I managed to get around the problem by adding a new row that contained the
TEXT() values of the cells containing the dates and used this row as the
x-axis instead.
However, I would be interested to know if this "fill in the missing dates in
the series" effect is something that can be deactivated without having to go
this workaround.

Yes. The first time, you had dates that Excel recognised, and it
automatically selected "Time-scale" for the X axis. The second time, you
gave the X axis data as words that Excel cold not recognise as dates,
and it chose "Category" for the X axis.

If you go to the menu...

Chart.. Chart Options.. Axes

...you can switch the X axis from "Automatic" (Excel chooses) to
"Category" or "Time-scale" (you choose). You want to choose "Category",
and then the X axis will work the way you want even if the cells are
clearly dates.

Typical of Microsoft to hide important axis controls in a separate
"Chart Options" section instead of the logical "Format Axis" section
that everybody knows about, so that nobody knows what's going on when
this happens, or how to fix it. And of course they're too cheap for
manuals, which should make them even more careful to design their
product logically, not less.
