How can I build an array using two numeric controls and a button? Whenever I press the button a column of 2 rows (the numeric controls) should be created.

I tried many ways so far. 

I know that I can use build array to create an array from two numbers but Im not able to create a 2d array that way

I also tried using Replace array subset but still it wont work.

I know that I have to use an array function that has column index starting at 0 so whenever I press the button the column index incriments by 1 so the next column will change but Im not able to create this.

You want it to add to your current array? Here's a good way using an event structure:

Here's a screenshot to explain myself better.

In this case however, whever In press the button the first column is replaced. 

I want to change the next column whenever I press "next point".

Download the VI attached to my previous post and try it out! I think it does what you want.

Greatly appreciated 🙂

No problem! You may want to mark my first post as the solution instead, for future generation's benefit 😄

• I don't understand the purpose of the timeout case. All it does burn CPU cyclces as fast as the computer allows, constantly writing the same stuff to the array indicator. remove it.
• If you would wire the array indicator before the event structure, it would reset correctly at the beginning of the program. Now you can even use the same event for stop and add, because nothing gets appended to the indicator when you stop. Only one event case needed overall, simplifying the code.
• It would be much simpler and efficient to add rows instead of columns. Adding columns is expensive in terms of memory management.
• If the final array size were known, things could be made significanttly more efficient.

You're the authority on this one Altenbach! Writing this one, I just made it to have it work. Didn't really consider all of that. Here's a modified version for the OP to use should he like:
