Re: [Gnuplot-info] Plotting 3-dimensional tree

[Thomas S. <t.s...@fz...>]

splot 'datafilename' with lines

should work, but let one data block (separated by one blank line) have more
than two points otherwise you will get cross isolines.

to have branches in different colors you should divide your data into
data sets (separated by double blank lines) and use the 'index' option
of the 'splot' command.
