Subrange of data points and labels


Is it possible to place labels and points on a subset of a line series?  To balance performance and clutter, I calculate what the zoom range is to decide whether or not to showPoints and showLabels. I’ve three series and in long acquisitions when I go to zoom in, all point labels are enabled which bogs down the refresh rate – I’d ultimately like to enable only the points and labels in view for whatever tever zoom factor[range] is on the screen…any insight would be much appreciated.
