chart date data with x axis showing correct relative placement

I need to chart data so that I can accurately show date-dependent data along
the x-axis. I need the appropriate relative spacing along the xaxis to depict
varying intervals between data collection points, because my data is
collected sporadically. Also, where there are missing data points, I'd like a
line interpolated across missed dates. I often have several lines on one
chart, and often have each line based on data collected at different dates.
My initial charts appear to show gaps in the lines where they cross a date on
the xaxis for which they do not have data.
