How do I manually update a graph/chart

I have a chart on my front panel in which the data is continuously being changed.  Each loop cycle (few seconds each) I clear the chart history (property node), update the chart data, and then change the Chart range to the range that it previously had.  However every time I do this I can see (for less then half a second) the clear chart and then some segment of the new data before it shows the correct data range that I want.  Is there a way to delay graph from updating until I signal it to update so I do not see the intermediary garbage data?
Thanks in advance,
David

Look for the Defer Panel updates property node.  Set it to True before you do the other properties and False After.
But if you have the need to set the range back to a value it was before, it sounds like you might have the axes set for autoscaling. ??  You may want to turn that off.

    Connect the iPod to your computer and update via iTunes.

  • This is a question for all my adobe applications in the CS6 suite. How do i manually update them? I have not gotten any updates in about 6 months and they are running really slow. I really think this is the issue. How can i do this?

    I am a full sail university film student and I need all my adobe applications running strong. Everything is running slow and sluggish. I think this might be the issue. Does anyone know how to manually update the adobe Cs6?

    What does your computer's sluggishness have to do with any potentially missing updates? That's pretty much nonsense. The last AE update was the 11.0.4 one from November, anyway, and it's only relevant for Mac people more or less. Whatever issues you have have nothing to do with that but rather poor system configuration and maintenance - fragmented cache disks, disks almost full with temp files, too many other processes/ programs running and gobbling up resources, aggressive external tools like virus scanners blocking access to files and functions and so on. Really, you are completely looking in the wrong place. Bring your computer up to speed and AE will run a lot better.

  • How to get mouse properties from Graphs/Charts?

    Hello,
    My problem is the following:
    I have a graph that displays some data and two cursors.
    Next to it is a button that allows users to select whether
    they want to see all data, or a selection based on the
    cursors. When in the selection mode, the cursor can be
    dragged to change the data shown, but the graph is updated
    while dragging. I wanted to make a simple wait-while-mouse-down
    call, but this seems to be more complex than I imagined.
    I know the example that uses the picture frame to get the mouse
    properties, but the picture frame blocks cursor usage. Is there
    another solution to my problem?

    Hello,
    The best way to achief this is using an event structure to capture a mouse button up. I have changed your program in a way that it uses an event structure to look at the waveformgraph. As soon as a mousebutton up occurs, it stops the while loop where it is waiting in and updates the graph according to the new currsor settings.

  • How can I manually update videos while all else is on auto-sync?

    Please forgive me for asking this again, but I need to free some much needed HD space on my MacBook Pro, so I want to get rid of the videos in iTunes without deleting them from my iPod, normally done via the manual update setting. But I do like the auto-sync of everything else (music, photos, etc.).
    Can this be done?
    Thanks for helping!

  • How do I manually update a Silverlight OOB client?

    Hello,
    I have a Lightswitch Silverlight client app that has been up and running for about three years now, regularly updated. Up until now, the server that housed it was in the same office as my dev machine, and thanks to a lot of help from Garth Henderson, we
    got it so that I could publish remotely from Visual Studio.
    Now the server has been moved to another office, and I don't have the same access to it. I tried using Visual Studio as before, but it errored out when deploying, claiming that it couldn't log on to the database. I know the user name and password are correct,
    so I guess this must be due to lack of access to the database from outside the local network. I don't have authority to open up the database to the outside world (nor would I want to!), so it looks like this idea is out.
    I tried creating a disk package, so I could copy it to the machine and deploy it manually. I tried following
    the instructions here, but when I selected the zipped package, I got an error...
    An error occurred when performing this operation.
    Details:
    Could not find the provider 'LightSwitchApplication'. Please verify that you've entered the provider name correctly.
    I have searched around, but not found an answer to this.
    What I would really like to do is just copy over the changed files, but when I tried that, I got an error about not being able to update the app due to the installed application and update candidate differing in certificate/signature state. I think this
    is probably my fault, as when I was creating the disk package, I noticed that the certificate was about to expire, so I generated another. I guess I may have changed too much at once. I've tried uninstalling and reinstalling, but that didn't help.
    Anyone able to help? I really need to update this app, but can't. Thanks

  • How to generate an s-curve graph/chart in labview

    I would like to generate my s-curve shape in a visible graph in a labview vi. Are there any quick/dirty vi's that can take position, accel/decel, vel and jerk value, and plot this into a time graph? Something akin Motion Assistant...
    I am able to construct a trapazoid graph using basic algebra within lab view, but cannot find a good formula to compute an s-curve. I am familiar with converting the jerk value to actual counts/s^3, but from there on, I do not know how NI-Motion calculates to accel, decel and velocity times. Thanks.

    Hello,
    What versions of LabVIEW and Motion Assistant are you using? Motion Assistant 1.2 exposes its API to LabVIEW and these functions can be accessed by opening LabVIEW and navigating to All Functions >> NI Measurements >> Motion >> Motion Assistant. Using these VIs, you can set up a move and use the Get Move Profile VI to obtain an array of points for the velocity profile.
    Beyond this method, there is no straightforward way to obtain those datapoints.
    If you have any questions about this method, please let me know.

  • How do I manually update a contact with their Facebook?

    I signed on in settings into Facebook, I also have my Facebook app up to date.
    My contacts list correctly synced about 40% of my contacts with the correct Facebook account - with their profile picture etc.
    One contact is incorrect, I have no idea how that happened, their names and profiles are totally different.
    The problem is now that I'm trying to update my phone contacts with their Facebook counterpart it simply won't work.
    If I type in say John Smith it won't find the person, if I go to their Facebook page and find out the username eg john.smith.9 it still won't work, I tried going back into settings and updating contacts but still nothing?!
    Any help would be greatly appreciated. I don't want to download 500 Facebook 'friends' just to update the ones in my phone book so I get their profile pic etc.
    Thanks

  • How can I manually update email.

    Is there a way to update email when roaming or when on cellular? 

    No different from updating email when connected to an available wi-fi network.
    If the email account supports push access for received email, no manual check is required.
    If the email account does not support push access and you have Fetch set to automatically check the account or accounts automatically, the accounts will be checked for new email in the background automatically.
    You can manually check an account or accounts the same as any other time.
