I want Labview functions Joe, any suggestions ?
Dennis,
You have given me links to a Print VI that prints the whole front
panel. How would I make this VI functional for printing just a graph
or table in the front panel ? Also, the Print Dialog VI that you
pointed at, does not have the option of selecting number of copies for
prin
Thanks for the info Dennis.
How do I interface with C-code through Call Library Function?
And what is the difference between Call Library Function and Call
Interface Node ?
Thanks.
I am trying to save a multicolumn data to a text file without using
Report Generation VIs. Here is the detail scenario...
I have data in the following format.
Time Voltage
1 2
2 3
3 6 ...
and
Power
1
and
Peaks
x-axisy-axis
Peak1 1 4
Peak2 5
What you have said is really informative. Thanks a lot!
You suggested not using a window, but if I try without one, the
spectrum is crowded without any clear pattern showing up. I think not
removing the dc, was the problem why that high value for 0.0033 HZ
showed up. You talk about bins here, how
Are you talking about Labview Tools here or something else ?
Question 1: Where would I find the Print Dialog VI, so that a user has
the access to select his desired printer, no of copies for printout
and so on...
Question 2 : How would I print a Graph on the front panel without
using Report Generation VIs ?
Hope I get the answer to these questions.
Thank
Hi Joe,
Thanks for the info. Do you know any site that has examples related
to this task ? Please let me know.

Thanks Juan.
It sounds simple if we just save the data, but here I have to enter
few text entries and write values beside them. For example, if we have
results like..
Voltage 5 V
Current 2 mA
Power 1 mW
What VI do you use to save the entries like this in the file. I don't

Here is what my work is all about. I am trying to develop a software
for Heart Rate Variability analysis. I am not sure if you are aware of
heart beat waveforms, they are bunch spikes, occuring at irregular
intervals. We have to do analysis on this waveform. How ? First we
have to create a plot cal
I got to point out something here. The vertical axis unit for the time
domain signal is milliseconds,and not volts. I am a bit lost here,
would the term DC apply to our case here ? Let's we call it the DC
offset, can't we remove it by taking the mean of the raw data and then
subtracting the values
localDSP, you suggested removing the DC componet from the signal and
then apply fft on it. How do I extract the DC component from the
signal without affecting it.
How would I excatly know this is my DC value and then
edit my random data according to it. Your suggestion would be well
appreciated.

I really appreciate you taking the time to answer my questions,
localDSP. Too bad, I have to go with this nick.
Why do you say "But overall there is not much signal left once you
remove your DC and eventually the very low frequency signal". DC just
brings a shift to the analog signal, and it shoul

Window Type : Hanning. Hope you could hint me on this soon.

I am tyring to produce a power spectrum graph for a Tachogram data,
related to Heart Rate Variability Analysis. This data can be thought
to be as a random signal, but has a frequency spectrum range of 0 -
1HZ.
The problem that I am facing is, I am getting very high values for
very low frequency reg
what is the power spectrum unit for Unevenly Sampled Signal
Spectrum.vi if the input signal unit is Volts?
The Unevenly Sampled Signal Spectrum.vi has two outputs, Power
Spectrum FFT(X) and Power Spectrum FFT(X) Frequency. Can anyone tell
me what's the unit for Power Spectrum FFT(X) if the input s
I don't quite get you Dennis. The listbox is 2D array type, how could
you assign a 1-D value to the Item Names ?
Let me explain the problem here. When I first load the front panel I
want an empty listbox with first row highlighted. And let's the
columns have the field info. I muxt be able to enter
