I want to plot this graph in beamer and I don't know how! I want plot step by step this graph..

Step 1:

enter image description here

Step 2:

enter image description here

Step 3: enter image description here

Step 4: enter image description here

I write this follow




% Declare layers

\frametitle{Prim's algorithm}

%% Adjacency matrix of graph
%% \  a  b  c  d  e  f  g
%% a  x  7     5
%% b  7  x  8  9  7
%% c     8  x     5
%% d  5  9     x 15  6
%% e     7  5 15  x  8  9
%% f           6  8  x 11
%% g              9  11 x

\tikzstyle{vertex}=[circle,fill=black!25,minimum size=20pt,inner sep=0pt]
\tikzstyle{selected vertex} = [vertex, fill=red!24]
\tikzstyle{edge} = [draw,thick,-]
\tikzstyle{weight} = [font=\small]
\tikzstyle{selected edge} = [draw,line width=5pt,-,red!50]
\tikzstyle{ignored edge} = [draw,line width=5pt,-,black!20]

\begin{tikzpicture}[scale=1.8, auto,swap]
    % Draw a 7,11 network
    % First we draw the vertices
    \foreach \pos/\name in {{(0,2)/a}, {(2,1)/b}, {(4,1)/c},
                            {(0,0)/d}, {(3,0)/e}, {(2,-1)/f}, {(4,-1)/g}}
        \node[vertex] (\name) at \pos {$\name$};
    % Connect vertices with edges and draw weights
    \foreach \source/ \dest /\weight in {b/a/7, c/b/8,d/a/5,d/b/9,
                                         e/b/7, e/c/5,e/d/10,
        \path[edge] (\source) -- node[weight] {$\weight$} (\dest);
    % Start animating the vertex and edge selection. 
    \foreach \vertex / \fr in {a/1,b/2,d/3,c/3}
        \path<\fr-> node[selected vertex] at (\vertex) {$\vertex$};
    % For convenience we use a background layer to highlight edges
    % This way we don't have to worry about the highlighting covering
    % weight labels. 
        \foreach \source / \dest in {b/a,d/a,d/b,c/b,e/b}
            \path<+->[selected edge] (\source.center) -- (\dest.center);
       % \foreach \source / \dest / \fr in {d/b/4,d/e/5,e/f/5,b/c/6,f/g/7}
          %  \path<\fr->[ignored edge] (\source.center) -- (\dest.center);



and problem is 1- my edges of graph is directed but this graph is not 2- in my graph steps are Sometimes chose double which means that in step b and d both chosen by a but this command step by step!!

    You may want to add a minimal code frame, to show us what you've tried already and where you fail

  • I don't know how write this code! :(

    @maedeh At least, please include the code to generate the graphs, and the preamble that loads beamer.

  • If you have nothing to start with, maybe a good starting point would be the answer in this queston: tex.stackexchange.com/questions/99119/…

To make things only appear not immediately on a frame you can use \onslide<2-> What you want to appear\onslide<1->. Everything you write in between the two \onslide commands will only be visible on the second part of the frame. So in your example you want something like that:

         %Draw your graph(always visible)
         %Draw the red lines(only visible on the second part of the frame)

The last \pause is necessary so that there is a chance to enter the second part of the frame where the red lines are shown.

  • problem is here I don't know how draw my graph!

  • I think you should take a look at these examples: texample.net/tikz/examples/tag/graphs
