Question: How to make a radar simulation on XY Graph?
已解决！
What exactly do you mean by simulation of a radar?
Attach a picture of something that looks like what you want. (We already know what the current LV graph and the express VI look like.
)
An xy graph just displays the data. The "simulation" (whatever that means) needs some code implementing the model.
Showing us pictures of an express graph does not narrow down the ambiguity and they are not needed to explain what you are trying to do.
A real radar simulation might need an intensity graph, showing the radar echo intensity as a function of direction and distance. You could simulate a 2D world with some objects and given radar reflectivity, the canculate the profile for each direction.

Use a complex array with two points, one at 0,0 and the second one in sherical coordinates where you keep R=1 and increment theta linearly (wrap at 360 degrees). Ise an appropriate delay.
What is your LabVIEW version?

You can't use it in conjunction with the Build XY Graph express VI because that creates a history and you'll see multiple lines.
The history can be turned off, but the express VI is still overkill. Here's what I had in mind earlier, modify as needed.
It is NOT a "radar simulation" (as I defined earlier), but just a rotating line. 😄
(note that you can leave out the IQ&R. I placed it there so you could display the wrapped angle if desired)
