Using mouse to return waveformgraph coordenates

Hello !!!
I am using labview 8.0 and I would like to show the coordenates of a waveform graph in a label when the user moves the cursor into it, otherwise show nothing, is there anyway to do that ???  I would be very grateful if someone could help by sending a vi if it's possible or a pic of how to do it!!!
Thanks a lot !!!!!!

Thanks for the help, but... it would be possible without the cursor ??? just the mouse movemente ???? because in my graph I have to plot 3 different vectors ...
The example I put together displays the results for both the mouse move as well as using a cursor. If you move the mouse around on the graph the indicators on the right will update. It wasn't clear exactly what you wanted.
ps: it's also possible to renitializa (show ceros or blank) if you are not in the graph ????
Again, it's not clear what you are referring to: i.e., whether you're talking about the pixel coordinates, or the XY values, or to a specific point on the plot. For instance, if the cursor is on the plot line, but not on a specific plot point, what should the indicators display?

  • Using mouse on macbook air is unnatural and not accurate

    I have been using macbook air for web development. It seems pretty good or almost perfect when it comes to using trackpad. The only problem is when I use a mouse, it just feel unnatural and strains many hands until I give up using mouse and return to trackpad. I love the windows natural feel of using mouse and mac way of using trackpad. As far as I know, the issue is caused by peculiar acceleration curve for mouse. I hope Apple is listening to this issue and FIX it as soon as possible. It does not help when only online community is responding and not Apple. This problem is worse when it comes to gaming especially FPS game. That's why those kind of game is almost impossible on mac. I know Apple is kind of perfectionist, judging from the way the products are designed. So, don't let's this blemish the user experience of mac OS, Apple!

    I hope Apple is listening to this issue

  • HI .. I have a new macmini 2.5 Ghz 10.7.3 Lion, had a problem today ,it froze so I could not shut down using mouse or tablet. used the power switch, when I tried to restart I got audible 'beeps' from it.

    HI ....I have a new macmini 2.5 Ghz 10.7.3 Lion, had a problem today ,it froze so I could not shut down using mouse or tablet pen. used the power switch, when I tried to restart I got audible 'beeps' from it. I managed to restart it but kept getting a message come up on one ot the dual screens ' restart using the power swich to turn it off , then press it again to restart.'
    This worked okay , but now it just keeps freezing whenever I start it up. I thought the issue could be my old Epson Expression 1680 scanner not being compatible , so I have unplugged it. I also had a look at the new memory I installed when I got it, but this seems not be the problem.
    It is connected up to an Eizo Flexscan S2231W using a cable straight into the HDMI input , the other monitor is a small Acer using the VGA into Thunderbolt port.
    When I turn the Eizo screen on first and then press the power button on the mac-mini, I hear the chime then the screen flahes the 'Digital no signal' message on and off for about 30 seconds , then the monitor comes on as normal. But it is still freezing up on me after using it for a while and I am having to use the power switch button to turn it off again.
    Can anyone help please.

    I really don't have an answer for that one. I guess that while trying to get things working correctly, I would use the most basic monitor I had which in your case would be the Eizon using the Thunderbolt port and adaptor.
    When you boot into Safe Mode the startup is quite slow, but you should get the Apple logo and then the spinning gear below it (release the SHIFT key when it appears.) Then after a little more time you should see a gray progress bar appear below the spinning gear. When that disappears the computer will startup to a login screen.

  • Can I use the value returned from a Text Function in another Formula?

    I'm writing a report in Hyperion System 9 BI + Financial Reporting Studio version 9.2. I have 2 grids in my report.
    Grid1 Column A is set up as a text function using the function type - <<GetCell("Grid2", 1, a, 1)>>. I would like to use the values returned from this text function in Column A (Grid 1) in a formula in Column B (Grid 1).
    Is it possible to use the values returned in Column A of the text function in another formula? My report does not seem to recognize Column A as numerical values, even though the values to be returned are numerical.
    If so, how do I recognize the values in Column A Grid 1 as numerical values and not text?
    Thanks for any help you can offer!

    Hi Edson,
    Yes you need to use the CALC_ERROR macro function to be able to test whether the last macro function returned an error. CALC_ERROR will return an 'X' if there an error occured during the execution of the last macro function.
    You can use a macro similar to the following:
    IF
      CALC_ERROR( )
      = 'X'
          DO SOMETHING HERE
    ENDIF
    Let me explain how this works internally. The SAP system maintains a global variable g_flg_calc_error during the execution of macros in the planning book. The g_flg_calc_error variable will contain the value of f_calc_error that was set by the last macro function which executed. The ABAP coding of a planning book is something like this:
    data: g_flg_calc_error type /SAPAPO/FLAG.
    * SAP will pass g_flg_calc_error variable to all macro
    * functions. When SAP calls a macro function, it does
    * something like this.
    call function '/SAPAPO/MACRO_FUNCTION_HERE'
            exporting
              plob_values      = i_s_adv_plob_values
              sdp_book         = g_c_advf_sdp_book
              sdp_view         = g_c_advf_sdp_view
            tables
              cols_index       = i_t_cols
              value_tab        = l_t_value_tab
            changing
              f_calc_error     = g_flg_calc_error
    As you can see, the g_flg_calc_error variable
    is passed in the "changing" part of the call. The macro  function being called can then use the f_calc_error
    variable to change the value of the global
    g_flg_calc_error variable. In fact, the macro function being called can also check (by looking at the f_calc_error variable) if the last macro function reported an error.  The CALC_ERROR macro function just checks the value of f_calc_error parameter (w/c in fact is the value of the g_flg_calc_error variable) and returns "true/X" if the f_calc_error was set to true by the last macro function.
    Hope this helps in clearing things out

  • [Fixed?] Cannot use mouse and touchpad at the same time after upgrade

    Dell Inspiron 6400 laptop, Synaptics touchpad, external wireless USB mouse (Logitech).
    Yesterday I did a full system upgrade which among other packages upgraded
    [2007-11-08 00:06] upgraded synaptics (0.14.6-2 -> 0.14.6.99-1)
    [2007-11-08 00:06] upgraded tzdata (2007h-1 -> 2007i-1)
    [2007-11-08 00:06] upgraded xf86-input-keyboard (1.1.1-1 -> 1.2.2-2)
    [2007-11-08 00:06] upgraded xf86-input-mouse (1.2.1-1 -> 1.2.3-1)
    [2007-11-08 00:06] upgraded xf86-video-i810 (1.7.4-2 -> 1.7.4-6)
    [2007-11-08 00:06] upgraded xf86-video-vesa (1.3.0-1 -> 1.3.0-5)
    [2007-11-08 00:06] upgraded xorg-server (1.2.0-5 -> 1.4-4)
    Before the upgrade, I was able to use both the touchpad and the mouse at the same time, using the following xorg.conf settings:
    Section "ServerLayout"
    InputDevice "Touchpad" "CorePointer"
    InputDevice "USB Mouse" "AlwaysCore"
    Section "InputDevice"
    Identifier "USB Mouse"
    Driver "mouse"
    Option "Device" "/dev/input/mice"
    Option "SendCoreEvents" "true"
    Option "Protocol" "IMPS/2"
    EndSection
    Section "InputDevice"
    Identifier "Touchpad"
    Driver "synaptics"
    Option "Device" "/dev/psaux"
    Option "Protocol" "auto-dev"
    EndSection
    After the upgrade, the touchpad was still working with these settings but the mouse wasn't.  I then changed the xorg.conf settings as follows:
    Section "ServerLayout"
    InputDevice "USB Mouse" "CorePointer"
    InputDevice "Touchpad" "AlwaysCore"
    with the InputDevice sections remaining the same for USB Mouse and Touchpad.  After this change the mouse was working but the touchpad wasn't.  Finally, I changed the xorg.conf settings as follows:
    Section "ServerLayout"
    InputDevice "Touchpad" "CorePointer"
    InputDevice "USBMouse" "SendCoreEvents"
    with the InputDevice sections remaining the same for USB Mouse and Touchpad.  This didn't change anything from the last setting: the mouse was working but the touchpad wasn't.
    How can I restore the ability to simultaneously use mouse and touchpad?
    Last edited by RobF (2007-11-09 20:20:54)

    Try this:
    Move "SendCoreEvents" to the Touchpad line (replacing the "AlwaysCore" bit) and then comment out the USB mouse.  So in the end, it'll look like this:
    Section "ServerLayout"
    InputDevice "Touchpad" "SendCoreEvents"
    # InputDevice "USBMouse"
    EndSection
    Restart X and see if everything is working right.
    PS: You may also want to consider changing the Touchpad device line to "/dev/input/mouse2" instead of "/dev/psaux" as I believe psaux has been deprecated in kernel 2.6.  I could be wrong, but I can tell you that /dev/input/mouse2 works great with the touchpad on my Dell e1505.

  • Is it possible to delete a plot with using mouse to select it on the graph control?

    For example, when I use PlotLine to plot thousands of lines on the graph control, I want to delete some of them, but there is thousands of plotHandle generated.
    How can I get the plotHandle of the specific line on the graph control with using mouse to select it?
    If I record information of the lines, ex. the plotHandle and the coordinates, on a table or list, etc. , I have to compare the information of lines to get the plotHandle of the specific line.
    Is there any user-friendly way to delete a plot by select it on the graph control?
    Solved!
    Go to Solution.

    Sure! Look at the example located in \samples\userint\graphcursors for an example of how to accomplish this task.
    Briefly:
    The cursor must be in "Snap to point" mode
    (To be confirmed) The graph must be in "Retain" data mode
    You must have a callback for the graph control
    You can use GetGraphCursorIndex to retrieve the plot handle
    GetGrpahCursor retrieves values of cursor position in engineering units

  • Using mouse overs with pop-ups

    I'd like to create a pdf using mouse overs to display otherwise hidden text (in describing various portions of a photo in the doc).  Can anyone lead me in the right direction as specific guidance in 'Help' has so far been limited?

    You can use the "Tooltip" for an easy method. You can also use teh "On Focus" and "On Blur" action of a field to show or hide a hidden field by either the drop down actions or JavaScript.

  • Scroll list down by page wise using mouse

    hi experts,
      how   can we scroll a list page wise  rather than line wise using scroll button of  mouse .
      my requirement is to generate a list consisting of 38 lines per page and each set of 38 lines
      should come in a new page that i have done using new-page, but problem is when i scroll
      down a list using mouse scroll button next page should be displayed rather than scrolling
      line by line . just like using pagedown key of the keyboard,
    thanks in advance.

    I think this is not possible, I don't think controlling the mouse operation is possible

  • What is the advantage of using methods to return objects?

    Hello there,
    What is the advantage of using static methods to return
    objects? Isnt this a Factory Pattern ?
    What is the real advantage of using methods to return objects
    rather than using public constructors to create objects ?
    Can some one please explain
    Regards

    I think there were two questions. The first (why
    static) is well answered but I hope somebody can
    answer the general question - why whatever =
    createSomething(); as opposed to whatever
    = new Something(); - because inquiring minds
    want to know.I thought I answered that question. Perhaps I need to be more specific.
    For the Singleton pattern, you don't want a new instance (except possibly the first time, if you're using lazy instantiation).
    For the Factory pattern, you might not always want an instance of the actual class containing the static methods, so new won't work.
    If, on the other hand, neither of the above holds, there is no reason not to use new (unless, of course, anyone can come up with another use of static creators).

    You can implement the listeners on any class, even one that (implicitly) extends Object. What matters is that the listener is added to the component that needs to use it.
    That said, why do you want to extend JFrame? Are you adding functionality to the JFrame to justify extending the JFC class? Note that extending JFrame allows the users of your class to access the functionality of a JFrame, is that really indicated here?
    one class that extends JFrame, and one can draw a line on JLabel, embedded within JFrame!So you still have to override paintComponent of the JLabel, which implies using an anonymous inner class.
    Starting with the example already posted, that would be:
    import java.awt.Color;
    import java.awt.Dimension;
    import java.awt.Graphics;
    import java.awt.event.MouseEvent;
    import java.awt.event.MouseListener;
    import java.awt.event.MouseMotionListener;
    import javax.swing.JFrame;
    import javax.swing.JLabel;
    import javax.swing.SwingUtilities;
    public class DrawLineTest
        implements MouseListener, MouseMotionListener {
      JLabel label;
      int x0, y0, x1, y1;
      private void makeUI() {
        JFrame frame = new JFrame("DrawLineTest");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        label = new JLabel("FFFF") {
          public void paintComponent(Graphics g) {
            super.paintComponent(g);
            g.setColor(Color.BLACK);
            g.drawLine(x0, y0, x1, y1);
        label.setPreferredSize(new Dimension(500, 500));
        label.addMouseListener(this);
        label.addMouseMotionListener(this);
        frame.add(label);
        frame.pack();
        frame.setVisible(true);
      public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
          public void run() {
            new DrawLineTest().makeUI();
      public void mousePressed(MouseEvent e) {
        x0 = e.getX();
        y0 = e.getY();      
      public void mouseReleased(MouseEvent e) {
        x1 = e.getX();
        y1 = e.getY();
      public void mouseDragged(MouseEvent e) {
        x1 = e.getX();
        y1 = e.getY();

      public void mouseMoved(MouseEvent e) { }
      public void mouseClicked(MouseEvent e){ }
