Can you kindly create a JSFiddle reproducing the issue and share it with us so that we can look into the code, understand the scenario better and help you out?
Hi,
here is my JS FIDDLE: https://jsfiddle.net/m9sf6awn/
as you can see the markers near to the x/y axis are not displaying completely and it doesnt looks good when i have to display a large number of data
thanks
