Combination chart error

[goss]

Hi all,
I have a combination chart with 2 series
The first series is an area chart and diaplays correctly; dispalys
patrom counts by week

The second sereies is a column chart
Displays sales by week
When I added, plotted off to the right by week so no column on the
first data point and the last column is displaying only half a column

How can I fix this?

Thanks
