How do I constantly update an array in LabVIEW?

[kmarking]

I'm trying to use the Polar Plot VI under Picture Plots so that I can plot spatial data as it is received. The problem is that the Polar Plot VI accepts a data array input, but there is no way for me to update the input array as data is coming in.

Basically, I'm trying to create a module that does the following:

integer i = 0;

1. Take numerical input.

2. Place element in array at index i. Increment array index by 1, i=i+1;

3. Send array to Polar Plot VI.

4. Update picture plot to reflect current contents of array.

5. Repeat.

I just installed LabVIEW a few hours ago and have been trying to figure out how to achieve my goal by searching the web, but have not found anything useful.

You should start with some tutorials. Then you should build your array in a shift register. There are plenty of examples in the forum.
