Hi,
ok, I see the issue.
One other thing. I get tons of messages like
NOTE: coordinate (0.6,0.1) has been dropped because it is unbounded (in x).
(see also unbounded coords=jump).
I added filter discard warning=false, so the log output is not cluttered so
much:
\pgfplotsset{
only if/.style 2 args={
filter discard warning=false,
x filter/.append code={
\edef\tempa{\thisrow{#1}}
\edef\tempb{#2}
\ifx\tempa\tempb
\else
\def\pgfmathresult{NaN}
\fi
},
},
}
(so this message was less of a question, more of documentation)
Best Regards,
Florian
