Hi TC, thanks for answering.
I believe from what digging I did that the problem I'm encountering is
different and a bit more insidious than the one SPL gave an algorithmic fix
for.
I'm noticing incorrect answers from fl_get_xyplot() if arbitrary xmin/xmax's
are asked for. If the whole dataset is showing on the xyplot there's no
problem. If only a part is showing, a part where the start of the dataset is
offscreen, fl_get_xyplot returns nonsense.
In a slightly later posting, I gave a coded example (butchered from
activexyplot.c). It displays the problem I'm encountering in my large app.
John
