Wrong with function 'plot', maybe

Question

I want to calculate Nodal clustering coefficient distribution with a connectivity matrix But when I operate this code, it return nothing. What is the problem? Can't I use function plot like that?

cm = [0,1,1,1,0;1,0,0,1,0;0,1,0,0,0;1,0,0,0,0;0,0,0,0,0];
bg = biograph(cm);

for i = 1:5
    intNodes = getrelatives(bg.nodes(i));
    num = numel(intNodes);
    plot(i,num);
    end

Each call to plot will erase the previously plotted data, unless you write

hold on

before the loop (or unless you edit the axes properties).

cm = [0,1,1,1,0;1,0,0,1,0;0,1,0,0,0;1,0,0,0,0;0,0,0,0,0];
bg = biograph(cm);
figure %# create new figure
hold on %# create axes, make sure that plots get added instead of replaced
for i = 1:5
    intNodes = getrelatives(bg.nodes(i));
    num = numel(intNodes);
    plot(i,num);
end

Your code is probably going to run better if you first gather all the data points, and only plot them in the end. Here is how this can be done:

cm = [0,1,1,1,0;1,0,0,1,0;0,1,0,0,0;1,0,0,0,0;0,0,0,0,0];
bg = biograph(cm);

plotData = NaN(5,1)
for i = 1:5
    intNodes = getrelatives(bg.nodes(i));
    num = numel(intNodes);
    plotData(i)=num
end

plot(1:5,plotData)
