Horizontal axis in terms of pi

[fizzy]

Hello all..

When creating a 2D plot, is there a way to have the plot show the horizontal axis ticks in terms of pi rather than real numbers?

Here's a simple plot of f(x) = 2sin(4x)

The horizontal axis shows -10, -5, 0, 5, 10

I would like to add more ticks to this, but more importantly I would like them to be in tems of pi.

I looked through some of the previous posts, and MC 15 help, but I haven't found anything pertinent.

Any ideas?

Thanks

Select end point of the x-axis as multipes of pi

Thanks for the file and the quick response, but the x-axis on your plot consists of real numbers, not in terms of pi.

Unfortunately - no. Thats another rather old, long standing but unheard user request.

As long as you want integer or inter fraction multiples of pi displayed - yes. If you are happy with decimals representing multiples of pi you may try what David suggested.

The best I can come up with is this (and the x-axis labelling is abit confusiong because of the missing pi)

Thank you......I could just copy the plot and then past in the values, but I was just flabbergasted this couldn't be done in mathcad.

Thanks Werner

Its indeed often surprising how apparently simply features are missing in otherwise high end software products.

The result is just like all plots with units, and here pi is a unit. For plots with x as a distance in ft, for example, we don't see "ft" at each tick mark. Instead, we see numbers in the selected unit. We select the unit by dividing x by the unit, just as you have done with pi.

To show the units, create a label for the x axis, such as "angle in pi"

Yes I know and using pi as a unit here is just a weak workaround to get closer to what Thomas had originally requested (and a lot of simple plot programs do offer).

I also tried it in Prime - here you can put the pi in the unit placeholder of the axis label, but you have to define pi:=pi before, labelling the lefthand pi as unit.

Wish Mathcad would be able to label in multiple/fractions of pi without having to resort to this trick.
