Cursor name position in Waveform Graph

I lost the cursor name in the waveform graph, after programmed the cursor positions.
I enabled 3 cursors, shown the cursor names, and programmed their positions in my VI. After running the VI, all cursor names are gone. I believe they are moved to somewhere out of the plot range due to LV malfunction. I cut and copy the graph to the VI attached, and enabled a new cursor, which looks good.
I need to get the lost cursor names back (manually is OK). I also want to know how to avoid this.
I am using LV 7.1 under Win XP Pro.

Study_Missing Cursor Name.vi ‏71 KB

I have created a test vi that could generate this problem. I generated a waveform graph and label each peak with cursor name. Then I copied the waveform graph and paste to form another waveform graph 2 in which the cursor name is gone even the show cursor name is still enable. I have not been able to find the cursor names from the waveform graph 2.
I am using labview 7.0

    HI Mike
    Thanks for the reply. When I apply the logic to reposition the cursor in the scale range event only one cursor is moving to the zoomed in position. The other cursor remains out of  graph scale. I tried to repeat the same logc but it didn't work.  Could you please tell me how to get the 2nd cursor also in to the scale range. Sorry i'm fairly new to labview. I have attached the pic of what I tried.  Thankyou in advance

  • How can I get the cursor value from a waveform graph

     Is there a way to get the value of cursor position on the waveform graph so mathematical calculations be performed on those values. We can see the value in cursor legend, but can we extract those values for future calculations in the block diagram somehow.

    Right-click on the waveform graph icon.  Select Create>Property Node>Cursor>Cursor Position.  That spits out a a xy cluster for the current cursor position.
    If you have more than one cursor, you can either set up a loop and set the Active Cursor property node (right click the property node and select "Change to Write") or you can pull everything you ever wanted to know about every cursor with the Cursor List property node. 

  • Refresh cursor value in a waveform graph

    Hello, I am tryig to do a vi that can read PNRF files from perception and then it will analyze the data of the waveform, but I am having some problems with the reading of the data
    After getting the waveform graph, I created an event of that waveform graph that would activate each time there is a cursor release, but it cannot work once the sequence reaches that point of the event.  I am working step by step on this vi, and after being able of having refreshed data I will do the same with a second cursor. Also, I cannot find the way to separate the waveformgraph channels into different displayed waveforms, is it because it is a waveform graph and not a waveform chart?
    I am attaching the used vi

    I have simplified your vi just slightly. You dont need two while loops, two event structures, event structure timeout, sequence structure (read up on data flow using error terminals). I dont have access to the file you are reading so I have disabled that section with a simulated waveform.
    As you can see the cleanup  has messed up your comments etc. sorry about that.

  • Cursor's position in xy graphs

    How do I get the X position of two X axis cursors on a XY graph so that I can do numerical calculations?
    I am including a VI that will produce a graph initially. After I have the graph I want to use the cursor position to determine the time between the cursors.

    The problem with your property node is that you don't have the Active Cursor property. Before you read the x position, write to Active Cursor to select the cursor and then read the x position. In your case with two cursors, the sequence would be to select Active Cursor 0, read x, select Active Cursor 1, read x. You also should put some data flow between the while loop and the property node. Putting the property node on the right side of the diagram doesn't mean that it will execute after the while loop finishes. In fact, it won't.

  • With two cursors on just one waveform graph, how can I acquire the X values of each cursor to use them in other functions?

    I can get the x values of each function to display on the front panel with no problems, but I have not been able to acquire this information from the front panel.

    You use a property node to programtically retrieve the cursor values. For each cursor, first use the property Active Cursor to select (0 for the first and 1 for the second) and then the property Cursor Position:Cursor X. See the attachment.

  • Move the name of cursor (not the cursor itself) on the XY graph

    I use cursor list property to overlay cursors on the XY graph, everything looks fine except that the name of the cursor and the cursor are at the same position, so it's hard to read the name of the cursor. Is there anyway to dynamically move the name of the cursor?

    No, you cannot do this programatically, the cursor name position may only be moved manually when the Name is "Trackable" (when Allow Drag == TRUE). However, you can use cursors in pairs of two to accomplish this. Use the first one as a normal cursor and the second one only for the cursor name, making the line (Hair Style) and point (Point Style) invisible (=0). If you have multiple cursors, just treat them as pairs and multiple your index by two, when finding the index of the pair.
    Good luck,
    Jim

    Hi,
    Is it possible to programmaticaly remove an added cursor without having to
    acces the cursor menu on the waveform graph?
    Best regards,

  • Keeping Digital Waveform Graph Channel Name constant

    Hello All,
    I have currently run into a problem where LabView decides to change all of the channel names in my waveform graph to some type of default setting, e.g. Line 1, Line 2 etc.  I was wondering is there a possible way to keep the channel names on the digital wave form constant even if I change some of the digital waveform parameters, or pass a null digital waveform constant through one of the channels?  Any help on this would be much appreciated.
    Example:
    Problem
    Digital Channel Name Before:                                 Change Parameter:                              Digital Channel Name After:
    Valve 1                                                                     Only Channel 1&2 used                            Line 1
    Valve 2                                                                                                                                       Line 2

  • Transition measurement vi cursors displayed in waveform graph are moving outside of scale

    Using a waveform graph to display pressure over time. I wanted to be able to calculate the fall time of the pressure over time so I'm using the Transition Measurement vi. I copied exactly what was in the example for transition measurement inside help and it is correctly determining the falling transition time but I am having a problem with the cursors on the waveform graph. I should be seeing a set of green vertical cursors marking out the fall start time and fall end time like in the picture I've attached (capture2) like in the example. The problem is they both always start at 3.43 (capture1) and after each sample period they increment by one (4.34, 5.34, 6.34) The come right out of the bundle from the transition measurement output as those numbers. The period of the signal I'm interested in is always less than 2 seconds, so I never see the vertical cursors.
    I've tried substituting my daq signal with a sine wave generator and it does the same thing.
    The block diagram is in the first capture
    also I would be interested in finding out exactly how the numbers wired to the active cursor property of the property node for a waveform graph relate back to the actual cursors on the graph. Are they just automatically numbered starting with 0 from the top-down?

    Hi Wayland,
    The reason the cursors are always apparent in the example VI for the Transition Measurement.vi, is because the signal being generated is always resetting. So, the signal resets to a 'new' signal for the cursors to go over and therefore always remain in the somewhat same location. The Waveform Graph is also configured in such a way that it will not move or continue to show new data coming in, the data cursors have moved onto. So in your case, you will want to right click the graph and make sure "Ignore Time Stamp" is not checked/selected. This will make it so the graph keeps up with your incoming data and the cursors. You can check this in the example file by removing the True Constant going to the waveform generator and changing the time stamp option previously mentioned.
    In order to view the available cursors and their numbered position, you can right click on the Waveform Graph and select properties. In the properties window there is a Cursors tab, inside this tab at the top is a drop down menu that lists all of available cursors, indexed starting with 0 at the top.

  • Center the cursor on the Waveform Graph?

    I have a waveform graph where the user can adjust the scale on both the X and Y axes.  The "problem" that I am having is that if the scale's range is set too far from where the cursor is at, the cursor will be off screen and not selectable.  So, I am trying to center the cursor to the scale when the scale is changed or via a button.  Here is the code that I have written for one of the Cursor plots:
    Select Case setBlueCursor
    Case 1
    blueCursorPt.Plot = plotInlineTorque
    inlineTorqueMax = yAxisInlineTorque.Range.Maximum
    inlineTorqueMin = yAxisInlineTorque.Range.Minimum
    blueCursorStartY = (inlineTorqueMax + inlineTorqueMin) / 2
    blueCursorStartX = (XAxis.Range.Maximum + XAxis.Range.Minimum) / 2
    blueCursorPt.YPosition = blueCursorStartY
    blueCursorPt.XPosition = blueCursorStartX
     This code will center the cursor like I want but then I can't move the cursor after that as it is "stuck" at the position that I have coded it.  The problem appears to be with the last two lines of code here.   I do not know of any other way to do this though.  I have tried the "moveCursor" method but the end result ends the same way, with the cursor stuck in the center and can't move.  Any help on a solution?  Is there a better, easier way to do this?  I'm new to Measurement Studio and .NET. 
    Thank you

    This code works.  It appears that I was calling the subroutine that this code is located in over and over in another part of my program. 

  • Dispaying a waveform graph with control of the cursor in the document.

    I would like to be able to control the cursor when I save my waveform graph in html. I'm currently saving the graph through the report vi's

    I am not sure I understand your question. Do you want to simply control where the cursor is on the picture you are appending to the html report. If so then when you use the Append Control Image to Report VI it basically takes a snap shot at that moment and displays it. Therefore you just need to place the cursor where you wnat it before you add the image.
    To programttically control the cursor you will need to use property nodes of the Waveform Graph. A good start would be the property cursor>>cursor position>>all elements.

  • Cursor Name on Graph Not Visible (though set to be visible)

  • How to modify the cursor palette size in a waveform graph programmaticaly in LabVIEW8

    In previous version of LabVIEW it vas possible to create reference to cursor panel (array) so it was possible to resize, change number of rows, in it. It will be useful for me to have reference to TreeControl contained in cursor legend. How to create this reference? The method described in the manual works for scale legend but not work for cursors panel.

    Thank you JLS once again.
    In my opinion the cursor palette at list should have the following functionality:
    Automatic resizing of the panel while adding and removing cursors programmatically (like plot legend)
    Positioning the panel programmatically (like plot legend)
    Hiding any columns and rows. For example when I hide one of the cursors (let say the second one, not necessary the last one) also this one should disappear from cursors panel, removing cursor from cursor list might be inconvenient. If I have one cursor and not enough room to show cursor panel I can not hide the cursor name column that is unusable but occupies place on the panel
    Altering number of column and rows programmatically. If my cursors serve for selecting part of the signal to be processed (for example trimming signal) it is sense less to show cursors Y position
    Hiding cursor navigator, it works very badly (try to move cursor only to the next measurement point to select exactly for example 10000 points), so I move it under other controls.
    Formatting data displayed
    Having additional elements (coming from underlying tree control) is not necessary in several cases. Life will be much more pleasant if it will be possible to get reference to this tree control.
    By the way it is possible to customize this palette. In design mode configure WaveformGraf to show cursor legend. Select it and then select from menu “Customize control…” Now you can do whatever you (I) want, for example change the column name from X to Time. Save your work, if prompted replace original with just designed and… nothing changes – funny isn’t it?
