Graphics, Figures & Tables ⇒ pgfplots | Animation in Presentation

[duboismathieu]

Hello,

I have recently discovered pgfplots and I wanted to use it for a beamer presentation.

The figure is a bar chart (more precisely ybar meaning vertical bars). There are several (symbolic) x values and several plots. Here is a simple example (borrowed from pgfplots manual p27):

Code: Select all

\begin{tikzpicture}
\begin{axis}[
ybar,
enlargelimits=0.15,
legend style={at={(0.5,-0.15)},
anchor=north,legend columns=-1},
ylabel={\#participants},
symbolic x coords={tool8,tool9,tool10},
xtick=data,
nodes near coords,
nodes near coords align={vertical},
]
\addplot coordinates {(tool8,7) (tool9,9) (tool10,4)};
\addplot coordinates {(tool8,4) (tool9,4) (tool10,4)};
\addplot coordinates {(tool8,1) (tool9,1) (tool10,1)};
\legend{used,understood,not understood}
\end{axis}
\end{tikzpicture}

What I would like to do is to x values one after another: slide 1 should show the three bar for tool8, slide 2 adds the three bars of tool9, etc...

Any idea?
Thanks in advance.
