Movement of the cursor with nod to the data nearest

I would like to have a cursor ONLY align with the closest data point for the cursor of the mouse on a XY graph when the mouse: down.

The cursor action requires dragging. Anyway to have the cursor align with nearest (closeset in Euclidean produce units) data point to the location of the mouse without slipping?

I tried to extract the coordinates of the mouse and then look for in a list of XY graph coordinates converted to pixel coordinates. It seems that mapping the coordinates of graph coordinates in pixels is incompatible with the text changes and other features outside the chart area.

Useful features

1. coordinated output XY from at least one corner of the chart (on the inside where data) area.

2. an index of the nearest data point in the graph where the mouse.

3. an option of a cursor to align with the closest point of data where the mouse and mouse: down.

No workaround (example screws) is greatly appreciated.

Just resolved. I used a snippit of code from someone, but it had misused the coordinates of the frame rather than graphic. Now I can do exactly what I was looking for. I'll post the VI after cleaning a little more.

  • Function to move all the dates for the previous Monday

    Here's what I have:

    create or replace
    FUNCTION ToPreviousMonday
    (DATE_FIELD IN date)
    Date of RETURN
    AS
    BEGIN
    IF TO_DATE (DATE_FIELD, 'DAY') = 'SUN' THEN (DATE_FIELD)-6;
    Of ANOTHER trunc (DATE_FIELD, 'd.') + 1;
    END IF;
    END ToPreviousMonday;

    Don't compile.

    Basically, what I want to accomplish is in a SELECT statement, say something like (SELECT ToPreviousMonday (MyDateField) FROM MaTable) and cause the data back as the date of the previous Monday. NLS_TERRITORY is and will be for all the sessions going to Sunday as the day of the week 1.

    Pointers?

    Use:

    TRUNC (DATE_FIELD, 'IW')

    IW means ISO week which starts always on Monday regardless of NLS.

  • Impossible to move all the data using BT to Satellite C50-A-19 t with Win 8.1

    Hello

    I have a portable Satellite C50-at-19 t, that came pre-installed with Windows 8.1.

    I cannot transfer files on any of my other Bluetooth devices paired with the laptop, but I can transfer files from laptop to other devices, it seems to work only one way.

    The PC does not display a file download, and the transmitter device says not sent the file. I looked in the Bluetooth settings but find nothing much in there. other devices work properly with each other.

    I hope someone can give me an idea of what I'm doing wrong.

    Thank you. John.

    > I'm unable to transfer files on any of my other Bluetooth devices paired with the laptop, but I can transfer files from laptop to other devices, it seems to work only one way.

    In your case, I recommend to check others like Firewall and antivirus security settings.
    I suggest you to temporary disable the antivirus and firewall and then check the result
    Perhaps BT file transfer is blocked.

  • Move the "Data Service" volume ZFS on OSX Server

    Hi all
    I would like to move all the data service to a ZFS volume on a Mavericks OSX Server. This option can be found here:
    Server.app-> your server-> settings
    and is called "Data Service". As someone has already done this? It works or what I have to do a manual config, whenever the server restarts?

    Hi all

    So I'll answer my own question.  The answer is no, in fact, the app Server does not detect even the zfs volume.  I also try to cheat and to synchronize the/Library/Server volume ZFS and softlink then the original file to the copy of the zfs volume, but App Server would no longer work.

    Then Mac OS x still don't like ZFS much.

    I reformatted the drive with appleRAID, and then I could move everything using the button in the application.  I noticed that this original file is still there.  If it's really just an arrangement written somewhere.  Anyone know where this parameter is written?  Maybe I could get data on the ZFS drive sync and write this setting by hand.

  • When refreshing a movie thumbnail 13 adobe Photoshop elements the date changes

    When updating saving the metadata file info in adobe Photoshop elements 13 organizer on a movie thumbnail the date will change to a different/wrong date. Any suggestions to get it to read the correct metadata on a movie (MOV) file.

    The problem with movie files, is that the "date taken" is not recorded by the camera in a metadata section. Therefore, the Organizer assumes "creation date" returned by the computer OS must be used. You can change (update) the "date taken" in the Organizer so that the catalog keeps information you entered in the catalogue.

  • Anyway to save the data in a loop without using shift register or feedback loop

    Hi all

    I've been thinking, is it possible to save data in a loop to the next iteration without the use of a shift register or a feedback loop?

    I need the possibility to reload the data within a loop from a file of lvm, but I want to use the same data until I have load some new.

    The reason why I don't want use the node registry or feedback shift is due to speed, although I don't know if the registry change

    in fact moves all the data of one register to another, or if it is stopped until a change data occur.

    I want to reuse data medium and large (6 measure of strength, pressure 2, 1 flow channels) of about 10 s data in each file with samplingsrate of 2 kHz...

    In my testing program, I have several CPU demanding computations and 3D graphics, so I want just to minimize the CPU loading as much as I can for each part of the

    software...

    I am enclosing a small VI to explain what I mean.

    I have now, I shouldn't use the express VI and I'll change that as well - it's just a proof of concept!

    Hope you guys can help me better understand this shift register...

    Thank you!

    -Tommy

    If the speed is the name of the game, go with the flow (data) and stick to a shift of registers or feedback node.  No data is moved, their job is to do pretty much exactly what you describe.  Any other solution, control/locals/globals will imply a copy of the data, and then you will have problems with speed.

  • Transfer data using the data engine

    HII guys,
    I installed PT8.49 on oracle10.2 on windows-2003(32-bit) and did the installation. Now, I did a production facility with PT8.51 on oracle 11 g 2 on windows-2008(64-bit). Now I have to move all the data from test or PT8.49 to PT8.51.Is it is possible to do or should I move PT8.49 to PT8.51? If possible please give me some links to blogs and other resources pls guide me what to do?


    Thank you

    You are again trying to move data between different Peopletools version, but it's rather strange, without substantive analysis. Must match tables, columns must match, but also the values defined.
    It is not that simple, and the best advice here would be to upgrade your test environment to the production level. Anyway, being on the same level that production is the best way to test before going to production.

  • My laptop is dead. How can I go on the transfer of the data to replacing it?

    My old laptop has bit the dust.  He is running, but I don't see anything on the screen.  I would like to move all the data to a newly purchased laptop, but do not know how to do in this regard.  Any help you can offer would be appreciated!

    You can remove the drive from the laptop and ride in a USB enclosure, you need a box that can mount a 2.5 drive "or you will need an adapter, see here for housing typical & adapter: http://www.tigerdirect.com/applications/category/category_slc.asp?CatId=2781&name=2.5

    Or you can network together laptops and transfer your files over the network.  Do you have a router?  If so, all you need are a couple of 'straight' cables to connect laptop computers to the router.  If you do not have a router, you need a "crossover" cable to connect two laptops together via their ethernet (network) adapters, any decent computer store half know what are these cables and which ones you need.

    anesvet,
    I'm going to sound like I'm repeating myself tonight... (see previous 4 posts...)  but try this:

    When you start start pressing F8 until you get the Windows startup options.  Then try "Last known good configuration" see if that helps.  If this does not work, try to F * then try to go to Safe Mode.  If those who do not help, I would start with your XP CD to recovery mode and run "chkdsk/r" then "sfc/scannow".  QQ learn manage!

  • When you type in Firefox, the cursor moves to the left while everything is written backwards.

    Recently, whenever I try to type so that Firefox 9.01, the cursor moves to the left while everything is written backwards. I can normally type into a word document to have done with it and cut and pasted in this message. I use Windows XP. I closed Firefox and restarted my computer twice with no success to solve this problem.
