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
