Can i convert a xy plot that i get from my input values, into a circular shape in Labview?

Can i convert a xy plot that i get from my input values in the lab view, into a circular shape in Labview? i have attached an image its queit close to my plot, i want to convert this plot into a (rough/as close as possible) circular shape and then find a co-relation between an ideal round circle and the circle made by my xy plot that i have attached with the message.

 

Looking forward to listen from you soon,

 

Regards,

by that i mean that i need the final result close to a circle instead of the plot that i attached in my previous message.Is there any method in labview to do so? can i make the Initial point as the final point too? or some other way?

Just treat your values as polar coordinates. Labview has a vi to convert polar to complex (which you can then plot), see snippit below.

As for making the initial point the final point, just add that point to the end of your array(s).

So you mean to say that if my input is the signal given above by me then i can get a circular shape as output if i apply your methadology mentioned above. right?

I don't think anyone here understands what it is you want.  Traditional X-Y graphs have axes that go from negative to positive infinity so they really can't meet anywhere to form a circle.  Do you mean like a Smtih Chart?

The only points that i am getting in my xy plot are in first quadrant that is a problem for me. and the output is some how a non linear plot.
