DevExtreme Vue - Group Smaller Points
Smaller points on the PieChart can be collected in a single group in one of the following modes:
Top N
Top N points with the biggest values remain ungrouped; all other points form a group. The smallValuesGrouping.topCount option specifies the N.Threshold
Points that fall beyond a threshold establish a group. The smallValuesGrouping.threshold option specifies the threshold.
The group for small points is called "others" by default. You can change this using the smallValuesGrouping.groupName option.
