# pgfplots: log ticks with fixed point on one logarithm axis

I have a graph with two logarithmic axes but I wish to set the labels of one of them to display in fixed point format. Is this possible? Below is a minimum example of how to get both axes using the fixed point format. I want the x axis to be fixed point.

\begin{figure}[H]
\centering
\begin{tikzpicture}
\begin{loglogaxis}[
xlabel=Processes,
ylabel=Run time (Seconds)
log ticks with fixed point
]
(1,0.005584)
(2,0.003083)
(4,0.001586)
(8,0.006259)
};

plot coordinates {
(1,0.036002)
(2,0.024381)
(4,0.014283)
(8,0.008018)
};

plot coordinates {
(1,0.334952)
(2,0.178412)
(4,0.092895)
(8,0.053607)
};
\end{loglogaxis}
\end{tikzpicture}
\caption{Number of processes against run time}
\end{figure}

In this case, you shouldn't use the log ticks with fixed point style, but rather set the format for the x axis tick labels to something like xticklabel=\pgfmathparse{exp(\tick)}\pgfmathprintnumber{\pgfmathresult}, which will evaluate the exponential expression and print the fixed point number. Note, however, that that will lead to curious tick values:

For your data, you should set the logarithmic basis of the x axis to log basis x=2, and the tick labels to xticklabel=\pgfmathparse{2^\tick}\pgfmathprintnumber{\pgfmathresult}:

\documentclass[]{article}
\usepackage{filecontents,pgfplots}

\begin{document}
\begin{tikzpicture}
\begin{loglogaxis}[
xlabel=Processes,
ylabel=Run time (Seconds),
log basis x=2,
xticklabel=\pgfmathparse{2^\tick}\pgfmathprintnumber{\pgfmathresult}
]
(1,0.005584)
(2,0.003083)
(4,0.001586)
(8,0.006259)
};

plot coordinates {
(1,0.036002)
(2,0.024381)
(4,0.014283)
(8,0.008018)
};

plot coordinates {
(1,0.334952)
(2,0.178412)
(4,0.092895)
(8,0.053607)
};
