Can't get a dynamic data type and wire (waveform double) to both display on a waveform graph

Hi,
I'm teaching myself LabVIEW. I wish to delay a wave form and display it with the non delayed wave form. I used a delay from the examples. The output of the delay is wire (waveform double). The Simulate signal output is dynamic data. My conversion from wire (waveform double) to dynamic does not display on the waveform graph. The VI is attached. Can anyone offer any comment.

It is displaying just fine.  The display is hidden behind the display of the second signal. Expand the Plot Legend to show all three plots. Then toggle the plot visible property of the second and third plots.

  • Get image of Data Type of wire

    Hello, 
    I know how to return the image of a front panel or diagram using VI server however I'm looking to be able to return the same image as displayed within the 'Data Type of Wire' information in the Context Help window when I hover my mouse over a wire. I thought this may be achieveable by returning a reference wire to a Front Panel Control and then maniulpate the methods/properties of that to try and return it but I can't find anything that will do the job. . .
    Im asking because I have an object that stores another set of differenet objects and hovering over the highest most class returns a good diagram to show all of the data memebers within the system.
    Any ideas on how to get programatic access to that image?
    Cheers
    Tom 

    I think you guys missed the point of the original poster.
    When you hover over an LVclass wire, you see the content of the class cluster in the context help window. If the class includes other instances of other classes in its cluster, those classes are also displayed in the context help window.
    Tom wants to get that picture. The problem is that what you're seeing is not a preset picture. It's probably a tree which is dynamically generated when you hover over the wire and is probably done in the C code with no visible interface in LabVIEW (definitely not a public one).
    I can think of a couple of option:
    1. The easy one is probably to programmatically open the CH window, position the mouse over a wire of your class (will require some access to private properties. Look at LAVA forums scripting forum to see how you can access these), and then capture the entire screen and cut out the part of the image which has the CH window.
    2. The somewhat harder one is to rebuild this yourself. There's a class API in the LAVA forums code repository which should return the structure of the class. You can use that to recursively parse the cluster and build a tree of all the elements.
    Why do you want to do this?

  • How do I Change the plot waveform colour on a Dynamic Data type Graph?

    I have multiple different plots on different graphs, and I want to set the colours of the different waveforms.
    In order to display the waveforms on different graphs, I switched to Dynamic data type and then split the wire
    according to how many channels I have.
    I can set the graph background colour with a property node, and create cursors of different colours no problem
    using the array of references that I have created, so there is nothing wrong with my array of references or the property node.
    As soon as I try and wire a colour box into the Plot>Plot Colour control, I get error 1055 out of the property node.
    I was wondering if it was an error between the keyboard and the chair, but now I am thinking it is someting more sinister.
    The Error box pops up and can't be dismissed remaining the focus until I run TASKKILL on LabVIEW and terminate it.
    Any ideas on how to achieve my goal would be appreciated.

    Your web pages on MobileMe have been deleted. If you were using iWeb you wouldn't have been able to open them anyway.
    As long as you have the iWeb 'Domain' file in your user Library, or whatever the program you are using stores the information in, on your Mac you can publish to another hosting service - there are plenty to choose from. More information here:

    Apple does not repair devices beyond replacing the screen on some models or a battery replacement.  They replace the ENTIRE device.
    For the Out of Warranty replacement cost, you could have gotten a fully functional replacement device.  Instead you chose to spend less to get only the screen replaced and continue to live with additional issues.
    Apple will not touch the device now.  They will know that it was opened elsewhere and that the replacement screen is not original.

  • Can we set the dynamic data source when using getReportParameters() ?

    Hello!
    I have a report where one of its parameters refers to a list of values (LOVs). This list of values is an SQL Query type. When the data source used in the report is defined in the BI Publisher server, I'm able to get the report parameters using the getReportParameters() function in my application. However, if the data source is not defined the function throws an exception, which is understandable.
    I decided to dynamically set the data source so that even if the data source used by the report is not defined in the BI Publisher server, it still will be able to get the LOVs for the parameter. I tried setting the JDBCDataSource of the dynamicDataSource for the ReportRequest object that I passed to the getReportParameters() function. Please see the sample code below:
    reportRequest.dynamicDataSource = new BIP10.BIPDataSource();
    reportRequest.dynamicDataSource.JDBCDataSource = new BIP10.JDBCDataSource();
    setReportDataSource(reportRequest.dynamicDataSource.JDBCDataSource, connectstr, jdbc, dc); //function to set the values for JDBCDataSource object
    reportParams = webrs.getReportParameters(reportRequest, uid, pwd); //call the getReportParameters
    I was expecting this to work as this is what I did to dynamically set the data source before calling the runReport function. So, my question is -- can we set the dynamic data source when using getReportParameters() ? I tried this both in versions 10g and 11g. It does not seem to work on both versions.

    report_id column of apex_application_page_ir_rpt can help us uniquely identify each saved report.
    We can assign this report_id value to a page item and this page item can be put in the Report ID Item text box of the Advanced section of the Report Attributes page of the IR.
    This should load the saved report identified by report_id and you can get rid of javascript

  • How to add dynamic data type as one of the terminals of a Custom VI

    Hello,
    Can anybody tell me if it's possible and how to add a dynamic data type as one of the terminals of a sub-VI? I would like to have a terminal that I can connect signal from DAQmx to my sub-VI.  Thanks.

    Here is one of the coolest things about LV, and one of its major advantages over languages like VB - it has automatic memory management and it compiles whenever you make a change. This allows you to be very free in the way you handle data and change your code. In this case, you should note the small gray dot that appears when you wire the dynamic data into the Array of Waveforms input. This gray dot means that LV coerces the source data type (DDT, in this case) to the target data type (Array of waveforms). If it wouldn't match, you would get a broken wire, the VI couldn't run, and if you hover over the wire or press the broken run button you would get an exact description of the error. Cool, eh?
    This can also be seen in other things. For example, you can change an array's data type or number of dimensions by simply doing it. This will automatically be reflected anywhere the array is called in the program, and if anything won't match, the VI will be broken. If you change the # of dimensions of an array, any array function which that array is wired to will adapt. This allows you to be very safe in the way you write code, because you have LV watching all that annoying stuff for you. You don't have to worry about misspelling a variable here (for the most part).
    One important point about coercion - it does take processor power. This will usually only be evident in large arrays or loops, but it is an important point. Another thing is that coercing numeric types can cause you to lose data - coercing a DBL to a U16, for example, will cause you to lose all the fractional data.
    To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here and here are a couple you can start with. You can also contact your local NI office and join one of their courses.
    In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).

  • Difference b/w DATA TYPE and DATA OBJECT & differences b/w TYPE and LIKE

    hai
    can any one say the differences between Data type and Data Object.
    And also differences between TYPE and LIKE
    thanks
    Gani

    hi,
    _Data Types and Data Objects_
          Programs work with local program data – that is, with byte sequences in the working memory. Byte sequences that belong together are called fields and are characterized by a length, an identity (name), and – as a further attribute – by a data type. All programming languages have a concept that describes how the contents of a field are interpreted according to the data type.
          In the ABAP type concept, fields are called data objects. Each data object is thus an instance of an abstract data type. There are separate name spaces for data objects and data types. This means that a name can be the name of a data object as well as the name of a data type simultaneously.
    Data Types
       As well as occurring as attributes of a data object, data types can also be defined independently. You can then use them later on in conjunction with a data object. The definition of a user-defined data type is based on a set of predefined elementary data types. You can define data types either locally in the declaration part of a program using the TYPESstatement) or globally in the ABAP Dictionary. You can use your own data types to declare data objects or to check the types of parameters in generic operations.
         All programming languages distinguish between various types of data with various uses, such as ….. type data for storing or displaying values and numerical data for calculations. The attributes in question are described using data types. You can define, for example, how data is stored in the repository, and how the ABAP statements work with the data.
    Data types can be divided into elementary, reference, and complex types.
    a. Elementary Types
    These are data types of fixed or variable length that are not made up of other types.
    The difference between variable length data types and fixed length data types is that the length and the memory space required by data objects of variable length data types can change dynamically during runtime, and that these data types cannot be defined irreversibly while the data object is being declared.
    Predefined and User-Defined Elementary Data Types
    You can also define your own elementary data types in ABAP using the TYPES statement. You base these on the predefined data types. This determines all of the technical attributes of the new data type. For example, you could define a data type P_2 with two decimal places, based on the predefined data type P. You could then use this new type in your data declarations.
    b.  Reference Types
    Reference types are deep data types that describe reference variables, that is, data objects that contain references. A reference variable can be defined as a component of a complex data object such as a structure or internal table as well as a single field.
    c. Complex Data Types
    Complex data types are made up of other data types. A distinction is made here between structured types and table types.
    Data Objects
          Data objects are the physical units with which ABAP statements work at runtime. The contents of a data object occupy memory space in the program. ABAP statements access these contents by addressing the name of the data object and interpret them according to the data type.. For example, statements can write the contents of data objects in lists or in the database, they can pass them to and receive them from routines, they can change them by assigning new values, and they can compare them in logical expressions.
           Each ABAP data object has a set of technical attributes, which are fully defined at all times when an ABAP program is running (field length, number of decimal places, and data type). You declare data objects either statically in the declaration part of an ABAP program (the most important statement for this is DATA), or dynamically at runtime (for example, when you call procedures). As well as fields in the memory area of the program, the program also treats literals like data objects.
            A data object is a part of the repository whose content can be addressed and interpreted by the program. All data objects must be declared in the ABAP program and are not persistent, meaning that they only exist while the program is being executed. Before you can process persistent data (such as data from a database table or from a sequential file), you must read it into data objects first. Conversely, if you want to retain the contents of a data object beyond the end of the program, you must save it in a persistent form.
    Declaring Data Objects
          Apart from the interface parameters of procedures, you declare all of the data objects in an ABAP program or procedure in its declaration part. These declarative statements establish the data type of the object, along with any missing technical attributes. This takes place before the program is actually executed. The technical attributes can then be queried while the program is running.
         The interface parameters of procedures are generated as local data objects, but only when the procedure is actually called. You can define the technical attributes of the interface parameters in the procedure itself. If you do not, they adopt the attributes of the parameters from which they receive their values.
    ABAP contains the following kinds of data objects:
    a.  Literals
    Literals are not created by declarative statements. Instead, they exist in the program source code. Like all data objects, they have fixed technical attributes (field length, number of decimal places, data type), but no name. They are therefore referred to as unnamed data objects.
    b.  Named Data Objects
    Data objects that have a name that you can use to address the ABAP program are known as named objects. These can be objects of various types, including text symbols, variables and constants.
    Text symbols are pointers to texts in the text pool of the ABAP program. When the program starts, the corresponding data objects are generated from the texts stored in the text pool. They can be addressed using the name of the text symbol.
    Variables are data objects whose contents can be changed using ABAP statements. You declare variables using the DATA, CLASS-DATA, STATICS, PARAMETERS, SELECT-OPTIONS, and RANGESstatements.
    Constants are data objects whose contents cannot be changed. You declare constants using the CONSTANTSstatement.
    c.  Anonymous Data  Objects
    Data objects that cannot be addressed using a name are known as anonymous data objects. They are created using the CREATE DATAstatement and can be addressed using reference variables.
    d.  System-Defined Data Objects
    System-defined data objects do not have to be declared explicitly - they are always available at runtime.
    e.  Interface Work Areas
    Interface work areas are special variables that serve as interfaces between programs, screens, and logical databases. You declare interface work areas using the TABLES and NODESstatements.
    What is the difference between Type and Like?
    Answer1:
    TYPE, you assign datatype directly to the data object while declaring.
    LIKE,you assign the datatype of another object to the declaring data object. The datatype is referenced indirectly.
    Answer2:
    Type is a keyword used to refer to a data type whereas Like is a keyword used to copy the existing properties of already existing data object.
    Answer3:
    type refers the existing data type
    like refers the existing data object

  • How do you save dynamic data type, from the DAQ assistant, for use in Excel or matlab?

    Currently, I have the following basic VI setup to save Data from my PCI6221 Data Aquisition Card.  The problem I'm having is I keep getting the last iteration of the while loop in the measurement file and that's pretty much it.  When I try to index the data leaving the loop it gives me a 2D array of Data which cannot be input into the "Write to Measurement File" VI.  How would I save this to a useful Data/time step format?  I was wondering of a way to continuously collect the Data and then save it in a large measurement file that I would manipulate in Matlab/excel?  Am I using the wrong type of loop for this application?  I also noticed my Dynamic Data array consists of data, time, timestep and then a vector of the data taken.  Is it possible to just get a vector of the time change per sample alongside the data?    Sorry for the barrage of questions but any help would be greatly appreciated, and thanks in advance!

    There is a VI in the Express > Signal Manipulation palette called "From DDT" that lets you convert from the Dynamic Data Type to other data types that are more compatible with operations like File I/O....for instance, you could convert your DDT into a 2D array and use the Write To Spreadsheet File.vi.  Just a thought...

    Concept i know clearly.. but unable to explain it..
    Regards,
    Prasanna

    Data consists of strings of bytes in the memory area of the program. A string of related bytes is called a field. Each field has an identity (a name) and a data type. All programming languages have a concept that describes how the contents of a field are interpreted according to the data type.
             In the ABAP type concept, fields are called data objects. Each data object is an instance of an abstract data type. Data types in ABAP are not just attributes of fields, but can be defined in their own right. There are separate name spaces for data objects and data types.
