Hi Shweta,

You can take a look at the following topic in the documentation:

http://helpdotnetvision.nevron.com/#UsersGuide_Axes_Scale_Scale_Labels.html
The "Label Layout Fit Modes" section talks about the different options you have to configure the label fit modes. You can also take a look at the All Examples\Axes\General\Axis labels example on how to apply different label non-overlapping settings. In this case, you probably need stagger and auto-scale label fit modes. You can also consider using label formatting with limited decimal precision to avoid excessively large labels.
We hope this helps – let us know if you have any questions or meet any problems.

Hello,
I am using Bar chart in which x- axis value is overlapping with each other.
I am setting x - axis value using setting Labels on scale like below lines of code.
I want to reduce ticks to readable x- axis value and avoid overlapping.
How can I autoscale labels on scale? 
Is any other way to set x-axis value in bar chart which provide autoscaling?
NStandardScaleConfigurator scale = (NStandardScaleConfigurator)this._cartesianChart.Axis(StandardAxis.PrimaryX).ScaleConfigurator;
scale.AutoLabels = false;
scale.Labels.Add("0");
scale.Labels.Add("4");
scale.Labels.Add("8");
