I need to plot a graph of P, Rdia and Vo, please help me how to get graph. (for every 10 increment of pressure, there is 1 ohm increment of Rdia , and display the output vo)

Rdia = 3673; % dia resistance value in ohm ;
Rtemp = 3618; % Temperature resistance value in ohm;
R1 = 3600; % fixed resistance in ohm;
R2 = 3600; % fixed resistance in ohm;
Rof1 = 150; % offset compensation resistance in ohm;
Rof2 = 200; % offset compensation resistance in ohm;
Vexc = 0.748; % excitation voltage;
for P = 0:10:300 % pressure increment to 10 mmHg
P
for m =1
if (P == 0)
Rdia_new = Rdia
x = Rdia_new/(Rdia_new+R1);
y = (Rtemp+Rof1)/((Rtemp+Rof1) + (R2+Rof2));
vo = ((x - y)*Vexc)*1000; % output voltage in volts
disp(vo)
else
Rdia_new = Rdia+m
Rdia =Rdia+1;
x = Rdia_new/(Rdia_new+R1);
y = (Rtemp+Rof1)/((Rtemp+Rof1) + (R2+Rof2));
vo = ((x - y)*Vexc)*1000;
disp(vo);
end
end
