calculating mean value of sorted data and drawing polar plot

[MrHUU]

Hi,

I managed to create that index buffer. My new VI has been in use for over a week, and it works wonderfull.

Only thing what I've been unable to solve is how to turn face plate of polar plot. It's not neccessary, but would be just a nice addon detail.

What I've been trying to do is:

- turn North up (now on right, where east shoud be). I managed to change numbers, but that doesn't affet where drawing start.

- degress growing clockwice (now growing counterclockwice). Have no clue how this could be done.

Hi MrHUU,

"- turn North up"

That's a phase shift of PI/2...

"- degress growing clockwice"

Negating the degrees to turn the direction?

Thanks for fast answer.

this is how my polar plot is drawed at the moment. North on right, and degrees going counter clockwice.

this is how i would like my polar plot to "looklike". So, Noth up and degrees going clockwice.

I could try that pahse shift trick, but would it change front plate numbers aswell, or do I have to change those 4 values inside polar plot vi, like I have tried to to earlier.

Hi MrHUU,

right now you have N=0°, E=90°, S=180°, W=270°

You need: N=90°, E=0°, S=270°, W=180°.

So you need to calc: degree_new = 90 - degree_old to get the correct "phase".

Do you plot just points/lines or present "real" values (as numbers) on your compass?

[MrHUU]

Thanks for the tip. It did work 🙂

I'm drawing points connected with lines. I changed numbers to letters N, E, S, W, this is enough close for me.

Please can you email me your vi to tawandamukanhairi@gmail.com , i am trying to do something like this
