Hi Sam,
Thanks for using Syncfusion products.
Labels will be enabled automatically based on the values of series points. When a series is added to the "ChartAdv" control, labels will be displayed in axis depending upon the axis range. By default, value of the first label in axis is the minimum value of axis range and last label value is the maximum value of axis range.
Please let us know if you have any concern.
Regards,
Anandaraj
