I modified in grapher.pm ploticus_arg("-maxrows", "20000") to
ploticus_arg("-maxrows", "40000") and the problem continue (only with Source
I added "2>/tmp/ploticus.stderr" in ploticus.pm and I see the following in
the ploticus.stderr file:
pl proc getdata: error 406: Data input truncated... too many data fields
(try raising -maxfields)
cat: stdout: Broken pipe
I don't Know where put the -maxfields argument and its value. Can you help

Its a good possibility that ploticus is complaining about too
much data (but we don't see it because its stderr is lost).
In grapher.pm you'll find this line:
you might try doubing that. Note however that ploticus has other
default limits that might be a factor.
To debug more in ploticus.pm find the function ploticus_begin and
then add something like "2>/tmp/ploticus.stderr" to the end of the
$cmd that gets spawned.
