Why is my plot not showing any line?

im writing these codes but when i run it i cnt see any line, could u plz help me

for i = 1:5
   Iph = (Iscr+ki*(T-Tr))*((S(i))/100);
   Irs = Irr*((T/Tr)^3)*(exp(q*Eg/(K*A)))*((1/Tr)-(1/T));
   I0 = Np*Iph-Np*Irs*(exp(q/(K*T*A))*(V0./Ns)-1);
   P0 = V0.*I0;
   
   figure(1)
   plot(V0,I0);
   axis([0 50 0 20]);
   xlabel('Voltage in volts');
   ylabel('Current in Amps');
   hold on;
   
   figure(2)
   plot(V0,P0);
   axis([0 50 0 400]);
   xlabel('Voltage in volts')
   ylabel('Power in watts');
  hold on;
   
  figure(3)
   plot(I0,P0);
   axis([0 20 0 400]);
   xlabel('Current in Amps');
   ylabel('Power in Watts');
   hold on;
end

You don’t need a loop , just remove for i=1:5 and end

upload the missing datas to run your code , also try putting dots before arithmetic operators in the mean time and try again
