• How to view graphical waveform Excel data

  I have a file .csv with 4 data column.  I found something for another thread that allows me to display data from an Excel file in a table.  I have a problem with the following:

  (1) I need to display column data 4 but I can't seem to find a way to add other elements to the Invoke node so I'm stuck with power display only 2 columns of data.

  (2) why can't take my output and put it in a table, and then view it on a waveform graph?

  Please take a look at the attached VI.  I took notes in the block diagram.  When I try to join the Excel data to a chart, it indicates that the source type is a string, while the sink type is double.  How can this be when the Excel file has only whole?

  Help, please.

  Thank you.

  
  

• delay in reading the data when you are using multiple loops clocked on target RT

  Hello

  I have five loops clocked on a target of RT and I communicate to and from the host vi. All the loops of the value of the different priorities however when all running at the same time I found windows vi take up to 1 minute before reading the data. Four disabling loops to fix the problem. It is possible to start the app right after start windows vi?

• Track of multiple graphs on a single diagram of waveform with dynamic data types

  I'm putting multiple charts on a single diagram of waveform and data contract error. I was wondering if it has something to do with the fact that the dynamic data is used (I have had no problem with other types of data in the past). Does anyone know how to fix this? I have attached the following .VI. There will be a lot of. Live on the bottom which does not load, but they are not related to this problem.

  Thank you!

  I don't know what you're doing now, but a part of your origianl code is simply ridiculous. Your DAQ assistant takes a single point. You convert that into an array. If you had converted into a scalar value (which is) first place, your graphics update would have been fine.

  If you want to remove the DAQ Assistant, and then select generate DAQmx code. You'll be a little more closely, but it seems that it generates a NChan DAQmx Read 1Samp instead of a 1Chan 1Samp DAQmx read.

• Set the attributes for dynamic data waveform t0 zeros?

  HI -.

  A beginner to labview here, so please be nice ;-)

  I have a simple setup with mainly express screws where I follow the steps below in a while loop

  (1) collect signals with the DAQ Assistant, that generates dynamic data. It is the collection of samples of N

  (2) changing the attributes of the dynamic data using the express VI 'Set the Dynamic Data attributes'

  (3) storing dynamic data revised to a file by using the writing to the file of the measurement.

  The problem I was see is that whenever I have insert the express VI 'Set the Dynamic Data attributes' in the data flow, I find myself with a file where synchronization of the signal (i.e., the waveform t0) was cancelled. This seems to happen any dynamic data attributes, I edit. For example, even if I try to set the name of signal I find myself with out having a nulled-out t0

  FYI, I'm using Labview 2009 9.0f3, 32-bit

  I have attached a code simplified showing what looks like a bug to me. Any help would be appreciated!

  It looks like a bug to me as well. Also, unlike other screw Express, you do a right click on it and select open the face before seeing what the problem is. It's pretty simple to find a work around. I converted to a waveform, has obtained the t0 and handed that back as the timestamp for the signal of slected.

• Updated graphical waveform constantly with digital I/o

  I'm new to Labview and I try a digital waveforms graph to update in real time after the analysis of the data of a digital acquisition of data from input to output.  Is this possible or real time update can only be done with graphics?

  Hello

  Once, a very similar subject has been addressed in the forum of LabVIEW, where DFGray has responded to the following:

  1. You can use an XY graph generating X values yourself. This will ensure that you place the data exactly where you want it on the X axis. It's fast, but involves a cost of memory.
  2. You can use a chart of waveform with an entry of waveform instead of the cluster that you are using. Use the antiderivative of waveform to build instead of the bundler to make your waveform. Set the values of t0 on the appropriate values (negative work, as do the numbers - time is in seconds, using the primitive of timestamp to convert to DBL timestamp). Finally, you must set the graph of waveform to use the t0 values. Pop - up on the waveform graph and make sure that ignore the time information is not checked. Depending on your version of LabVIEW, you may need to appear on the chart or axis. When you uncheck ignore timestamp, you'll probably want to reformat the x-axis again. Waveform graph clears the data at each iteration, so you have to replot all your data every time. Just create an array of waveforms and keep to add. The t0s will waveforms in the right places. Yes, this can cause memory problems.
  3. Finally, you can use the waveform, that memory. Create waveforms as you did for the waveform chart and send them to the chart. He remembered what was sent to her from run to run. Make sure to set the length of the graphic history (pop up on the chart and select chart history length...) long enough to contain your data together. You can use a node property to retrieve the data at the end, if you wish.

• Draw text on the graphic waveform Plot

  I need to understand how to draw text on a waveform graph during execution. This could be a text box, a picture of the text, a label and an additional plot with text... etc.

  Yes, I know a graph would be better than this, but need to use a graphic for my application.

  The graph is updated every second, and new data are added to the history of the ranking. (Which means that the chart bigger every second) So if I draw the text above or behind the table, I'll have to update their location every second. I'll have to use card to XY Coords in an event, (mousedown or mouseup) to place the text (or image of the text) in the field where the user clicked.

  Step 1 to resolve this problem is to find first class, learn how to draw or text on the plot of the graph area.

  Does anyone have ideas of how this could be accomplished, or some ideas of a sneaky work around to make this work?

  Example:

  

  Unfortunately, graphics (graphic and graphic waveform XY) have support Annotation and slider, exposed programmatically through properties, but the array of waveform is not.

  What you could do is to place an indicator of 2D image that corresponds to the size of the chart above.  Make the value of the image that you draw be transparent and just print the text with transparent backgrounds.  However, I do not know the considerations on the performance of it - many times user interface elements, overlap (portions of even transparent) can cause problems of performance due to forcing redesigns... then again maybe a graph is always be redrawn in any case.

• How can I remove users from being able to clear history?

  I need to know how to lock preferences for the parameters of the story. I don't want users to be able to change the settings of the story and I already tried the local method - settings.js and mozill.cfg. But the settings don't not gray in the menu options once I put them and that's what I want. I know that my file is playing because I have other parameters that are shown in italics in the subject: config that I blocked. I'm using the wrong settings of the to do it eventually? Or is there another method that I need to use. I already followed all the 't' on this page: http://kb.mozillazine.org/Locking_preferences

  Here is my test mozilla.cfg file I created:

  Who you trying to change in the settings Option > privacy and you want to prevent others to change?

  You crashes only the settings in 'Clear history of Firefox closing' and not the main parameters.
  
  You can take a look to the topic: config page to see if it has affected prefs by activating / disabling the checkboxes.

  I don't know which have effect. privacy.item * Pref.
  
  The subject: config page shows only one for privacy.item.cookies and the source code makes clear to me also.

  I don't know why you want to include items such as sessions (active connections, basic authentication) used by FTP servers and disk cache and offline cache (offlineApps) application.
  
  People should be able to delete data in the event of problems and clear the cache and cookies must be one of them (we recommend a lot of times to clear the cache and cookies).
  
  Clears the form data and research should also be possible unless you disable save both passwords and form/search data.

  Note that only tools > Options > advanced tabs, then browser.preferences.privacy.selectedTabIndex will have no effect.

• Producer / consumer set loop of dynamic data item type

  Hey all,.

  I do a simple exercise of producer / consumer in a loop. In my loop of producer I audio Aqcuerir and in the loop of consumer I'm projecting on a chart

  Everything works as I had in mind, the only thing that bothers me is the way that I had to set the type of the element to the block "Get the tail" at the beginning.

  I knew no better way to get the kind of data that I used to just take an another "acquire its" Express VI and which hang. But that may not be the only way to get there, right?

  Note: I know that I might not need to use a producer / consumer design tend to do, but I need to get hold of technology for school work so I came with this exercise just to get a hang of it.

  Thanks in advance,

  Al.

  Al,

  You just need to feed the correct data type in this entry, which you did by getting the output of a second acquire its Express VI.

  You can also use the "Convert to Dynamic Data" function to do this.  When you drop to the bottom of the function, you will be asked to give the input type.  Tests I've done, it seems not to matter, but for example if you chose the entry to a single scalar type, you need to feed a digital constant (change to double type) in the entrance and use the output of dynamic data such as line item data.

  I don't like the dynamic data type because it is not very clear as to what it is.  Another thing you could do would be to use the "Convert from Dynamic Data" function to change the output of the VI of its acquisition to a different data type for more or less to avoid the original problem all together.

• How to change dynamic data

  Hello

  In my project, I use card PCI 6221.

  I can able to get data from a graphic design, DAQ card and save OK file.

  But I need to manipulate dynamic data before drawing the graph and backup in the file.

  I entered sensor, input voltage I need to edit as 10mv = 1unit. before writing to the file.

  How I can do this, any ideas please.

  Kind regards

• Medium-sized dynamic data analog input read DAQmx read

  Hi, I'm new to labview. Is there an easy way to index using the dynamics of data returned by a readout DAQmx x samples to calculate a moving average? My thought was to read the analog input for X samples pump with the data in another loop through the data, but I can't quite understand how index using the returned data set to extract the measurement value double returned for each sample.

  Any ideas on that?

  Thank you...

  If you get a type of waveform data, why did you ask on dynamic data? No, of course not would you use the conversion of dynamic data on a waveform.

  If you want only one channel, then your DAQmx Read could be changed to 1Chan NSamp. If your channel list only has one channel, you will get a table 1 d with a single element that can be indexed. To get the average of a waveform use the statistical function with the waveform. You use the average Point by Point, and not the average function that has a table for an entry.

  Make sure you always have context-sensitive help on. You can avoid many of these rookie mistakes simple.

• graphical waveform shortcut menu problems

  Hello

  We discovered a problem about shortcut menus on maps of waveform with our current installation of LV2009f2.

  In the development environment ("IDE"), we have created a larger application. In the display section, we have several graphics (waveform), where the user can select the signal traced by the contextual menu (aka the context menu). When running the application in the IDE so good, the menus are displayed with all of the elements, we have defined.

  So we have finished the debugging (so we thought) and created an executable. Then, we tested the executable on the same computer (the computer with IDE installed full). Everything if fine, context menus are shown as expected.

  So, we got to the next step in the creation of an installation package (which resulted in a size of 0.99 GB btw...). LabVIEW makes no complaints and we have installed this app (using the Installer) on a clean computer. No problems so far, our application has started, everything was fine. But then we tried to change the display: NO POPUPS! Instead, we had error 1165 (problems with Insert on the Menu, "Can't find the menu"). What happens here? Anyone with a clue? Where is my menu (reference)?

  OK, we had a second computer. Install this package of 0.99 GB too. From the app: just fine, except the missing context menus!

  More information:

  All computers are Windows XP, Service Pack, even. Context menus don't require no RTM file, so no missing additional files in the installation package. Menu references created by LabVIEW (IDE or RuntimeEngine [RTE]) on right mouse click on the control, so that there should be no problem with the benchmark missing or false. The values supplied to generate the menu are the same for the IDE and RTE, so no difference. The graphics are incorporated into a secondary, but still only had events for them, so we no problem. New: the reference for the menu is provided by LabVIEW (event "Activating the context menu", MenuRef), so it should be valid...

  Sorry, no example. It is difficult to reproduce, when it only happens to RTÉ and only on computers, where no IDE is installed...

  Tomorrow we will fill to the top of the VI for creating menu with a lot of debug message subVIs to check everything and everything is going on in there...

  Hi Norbert and others.:

  I found a solution for my problem (after a long session to create exe, deployment to a different computer, debugging and start all over again...).

  In deployments executable the shortcut menu for the chart is missing (and is missing only here!). So I first test a menu empty on each activation of the menu and create a new menu if necessary. To do this, you will need to turn off (disable) "default DURATION of the context menus" during the VI containing the graphic.

  A note more:

  All other paid (menus VI other) are loaded correctly, all loaded screws work dynamically. It's only the RTM shortcut missing... (And the RTM file is set to 'always include' in the application Builder!)

• Use the same graphical display of data from the different cases of event Structure

  Hello

  I would like one graph to view the input data and modified by one of the two cases of different event structure.  So if the event 1 is selected by the user, the data would be entered by the code contained in 1 case and then introduced in a waveform to display chart.  If the event case 2 is selected, similar data would enter the 2 cases but then displayed by the same graphic waveform , as in case 1.  I don't know if there is a way to do this... it seems that each case of the event would need its own array of waveform, but it becomes quickly heavy regarding the graphical interface for the multiple cases of event.

  Advice would be greatly appreciated!

  Thank you

  Mike
