How to perform FT on XY Graph data?

Hello,
I have my data in two 1D arrays (X and Y) and plotted in an XY Graph. I did not use a waveform because it was not a time signal, it was a spatial one with an uneven interval. Briefly, the experiment measured the output of an amplifier as the position of a mirror was varied through several millimeters. I need the fourier transform of this plot but cannot figure out how to do it in labview.
I've uploaded the raw data file which is a tab delimited txt file. If this is transposed and displayed in an XY graph you will retrieve the curve I need to FT. As the X data is on the order of 1E-10 I am expecting reciprocal space, X', to be on the order of 1E+10.
Please help, I have been playing about with FFT.vi and signal processing VI's all day and cannot seem to get anywhere.

FFT assumes that your data is equally spaced in X, but you said that you have uneven intervals (if I understand you right).
There is a tool for unevenly sampled data: Unevenly Sampled Signal Spectrum VI
You could also resample your data into a even grid using interpolation.
A waveform graph does not imply time data, you can call the axis anything you want. The only requirement is that the data has a constant x-increment. If it does, you can di a plain FFT on the Y array and calculate df from dx and N.
EDIT: looking at your data: for all practical purpose it is sampled equally in time, the differences are due to the limited decimal resolution. the delta is randomly either 3.3E-14 or 3.4E-14, depending on where you look. You could just use an average delta.

Here's a quick example I threw together that generates a sort-of-bell-curve shaped data distribution, then performs the binning and plotting.

How to perform calculations using column data in BI Publisher

Hello guys
I am very new to BIP, and recently I am learning to create new templates using XML files..
I am trying to create a report that has Account Amount, Amount Net Amount, PM_Amount and a New field say "X"
For Account Amount it is what it is, but for Net Amount it is "Account Amount/40%", for PM_Amount it is "Net Amount x (Account Amount/30)" and for field X it is "(Net Amount + PM_Amount)/column A" where column A is another data field in the XML file but it should not be included in the template report..
Could anyone help me with how to perform such kind of calculations in BIP Template builder? In OBIEE, it is very easy that I can just use column formula, but in BIP I still haven't figure out the way yet..
PLease advice
Thanks

Thanks for the reply..
I looked at the link you provided already, what I wanna know is how to exactly apply the expression in my calculation. In other words, I know that Column C = "Column A div Column B", but in BIP form property, how do I actually substitue "column A" with the actual column..
I wish I could post the XML, but it is huge, it contains 6 data sets and more than 100 columns. I only need 15 columns on my template.
On the form property of each measures, in the "advance tab", I see codes like <?accountamount?>. Now I wanna have a new column said "PM_Amt" which should be "(accountamount div %40) x column B". So I just randomly select another column said "payment". I rename it to "PM_AMT" and on its "advanced tab" it is still <?payment?>. So right there, if I wanna replace that code with a new one that does "(accountamount div %40) x column B" calculation, how would I do it? What would be the syntax including how to propertly refer to the right column field as part of the expression?
And do I have to always use xdofx between <>? how would I know?
Please advice if you understood what I am trying to say
Much thanks

How to have a web-based interface for Lumira that also performs Ad-Hoc visualizations on data that should be loaded live from HANA.

How to have a web-based interface for Lumira that also performs Ad-Hoc visualizations on data that should be loaded live from HANA. I have another tool that puts data into HANA, So don't want to reload this new data into Lumira every time I want to run a report.
so do i have the ability to create polished ad hoc dashboards, reports, infographics and storyboards Apart from Ad-Hoc reports, I also need a dashboard with some fixed reports that update with the live data.
So please suggest me to accomplish this task.
Thanks and regards

How do I write a vi that will save graph data and text data (related to the graph) so the next time I want to view the graph data the text data is included in the read vi?

I am new at writing vi's and hope you may be able to help. I would like to create a vi that will graph measurements taken from a daq device. I would like to include text data that a user can choose from (example: machine number, test circuit, load cell type) that will stay with the graph so when the graph is viewed at a later time the text data (explaining parts of the graph) will display with the graph data. I have included a vi I am using to capture and display a force value. Any help would be greatly appreicated.

What you want is a DATALOG file:
When you save a file, use the BUNDLE function to bundle your machine number, test circuit, whatever (include a few spare fields), plus your graph data. Get the graph data from the source, or use a local variable of the graph itself.
Wire the bundle output to the DATALOG TYPE of a NEW FILE function. (I presume you'll use a FILE DIALOG set to SAVE FILE to choose a file path).
Write the same bundle output to the DATA input of a WRITE FILE function.
Use a CLOSE FILE function to (ahem) close the file.
When you want to read a file, use a FILE DIALOG set to EXISTING FILE (or some other means) to specify what file to read. Wire the same cluster type to the DATALOG TYPE of the FILE DIALOG, so that it will only
offer files of the correct type.
When you have a file path chosen, wire the bundle to the DATALOG TYPE input of a FILE OPEN operation.
Use a FILE READ to read a single cluster - the output of FILE READ will be a cluster of the right type.
Use a CLOSE FILE function to....
Out of the FILE READ function, you can UNBUNDLE BY NAME the data and send to the graph and the other fields, or, if you're clever, you can use a cluster on the screen, and not unbundle it. That's harder though, since you probably want the text fields to be controls (inputs) and the graph to be an indicator (output).
Hope that helps.

How can I modify the High Speed Data Reader VI to show correct time information in x-axis?

I am just a beginner learning the LabVIEW programming currently.
I have a PXI 6115 DAQ card and have to make a hardware timed acquisition VI for maximum performance. Thus I use the High Speed Data Logger VI for data acquisition.
However, when I read my data by using the High Speed Data Reader VI, it doesn't show its correct time information in the graph.
How can I modify the High Speed Data Reader VI to show correct time information in x-axis?
I hope you can explain easily because I am a beginner.

Hey Chunrok,
I've modified the High Speed Data Reader VI slightly so that it now uses the scan rate of the data (as determined from the file) to set the scaling for the data points. If you wanted the start time to be a specific time you could use the start time obtained from your file to set the xscale offset as well.
I hope this helps!

Format the x axis to either absoulte or relative time.
You can do this by right clickingo n the graph and selecting x axis then formatting from the menu.

First, I couldn't seem to find that example either on computer or on the NI sites.
The problem that we're running into is stated in the article that I pointed to - when real time VIs are running, then the OS will stop updating the OS clock. TO us it looks like the clock is losing time. There is a hardware clock on the PXI and it is read only during boot up to set the OS clock. Our discussions with NI have not led to a solution for this problem without checking the time on start and then checking the tick count (which does not lose time) and calculating what the current time is. No access to the hardware clock is supplied.
We're still working on a simpler way to get accurate time.

the first MTI record should be the source record ...ie. it should have transaction quantity as negative.
new set of MTI records should have positive transaction quantities.
Also ensure that sum of transaction quantities for the set should be 0...
What is the error that you are getting?
Thanks,

How do I make an XY-Graph plot points over time?

I am building a program to plot and take data of a relationship between two voltages. One is voltage is uniquely dependent on the other. So far I have successfully built an XY-Graph to plot the voltages against each other (Voltage1 along the x-axis and Voltage2 along the y-axis). However, the XY-Graph only diplays the point (V1, V2) at the instantaneous time I am looking at it, and does not continuously plot different points as I vary the independent voltage. I need the graph to display all the points that occur as I vary the independent voltage. As of right now, all I see is one little cursor that moves all over the graph as I vary it. My program consists of a While Loop that contains all of the following: two seperate data anolog input functions that take both voltage separately from my board. The the output samples from each 'AI Sample' function are then bundled into one cluster using the 'bundle' function. The cluster output from the 'bundle' function is then wired to a 'build array' function. The 1-D array output from the 'build array' function is then wired to my 'XY-Graph'. How do I get the XY-Graph to plot a point every millisecond or so?

Bundling and then using the Build Array is not correct. Yuo can see the correct method in the help for an XY Graph below. In order to use the normal XY Grpah, you would have two shif registers. One for the X array and one for the Y. Bundle the two arrays and then wire to the graph.
The other way is to use the Express XY Graph. With that, you can just wire your scalars to the X and Y inputs and set the Reset input to false.

Graph Data Labels in OBIEE 11g - Customizing

Hi folks!
Would somebody know how to select what is shown in graph data labels in OBIEE 11g?
For example in a scatter graph data label I'd like to show the Group only (not the combination of Series, Group, X and Y, as by default). For a pie chart one can select the data shown in data labels to some extent (name / value), however couldn't find this option for scatter graph.
After searching I could only find instructions for 10g - such as John's instructions at http://obiee101.blogspot.com.es/2008/01/obiee-xy-and-data-in-mouse-over-label.html.
However, my understanding is that the graph engine in OBIEE 11g is now different, and the 10g instructions are not valid for 11g anymore.
I was also having a look on the .cxml files in OBIEE 11g but those seem to relate to colors only?
Any help appreciated, best regards,
Ilmari

How to perform power spectra analysis in DIAdem

Dear all:
I am a beginner in DIAdem but I have to complete my PhD thesis that is about the
analysis of rat EEG in DIAdem. I have acquired 10G data of rat EEG. I prefer the
power spectra method. Would someone please tell me:
1. How to perform power spectra analysis of multichannel EEG(8 channels) in
DIAdem? I hope the unit of the vertical axis is microV^2, but not dB ,nor
10*log10(microV^2/Hz).
2. How to calculate the absolute power and the relative power of EEG at a certain
frequency band in DIAdem? Is it possible to do it in DIAdem?
Thank you very much
Jing
