I'd like to have in @interact a slider for (0,2pi) with stepsize 0.05pi that shows as label $\alpha$ and the current value only in the format $x*\pi$

Comments

So make a slider from 0 to 2 with step size 0.05 and then multiply that x by pi. Did you have some trouble doing that? What did you try?

Wouldn't a slider for $x_r\in\left[0~1\right]$ and a label reporting "\alpha = 2\pi{}".format(x)do the job ? Of course, in the computation, you'd have to use $\alpha=x_r\cdot2\pi$ . So what ?

The current value from the sliderr is displayed to the right of the sliderr - that would show the value of x_r, but I should like to see there that value augmented by $\cdot2\cdot \pi$ .
