Colors not showing in legend

Hello everyone, I am having problems with legends in plots... If I plot several things defining colors and using hold on, once used the legend command I don't see the color references... as example, after the following code:

plot(my_data(zone1,2),my_data(zone1,3),'b')
hold on
plot(my_data(zone2,2),my_data(zone2,3),'r')
plot(my_data(zone3,2),my_data(zone3,3),'g')
plot(my_data(zone4,2),my_data(zone4,3),'y')
plot(my_data(zone5,2),my_data(zone5,3),'c')
plot(my_data(zone6,2),my_data(zone6,3),'k')
legend('zone1','zone2','zone3','zone4','zone5','zone6')

I have the following plot:

Plot is fine and all references are there, but no colors...

Can someone help?

Thank you very much,

Fabrizio

legend('Zone1','Zone2','Zone3','Zone4','Zone5','Zone6');

Use a different variable name for legends. It seems you also use it as indices in your plot matrices.

Thank you for the answer!

It still does the same...

same with only legend, generating by default data1, data2 and so on

[VBBV]

are you plotting inside a GUI or App?

[VBBV]

legend({'Zone1','Zone2','Zone3','Zone4','Zone5','Zone6'});

or try using a cell array
