How can i restart the VI without erasing the plotted graph

I have made a program  to plot a graph at a particular condition. But as soon as the program completes. when I restart the program the graph starts again , there is no older graph to be see. So. I want to change the program such that the pgraph starts plotting from the position it stops in the previous session. Please kindly help me.

Hi,
you need to store the data somewhere, a file on disc might be a good option.
When the program is stopped you save the current data to a file. On the start of the program you load the file and display the stored data...

    HOW CAN I RESTORE MY IPOD WITHOUT ERASING EVERYTHING?

    You cannot.
    That is what a restore does.  It erases everything and reinstalls the ios.
    If you are using the ipod as designed then everything is on your computer, so you can resync everything,  and you can restore from your backup to get the settings back.

  • For some reason every time I try to open iPhoto, it opens it but immediately it frozen. I can no do anything or see any of my pictures. How can I fix it? without erasing any of my pictures.

    For some reason every time I try to open iPhoto, it opens it but immediately it frozen. I can no do anything or see any of my pictures. How can I fix it? without erasing any of my pictures.

    What version of iPhoto?
    A. iPhoto '11. Version 9.4.2 (710.42)
    What version of the Operating System?
    A.Mac OS X Version 10.7.5
    What was I doing when the problem arose?
    A. I was uploading some pictures from my camera to my Mac then I closed it. next time tried to open it and it went right to the way that the pictire before shows.
    Did it ever work properly?
    A. It had some details; like taking a lot of time to send a picture from iPhoto to an e-mail or not send it at all.
    What steps have I tried already to solve the issue?
    A. None, I havent wanted to do anything to fix it because I'm afraid I could somehow delete my pictures. I know the pictures still there; because, they are on my screen saver changing and changing.
    I also want to know if there is any other way for me to see my pictures other than trought iPhoto?

  • How can I restart the phone?

    Updating ios failed and I can not restart my phone, the screen only shows symbol for connecting to iTunes - how can I restart the phone?
    Nor iTune or my computer can find the phone when connected to the usb

    Hey there susnil,
    It sounds like you have an image on the screen showing to connect the device to your computer with the usb cord but iTunes and the computer are not recognizing the iPhone. According to the following article you should choose one of these articles to help that depedning on your operating system:
    If you can't update or restore your iOS device
    http://support.apple.com/kb/ht1808
    If you don't see your device in iTunes, follow these steps for Mac or these for Windows.
    When you can see the device in iTunes, I would follow the same article to help with getting out of Recovery Mode.
    Thank you for using Apple Support Communities.
    All the very best,

  • How can i get the average graph?(DIAdem)

    hi,
    How can i get the average graph(2D-graph) of 10 measures?
    Can someone please help me?
    THX!!!

    Hello Charleen!
    If you want to do it programmatically have a look at the ChnAverage command in the help (see also StatBlockCalc for advanced calculations). Interactive you can use the statistic functions in the ANALYSIS device.

  • How can I make a waveform graph store the entire wave, not just the current time period and how can I save the actual graph?

    I am taking temp readings with a 4 channel DAQ, sending them to a waveform graph and exporting the data to excel, how do I manipulate the graph to take a continuous reading as opposed to losing the previous GUI and how can I save the entire graph?
    Using LabVIEW 2011 operating on Windows 7 professional. 

    That is the nature of the chart -- everything not in the history is lost (it is a FIFO buffer of length=1024 samples by default).
    The scroll bar is probably grayed out because you're show all of the data.
    Attached is a program that will add 5 random points to a graph and prompt you for a file location where to save a JPG snapshot of the graph.  It's not particularly good programming style, but it has all of the elements/concepts you're after.

  • How can I manage my music without erasing all of my songs?

    For reference I've had iPods since about 2005 and I've been through this many times. My harddrive in my computer recently crashed and I had to replace it. Now all of my songs are gone (other than the ones I got on iTunes obviously). About half of my music (near 500 songs) are off of old CD's that I have since thrown away since I figured I had them saved on my iPhone and my laptop. Reference again: I had this happen when I had an iPod touch also with another computer. With my iPod touch, I was free to manage my music manually without erasing all my songs that were on my iPod. Now why can't I seem to do this now with my iPhone. Please help! I can't loose 500 songs! That's $500 that I DON'T HAVE to spend on music that I've already bought! P.S. I just need to know how to manually manage my music without erasing all my music!

    is this the one you're looking for?

    if  I saw in SXMB_MONI.. the message was showing  (system error--  System Error - Restart is not possible... )   so, how can we  solve this issue..
    How can we restrt the  messages  from SXMB_MONI..
    Regards
    jain

    Hi Jain,
    You cant restart the synchronous messages nor u can restart it............Hence the messages regarding synchronous issues cant be solvable.....The only way you have is to Resend the same data by again posting it in the Outbound Folder (Outbound side or sender side).........So once the sychrouns message failed means then it is unslovable ......So just follow the above mentioned way of resending the data by posting in the Out folder......................
    Reward with points if helpful

    All iTunes content on your iPhone - all music, movies, tv shows, etc. and 3rd party apps should be in your iTunes library on your computer. Under no circumstances should any iTunes content on your iPhone be lost.

  • How can I restart the conversion process?

    When I installed I-tunes the program started converting my WMA files to the AAC format. I let it run all day but at the end of the day I had to shut down the computer, so I stopped the process figuring it would restart when I restarted the program the next day. It does not do that. The only way I can find to do the conversion is one album at a time. Is there a way to restart the automatic conversion process?
    Compaq Presario v5000   Windows XP  

    I don't know of an automated way to do it, but it is easy enough to do it yourself in one large batch. Note I use a Mac version of iTunes and still use iTunes6, but the following should be more or less the same anyway.
    Right click the headings in your library and you will get a pop up of all the different headings. Turn on "Type" by checking it. Type is a column showing the encoding method (e.g. AAC, MP3, AIFF, WAV, etc.). Now you can click on this heading to sort your library by encoded Type. So now all the WAV files should be grouped together. You can now easily select the entire batch of WAV files, right click, and pick "Convert to xxx" where xxx is the encoder type you currently have set in your preferences for importing files. So if it is not in the format you want, go to preferences and change it. Once you pick the Convert function it will convert all the selected files to the new format.
    Note that converting makes a copy leaving the original in place. So the other advantage of having the ability to sort and select a large number of files by Type is that you can also select all the WAV files to delete in one step after you have converted them all.

  • How can i restart the browser use a short cut?

    and it's so hard to find it in the menu...
    i think maybe you guys could make a setting searching bar, that's really useful.

    You can also use the restart command in the Developer Toolbar (Firefox/Tools > Web Developer;Shift+F2).

  • How can I change the plotting options in an xy-graph?

    I am trying to plot an xy-graph, such that the data points are plotted as circles and connected by lines that stay horizontal at the level of the data point and then go up vertically at the next datapoint. In the properties menu for xy-graphs this options is given. However, it is grayed out and I don't know how to activate it. Can anyone give me a clue as to why this is? I put a red rectangle around the options that I am referring to in the attached screenshot... Thank you!
    BTW: I am using LabVIEW 8.0.1

    I'm not sure why the Properties dialog does not allow you to select the Interpolation style.
    This is apparently a bug (verified for 8.0 and 8.2.1). It has been fixed in LabVIEW 8.5.1. Time to upgrade.
    (In any case, it is just a UI issue of the properties dialog box).
    One problem is the fact that you have little control over the circle size. You can increase the size by increasing the line width, which gets ugly quickly.
    If you want full control over the circles (color, size, linewidth), use the "plot images" overlay feature as in the attached example (bottom graph).
