# pgfplot gives me “could not parse input ” as a floating point number, sorry."

I am trying to create a plot, and while I am very new to LaTeX, I feel like I've gotten a good feel for it. However, I cannot seem to fix this error:

Package PGF Math Error: Could not parse input " as a floating point number, sorry. The unreadable part was near "..


I have tried for 2 hours now, to find any solutions to no avail. Can anyone guide me?

Here is my code:

\begin{center}
\begin{tikzpicture}
\begin{axis}[width=13cm,height=6cm,
title={something},
ylabel={rente i \%},
xmin=1988, xmax=2019,
ymin=-2.0, ymax=12.0,
xtick={1989,1992,1995,1998,2001,2004,2007,2010,2013,2017},
ytick={0.0,2.5,5.0,7.5,10.0,},
xticklabel style={/pgf/number format/1000 sep=,rotate=60,anchor=east,font=\normalsize},
legend pos=north east,
ymajorgrids=true,
grid style=dashed,
]

color=black,
mark=pentagon*,
]
coordinates {

};

\end{axis}

• LaTeX errors are not alway easy to guess the meaning of -but you can always uncomment lines until you have a bare minimum that works -and from there slowly find the line and exact thing that is causing the problem. – hpekristiansen Mar 14 '17 at 16:39

pgfplots is expecting another number in a list. Change ytick={0.0,2.5,5.0,7.5,10.0,} to ytick={0.0,2.5,5.0,7.5,10.0} (remove the comma before the }).
