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

  I'm trying to reproduce the pattern-block which is attached to this issue, but I don't know how I connect the waveform to my clusters of berries. I get an error that "the type of the source is table 1 d of cluster of 2 elements. The sink type is 1 d doubles [64-bit real (precision ~ 15 digits)].

  You need a chart xy, not a waveform graph.

  (Remember also that this table index is resizable. You only have a single instance. Your photo code is old, ~ LabVIEW 4.0 or MORE)

• 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.

• 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.

• metal theme waveform graph

  Hello

  I use the metal theme to design a façade of Labview.  I would like to plot x, y of the data on a chart, however, there is only a graphic of waveform and waveform Graph available in the metallic theme.  Can you help me in tracing the x, the data is in the curve of waveform in the attached VI?

  Thank you

  hiNi.

  You can customize the graph of the metallic wave and replace it with a XY Chart and set some properties to match the waveform graph

  Or let me do it for you

• 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.

• rotation of waveform graphs

  Is there anyway to rotate a waveform graph, so that I can view them vertically? (the wave moves vertically, rather than left to right)

  You vote for this idea on the exchange of ideas, swap axis allow for graphics signals and diagrams intensity (and possibly others)

• How convert the waveform on the table of waveform waving on waveform graph

  Please answer now...

  Your other post indicates it is a thesis, I consider homework. What did you do? What do you mean? What do you get a waveform graph? You have one, or the plots of 10? If you have a parcel, what you get as the data type for the data in the chart? If you have more than one conspiracy, what do you get? What is the data type that accepts a waveform graph? Have you looked to see how that is defined?

  For example, let's say you have a parcel on your chart. When you get the data, you get... a table 1 d of values. It's kind of logic, right? Well, what is the type of waveform data? It consists of a starting point, time delta between points and an array of values. Hmmmm... So, what about using the wave function of build? Just a thought...

• How to get the individual history of the multiple waveform graph plot

  I have a table of waveform with several plots, which is a cluster as input.

  I want to calculate the average of each of these plots. With simple concession of waveform graph, all I had to do is to use the property in the history of the graph node and pass the history to the generation averaged vi. With the array of multiple locations, I am unable to get the history of each parcel.

  The property of the history of the land multi card node is an array of custers, not quite what I need to calculate the average.

  How to me history of individual plots?

  Thank you.

• 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!)

• Two background colors for the same waveform graph

  Hello guys!

  I have a question for you: I am a new user of labview, so please be nice!

  So here's the deal: I just created a thanks 4 thermocouple temperature registration program.

  In real time, I then have a waveform graph 4 curves as soon as I start my program. And in my program, I had a button that allows me to record the temperature in a file for a period of time at a certain frequency.

  So, what I have is: I got my chart of waveform with a black background for example, and once I pressed the button, the background color will be changed automatically to highlight the part of the graph where the record occurs, then the background will return to the black after finished recording. In this way, on the same graph, I could say that registration took place from here to there by looking at the graph. I have two different background on the same graph.

  I don't know how to change the background of a chart using the property node, but is it possible to do what I want?

  I hope I'm clear. Otherwise, feel free to ask me for more details... I might post my vi if necessary

  See you soon

  Well, I know this is not exactly what you want to do, but you can try the following.

  Change the color of the line on the chart when recording occurs.

  You could therefore have a red line, then press on save, then it turns blue, then back to red.

  And when that is confusing since you have 4 different lines on the chart 1,

  You can change to a red line and a dotted red line, for example.

  Would that be acceptable? If so, I can show you how to do this.

• Change the axis label w.r.t. the scale automatically in the waveform graph

  Hello

  Is it possible to change category axis labels and the value the axis according to the scale automatically? I have a waveform graph which is automatically resized and values on the y-axis of milli, micro and nano volts according to the results of the output from the tests carried out. I need the label of the axis to change automatically according to the scale... Could someone tell me please how to do this. Thanks in advance.

  Best regards

  Julien

  Alain,

  I don't know exactly what you want.

  If you want to just scale to change as follows: 10n or 5u, use the property format scale IF the Notation.

  

  If you want to change the name of scale label text, you use the YScale.NameLbl.Text property. The attached VI shows one way to do something like that.

• switch between log and linear waveform graph

  I have a waveform graph that plots linearly. However, it causes an error during the logarithmic line tracing. Is anyway to create a switch that allows me to change between log and linear plot without creating additional graph?

  Thank you

  Chris

  Use a property node: Y Scale.Mapping Mode.  Written 1 to the node passes in logarithmic mode and 0 is for the linear.

• How to use offset and multiplier in waveform graph?

  Hello

  I m using a waveform graph and I wanted to update its the x axis scale depending on the value of the multiplier. Also how this

  shift multiplier formula n works (deltaX) * X + X 0? What is delta X and X?

  Kind regards

  vijtin

  Hello

  X 0 is the offset, and X is the multiplier.  If the graph will start at an offset issue and will be aa at the time value delta multiplier.

  for example

  If you have these X-values normal: 0; 1; 2; 3; 4; 5 and a multiplier of 2 and 5 ofset you would get the result on the X - as = 5; 7; 9; 11; 13

  Hope this helps

• 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.

  Here's my VI.
