[Gnuplot-bugs] error in script

[Piotr B. <pb...@um...>]

Hello,

I use gnuplot quite often to plot data output from computer simulations.  I usually make scripts to save time on making a batch of plots.  I think I may have found a bug when trying to multiply the data.  When trying to multiply the values in column 2 by 2, for example

plot 'file.dat' using 1:($2)*2

this will work when running the plot command from the gnuplot terminal... but it seems to have problems when calling a script with exactly the same lines.  It gives values of zero.  I've double checked this on the most recent version 4.4 of gnuplot.

Cheers,
Piotr
