Mindmap tikzpicture in beamer (reveal step by step)
Using a mindmap example from here, with only sligth modifications. The target is to control what mindmap pieces are visible at a given time in the presentation.
Here is what i tried:
\begin{tikzpicture}
\path[mindmap,concept color=black,text=white]
node[concept] {Computer Science}
[clockwise from=0]
child[concept color=green!50!black] {
node[concept] (herb) {practical} %herb
[clockwise from=90]
child { node[concept] {algorithms} }
child { node[concept] {data structures} }
child { node[concept] {pro\-gramming languages} }
child { node[concept] {software engineer\-ing} }
}
child[concept color=blue] {
node[concept] (muh) {applied} %muh
[clockwise from=-30]
child { node[concept] {databases} }
child { node[concept] {WWW} }
}
child[concept color=red] { node[concept] {technical} }
child[concept color=orange] { node[concept] {theoretical} };
\uncover<1-1>{herb} %should uncover on 1
\uncover<2-2>{muh} %should uncover on 2
\end{tikzpicture}
Although i get to select the two different versions in the pdf, they appear identical. How can i display the mindmap step by step to help my audience follow my trail.
