericValueFormatter("00.");
The above for example will make sure the numbers always start with 2 digits. 
Let us know if you have any questions.
