How can I combine two curves ,?

Hello

How can I combine this two figures in one curve like the Wanted figure ?

[madhan ravi]

hold on?

[Mallouli Marwa]

How can I add it in the Main prog

[madhan ravi]

after the first plot command

doc hold 

[Mallouli Marwa]

I have obtain just one curve.

Please see my progr

This is how I would do it:

loglog(R_load,v0,'b',R_load,v05,'m',R_load,v1,'g')
hold on                                                                 % <— ADD ‘hold on’ HERE
%orange = [1 0.5 0.2];
%line(freq,v1, 'Color', orange);
legend('ratio 0.0','ratio 0.5','ratio 1')
xlabel('Load resistance  (\Omega)')
ylabel('|Voltage FRF| [V/g]')
Nice_Fig(h,0,lw)

[Yongming Sun]

Can I add labels to each curves by using 'hold on & off'?

Yongming Sun —

To add labels to the curves themselves, use the text function.
