Raw time series with power spectrum

I want to generate another VI with raw time series and power spectrum. Use soundgen.vi, with a sampling frequency of 1 kHz and datasize of 2000, so that it covers 2 sec.
How do I display the raw time series data and a power spectrum of it?
Find the rest of the peaks and identify them. Why the peaks are where they are?

To start do a search in the examples that came with LV for FFT. This will show you a good cross-section of what LV has to offer in terms of analysis capabilities. The thing to remember is that you can perform this analysis on data directly from a device or post-process data that you read from a datafile. After going through the examples if you have specific questions, we'll be able to give more specific answers...

Memory leak with Power Spectrum function

Hi
I have a memory leak on my application. By observing with the "Desktop Execution Trace Toolkit", the Power Spectrum function (from NI_AALPro.lvlib) seems to have two "Reference leak".
The first one refers to the function "Open VI reference"; I got around this problem by replacing the "Open VI reference" by an "Initialize" input boolean, but I don't understand the second memory leak.
Any idea ?
Thanks...

Hi Mathilde,
Thank you for using NI Discussion Forums!
I reproduce this problem with LV2012 + Desktop Execution Trace Toolkit 2012. I will look further into this.
Are there many calls of this function in your code? Could it be a problem for you?
Thank you.

Dynamic Time Series with Planning connection?

Hi guys,
I have built some reports in HFR, with a connection to a Planning application (the architect requested so). But the only way to get the YTD function properly working is using an Essbase connection (I got an error with the Planning connection).
My question is: can reports with DTS function be built with a Planning connection? Version is 11.1.2.2.
Could you please help me?
Thanks!
Lu

Is the report showing any Planning specific content? supporting detail/ cell comments?
If not you can use an Essbase connection. However if you do so then the way metadata is presented is going to be different (if you use planning connection then the member level security will mimic what is in Planning).
You cannot use attributes with a planning connection too.

Power Spectrum Density conversion to Time Series Data

Hi,
This may seem an odd request but is there a way to convert power spectrum density data back to the time series data that generated it in the first place. I have lost the original time series data but still have the PSD and need the time series to do other analysis.
Thanks,
Rhys Williams

Hate to be the bearer of bad news, but there are an infinite number of time series that will generate a given PSD. You lose all phase information upon taking the PSD. For this reason I almost always save time domain data, or at least complex FFT values.

The SAWITH3 and SAWITH6 dimensions using time series fuctions are causing a full table scan on W_GL_BALANCE_F and W_GL_ACCOUNT_D . Though we are interested in just getting 2009/11 data; the queries generated by time series function TODATE is taking us against entire W_DAY_D data and is causing several performance issues.
W_GL_BALANCE_F table has index on GL_ACCOUNT_WID and BALANCE_DT_WID.
How can we force to use index on these columns for better performance.
Please advise us on the right approach to improve performance.

Srini Pendem

Hi Srini,
I've had quite a bit of performance issues with ToDate and Ago. I tended to create materialized views on my fact tables that would materialize those values as columns and that way I would avoid having to use the ToDate or Ago functions. Is there any chance you can implement a similar solution and bypass the time series functions entirely?
Just to check, those tables belong to BI Apps, right? If so, you can log an SR about the performance issue since it's an issue with the model that Oracle sold you.
Good luck!

Question
What goddamn dates should I enter in the planning area initialization start and end to initialize for maximum duration given the settings above?
I tried a few dozens but none is accepted. For a start I tried the same dates as in Horizon of storage bucket profile. But given the kind of error text I have I cannot decipher with tiny little mind what dates I am expected to enter in for time series creation.
Thanks
BS

Thanks Mitesh,
No its 2014
Here is what worked.
Storage Bucket Horizon
Start: 24.02.2013
End: 22.11.2014
Time Series Initialization
Start: 01.02.2013
End Date: 31.12.2014
The fiscal year variant is what I pasted above.
I thought time series can only be initialized for a subset of period in the storage bucket profile !. This is my first experience of this kind where Initialization period is larger than the storage horizon. Is this the case ? I went by the book always and this is just a chance discovery by me.
I was aware of the limitation by SAP notes on need to have one more year on either sides in fiscal year variant for it to be used for initialization and hence the range of dates I tried.
Appreciate your comments on this.
All dates in dd/mm/yyyy.
Thanks
BS

Issue with nested aggregated in time series

Hi Experts,
I have a small requiremnt using time series.
eg : (sum(current year4:Quarters bookingamt)-sum(previous year4:Quarters bookingamt))/sum(previous year4:Quarters bookingamt)
Bookingamt is My measure Name.
how do we implement above logic can please help regarding this.
Thanks,
C Mahesh

Hi Mahesh,
These functions help to obtain the data analyzed based on the time. There are two types of Time Series in OBIEE viz..
1) Ago
2) To Date
Following are the prerequisites and procedure to create time series function in OBIEE RPD.
a) Create a dimensional Hierarchy (ex: YearàQTRàMonth) and convert it to the time dimension. DC on hierarchy and check the box time dimension.
b) Define the Chronological Key. A chronological key should always be the lowest level in the table and the data in it should be in the format of 20090102 or 200109 (year, month format). DC on level (preferred/last—detail) go to KEYS tab and check chronological key.
c) Duplicate the existing column, rename and specify the formula for the column.
1) Ago: This function when specified in any column displays data that is month ago, 2 months ago depending on the specified formula. DC on new column check use logical columns and click on exp. Builder. In the left column select functions and then time series and then AGO. Then in metric go to logical tables and select metric and in level go to time dimension and select month (1 month ago) and give the period as 1(since it is 1 month ago) then transfer two new columns to presentation layer
Ex: sales: 100,200,300 à -, 100, 200 (1 month AGO).
2) To Date: This functions allows us to display the aggregated measures based on the formula specified. DC on new column check use logical columns and click on exp. Builder. In the left column select functions and then time series then select TO DATE. Select metric from logical tables (revenue) and as level go to time dimension and select year(YTD) and OK.
YTD- year to date – Displays aggregated values that is with respect to month since it is YTD. Similarly for QTD and MTD.
Ex: sales: 100,200,300 à YTD Sales: 100,300,600

Issues using two-pass with dynamic time series?

Is there any issues with using Dynamic time series [Q-T-D(May)] on a dynamic calc account which is defined as two-pass and has time balance property associated with it.
The account is defined as "Dynamic Calc"+"Two-pass"+"TB First" and it works fine, but does not fetch result when used with DTS as Q-T-D(May). But, the same seems to work fine without the two-pass calc option on.
Thanks in advance,
cheers,
revati

Hi Revati,
Yes u r right, I also tried with same scenario as you mentioned.
Y-T-D values are not fetching with Twopass,but in that case Twopass is not required because of that member already having "Dynamic calc".
so you can proceed with Dynamiccalc without twopass.

Power Spectrum with RFSA

Hi all,
I have some question about fetching power spectrum with RFSA drivers.
when i set span and resolution bandwidth as 100M and 1M respective in ni5660 Configure for Spectrum,and use ni5660 Read Averaged Power Spectrum to fetch the power spectrum,does averaged power spectrum output the 100M signal once?
if so,how can i draw the spectrum in Waveform Chart as RFSA demo show us?RFSA demo did use Waveform Chart to draw spectrum,did't it?
Thanks
Liu Yuan

Hello Liu Yuan,
If you take a look at ni5660 Power in Band example in the LabView Example Finder ( Help -> Find Examples ), you will notice it uses a Waveform Graph. The Read Averaged Power Spectrum vi is contained within a while loop which means that it will continuously output the averaged power spectrum. If you want to use the RFSA drivers, I suggest looking at the RFSA Getting Started Spectrum example in the example finder. This example only reads the spectrum once, but you could put a while loop around the read vi to get continuous spectrum output. If you have any more questions feel free to post back.
Regards,
Benjamin Cook

How to find the year ago measure with out using time series functions

Thanks
Sreedhar

Hello Madan,
Thanks for the reply.
It still doesn't consider the product into account.
My columns are as below
Prod Week End DATE Current Sales Prior Sales % Change
A 12/4/2010 100 0
A 12/11/2010 200 100
A 12/18/2010 300 200
B 12/4/2010 400 300(this value is not for prod B, i want this to b 0 aswell. But we get product A's last sale amount)
Is there any way this can be done. I have tried evaluate,MSUM.
I cannot build a time dimension as all I have is a view.

Will default macros work with Time series keyfigures???

Hi,
I wanted to update time series keyfigures using Default macros. For example, i wanted to populate safety stock in a time series keyfigure while i'm running the heuristics in background.
Whole idea of doing it is to do reporting i.e. we couldnot extract safety stock because its an auxialiary key figure.
If someone has done this on a better way, can you please share with me?
And also i wanted to know whether default macros work with time series key figures.
Any help is rewarded with pionts.
Thanks & Regards,
Jagadeesh.

Hi,
I think i'm not clear on what i have posted so let make it very clear abt my scenario.
We wanted to do reporting on SNP planning area, where we take report on
Safety stock, Stock on hand which are auxialiry key figures currently.
As we cannot extract data on auxialiry key figures, we wanted to track
those information on Time series key figures.For that, we have modified
the macros and copied the auxialiry key figures into time series key
figures. All the macros are Default macros, all the prerquisites are been set and all other macros which are supposed to run before this macro, also been set.
We are not running the bcakground jobs for this macros ( exclusively), instead we are running the heuristics in background and we assume that all the default macros will get executed once the heuristics is done i.e values in auxialiry key figures are been copied to time series key figures.
Now we found out that Times series key figures are not getting updated
using Default macros.
Nowi think i make you all clear. Somehow my questions are still not answered.
1. Without running background jobs seperately for macros, will time series key figures get updated?
Thanks & Regards,
Jagadeesh.

Use of time series functions with horizontally fragmented fact tables

Hi Guys,
in OBIEE 10g it wasn't possible to use time series functions [AGO, TO_DATE] on horizontally fragmented fact tables. This was due to be fixed in 11g.
Has this been fixed? Has somebody used this new functionality? What the the limitations?

Hello,
Can you give us some examples for "horizontally fragmented fact tables", we can tell you whether we can do that or not?
Thanks,

Problem with time series functions against Essbase

Hello all,
I'm having problems with displaying correct results when using AGO function in OBIEE. I'm using Essbase 9.3.1 and OBIEE 10.1.3.4.1. Logical column named MAGO1 is created in repository like this: IFNULL( AGO("Measure01", Time.Month, 1), 0). In Answers when I use columns Measure01,MAGO1,Time.Month with filter just on Time.Month column results are OK. When I put another filter, for example Dim1.Gen2,Dim1, MAGO1 returns zero as a result. But when I put Dim1.Gen2,Dim1 also as a column and as a filter results are OK. I don't want to have Dim1.Gen2,Dim1 as a column but just in a filter. Also hiding column is not an option. I want to have grouped results and not multiple rows for one month if I remove filter Dim1.Gen2,Dim1. Filter is selected on prompt in dashboard and can be some value from Dim1.Gen2,Dim1 or All Choices. Reason for this is that I'm using this answers report as a data source for BI Publisher so additional formatting on answers report isn't helpful.
I am suspecting that something is wrong with hierarchy it time dimension or other dimensions. Or maybe MDX is not generated right ? If you need more details regarding my repository or configuration please feel free to ask. Any help is greatly appreciated.
Thanks,
D.

I am using BI Publisher and Answers report as data source. Making changes like hiding column or displaying results as pivot table won't help in this case.
Anyway I did discover something else. When I put in report logical columns with ago function they return correct results. But when I add additional logical column with todate function all logical columns with ago and todate function return zero as a result. Also this happens only when result is more than one row. If you have only one row, for example grand total level of dimension, than result is OK, but if you have more rows on a lower level than zero values appear.
Some columns that are used in filter do not appear as columns in report. This is the main problem. If I put all columns that are filtered in report than the result is OK. But I don't want to do this because I want to have option to select values on dashboard prompt on different levels.
Hope this narrows the problem.
Thanks,
D.

Fragementation with Time series calculation

Hi,
I have three 3 tables
Table1 for Region 1 , Frag Logic =Region = Region 1
Table 2 for Region 2 Frag Logic =Region = Region 2
Table 3 for Region 3 Frag Logic =Region = Region 3
we use fragementation to query based on the region.Now i have duplicated Table 1 to calculate the Previous date for time series
Table1 for Region 1 , Frag Logic =Region = Region 1
Table1 for Region 1 Prev ?
Table 2 for Region 2 Frag Logic =Region = Region 2
Table 2 for Region 2 Prev ?
Table 3 for Region 3 Frag Logic =Region = Region 3
Table 3 for Region 3 Prev ?
After adding prev tables i am almost lost,Do i need to add the Fragmentation for Prev tables also ,else we dont need as main and Prev tables are created as Alias from the base tables.Please share your thoughts.
