Doing a plot within a FOR LOOP

I want to plot all values of B for changing i from following code;
clear
for i = 0.04 : 0.01 : 0.06
B = -20000 + 57300*((1+i)^-20)
plot(i,B,'-ro')
axis([0 0.06 -2134 6152])
i=i+0.01;
end
I put the axis line in as the plot was showing much vaguer values? It only shows one final plot for i=0.06 so could someone help me please??
Thanks

some thing like this?
clear
for i = 0.04 : 0.01 : 0.06
B = -20000 + 57300*((1+i)^-20)
figure()
plot(i,B,'-ro','markerSize',10)
axis([0 0.06 -2140 6160])
% i=i+0.01;
end
EDIT- For all on the same plot-- no need of for loop at all
i=[0.04:0.01:0.06];
B = -20000 + 57300*((1+i).^-20)
plot(i,B,'-ro','markerSize',10,'LineWidth',1)
axis([0 0.06 -2140 6160])

hmm this gives me three seperate plots for each value whereas i would like a plot that shows a line with gradient joining the points for each value of i??
Please check edited answer..
Thank You! perfect.
