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.
Best Regards,
