Triangular wave form plot

Hi, I'm trying to generate a 140Hz triangular wave.
Following code produce the correct plot up to 100HZ. Once I enter the value beyond 100hz (eg 140hz) the plot doesn't seems to be correct.
t=0:.001:1.5 ;
x = sawtooth (2 * pi * 140 * t , 0.5); % 0.5 specify a symmetric triangular shape
plot(t,x); axis ( [ 0 0.01 -1 1 ] );
Is it some thing to do with the code of the plot figure settings?

sawtooth() already does a 2*pi conversion internally. A value of 1 for time corresponds to one full cycle of the triangle wave. Your pre-multiplication by 2*pi is throwing that off.
