How do you get an indicator array to output a DBL function?

[jowens]

I am learning the program and I have a newer version than what my tutorial is setup for. I am expected to in this tutorial to set-up an array to display a numerical answer to go with the output graph. However the the data type accepted by the array doesn't say "DBL" it is merely a blank black square bracket as such
"[ ]" If this has no real importance than I don't beleive I need it for an output unless I was trying to get the program to take a reading from the graph.

In regards to your question: (get an indicator array to output a DBL?) your array will output the data and data-type that it holds. If your array holds DBL, it will output DBL, same with Strings, etc.
Your first step should be to evaluate the type of data in your array, and if you need to convert between data types, you should study the conversion VIs available. Also, see if you should convert the data going in to the array or convert the data out from the array. Depends which is most suitable. Good Luck - Doug

When you create an array, you have to define the data type. When creating an array indicator, also create a numeric indicator and drag it to the inside of the array. You can right click the numeric to change the representation.
