Hi Yi & team, Many thanks for replying.
So can we keep showing set of data on the graph depending on specific time window? I meant last 1 hour of data. The window will slide every 30 seconds on the time axis. example. Example - 1 - Browser opens and fetches data points from backend of last 1 hour. *8:00AM-9:00AM*. It graph plots 50 data points as bars. 2 - Now UI will fetch the new records every 30 seconds using *setInterval* function. Now at 9:00:30 it gets another 5 records from backend. 3 - Now the window on the graph should show all data points between *8:00:30 and 9:00:30* Is the above achievable in e-charts?
