i have a text code. i want to import to labview and display on waveform chart

Please put a little more detail about your question in the actual body of the message.

What do you mean by "text code"?   I assume you mean you have a text file of data.  If so, look at the read from spreadsheet file function.

thanks for that. i have the text file displaying on the chart now.

i am also looking to filter this signal. i am using a butterworth filter. the problem is when i am trying to put the values in from the spreadsheet it will only let me put in values from the first row. i am looking to put values in from all rows but when i connect the filters to all rows it reports an error. any ideas?

thanks

[RavensFan]

It's hard to come up with ideas without seeing the code.

[Barry1985]

attached the file there. in the read from spreadsheet function i am looking for all rows instead of first row but it wont let me.

thanks

Turn on context help (Ctrl-H) and hover over the function.

You have your wire connected to the "First Row" output rather than the "All Rows" output.

[Barry1985]

yeah i have seen that. when i put the wire through all rows it becomes a broken wire(see vi). the only way the vi will work is through the single row. i am looking for it to go through all rows. am i using the wrong type of filter? or should that matter.

[RavensFan]

Then your problem is a little different then you stated.  The problem is that you want to take 2-D data array and feed it into a filter that takes 1-D data.  You will want to put those functions in a for loop.  You can feed the 2-D array into the For loop and have autoindexing turned on.
