@mitul013,
when i created stackedbar/stackedcoloumn chart with many bars(data) then it shows alternate lable how i overcome this issue
Alternate labels are skipped to avoid overlapping of labels, which can be customized to show all the labels by setting the interval property to the desired value.
second point is when use stackbar that time how use scroll for too many data(bars)
Can you kindly create and share a JSFiddle and brief us further about your requirement so that we can understand your scenario better and help you out with an appropriate solution.
