How can I plot data points with pgfplots that have no marks, but error bars? If I try marks=none
and enable errobars, I get big filled circles with errobars. If I change my mark to mark=+
, for example, I have to adjust the mark size by hand, so that the errorbars are bigger than the mark.
The reason is, if I have error bars, I automatically have the actual data point: the point where the error bars cross. So I don't need an explicit mark , but as described, just setting mark=none
doesn't seem to be enough to achieve this.
This plots filled circles with error bars as marks even mark=none
is set:
\begin{tikzpicture}
\begin{axis}
\addplot[ only marks, mark=none,
error bars/.cd, y dir=both, x dir=both, x explicit, y explicit]
table [x index=0, y index=2, x error index=1, y error index=3]
{mydata.txt};
\end{axis}
\end{tikzpicture}
Part of the content of mydata.txt
to work with:
3.414 8E-3 3.62 5E-2
1.570 2E-2 1.65 1E-1
3.809 9E-3 3.96 3E-2
4.340 2E-2 4.34 3E-2
How do I get error bars without an actual mark symbol, so that the point is "auto-marked" by the crossing of the error bars?
mydata.txt
? (filecontents
is a great environment if you're unaware ;)) – Sean Allred Mar 29 '13 at 13:08
