Continuous data in line chart

Continuous data in line chart

Love the new version of charts, but there's one issue that is problematic for me.  In the prior version, the smooth line chart would maintain a continuous line along a date axis, even if there was missing data for a given period.  This is not true in the new version.  

The use case is that I want to show actual sales vs. weekly sales targets (straight-lined) across the year.  So, if you're in the 6th week of the fiscal year, you want to see just the first six weeks of sales but the full 52 weeks of sales targets.  

How are others setting up their data to see something like this with the new charting tools?
