I am using TexLive XuaLatex with PGFplots 1.13 to plot data. I have a table like this:
x , y , z
0 , 0 , 0
0 , 0 , 1
1 , 1 , 0
1 , 1 , 1
2 , 2 , 0
2 , 4 , 1
3 , 3 , 0
3 , 9 , 1
4 , 4 , 0
4 , 16 , 1
5 , 5 , 0
5 , 25 , 1
6 , 6 , 0
6 , 36 , 1
How can I use the PGFplot axis-environment to plot y over x where z=bar, when bar is a number. I'm thinking kind of the way you can access data with MySQL
\begin{tikzpicture}
\begin{axis}[/pgf/number format/.cd, use comma]
\addplot
table[x=x,y=y,WHERE z=0, col sep=comma]
{DATA.csv};
\addplot
table[x=x,y=y,WHERE z=1,col sep=comma]
{DATA.csv};
\end{axis}
\end{tikzpicture}
I have not found anything on that in the guide. I do not want a solution that omits the question by having a table like that:
x, y1, y2
and then do plot with x=x, y=y1 and a second plot with x=x, y=y2.
This might be a handy solution for the simple example I am giving but it does not work for my problem, because in the real problem there are 10 different y to be plotted over x for 4 different z, and I really don't want the implementation like the solution proposed for several reasons.
Thank you very much for your time
x filter/.code
(or itsy/z
equivalent) yet? See here: tex.stackexchange.com/a/66192/131649 or the pgfplots manual section 4.22 (p.383f in v1.14).
