Martin:
I have seen a strange problem which may or may not be related.
It is actually an opposite of yours. The line is not drawn on screen,
but it is printed. The problem is located somewhere in f.DrawPath.
You mentioned DrawPath, what triggered my response.
I have not narrowed down the problem with a short example which
I can post, so let me just describe when (I think) it can happen.
In case the line width is set to 0, i.e., a hair-line, and the
path is partly outside the frame, such that some segments are clipped,
the path is not plotted on screen at all. As soon as the width
is at least two pixels, clipping works and the path is plotted.
This only happens on screen. I have not seen any cases yet
where the printout would be incomplete.
I am reporting this for the record. Maybe it is related.

and I just did a plot where it looks fine on the screen,
and it also looks fine if I copy and paste it into Powerpoint
(as an enhanced metafile). A printout from Powerpoint
of this plot also looks fine.

the printout has about half of the data points missing
(the latter half). This particular plot is rather complex,
and probably makes a few thousand calls to f.DrawOval
and also a lot of calls to f.DrawPath.

I'm wondering if this is something that I've programmed wrong,
or if there's a bug/limitation in Blackbox's printing capability.
