easy way to adjust axis labels to match x inputs

Hello,

Does it need a for loop somehow?

I need the values on the x axis to show in radians, counting from 0 to 3pi, counting bu pi/20...

Graph is a simple cosine function

I doubt that is what you really want.

figure
ax = gca;
x = 0:pi/20:3*pi;

y = cos(x);

plot(ax, x, y);
xticks(ax, x);
xticklabels( ax, string(0:1/20:3) + "\pi");

I think it more likely that you only want occasional axes labels.

figure
ax = gca;
x = 0:pi/20:3*pi;

y = cos(x);

plot(ax, x, y);
xt = x(1:10:end);
xticks(ax, xt);
xticklabels(ax, string(0:1/2:3) + "\pi")

Hello, thanks for offering feedback so fast. This bit of code is quite helpful. I'm in an intro to signals course right now and learning. Will make sure to credit new internet MatLab friends. The code I had was using xticks and xticklabels enumerating each tick mark, which ends up being cumbersome.
