Re: How do I get a print dialog window ?

Are you talking about Labview Tools here or something else ?

Re: Why am I getting very high values for the very low frequency region of a random signal?

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

How do I save a mutlitcolumn data to a text file?

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

Re: How do I get a print dialog window ?

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.

Re: How do I get a print dialog window ?

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

Re: How do I get a print dialog window ?

I want Labview functions Joe, any suggestions ?

Why am I getting very high values for the very low frequency region of a random signal?

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

How do I remove a DC component from a random signal?

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.

Why do you say not much signal will be left once the DC component is removed?

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

Re: Why am I getting very high values for the very low frequency region of a random signal?

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

Re: Why am I getting very high values for the very low frequency region of a random signal?

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

Re: How do you save data into a tab delimited text file?

Hi Joe, Thanks for the info. Do you know any site that has examples related to this task ? Please let me know. Act

How do I get a print dialog window ?

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.

Re: How do I highlight the first row in an empty listbox ?

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
