Moving Points in 3D Curve

[Gao1219]

Hi,

I am new to LabVIEW user here 

I wanted to create a 4 moving plots as picture below:

 

However, I have no idea how to make those points move. 

I have attached my labview here.

Please help. Thanks!

Hi Gao,

your VI plots 4 points and 2 lines.

In this picture nothing is "moving"…

To anmiate those points/lines you need to change their coordinates over time. I suggest to use a loop with some timing inside and a list of coordinates (or some formulas describing the position of objects as function of time)!

Are you sure this is your VI? Why don't you provide a link to the website where you found it?

Hey GerdW,
Thanks for your reply!

I am so sorry for my poor choice of words.
I am using the VI from https://forums.ni.com/t5/Example-Code/Graphing-3D-XYZ-Scatter-Plots-and-Lines/ta-p/3531017

I am working on the animation of signals recorded from accelerometer to a point moving with time. Will it be the same method as what you mentioned?

Hi Gao,

the VI just draws some points and lines.

When you call that VI several times with changes coordinates for all items then you can animate the points and lines…

Hey GerdW,

Thanks for your opinion!

Do you have any example for the method you mentioned? 

Best regards,

Gao

Calling subVIs in loops is very basic LabVIEW stuff, so I suggest to take the "Training resources" found in the header of the LabVIEW board…

that's interesting... the NI example code you attached can be run in Labview 2019 32 Bit

but not in Labview 2020 64 Bit

Do you use LabView 2020 32 Bit?

by changing the XYZ coordinate?

Hey Alex,

I'm trying to create similar motion in the YouTube link below (1:55)

Thanks!

so there are at least two ellipses - with varying parameters a and b -  defined by the same number of x,y point,

and each point of each ellipsis is connected to another - indicated with a ray between those 2 points?

I would build 3 individual plots and stack them together to one XY graph like this:

good luck
