[paparshoot]

hi, i need the viewport minimum and maximum when line chart zoomed by the user, how can i find or calculate these amounts?
when user manually zoom the line chart and select the scope, i need the start point and end point that selected by user?

@paparshoot,

This can be achieved using rangeChanged event handler.

Please take a look at this JSFiddle
