Error 20023 ocured at filters

[Bildavid]

Please guys I need you to cooperate with me . everytime i run my vi it gives me error 20023 at filters and it says that high cutoff must be greater than low cutoff and lower than fs/2 . I understand these conditions and i followed them but still getting the same results.

any suggestions guys ? :S

Iam using version 2009 

can you guys correct my mistake if any ? 

Thank you .

Hi Bildavid,

you may receive that error also when not supplying any data to the Butterworth filter (empty data array)...

You really want to filter with the settings in your VI (lowpass, 2nd order, 8000Hz sample rate, 0.125Hz lowpass)?

Dear GerdW

One more thing I am going out of my mind :S

I have a waveform chart that displays a signal .if i turn autoscale X and autoscale Y the signal is appearing good until the whole waveform chart looks like a spring that gets compressed more and more as long as data are displayed . 

I just want to display the data (signal) so that it is updated with time without remembering the first signal. I hope i made my point clear . 

I hope you can cooperate with me .

thanks a lot .

For that you want to use a Waveform GRAPH instead of a chart.
