Wrap text from bottom to top

[maxnoder1995]

How can I implement text wrapping from the bottom to the top in LabVIEW? I'm looking for a solution to format my text in a way that it starts at the bottom of a text box or display area and wraps upwards, rather than the standard top-to-bottom approach.

So your text is one long string without line delimiters and you want it to dynamically re-wrap if the font size or indicator dimensions are changed?

I assume you are talking about an indicator, not a control, right?

The math will be a bit easier if you use a fixed width font (e.g. Consolas).

Can you explain the purpose of all this?

If each line is a linefeed delimited string to be dynamically appended to the indicator, all you might need is concatenate the new data on top.

Saved by "going through a tunnel".

I (carelessly) read this post, and thought the Original Poster had a ListBox (which is what I thought he meant by "Text Box") and wanted to present it with the initial Selected Item the last item in the list (instead of the first).  By the time I got off the train and was able to set up my laptop again, I saw the posts from Christian and Paul, and figured out that I was "answering the wrong question".

That's a bit of a hack, because applying the operation twice does not restore the original string as one might foolishly expect. Might be OK is some use cases.

(Easiest to demonstrate by repeating the operation a couple of times. We get more and more empty lines in-between the text lines. Not easy to fix.)

OK.  Just remove the concatenation of the End of Line Constant and it will work as you like.
