legend.mode seriesComapre is not working in Splunk JS Stack

[thuhuongle]

Hi,
I try to test a simple chart option "charting.legend.mode": "seriesCompare" via ChartView components of the Splunk Web Framework . I want the legend display/compare all  differences point values of 4 lines as we move alongs the line.  Is this a limite of ChartView or i am missing something here?
thanks for your time!!!

able to do in Splunk Entreprise only:

g.highcharts legend not able to display difference point values. Seem like, option standard is the only avaiable option.
