Issue with displaying scatter plot

Hello,
In the attached Test Host TCP Read Three peaks New (Events Global).vi I am trying to display a data file in a series of scatter plots. The data is read from a functional global, then formatted based on the axis selections and displayed.
Each plot allows selecting the x and y axis from a drop down menu. I spent a lot of time troubleshooting the following software bug: Whatever I do, the program keeps displaying the old data along with the new data set(s).
The program is part of a larger application, where new data are constantly fed to the scatter plots and displayed together with the old data.
I would appreciate your assitance in troubleshooting this application. Thank you.
Best regards,
Peter

Hello Eric-E,
Thank you for your reply. This information about shift register appending data to existing data is new to me. Thus, I wrote the attached test vi. The shift register does not append the data. Rather, it replaces the data from the first loop iteration with the data from the second loop iteration, as expected. Also I have a reset function (Clear Plot.vi) in one of the loops together with a boolean (Reset Data) to trigger it. However, the old data is still not cleared.
Or did I misunderstand something?
Please advise. Thanks.
Peter

  • Issue with displaying summary in the Page Bottom

    Hi Friends,
    I have an issue with displaying summary in the page bottom. for this i am using command BOTTOM and ENDBOTTOM in Main Window.
    I designed 2 pages are First and Next, in the first it displays PO Header details and Item details in the Main window and also Item details continuious in the Next Page also.
    If the lines are enough in Bottom then it displays the summary. But if the lines are not enough in bottom then it does not trigger the new page, so that it doesn't displays the Summary in Bottom.
    for ex: Total lines of the page 50 and Bottom required 15 lines. In the next page contains upto 35 lines, it triggers the Bottom.
    But if the lines are more than 35 and below than 50, it does not trigger the new page so that it does not shows the bottom.
    Please help me on the same, this is very urgent.I will give a rewatrd if it is helful.
    Regards,

    HI,
    Try with printing the bottom data with Protect and ENDPROTECT along with your Bottom and endbottom.
    Eg: Protect
    bottom
    text
    endbottom
    endprotect.

    The first question that needs to be answered is whether the problem is a data storage problem or data presentation problem.
    The query below will answer this question.

  • Issue with displaying text in BEx

    Hi all,
    We are facing an issue with displaying text in the query output.
    We have a master data carrying charac ' 0MATERIAL'.When i do maintain master data ,I am able to see medium description in the output.
    Now when i drag 0MATERIAL in bex designer and in properties set display to key and text(medium text), it shows me only the key and it shows some wierd text which is in no way related to the medium description ( that was shown under maintain master data)
    can anyone pls tell me why i am not able to see the medium description when executing the query that too when the text is loaded.
    Pls help
    Regards,
    Suchitra

    But what i wouldlike to know is what about the master data which is present in 0MATERIAL now?
    Nothing will happen to your data.
    Its showing there ...dosent that mean its present and activated?
    They are present n in active version.
    If u change any records they will be in M version..by activating the data...u are converting it to A version.

  • Issue with display of decimal places

    Hi,
    In our custom built components we are facing a strange issue with the display decimals  where the data type of an element is "QUAN - Quantity field, points to a unit field with format UNIT".
    If the element has a value of 3000.000 KG the value is displayed as 3000. Where as for an element which has a value 3000.123 KG the same is displayed as it is with the decimals. We tried to resolve the issue by using Text editor or Input field as read only but in vain. The display property in the context are set to default.
    If we change the element data type reference to "Dec - Counter or amount field with Comma and Sign" then all the values are displayed with the decimal places even if decimals are zero.
    As a result we are facing alignment issues for the various quantity related elements displayed on the screen.  To change the underlying data type of the element is a not a solution for us as the data type quan is required for conversion from one unit to another unit.
    Can someone please advise how we could resolve this issue.  We are on NW 7.0 + EHP4 + NW 7.01 SP4, kernel patch level 55 for 7.01
    Regards
    Rohit Chowdhary

    Jameel, Thanks for the answer but this is a not a solution for us. We have around 40-50 webdynpro components and with mutliple views referring to this data element / domain combination. More so the context are bound to database tables / structures . 
    I hope to get a reply from Thomas on possible solution for this. I am not sure if I can open an support ticket for this issue.

  • RichFaces: Issue with displaying Dynamic panel

    {color:#0000ff}Hi ,
    My requirement is that, i have a page with four links. On clicking on each link, i should display a table and a textfield to filter out the table results.
    To make it generic i am generating the table and filter fields dynamically and binding to a <rich:panel>
    <rich:panel id="manageUsersPanel" styleClass="surveyPanel">
    <rich:panel binding="#{adminUsersDataBean.searchTablePanel}" />
    </rich:panel>The binding #{adminUsersDataBean.searchTablePanel} is of type HtmlPanel.
    It has two child components HtmlPanelGrid and HtmlDataTable.
    and finally rendering the panel on clicking on each link.
    Now the issue is, By the moment i click on any link and reRender the panel it is not showing up.
    If i do F5/ Ctrl + F5 i am able to see the table and other fields.
    Surprisingly if a place any richfaces tags (some <h:outputtext> /<a4j:commandButton> any code) it is coming.
    Only the dynamic binding value is not refreshing.
    Some body please help me out to sortout the issue.
    Thanks in advance.
    Thanks
    Venkat{color}

    i found solution to this problem..
    use <af:iterator>r instead of af:forEach
    bind <af:iterator> to collectionModel
    <af:iterator id="i3"
    value="#{bindings.VO_DA1.collectionModel}"
    var="ls">

  • Issue with displaying international characters returned by Search And Promote.

    Hi,
         I am trying to display international characters being returned by Search and Promote. The actual text returned by S&P is televisión, while the one being displayed is televisión
    I am usging r.get() to fetch values returned by S&P. The issue is only with data returned by S&P. Local international texts are being properly displayed.
    Thanks in advance!

    Thanks Sham! Found the fix. I am checking for invalid characters in the byte stream and then applying corresponding encoding.
    This method checks for invalid characters.
    public static boolean isValidUTF8( byte[] input ) {
        CharsetDecoder cs = Charset.forName("UTF-8").newDecoder();
        try {
            cs.decode(ByteBuffer.wrap(input));
            return true;
        catch(CharacterCodingException e){
            return false;
    This statement performs corresponding encoding.
    String utf8 = new String(inputString.getBytes(encoded format), Charset.forName("UTF-8"));

  • IMac issues with displaying Internet images

    Recently my iMac hasn't been displaying some images on the Internet correctly. For example the header of bbc.co.uk/news looks like a TV searching for a scrambled signal, but the rest of the images on the page are fine. There are a few other sites that I'm experiencing the same issue. When I try to save those images, they download with the same scrambled effect. I'm not sure what caused it to do this, but it also started on my Macbook Pro a few days after. It's not the browser because the same thing happens on Chrome, Safari and Firefox. I've tried resetting the cache and PRAM but to no success. Both computers are running OS X 10.9.
    I'm not sure how to attach a file on this forum, but here is an imgur link to a screen shot of the problem http://imgur.com/7hGFSqE.
    If anyone has seen something like this, please let me know.
    Regards,

    Please read this whole message before doing anything.
    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
    Step 1
    The purpose of this step is to determine whether the problem is localized to your user account.
    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
    While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain models.  The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

  • Issues with displaying vision in preview window in FCP

    Hello ALl,
    I need some serious help. I have had to re-install all my mac software and now I am having issues when trying to capture and log vision. I am using FCP and my camera is a Sony 1080i HVR-Z1P. It was working fine with an older version of quicktime but now that I have downloaded QT 7.3.0 is seems to be having issues.
    I can click on 'capture and log' and the preview window displays 'Preview Disabled' all features work the camera (play, rewind, fastforward) but the vision will not display.
    I called mac support and was basically fobbed off by Sean (Canadian I think he was). Last time I had this issue was due to quicktime software update and spoke with a man who sounded Switz and he was a great help giving me an older version of quicktime to resolve my issue. So far I have tried un-installing quicktime many times which hasn't helped.
    Any suggestions would be well received.
    Cheers!

    It was driving me crazy too; this solved it for me:
    You can fix this by enabling "Always show scrollbar" under "General" in "System Preferences"
    I'm bumping this old thread as it is the top hit in Google when searching for this issue.
