Hi Robert,
It is possible to use single label for a group of points by using GroupingLabels.
I have given the sample in the below link.
Sample Link:
http://files.syncfusion.com/support/Chart.Windows/v7.3.0.20/F89663/F89663/main.htmUse ChartControl1.PrimaryXAxis.DateTimeRange property to control the range of Axis. If this is assigned to some value,
then it will decide the start, end , interval value of the axis.
Please let me know if this meets your requirement, otherwise provide us your output screenshot and clear details about
your requirement.
Regards,
Venkat.
