i need to write a chart that deals with a large number of datapoints collected on a device, more then a million after after a year. For that i am writing a dynamic fetching mechanismus that gets more detailed data after zooming. Is there a way to get the current start and end date of a rendered chart ? (The Values on X-Axis are Dates)
I found the “intervalStartPosition”, which would be close to the “enddate”, far right axis point, however i dont see a value with contains the other end.
Also you can go through rangeChanged and rangeChanging events which are triggered after/before viewportMinimum or viewPortMaximum are updated while zooming, panning, or reset.
