I am trying to display daily production data on a line chart in pounds of product produced per hour.  We have 2 departments that appear on this chart however, some days 1 of the 2 departments may not be scheduled for production.  On these days in my chart, I don't want to show a zero value for pounds per hour because it shows as a sharp dip in productivity.  I need the line chart to skip that day for the zero value.

Can anyone shed some light on how I can accomplish this?

My datasource is a datatable with decimal values for the points on the line.

Thanks in advance for your help,
