Implementation of linear fit between two cursors

Hi,
I am trying to implement a linear fit between two cursors, as I am using total of 4 cursors. I would like to implement linear fit between cursor 2&3. Please help me how to implement it and to find a slope. I am also attaching my code.
With Regards

Hi koen,
Now I would like to merge both graphs i.e., Bestfit and XY Graph (in the block diagram). Can you suggest me, I have tried with build array and concenate Inputs function, but no use. Dont mine as I am new to Labview. Thanks in advance.
First, get rid of the Express XYGraph subVIs and use the "real" XY graph VIs. The Express ones get you going faster for simple things, but your options are limited.
Take your X and Y arrays for both your original points and the best fit points (just two points, right?) and combine them into clusters of arrays (instead of feeding them into the XY graph). Then combine these into an array and feed it into your graph. It's all outlined in the XY Graph section of the LabVIEW help file.
The LV Help File is your friend, learn to use it. It gets lonely if you don't look in on it once in a while.

Linear fit between two cursors from a signal from a NI-instruments via DAQ-Assistant

Hi !
I'm currently having som problem with my labview code. I'm trying to make regression on a specific part of my graph. The graph consist of a signal gathered from a NI cDAQ-9178. Currently I can get the live data in a graph (Raw Signal) and then "zoom in" to the part of the graph that im intrested in by two cursors and then display the results in a new graph (Adjusted Signal). Now a want to make regresion in the new graph. How can i do this the best way ?
To be noted I'm a beginner of labview so my code maybe a bit off.
Best regards Maurlind

Hi maurlind,
I got it, the function that derived the linear fit couldn't handle that large numbers on the x-axis. I edited the VI so that the large number is suctracted for the fit, i.e. the array will now begin at zero time for the fit. It will not affect your plots though, only the algorithm .
Try it now with the files I provided. The file "pm_mod2_Rawsignal test.vi" should be used with "test3.lvm" (your data). The file "pm_mod3_Rawsignal test.vi" is the same as "pm_mod2_Rawsignal test.vi", but it is arranged to work with the simulated data. The file "test3.lvm" is your data, but the file is slightly edited to work on my system.
Edit "pm_mod3_Rawsignal test.vi" to fit with your acquired signal as you did with the first file you got from me.

How can I get extract the data between two cursors on an XY graph

How can I get extract the data between two cursors on an XY graph

Well, you say xy graph, so this might be a more complicated problem.
For a waveform graph it's trivial. Simply get the two cursor indices (property: cursor index) and apply them to array subset of the data. Is that all you need?
Here's how the above code would look like. using cursor.index instead of cursor.x elimnates the need to include scaling information.
For an xy graph, there could be multiple segments (e.g. imagine a spiral that passes the desired x range multiple times from both sides). This would neeed significantly more code for a general solution.

How to implement Master - Detail relation between two table views in OBI11g

Hi Gurus,
I was able to create master- detail between table and graph.
But between two tables not.
I put the listening column on the table prompt and specified channel for the Listen to Master-Detail Events in the table properties.
But did not work.
Where is the mistake?
I"d appreciate any ideas, help!
Thanks
Laszlo

Thanks for the link!
My question is :
Are the same thinga the page edge and table prompt for the tables?
If not how to add a column to the page edge (not to the table prompt)?
Thanks

Linear search between two arrays

I'm having trouble with the comparison of an array of football teams and an array of team names that may or may not be in the football team array. I have read both .txt files into their own arrays and parsed the team array with substring in order to isolate the team name. I know I can read both the search array and the team names individually because I tested it with a println. I think my problem is in the comparison "if" statement.
 public void seqSearch()//Sequential(linear) search
 int j=0, s;
 //int m = j+1;
 for(s=0; s<searchSize; s++)//increments through the search array
 for(j=0; j<teamArray.length; j++)//increments through the team array
 if(teamArray[j].getName().equals(search[s]))//I think this is where the problem is
 System.out.println("Found " + teamArray[j].getName() + "after" + j + "searches.");
 break;
 else
 System.out.println(teamArray[j].getName());//prints through all of the names during each search for testing
 if(j == teamArray.length-1)
 System.out.println("Can't find " + search[s] + " after " + j + " searches");
 }//end for
 }//end seqSearch()My output prints the names of each team on their own line and at the end it always says that it can't find each search term.
Ex.
Bears
Bengals
Bills
Vikings
Can't find Bills after 32 searches
Bears
Bengals
Bills
Vikings
Can't find Eagles after 32 searches
etc
I though that .equals was the way to compare in this situation. Any idea what I'm doing wrong?

Dave,
teamArray[j].getName().equals(search[s]))what is the implementation class which is returned from "search[s]" and from "eamArray[j].getName()"
if both of them are java.lang.String then us "equalsIgnoreCase" instead of "equals"
if the implementation class is different, then you have to override the equal method and implement your own.

Drag and Drop between two windows

I would like to implement Drag and Drop between two windows for example in Windows I can take URL Address form browser and drag it and drop it in to any control that excepts String like TextField.
I would like to have the same behavior with my Java Text Controls.
What can I do to achieve this?

There is no configuration for it. It should work.
Can you try it in a different user account. If it works in a different account, then it is likely something in your current user account that is messed up. If it doesn't work in another user account, then it is likely something with Mail, itself.
You could try downloading and installing the 10.6.7 combo update. That may repair what is wrong.

Drag and Drop between two JTables

I tried to implement drag and drop between two JTables using data transfer, but i did not get it to work, that dnd works in both directions. i have my own transferhandler, but if is use setTransferHandler(handler), i'm no longer able to start a drag from that table. i also tried to use a mouse listener to call exportAsDrag, but i only works in one direction. any ideas or examples?

That is a rather large request, and indicates that you have likely not spent much time researching the subject before posting. Read up on Swing drag & drop here (http://java.sun.com/docs/books/tutorial/dnd/), then ask specific questions about something you don't understand, problems with your implementation, etc.

How to transfer parameters between two iViews?

Hi all,
I have two WebDynpro based iViews (StartView and SecondView). when I press the button in the StartView, the EP will navigate to the SecondView. During this process, I want send a parameter value from the StartView to the Second View. In the StartView, I use the follow method to navigator:
WDPortalNavigation.navigateAbsolute(
 "ROLES:portal_content/com.sap.itsamtest/com.sap.secondpage",
 WDPortalNavigationMode.SHOW_INPLACE,
 (String) null,
 (String) null,
 WDPortalNavigationHistoryMode.NO_DUPLICATIONS,
 (String) null,
 (String) null,
 "value=From Start Page");
In the SecondView, I use the WDWebContextAdapter to get parameter's value.
String Name = WDWebContextAdapter.getWebContextAdapter().getRequestParameter("value");
It works fine. But I found there is a warning message:
The method getRequestParameter(String) from the type IWDWebContextAdapter is deprecated
So is there any other good mechanism to implement the data transfer between two iViews.
Thanks and Best regards
Deyang

Getting text between two tag

Hello,
what would be the best method to implement to get text between
two tags,
eg <TEST1> this is a test </TEST1>
as in; this is a test,
i try to use BreakIterator, but it skip the tags,
when i do word by word loop

this is one way:
String string = "<TEXT>This is the middle text</TEXT>";
String x = string.substring(string.indexOf("<TEXT>") + "<TEXT>".length(), string.indexOf("</TEXT>"));

Can a SQL Server Failover Cluster Instance (FCI) be Implemented Between Two Hyper-V Hosted Virtual Machines?

I haven't had the opportunity to implement a SQL Server Failover Cluster Instance (FCI) for over 10 years and that was done with two physical, identical database servers way back in the day of Windows Server 2003 and SQL Server 2000 (old school).
Can a SQL Server 2008 R2 Failover Cluster Instance (FCI) be implemented between two Hyper-V hosted virtual machines? The environment in question already has Windows Server 2012 R2 Hyper-V hosts in place, so I'm just looking to see if this is even
possible and/or supported when utilizing virtual machines.
The client in question is currently using SQL Server 2008 R2 instances running on Win2008R2, Win2012, and Win2012R2, but I'd also be interested how this can be done or not with SQL Server 2012 or 2014 as well. Thanks in advance.
Bill Thacker

Yes, it can be done with Hyper-V guests. In fact, with Windows Server 2012 R2 Hyper-V, guests can use the Shared VHDX feature for shared storage used by Windows clusters. The guests can run Windows Server 2008 and higher provided that the Hyper-V Integration
Services are installed to support Shared VHDX. The only challenge here is making the Hyper-V hosts highly available as well, running it on WSFC.

How to implement Non linear Curve fitting (lsqcurvefit of matlab) in Labview

Hi Labview Team,
I am looking a way to implement "lsqcurvefit" command of matlab in Labview to do some curve fitting ; basically to Solve nonlinear curve-fitting (data-fitting) problems in least-squares sense, at present I couldn't find a better way to implement it. Can you please give me some suggestion on this to how to implement this " curve-fitting: on labview.
Thanks,
Ankit Gupta

You did not say you have the mathscript module. Do you? In any case, labview has a rich set of native nonlinear fitting tools. This seems like a better option.
