Re: Conditional plotting
a few questions:
- if you plot the 5 lines of data you posted recently,
do you get the same plot result as i did?
No, I don't. I still get just the candlesticks with one line plotted at the zero level and the other line is missing completely.

- how large is your data file?
the data file(s) are 3000+ lines
- the gnuplot program - is it from the distribution or
did you compile it from source?
It is from the distribution repositories, installed via Synaptic. The installed packages are gnuplot 4.2.4-6, gnuplot-x11 4.2.4-6, gnuplot-doc 4.2.4-6 and gnuplot-nox 4.2.4-6.
