Updating an Array of Clusters of Indicators Issue

[Yamaeda]

It does look like the last value is repeated on the empty rows (did we just find a bug?), but it shouldn't be a problem (more than visually) since they're empty, they don't exist. If you were to use Index array and read out one outside the array i assume it's zeroed as it should?

Hello!

I'm new around here, first comment. But I just saw this and I found myself in the same situation some time ago.

What I would do: set the default value of your arrays with the elements not-initialized. When you want to display new data, clear it before with the invoke node "Reinit To Default".

I'm attaching one example.

Kind Regards,

Domingo

Still your post has nothing to do with the current discussion which talks about arrays of clusters.

I will just add a few comments about your code.

You are way over-using the "Reinit to default" property. It is very rarely needed.

There is absolutely no reason to reinit the indicator to defaults if you write a new value to it a nanosecond later. Also writing an empty array to the "values to add" would be much more efficient by using  a local variable.

Ah I see, thanks for pointing me that I didn't notice the full thing was a cluster.

In that case I could only recommend to use the number of rows property node (NumRows) to display from 1 to 4 when the array has less than 4 elements plus hiding the scroll bar.

When the array is bigger than 4 elements, then show the scroll bar (and put the NumRows in 4 if there weren't like this) thus, at least you get rid of a lot of non-initialize vectors elements. Still you will keep seeing the last elements as non-initialize (which can be workaround limiting the scroll position to not to show only the last element).
