Question : SSRS 2008 - Line with Markers Chart - Missing Lines

I have a Line with Markers chart that has multiple related series in it. The chart seems to accurately display the marker points, but only draws about half of the lines that connect the points in any given series.

If the chart only shows one series it displays fine. It's when I include multiple series that the lines are incomplete. Additionally, it seems that the more series I add, the less complete the lines.

Any ideas whats wrong?

Specifics... The chart represents the amount of a given chemical detected at various spots/locations in a landfill. So its a numerical result, by location over time. Charting one location works great. If I add a second location, all the Markers are displayed, but a couple lines that connect them are missing. If I add a third location, all the Markers are displayed, but even more lines are missing.

You are correct about setting the EmptyPointValue to avarage

In the Properties pane, expand the CustomAttributes node

Set the EmptyPointValue property. To insert empty points at an average of the previous and next data points, select Average. To insert empty points at zero, select Zero.
