[libreoffice-users] Help formatting Calc chart

I have a spreadsheet tracking some information by date. The rows are 
sparse, that is, some dates are missing. When Calc produces the chart, 
it seems to assume that each row is equidistant. The distance between 
7-7-12 and 7-9-12 is the same as the distance between 3-2-12 and 
5-16-12. There are many missing data points between the latter two dates.

How can I get the chart to be intelligently formatted such that missing 
data points for dates are given appropriate space? I do have the date 
column formatted as Date.

And, no, I do not want to add rows for the missing dates.

Thank you,
Chuck
