I tried removing the header lines which i deleted but i am still unable to show the colmn names.
my current vl look like this
well, you still delete zero columns beginning from column #7. Don't know what you want to achieve with that operation...
"I tried removing the header lines which i deleted"
First you deleted some lines and then you try to remove them???
See attachment. It uses those header lines to display the column headers.
Sometimes it really helps to read the context help for LabVIEW primitives...
This is a 2 year old thread unrelated to your question. There are many other threads that are more pertinent in discussing NaN.
If you remove an NaN from a 2-D array, what you really want it to do? Do you want to replace it with something else?
I don't know how a toolkit directs you to a forum thread.
Look at the comparison palette, you'll see a comparison for "Not a Number". Use that when indexing through an array to determine whether to replace with zero.
