Way to create a Parabola in the XY Graph?

[C.Claudio]

I would like help on how to create a Parabola in LabView's XY Graph, I'm trying to create a Trajectory Graph in which I input velocity and the aiming angle so that it will output a Parabolic trajectory on the xy graph with the X Axis as Distance and Y Axis as Vertex or distance from the ground. Thanks

the xy graph cannot "create a parabola", just display one. 😄

So...  what you need to do is calculate you trajectory using the numerical tools, then display it on an xy graph. Where did you get stuck?

Are you looking for a numerical simulation (velocity, wind resistance, gravity, etc.) or for an analytical solution?

What have you tried so far?

[C.Claudio]

I'm looking to display a Trajectory in the XY Graph that dynamically change with the angle and speed input. I'm looking to calculate the trajectory in real time, changes in the inputs will dynamically alter the graph.

[altenbach]

Again, what have you tried so far? Did you find or derive a formula yet to implement? Once you have that, the rest is simple :D.

[C.Claudio]

Haven't tried aniything yet, still looking for a formula to put into the VI.

Parabola?

Trajectory (Uniform gravity, no drag or wind)

[C.Claudio]

Well, I actually need trajectory with drag effects, I want the graph to display the trajectory with no drag but with gravity and trajectory affected by gravity and drag. I would also want the chart to compensate for lift, since we are calculating a saucer object's trajectory.

[C.Claudio]

The graph must display height and distance of the object in a 10 Second time frame , 1 per each second to plot all points. The problem is how to do that the VI calculates all the plot points then cluster it all to a XY Graph

It sounds like a school project, right?

It seems that you have three parts to the problem:

1. You need to create a model - the equations - which describe the physics of the system. You will have the mass of the object, the initial angle and velocity (or force), the gravitational force, the drag force, lift, and time.

2. You need to implement the model in a LabVIEW program.

3. You need to display the output of the model on a graphical display, apparently constrained to be an XY graph.

If this is a school project, we do not do your work for you.  You do not learn anything when someone else does all the work.

Now, tell us which of the three parts is giving you trouble. Show us what you have tried. We are glad to help you learn, but you must make a significant effort to help yourself. Tell us what it is that does not work as you expect.  We cannot guess what your problems might be.

Have you taken any LV training or worked through the on-line tutorials? They are a good place to start if you are new to LV.

#2-3, I can't find a tutorial on how to implement a model to the XY Graph, I can't think on how to combine 10 plot points into one XY Graph then have the graph form lines between the plot points. This is actually not a school projectand I am actually asking for ideas on how to implement it , I don't want a completed VI to be posted here.
