Thank you Yeray. That worked perfectly. Much appreciate -- both your explanation and timely reply.

I now know to look at the .SetNull functionality. Before your reply, I was thinking it would be something like a 'hidden' attribute, but now I now that wasn't the way to go.

Best,

Is there a way to hide one or more points in a series. For instance, let's say I have 4 series of 12 points each. Can I have a chart that show only points 1 thru 3 for the 1st series, 4 thru 6 for the 2nd, etc. If there's a functionality or property that controls this please advise. Thanks in advanc...
