problem of waveform graph

I'm working on a graph of waveform for a project, I want to use a node to control the time of the chart base. It works, but switching during the chart will display more divisions that I designed for a very short period of time, which is annoying. I have attached the vi and I'm appreciated if someone could help me on this problem.

Just found the solution, it seems that I sequence the function of the node of the property or the graph will be confused. Your suggestions has informed this solution. Thank you!

  • missing samples in the waveform graph

    Hello world

    When processing a file .wav into pieces, I noticed that there are missing samples on the waveform graph where two pieces must be met for the display. What could be the cause of this? Any help appreciated. Thank you!

    Milan

    Your method of reading in pieces in a for loop is create a table 1 d of waveforms with the tunnels of automatic indexation.  It is as well as what you have the data appear in different plots.  I don't know if that's what you want.

    But if this is the case, the problem is that you get to the last point of the first plot, and the first point of the next parcel is a different value.  Because they are two different plots that you do not get the line to join them, as you do between points that are part of the same plot.

  • waveform graph

    Hello

    I have a question about the waveform graph. My prolbem is that the x-axis of graphic waveform shows only up to x = 0.1 and it does not show the chart more than that, and when I increase the X-AXIS scale in his PROPERTIS (lets say at x = 2), increase the Max on the x-axis (x = 2) but the chart presented to the 0.1! I have attached a very simple code that shows my problem.

    Could you help me please? I need the graphics to show me for all values x, x = 0 to x = 10.5.

    Thank you

    Soran

    Hi Soran,

    Sorry, your question is still not clear to me.

    You hear all the values up to 10? I kept freq = 0.1 and adjusted other values, don't know if that's what you are pregnant.

  • Overload CPU display with waveform graph

    My sample code (yahoo.vi) presents the 2D DBL in size of 30, 000 * 2 table.

    Whenever the 2D table was displayed with waveform graph, I found there were big delay (around seconds) by CPU overhead but the time was very short.

    Once this has happened, the computer (8108 PXI double heart, 4G of memory, 32-bit win7) has been slow to exploit something.

    Is it bug or problem comes from the computer? or do you have a solution?

    labmaster

    My version of LV is 2009.1 (service pack installed)

    You need to transpose the table! (or right click on the chart... convert table)

    You are graphing 30000 plots with two points each (hard!) instead of 2 plots with 30000 points each (easy!).

    (Imagine you would display the legend of the plot with 30000 plots, it would be a mile high!)

  • Multiple waveform graph, history of waveform card

    Hello to all my colleagues.

    I have problem with software of my purchase. I create software for the acquisition of 40 signals. I need to view and save these signals. I measure these signals with different frequencies (this depends on the user's selection), but the lowest frequency is 500 Hz and the highest is 2 000 Hz. Because I see a different size of X scale (5 sec - 60 dry), I decimate these signals for display and display only 100 samples per second.

    I think that my problem is related to a very long history of waveform graph. When I display all signals in a single diagram, permanently signals are not displayed and the table is larger than the correct size of X-scale, means that the courses of the waveform graph freeze. I think the problem is connected only with display and no acquisition because I tried to check the measured data and there isn't any problem.

    You have one any opinion how can I solve my problem?

    Please, help me, because I'm out of ideas.

    Thak you.

  • How to display more than two waveforms on a waveform graph?

    Well, I have a question in the basics of waveform graphs. I have to post four waveforms simultaneously in my program. I can see two graphs on it, but when I try to display four waveforms, I get an error:

    You have two or more data types of cluster wired together, but clusters have different types or numbers of items.
    Cluster (unnamed), a group of 3 elements.
    conflicts with graphic waveform cluster, a cluster of 2 elements.

    Is there anyway that I can change a graphic in waveform to a cluster of 4 elements? Because I borrowed this waveform of a VI example on waveform cards "Charts.vi", so I guess it must have been programmed to be a cluster of 2 elements.

    I hope that I have my question clearly.

    Thanks in advance

    One of the problems that you have is that data from the DAQ assistant has a time stamp from now which is about 3 billion seconds

    Data from the simulated signals has a time stamp based on the beginning of the acquisition which is about 0 seconds.

    So, the table needs to be stretched early in LabVIEW time now to show all the data.

    Change signals simulated so that the timestamp is the result of an absolute time, then you should be able to see all the signals.

  • Newbie - waveform graph axis graduation issue

    Hi all

    I'm new to studio of measure (v8.0 with .net c# 2005) sorry if this question has been answered 10 times more, please feel free to point me to a previous thread.

    I have a request to:

    drive voltage analog sampling at 10 Hz reading 1 sample per tick.

    standard waveform graph axis X and Y and a plot as a collection of doubles.

    So far, it's something pretty simple and I can get all this work in the code example.

    My problem is that I want for my X axis to read between 0 and 1800 with the major divisions of 100 and minor divisions = 50. I would like for my actual graph however contain 10-point increments, so that would mean that there will be 500 points between each minor division.

    I looked down through the properties of the axis and I can't enough find the properties that I need to set.

    Can someone help me please.

    Thanks in advance.

    Hi Jamie.

    Thanks for the reply. I spent all the update yesterday my system of measurement studio 2012 + Dev Studio 2010.

    I put these settings, looking more closely at my data, I have a problem with my data acquisition analog voltage so I'll search through my solution and start a new thread, as I'm getting 3 times more data that I need, so it is causing my chart to be wrong.

    Thanks again.

  • Create multiple vertical lines for waveform graph

    Hi all

    I use NI 9234 USB vibration of rotating machinery data acquisition. A simple VI was made for this.

    The next step is the analysis, signals were well displayed waveform, time, FFT, all important values... and so on.

    But I have a problem with multi vertical lines of the waveform graphs, it looks very simple, and I tried many ways but have yet to get it with a good solution.

    Vertical lines are used to display the frequency of breakdowns of machines (such as we post 1 X, 2 X, 3 X,... more harmonics).

    Does anyone have a solution for this problem?

    Thank you very much!!!

  • Waveform graph lose history

    Hello to you all, useful forum fans!  :-)

    I implements an array of tape showing the values of several parameters in real time, using a waveform graph, but during the race he keeps resetting of the history of the card at irregular intervals.  Unfortunately, because it is for my work, I can't post the code.  I'll do my best to describe the problem and the installation program, however.

    I have a data acquisition loop to read the values in real-time in a table of the floats and stores it in a global variable functional memory data buffer that contains a table 2D of floats, a 'page' of floats by time interval.  This forum works at 50 Hz through the expectation of millisecond Schedule VI.

    I then a chart update the loop running at 10 Hz via forward schedule VI.  This loop reads the data of all samples buffer VI he has accumulated (usually 5, but sometimes 4 or 6) and converts it to an array of waveforms through the VI of waveform build by taking each column of data and by assigning to it, definition dt to 0.02 (50 Hz), and parameter t0 to time less dt current multiplied by the number of samples in the table.  The terminal waveform graph is then set to this table of waveforms.

    Most of the time that it works well, with the new values added the previous values to create a smooth graph of multiple plots with the correct values are displayed.  However, sporadically the chart Flash empty and begin to fill again from scratch.  I can tell is just jump in time (the axis of abscissa) because I can move the axis scroll bar and there is no other data to scroll.

    I in addition to these two loop loops a GUI-structure of the event and a task of State machine loop.  However, I have excluded these two loops ownership history of the graph through inspection and breakpoints.  This is why I can only think that there are conditions or the type of data which, once introduced in terminal results of the graph by adding DO NOT present data as usual.  Empty array is not the answer; I tested with a separate simple test VI, and therefore in the chart, keeping the currently displayed data but do not update new data.

    I would appreciate any idea what any of you have as to the possible causes of this behavior.  I apologize again for not being able to view the actual code, although I can work to establish a similar setup with the data buffer, etc. in a separate VI and after that.  Also, I would like to know if you want me to describe the other logic, settings, or the circumstances for you.

    Thank you very much for your help!

    Whenever I've seen this problem when you use a waveform he chart endded up being a problem with;

    (1) the number of parcels has changed.

    (2) the names of the plot has changed (WF attribute).

    (3) time info Goffy where t0 and dt were inconsistent with what was already posted (new data point a t0 that is earlier than what is already plotted this plot)

    It's a pain to figure out the first time.

  • How can I display only a part of the scale in the waveform graph

    This is the first time I try to use the waveform graph, since now, I used the table of waveform.
    The reason why I moved to the chart, it's that I need cursors.

    I have 2 problem

    the first: in the diagram, the graph moves when I add a new data and the scale of the x-axis stay the same size, in the right size I always saw the new data. How can I do that with waveform graph?

    Second: How do I say Labview to the day I click on the graph, I need that because when move graphic I lose the day, and to make I need to zoom out, I drag the imprecateurs.

    All this must be done programmatically. The LabVIEW graphic accepts tabular data, not only as the table and the graph doesn't have the ability to retain the previous points, like the story of a graph. You will need to retain previous values and then continually update the graph with the old and new values to get a shift register "chart as behavior. Cursors should be written programmatically re of each iteration, since you rewrite the entire graph.

  • How to connect a cluster of berries to a waveform graph

  • Save the Studio measure waveform graph as a file for reading later

    Hello

    I would like to know if there is an easier way to record data are rendered on a waveform graph (configured as a graphic of the band) to capture incoming data in the code and send copies of it to a file. It would be nice if there was a method to do this, with all relevant metadata stored in the file (color, etc.). Better yet, the file could then be opened in a labview application (for example, a TDMS file) for later review.

    Thank you.

    PS. I use VS2010 and MS 2010.

    So, it looks like you already have all the data points. For metadata that you mentioned, line color, plot colors, point colors, line styles, etc. are all accessible from the properties so if you wish, you can retrieve all that data.

    I think that upon return from t0 is the same compensation history, you can use the ClearData() method.

  • How to display the signal on a waveform graph in Labview Signal Express?

    Hello

    I want to display a signal in Signal Express 3.0 in a "waveform table", but don't know how to do it and I think that it may be impossible?

    In Labview, there are two ways to view data, a 'waveform table' or a 'waveform graph. The great thing with 'picture of waveform' is that it allows you to set a length of history and you can see the data move to the left (option graphic strip) that samples are recovered. It works perfectly.

    In Signal Express I can only select "Graph XY" or "Waveform curve" by doing a right-click of the mouse, but I can't select "table of waveform. Is it really true that it is not possible to view data in a graph of waveform "with Labview? (1 analog signal during streaming, 100 samples to read at the rate of 1 K)

    Thank you in advance,

    Enrique

    Hi Enrique.

    You are right that there is currently no graphic waveform in SignalExpress. The thing nearest you can join, is saved data under a log and then he looks one when recording (which I know this isn't quite the same interactive behavior).

    For your last comment, you wrote 'waveform curve', but I guess you meant 'picture' here as well.

    Sorry about that. We recently received this request, then perhaps in a future version.
