Help me turn this nice looking wave into a message!

Note Assume each waveform = (+-) 0.5

• At the end I see BG in there, followed by 'U'. Did you want to tell me something? :P – Beastly Gerbil Mar 17 '17 at 16:56
• @BeastlyGerbil The message is for the one who finds it. So, it may be you. Who knows :-) – Techidiot Mar 17 '17 at 18:21
• @humn Looks amusing isn't it? But tbh, it is not a part of message but serves a purpose in guiding how to look at the wave. :) And yes, I was motivated by your puzzle designs for making this one. – Techidiot Mar 17 '17 at 19:12
• Thanks to the compass lettering and your ascii visuals, user @Techidiot, my screen is now happily sideways and in a monospace editor. – humn Mar 17 '17 at 19:16
• @humn I just used my mobile to view the puzzle. It seems the mobile browser doesn't show the letter "S" on the compass correctly. But anyway, one can assume it :) – Techidiot Mar 17 '17 at 19:32

The message turns out to be:

That is how you roll.

The curve can be rotated, so that the abscissa points right instead of downwards and the ordinate points upinstead of right¹.

In order of increasing abscissa values, the message reads:

KMNSTPXXNIRJSBGU

The letters sit on alternating minima and maxima of the sine curve, so let's take the next or previous letter in the alphabet depending on whether the the ordinate value is negative or positive:

LLORUOYWOHSITAHT

Now read the message bckwards³ and insert spaces as appropriate.

________
¹) The compass rose and the scale were supposed to hint at this, but it turns out that the rotation isn't really needed.

²) It is not clear why the absolute value of the extrema should be 0.5 uniformly. First, the X and U are closer to the x-axis than other letters and the absolute value of the minima and maxima differs visually (15 vs. 13 spaces). And why 0.5? Maybe I'm missing something here.

³) I don't think that there is any hint towards reading the message backwards; it's just observation.

• @M Oehm - 1) I thought I made it a little difficult to interpret and hence added those values to make it simpler. :-) You just need to bring -0.5 to 0.5 hence add 1 to the letter similarly for 0.5 to -0.5 remove 1 from the letter. 2) The values as said were just assumptions as I didn't drew exact curves. 3) Yes, no hint for going backwards just to add a little twist :-) PS - If you see the edit history, I didn't had the values nor the turn thing. Nice work! :) – Techidiot Mar 21 '17 at 12:58
• ...So It was just everything I thought of? aww darnit – lol Mar 22 '17 at 12:28
