for le = les:100:len
t=max(tf,tw);
if t <=16
f = 0.9*fy;
elseif 16 < t <= 35
f = 0.85*fy;
elseif 35 < t <= 50
f = 0.80*fy;
elseif 50 < t <= 100
f = 0.75*fy;
end
N1 = f*Ag;
wx = le/rx;
wy = le/ry;
w = max(wx,wy);
%fprintf('w = %5.6f\n',w);
Qxy = sqrt((fy/235));
%fprintf('Qxy = %5.6f\n',Qxy);
Wxy = round(w*Qxy);
%fprintf('Wxy = %5.6f\n',Wxy);
Py = mod(Wxy,10);
%fprintf('Py = %5.6f\n',Py);
Px = Wxy - Py;
%fprintf('Px = %3.0f\n',Px);
xx = Px/10+1;
%fprintf('xx = %3.0f\n',xx);
P = scn(xx,Py+2);
%fprintf('P = %5.3f\n',P);
N2 = N1*P*10^-3;
plot(le,N2);
end
I need to plot N2 vs le graph, im not getting any error code but the graph is just blank. not even a point.

use the line specifications and marker size to identify the plotted points
plot(le,N2,'*k','Markersize',12)
  • If above command not solve your problem post the entire code/ missing values in the code already posted .So that somebody can trace the bug easily

Thank you so much, now all the dots are shown on the screen xD. Is there any way that i can join the dots together to form some sort of trend lines?
