Graph of complex number in Argan plane

[rsduarte]

I need help to do a graph with Voltage and Current Phasors in Three-Phase Systems.. I have a graph of complex numbers, but I want a arrow in the end, to represent a vector.

You can use an XY graph or a polar plot created using a picture indicator. Here's how you can do it using a polar plot:

To get the polar plot simply go to the front panel and select Graph -> Controls -> Polar Plot Indicator. Doing this will place a picture indicator as well as some code on the block diagram.

Thank you but I already saw it. But that is not what I want.. I need the complex number in Cartesian representation z = x + iy. A XYgraph with coordinates real and imaginary. I already have the complex number in XYGraph but I want a arrow in the end, to seem like a vector.

Then you will need to draw this. The XY graph doesn't have the capability of drawing arrows unless you do your own drawing on the Plot Images. However, if you're going to do that you might as well use the picture-based XY graph. Have you tried a search? If you did you would have quickly come with this example.

I solved my problem

I represent more two points and connect them..

Thank you.

Hi  could you convert your VI in to LabVIEW 7.0, so I could test it.

Please

Thanks

Going back to 7.0 is a bit of trouble.  But that VI would be easy enough to recreate from a screen shot.

I have tried to recreate it with your screenshot, but when I connect the build array to the XY Graph, it gives an error

“You have connected two terminals of different types:

The type of the source is 2-D array of single complex [~6 digit precision].

The type of the sink is cluster of 2 elements. “

Is there any property from the XY graph that I need to know, to fix this?

[RavensFan]

Please post your VI.  The XY graph should have automatically adapted to the array input.
