Re: [Gnuplot-info] Managing long/complicated plot commands?

[hchiPer <hc...@gm...>]

I'm willing to test your plot command, but I can't because it is full of 
functions, parameters, script arguments and referenced files that you 
don't provide:
I get an 'undefined function: lon' error, not 'invalid character \'

I was only able to find world_110m.txt from this page: 
https://gnuplotting.org/tag/parametric/ (I presume it's the one you are 
using but I'm not sure).
