I want to write chart data to file. LabView 7.1

[Capillod]

I am monitoring the output voltage from a electronic circuit using LabView 7.1 and a DAQ card.
I have been able to view the output voltage using a Waveform Chart but i have been unsuccessful sending the data to a file. Only one data point gets saved each time.
I am using the "Write to Spreadsheet File .vi "

Could someone tell me what i am doing wrong?

Please see the program attached below.

i created a small example how it work.

Basicly you have to create a shift register and a insert into array and thats it 🙂

please be aware that running a loop like in this picture generates lots of data to write into a txt file. That's why i put a pause after each run.
