butterworth filter increases the time

[Mari3]

I wrote this labview program, but I am wondering why the time of the filtered signal (graph 5) is so big, does anyone know?

Thanks in advance

You're only graphing the data array which doesn't carry along any timing information.  So the X-scale of 'Graph 5' simply represents sample #.   You'd need to rebuild your waveform like this:

      

Note that there are also waveform-based filter functions you can find under the Signal Processing function palette.
