Error in axis range

Hello guys,

I'm developing a code for an aerodynamic project and there is an error showing up in the range of the axis value that i used in the graphic.

The axis range that i wrote is:

figure
 axis ([0 Jmax 0 1.1*Tmax ]);
 plot(J,CT,J,CQ,J,CP);
 title('Thrust, Torque and Power Coefficients');
 xlabel('Advanced Ratio (J)');
 ylabel('Ct, Cq and Cp');

As Tmax being equal to max(T).

Can anyone help me with the error?

If i don´t use the range valuespecification for the axis, the values cannot be measured with high accurancy.

The axis call should go after the plot call:

Jmax = 5;
Tmax = 2;
J = 0:Jmax;
CT = rand(size(J));
CQ = rand(size(J));
CP = rand(size(J));

figure
plot(J,CT,J,CQ,J,CP);
axis ([0 Jmax 0 1.1*Tmax ]);
xlabel('Advanced Ratio (J)');
ylabel('Ct, Cq and Cp');

.
