Fractional Pi Tick Labels

Format axis tick labels as fractions of pi.

Change the x or y axis tick labels to be formatted a fractions of pi. Separate functions are provided for adjusting each axis independently.

xlabel_pi_fractions;
ylabel_pi_fractions;

You can specify the maximum divisor, N, for which all ticks will be multiples of . If not specified, the default divisor is 4.

h = axes;
axis(h, [-pi pi 0 2*pi]);
xlabel_pi_fractions(5);
ylabel_pi_fractions(2);

Similar to other graphics commands, you can optionally provide a handle to the axes object as the first argument.

h = axes;
axis(h, [-pi pi 0 2*pi]);
xlabel_pi_fractions(h, 5);
ylabel_pi_fractions(h, 2);
