Hi Tang

Please see our article Value Axis vs CategoryAxis which explains the difference.

Category Axis: X -values are ignored. Index of data is used to calculate the spacing

Value Axis: X-values contribute to spacing of drawn points

For example. CategoryDateTimeAxis is used in financial trading systems to remove gaps for weekends / overnight.

Best regards,
