how to plot a continuous graph in a loop

    for k=1:10;
     x=5;
    y=2*x-5*k*k*k
  plot(k,y,'*');
    hold on;
end

 This program gives me a dotted graph. 
 however I wanted to get a regular(continuous) graph. 
 Please help me to find suitable command for that.

for k=1:10;
         x=5;
         y(k)=2*x-5*k*k*k;
         plot(1:k,y(1:k),'*'); % use the loop indices to plot in a loop
end

you can use the loop indices to plot the graph inside the loop

you can make your vectors and plot your graph, like:

s = [1 1 1 1];

t = [2 4 5 3];

G = graph(s,t);

plot(G);

but I need to get a graph for a loop in which k is known but 'y', that depends on 'k', gets its values in the loop itself
