[Tex/LaTex] Markers (xtick) in PGFplots with higher precision

pgfplotstikz-pgf

Graphic

The following MWE shows a figure with all identical axis markers (because the scale is too narrow). The option xtick has not "high enough precision".

MWE Code

I did not find a suiting example in the pgfplots package manual – maybe I did not read/think long enough…
I am not sure what option should be entered in the axis environment.

\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=newest}

\begin{document}
\begin{tikzpicture}
\begin{axis}[every minor tick]
\addplot coordinates{(0.999,2e-2) (1.001,12) };
\end{axis}
\end{tikzpicture}

\end{document}

Based on Umz's comment, the following code solves the problem.

\documentclass[margin=2mm]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=newest}

\begin{document}
\begin{tikzpicture}
\begin{axis}[every minor tick,
  x tick label style={
    /pgf/number format/.cd,
    fixed,
    fixed zerofill,
    precision=4
  }]
\addplot coordinates{(0.999,2e-2) (1.001,12) };
\end{axis}
\end{tikzpicture}

\end{document}

[Tex/LaTex] plotting two time series with bounds

This happens because PGFPlots only uses one "stack" per axis: You're stacking the second confidence interval on top of the first. The easiest way to fix this is probably to use the approach described in "Is there an easy way of using line thickness as error indicator in a plot?": After plotting the first confidence interval, stack the upper bound on top again, using stack dir=minus. That way, the stack will be reset to zero, and you can draw the second confidence interval in the same fashion as the first:

[Tex/LaTex] pgfplots markers and lines on different layers

You can set clip mode=individual: That way, the plot markers are placed directly on top of their respective lines, and later plots are drawn on top of earlier plots:
