tics

[grivet]

Thank you Adrien, your hint is just what was needed:

ticx = 0:1:5; ticxl = string(ticx);
.....
temp = a.x_ticks;
temp.locations=ticx;
temp.labels=ticxl;
a.x_ticks = temp;

works like a charm; however, the tlist doesn't work for me:

a.x_ticks=tlist(["ticks""locations""labels"],ticx,ticxl);

leads to

a.x_ticks=tlist(["ticks""locations""labels"],ticx,ticxl);
                                                          !--error 144

Are there constraints on the vectors ticx and ticxl?
