Re: tikzplot displacement result

Hi Jan-Erik,

Use the \addplot command when you use pgfplots. The manual, pgfplots.pdf, is quite good.

\setupbodyfont[10pt]
\enableregime[utf]
\usemodule[tikz]
\usemodule[pgfplots]
\usetikzlibrary[arrows]
\setuppagenumbering[location=]
\starttext
\definecolor[ffvvqq][r=1.,g=0.3333333333333333,b=0.]
\startTEXpage
\starttikzpicture[line cap=round,line join=round,>=triangle 45,x=1.0cm,y=1.0cm]
\startaxis
[
x=1.0cm,y=1.0cm,
axis lines=middle,
ymajorgrids=true,
xmajorgrids=true,
xmin=-3.2488079448294145,
xmax=34.87398305791419,
ymin=-7.496155590728956,
ymax=11.53265632858922,
xtick={-3.0,-2.0,...,34.0},
ytick={-7.0,-6.0,...,11.0},]
%\clip(-3.2488079448294145,-7.496155590728956) rectangle (34.87398305791419,11.53265632858922);
\addplot[line width=2.pt,color=ffvvqq,smooth,samples=100,domain=-3.2488079448294145:34.87398305791419]{x+3} node[below right, pos= 0.1]{$h$};
\stopaxis
\stoptikzpicture
\stopTEXpage
\stoptext

I removed the clip command because it is causing a problem and is unnecessary. I don’t know what you are trying to do with the node{$h$}, but I made it a label on the plot.

The metafun graph module would also work for this plot, but it pgfplots is more mature. I recommend using pgfplots unless you are already skilled with metapost.

Hope that gets you going in the right direction.

Gavin
