In trying to pin down the previous issue, I managed to reproduce another
bug that has been bugging me for some time that I was never able to pin
some times, when scrolling or zooming, parts or all of the plotted line
fail to render (on wxt, not tested elsewhere)
gnuplot> !cat "fx_test.dat"
plot "fx_test.dat" w l , f(x)
one scroll up looses the left leg of the plot line. Scolling back it
returns and two or more events is fine. Just the one position is
affected and is repeatable once it happens.
On starting again the same plan did not reproduce it so another factor
also must be involved. I mention it anyway because this is a long
I similar zoom problem is that certain zoom selections can result in
nothing getting plotted.
I usually have to fiddle around to find a similar zoom selection a bit
larger that does render correctly.
I suspect these two defects have the same root cause.
