• move the data points on the waveform display

  Hello

  No idea why the waveform display to my VI has shift the data points? The third tab of the screen does not display this problem. I took a video of what happens to better illustrate what I'm talking about and attached my VI to identify the problem.

  I am currently a sample of data from a DAQmx and storing in a queue until data backup button. Everything works well, but the problem is the display of actual data, which, although sense points, it shows move in a small area around where they are drawn in the first place. It happens even when I erase the visible data and restart the collection of data, as shown in the video.

  Thanks for any help you may be able to provide.

  The amount of data you draw? If you draw a lot more datapoints that there are pixels on the x-axis of the graph, you can get peaks that appear to move because of graphic interpolation LabVIEW has to do.

• How display the waveform acquired DAQ card separately in wavefrom graphic

  I NI 9239 DAQ card and it has four channels. I need to create a user interface graphic labview in which I need to display all the forms of four wave separately. If I select all four channels of the daq assistant and connect the waveform table all four waves are coming to overlap... I need separately for the treatment... what should I do?

• 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.

• Display the waveform of the multimeter (34401)

  Hello

  I have a few problems in the view the using waveform graph. It seems that I can not connect the data directly to the waveform curve.

  The error indicates that the problem is impossible to connect two different types of terminals, the source is string & the sink is table 1 d. Please advise on how I can view statements in a graphic form.

  Thank you very much for taking you time solve this little problem. Thank you and get better.

• Can I change Clips Audio waveform display in the timeline panel to resemble CS6 in CC?

  I just changed my CC of CS6, and I don't like how waveforms of audio clips in the timeline panel look in creative cloud. in CS6 is show the waveform centered in the clip, but CC, he seems to have cut in half.

  I have change a scripted show and have the Visual cues when a line starts and stops was incredibly useful. It was very clear in CS6 because I could see peaks and valleys very easily.

  Can I change how the waveforms of audio clips in the panel mounting back to the way it was at CS6? I want it to be centered in the clip and not cut in two.

  Thank you

• Updated reading (waverunner 6100) scope of the waveforms?

  I use an oscilloscope (LeCroy) waverunner 6100 and able to get the waveforms of the via drivers downloaded from NI.com. But I would get a waveform only when a new acquisition happens (not not to read the same waveform all the time). How can I do? There is a "read only waveform.vi" available on the site, but it does not work with AUTO trigger mode (I think). I am currently reading in waveforms while loop with "Fetch waveform.vi", but I'm not sure that it reads as "refreshed" display... Here I read some registers (whatever) status or there is already an existing solution?

  Hello Alex Harley,

  Alan LeCroy Tech Support here.  The waveform read various screw run the command 'Arms', so it is not for use in Normal or automatic trigger mode. We recommend that you use this command, because it uses the unique relaxation mode, which is the mode to use when you want your program to control when the scope triggers and so make sure that you're reading data retrospectives that corresponds to a specific triggering event.

  If you prefer to run in automatic mode or Normal mode, you must use the VI 'Wait to acquire full' which is located in
  the range of data/Low Level function.  The looks for the registry "INR" testify to a new acquisition.

  Best regards

• 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.

• Control of data using multiple thermocouples via indicators and the waveform in real-time

  I apologize in advance for this question is probably a bit simple but I'm all new to labview and the forum and could use some advice. I have a CompaqDAQ with two 9213 16 modules of track and I'm trying to read in 30 thermocouples in a waveform, but also display 30 indicators so I can mark each indicator with the thermocouple for real-time tracking. Each thermocouple corresponds to a specific location and it is essential that the interface has an accurate indication or a label for each of them. I wonder if there is an easy way to do this in addition to split the signal and have 30 thermometers on my diagram? Perhaps a table any? If I use a table to create 30 thermometers, the DAQ assistant automatically sorts the thermocouples according to ascending numerical order. For example, would be the indicators of first and second on my interface automatically assigned to channels a0 and a1 of the first module, or should I do it manually? Even for the waveform?  Thank you very much!

  PS - Do not know if this message had need of more details, but let me know if more information is needed, and I'll give you!

  I see that you use the DAQ Assistant to create your task.  Now I understand why you may have about labelling.  It is easy of the seller NOR spiel booting...  But in any case, you already have a task to the MAX instead of use the DAQ Assistant?  The interface is similar and there may be a step or two, but your end application will be more effective and you will have more options with your data and properties.  For example, I tried to update the names of physical channel in the DAQ Assistant installation program, that it let you do, but it propagates that change forward to waveform chart legend.  Also, I don't know any property for this dynamic data type node, although I never use it either.  I suggest the setting up of your task and channels, Max if you'd give it a go.

  Since I thought I didn't really takes you all the way with you help, I wrote another one.  It uses a cluster, even if it's a bit barbaric.  I thought that there was a more eloquent way to do by changing labels, but I could not it works as I had expected.

• How do I either set channel name of a graph of cluster or get a 1 d waveform chart to start different time (t0) for each line of the waveform?

  I have a chart single 2D out a conditional of a loop indexing output such that over the rows of the table are not the same size. -Basically, they have different starting and ending points and sizes. -Not so concerned by the endpoints, because as soon as I get correctly starting points, everything shows fall in place.

  The challenge is that when I try to have the variable t0 (start time) for each line, the wave of construction vi form would always keep each line at the same starting point.

  I used the approach bundled with success (the cluster approach ensures that each waveform starts at different times according to the guidelines of my t0 defined for each line) but then I'm not able to get in the channel names I could make using the graphical approach (wave generation) waveform.

  In essence what I get here, I'm losing here.

  Because I don't want one of my mentors, Bob and Altenbach have fed up with me I have attached a vi this time

  Attached VI shows a combination of the two attempts (first with the waveform graph) and then with the graph of cluster

  1. with the first (graphical waveform), I get my channel names as you wish, but the alignment of the wave is not correct.

  2. with the second (graphical cluster), the alignment is good, but I can't do the names of channel in the chart, even if they are present in the cluster.

  I read some reviews that mentions that attributes can be displayed with waveform and data Dynamics (not clsuters) so I guess that's why.

  I saw another report indicating the start time for a waveform 1 d will always remain the same for the rest lines defined for the first line even if changed for the following lines in a loop.

  So I guess my question is: what is the way around questions like that?

  First of all, let me be the first to the congratulate and thank you for finally posting a code!  I'm not 100% certain I understand your question or your code, but I have an idea, perhaps, of what you want to do, so I wrote a little VI who made something simple that could be relevant.

  You mention waveforms of different lengths and beginning at different times.  You also want everyone to have a unique attribute (although I'm not sure what you want to do with the attribute).  So, I did the following:

  1. Generated an array of 100-sample random to represent one second of a waveform.
  2. Created 4 waveforms on this 100-sample basis.  The first waveform (channel 0) is just these 100 points.  The second, 1 channel, is the concatenation of string 0 with the base of 100 samples, or a waveform "double".  Channel 2 is 1 string concatenated with the base, and channel 3 is 2 string concatenated with the base.
  3. In order to trace the four channels that they rest 'on' the other, the waveform has the number of the channel added to it.  Channel 3 is 3 + (4 copies of the basis of 100 points), a waveform 400-point random centered around a shift of 3.
  4. All channels have dt value 0.01 (but I guess I could have varied, as well).
  5. To make the channels start at different times, I started channel N N seconds before channel 0 (by subtracting the index of the loop, I, T0).
  6. For each channel, I created an attribute called "Chan" equal to "Channel N" (where N = 0, 1, 2 or 3, as the case may be).

  This is the plot that results. Scale X is the absolute time value (no Date) using the 24-hour HH: mmS format.  You can see that the plots are 1, 2, 3 and 4 seconds of time, and are offset from each other by a second.  I used the trace attributes to change the name to the respective attribute.

  

  The code to do this is very simple - I almost don't need to show it, because I think it is completely described by the text above, but this is here:

  

  Now, it was not that much faster that some of your previous posts, when you refused to your postcode, "guess us" what you wanted (but not to not correctly guess), you tried to "push" us in the right direction (still refuses to post code), and no one seemed very happy?

• PP 2015 cannot find the waveform monitor

  Have you tried to open the waveform for the portable and desktop monitor and options seem to be composite diabe, alpha and multi-cam, if you click Display Mode. However, the PP said help click on the source program or chronology and window to select. But only litters I see are Lumetri.

  Uses computer laptop Lenovo Z570 and HP Z800 with Adobe certified card Nvidia GTX and the same issue on both.

  Thank you all!

  The old waveforms have been removed in 2015 CC (9.0) and replaced by the new and improved Lumetri Scopes. Go to the window menu > Lumetri Scopes.

• Why do the waveforms appear sometimes and sometimes not, in making sequences?

  I use two camcorders from Sony to make 2-camera shoots of operas. I use the same cameras, first CC 7.2 and the same workflow as follows:

  1. Ingesting the two cameras AVCHD video.
  2. Create a sequence of each clamp so that the waveform can be displayed on the timeline and develop a common sound to mark for synchronization. This could be the first note of music or (better) something someone falls during the silence between applause of the conductor and the beginning of the work. Mark by (new workflow 7.2) by selecting the item and pressing M.
  3. After checking the mark on each clip is based on the same sound, remove the two sequences; they reached their goal.
  4. Select the clips in the project Panel, in the order (click on camera 1, hold down Shift or Control in function, then the camera 2).
  5. Right-click and select Create Sequence of Source multicamera; because the clip markers have been applied, the choice of brand item is preselected and is right for this sequence.
  6. Right click on the sequence obtained from Source MC and choose to display it on the Timeline. Expand the two stereo audio tracks (the best for the Tilde key to bring up the timeline without other elements) and make sure they are synchronized at the chassis level. The elements in the timeline appear in blue and displayed the waveforms.
  7. Right-click on the Source sequence in the project Panel, and then choose "new sequence of the clip. It comes to the target sequence. It shows a track and an audio video (will of course switch between multiple cameras well directed and controlled).

  Here comes the question: sometimes I have the audio waveform. sometimes not. Same workflow; same cameras; same computer. Different result! (I would put in pictures, but the device "insert an image" in the forum seems to be broken - just watch a gray square with "Insert an image" rather than a selector of any to fetch the image!) The audio itself is not affected. I had many prefer to see the audio not; It is a plan through my project - for example, dialogue and musical numbers appear quite different if I know where I am audio I don't have the litter box to the top of my calendar with useless markers.

  Thanks to anyone who can answer...

• How to sync Audio using the waveform

  Win 7 Ultimate

  Gentlemen

  I imported a first project in after effect cs4 added all the effects and pretty much everything is done

  but I did not like my AUDIO channel, so I went and he changed by another that I like, but they are the same song, but different EQ, now my question is:

  How can I sync my old images with my new AUDIO track, as I said, these are the same some EQ but different.

  the problem is that I can't see the wave so I can match.

  Any help will be appreciated.

  After Effects can read the audio file, as it should be able to display the waveform:
