Hi Park,
Greetings from the team at Syncfusion. We have looked over your request and recommend that you use the axis
anchorRangeToVisiblePoints property. By default, the data source calculates the axis range, however, utilizing this property will cause the chart to keep the range about the auxiliary axis. We also suggest you use the
visibleMinimum and
visibleMaximum to maintain the range of the axis and please use the above solution concerning your requirement. Following help document will help you to know more about this.
Please revert us if you need any further assistance on this.
Thanks,
