Combine two channels on one graph

I need to add a second channel, coming from same instrument, to the existing acq&graph Voltage VI (see attachment). I want to get two voltage curves on the same amplitude vs time graph. I configured the second channel and created a task, which also works on a that single channelled VI. Thanks a lot in advance

I have two tasks for each channel. So Im trying to feed those two tasks through one loop and onto a graph. I do have a task named "ai cont multi" in NI-DAQmx Base Config Unility where I can choose two channels, but when I input this task into my VI, it doesn't recognize the resource which is weird cuz It does recognizes single channeled tasks that I created. I think Im missing something fundamental on the block diagram...

  • SAP XI - Combine Two files as one in File Adapter

    Experts,
    I want to combine two files as one in File adapter itself.  I am using a simple scenario of File-to-File where i am just sending the file from sender to receiver as it is , EXCEPT, i want to add one line at the end of the file .
    I was thinking of doing this in File adapter , avoiding any mapping program in Integration Repository ..
    ANY INDEA's ??
    Regards,
    Ashutosh

    Hey
    You have 3 options,first one can be to execute a OS command before message processing or use adapter modules to append the new line in the sender adapter.
    the second option(and better one) is to do this via message mapping.
    third option is to write a OS script and execute it after message processing on receiver file adapter.
    one thing you need to make sure is that since OS scripts run on XI server itself(not on FTP server) so in case you are picking file from FTP server and delivering to FTP ,then you can't use option 1 or 3,you can only use option 2
    Thanx

  • How do I combine two regents into one in Logic Pro Arrange?

    how do I combine two regents into one in Logic Pro Arrange?

    Thanks for your input kcstudio. I would still be left with 2 regions although one after the other, on one track.
    I am trying to save steps of the way I am combining the info of 2 seperate regions into one: bouncing the 2 tracks then re-importing that audio back into the project. It would save a lot of time if you could just drag one region on top of the other

  • Combining two messages into one

    Hello,
    I have a mapping issue, I have a business process in which I have to combine two messages into one.
    To do so, I have defined a message mapping in which there are two source message types, and one target message type.
    When testing the message mapping in the IR, it works fine, but when I define and test an interface mapping with that same message mapping, I receive this error message:
    "Cannot produce target element /ns0:Messages/ns0Message1/MY_IDOC_TYPE/MY_SEGMENT. Check xml instance is valid for source xsd and target-field mapping fulfills requirements of target xsd."
    What am I doing wrong ?
    How am I supposed to combine two messages into one ?
    Thanks,
    Elad.

    Hi Elad,
    Just see if you have included both you source message interfaces and one target nessage interface correctly in while doing your interface mapping.....
    The most common mistake made when we do scenarios which include combination of two source message types into one target type are:
    - we forget to include both the source message interfaces.
    - or we interchange between one of the source message interface with the target.
    Just see if either of the 2 is aplicable in your case and just activate all components as and when you create them..

  • Hao to display two lines in one Graph

    Hi, I want to display two lines in one graph in different color , what should I do? Thanks.

    Hello Carlos,
    the help window for a waveform graph/chart only mentions "single plot
    with waveform datatype". To get more plots on one graph you have to
    build an 2D-array  of  points. Just look at the help window!

  • How can I draw two matrixes in one graph???

    I have to draw two matrixes in one graph.
    Matrix size is 10 X 100, 10 X 100.
    Help me!
    Have a good day!

    You can do this by adding multiple plots to the graph's plots collection and then plotting each matrix on its own plot. The easiest way to add additinal plots to a graph's plots collection is to right-click on the graph in the dialog editor, click on Properties, click on the Plots tab, and then click the Add button to add additional plots.
    Now if you have a member variable for the graph in your dialog class (let's call it m_graph for this example), you could do this:
    // Plot the first matrix
    m_graph.Plots.Item(1).PlotXY(/* Your first 10x100 matrix data */);
    // Plot the second matrix on a different plot, but same graph
    m_graph.Plots.Item(2).PlotXY(/* Your second 10x100 matrix data */);

  • Record two channels in one signal for GB ipad

    Is it possible to record in two channels I'm GB for ipad with one input signal?
    Message was edited by: RudyDA

    If each channel is a 1D array, then use the build array function to create a 2D array and wire that to the graph. If each channel is a waveform data type, Use the build array to create a 1D array of waveforms and wire that to the graph. Look at the shipping example called Waveform Graph.

  • How to combine two albums in one ?

    Hi, I bough a new mac and with it came the fastideous task of re-adding all the albums to iTunes once again.
    Everything was going fine until I added a album which has 2 CDs 14 tracks in one CD and 5 more in a Bonus CD what happen when I added the CDs to the library was that iTunes made two different albums.
    I tried changing the info, the name of album, the name of the artist even the release year everything was equal, yet iTunes didn't combine the two albums in one as it should.
    After I selected both albums went to get info, options and in the Part of a compilation I selected Yes, which made the smaller album to disapear, the songs are in the library, but the album disappeared from the album library.
    Any suggestion ?

    Generally setting a common Album title and Album Artist will fix things.
    For deeper problems see Grouping tracks into albums.
    Closing and reopening iTunes will usually restore any album that "disappears" after an edit.

  • How to combine two photos in one without white border?

    I am trying to combine two different photos next to each other (each 10 cm * 7.5 cm) in one of 10 cm * 15 cm and save it as a jpg file. Unfortunately when I do this in the print module (custom package) I get a file with a white border. I have set up page settings to 10*15 cm without border. How can I get a combined file without a border?

  • How to calculate the phase difference between two square wave (acquired from two channel in one DAQ)

    Hello everyone ,
     I need a quickly help that as below :
    I am trying use PCI-6220 to acquired six signals from one rotation encoder (channel A, channel B,channel Z ,and their non-signals) .The encoder out signals will be square wave and 4000pulses per revolution. I set it rotation at 300rpm speed. I need show every square wave of six out channels in waveform and measure the A-B phase difference to check if the value is correct (designed value should be 90deg) .
    I have no idea how to measure or calculate the phase difference of two square wave base on synchronizate to acquire these two square wave from two channel on the PCI-6620....
    Anyone can give a idea how to calculate the phase difference with two square wave ?
    Thank a lot and Thanks again...

  • Can I combine two objects into one?

    Hi all:
    I got a problem here: I just wonder if anyone knows how to combine the informations which I grabed from a SQL database to an object I obtained from an OO database at runtime.
    I look forward to your reply and appreciate your concern!
    regards

    Thanks for you reply, but the combined two objects can not be pre-defined because it is defined at runtime, say, there are a number of objects in database, only when you select the one for combining, you know what it is!
    Cheers

  • Can Time Machine combine two HDs into one big one?

    I know Mountain Lion added the ability to use multiple HDs simultaneously (I have done this). As it stands, it just rotates among the different HDs each time it does a backup. Is there a way to have OSX combine two HDs to make a 'virtual' bigger HD?
    The reason I ask this is because my existing iMac has a 1TB internal hard drive. I have two external LaCie drives of 2 TB each that I use for Time Machine. I'm planning on getting one of the new iMacs and custom-ordering it with a 3TB internal drive. Obviously a 2TB drive won't fit, but if OSX can combine the two HDs virtually, it'll end up with a 4TB volume, right? Can it do that?

    A hardware RAID is as reliable as the hardware. I believe the LaCie product you mention is a hardware RAID. I have no opinion of its reliability, and I don't know whether you can configure it as a mirrored RAID.
    Maybe I should clarify. I see no reason to use a RAID for backup unless you need the space. If you need a 6 TB Time Machine volume, you have to use a RAID -- striped, not mirrored. For the safety of your data, regardless of the amount, you need redundant backups, not RAID. That is, you should have at least two independent backups, at least one of which is off site at all times.

  • Combine two servers to one

    Hello,
    We have the system 11.5.7:
    AppsTier on one server and the DBTier, concurrent managers and the admin on another server. There is no the load balance for the AppsTier. The load balance requests more than one server. So we are on the Single Node architecture and Not the Multinode architecture, though there are two servers (one for AppsTier and one for DBTier and etc) in the system.
    The system has been in production about 3 years. There has never been over loaded due to the user sessions in the system. I believe we should combine the system 11.5.7 on the two servers to one server. We have the server can handle the load with significant free margin in terms of the server resources, and the performance will be improved by eliminating the latencies between the servers in the current system. Another major benefit is that the simplification for the maintenance and the upgrade.
    I need to convince the management for consolidating the two servers to one server as described. Do you agree the proposed one server system is better than two servers for our system?
    Thanks In Advance.
    Sean

    i know it will easier to manager one node rathter than multi-node but my point of view is that you will have a complete server to server your (froms and web) and another complete server for your database and concurrent manager.
    maybe you and other users have different resones and i am intersted to know is it just becase the management of one server will be easier or are there other resons.
    one qustions please is your single server more prowerfull than the other 2 servers or not?
