How to make the TikZ option raw output aware of segments
As my previous post suggested, I was tweaking the
pgfplots code a little, to produce a nice algebraic curve from
gnuplot data. The current behaviour just connects all the dots in the automatically produced
.table file. But as the calculation of an implicit function in
gnuplot involves the creation of a surface and intersecting it with the z=0 plane, the output is not as good as it would be in the case of a regular function.
But, I've hacked together a solution! Just replace the definition of
It actually went quite smooth, it took me less than an hour to start reading the source (after a tip on tex.stackexchange.com) to find the solution, write an answer for my topic and write two blog posts about it.
By the way, the code to produce the plot is
So in case you've always wondered how to draw algebraic curves or implicit functions in LaTeX, this is my hackish solution! Any comments on this?
