Weird Timing In Chart

Hi there,
I'm trying to take data from a CDAQ card (which I'm simulating). It's an RTD, so I take the raw resistance and put it through an equation to get the actual temp values. I'm not sure if that is correct right now, but that's not a big problem.
The problem is that i'm trying to add multiple charts together so I can view multiple RTD temperature at one time. I have a single chart showing the output data, but when I put it into the chart showing the same data twice, something get's messed up.
I'm polling the data 100 times a second, so I have a scaling factor in the multiple chart of 0.01, and I have the offset in as the absolute time. When I run the VI I can see the time scale on the charts are not equal. I think the multiple chart is running about 2 times as fast. I'm not exactly sure where I've gone wrong here, but I sense there's a better way of doing what I'm doing.
Any help would be great.
Thanks.
Solved!

Not Working Graph.vi ‏92 KB

One of your charts gets timing embedded in the waveform datatype. What's the dt there? It will get lost once you only retain the y data as you do for the second chart
I also don't understand why you are constantly readjusting x0 (X scale offset) in one of the graphs based on the current time. That makes no sense! x0 should remain the same as data is added. Set it once when the loop starts.

  • Weird behaviour of chart axis in Numbers

    on the x-axis i entered three values: 12, 13, 16. But they end up being evenly spaced along the axis (I want there to be more space between 13&16 than 12&13).
    This seems absolutely illogical to me. Anyone has a fix? thx.

    This discussion is really useful. I was having the same problem with dates on the x-axis. The date values in my column of data are not equally spaced but they were on the chart when using a line chart. Now I am using a scatter chart things look better.
    However is it possible to join the dots in a scatter chart? For some data this makes no sense but the values on my x-axis are in order and so joining the dots here would. I really need a line chart that does not regard the x-axis as categories.
    Dare I say that I can do this in Excel!! In fact I converted an Excel spreadsheet to Numbers only to find the chart was displayed differently.

  • Weird Timing Issue with Custom Javascript Files

    I have attached a static javascript file to my application using the Shared Components...Static Files facility in APEX. This is working. I can call methods in my JavaScript file and they work as expected.
    The issue is that if I ever want to have JavaScript run when the page is loaded, it is as if the javascript is not in place yet when the method is called. For example, I want to set some some style characteristics of a few common fields that occur on more than one page, if I add a button to the page that I click to call the method (and don't select "Fire on Page Load"), this works fine. However, if I do select "Fire on Page Load", the javascript is invalid.
    I have tried After Refresh of the region which seems like it would work but, this event fires before* the javascript is available.
    How can I load the page, including the javascript reference, and then call the javascript method?

    WR,
    I think the latter, adding it to the template, sounds like the better solution. (I am using Application Express 4.1.1.00.23 BTW).
    Now for the newbie questions...
    I am trying to figure out exactly where to make this change. So, I had a couple of questions.
    1. I went into Shared Components>Templates. Then, I scrolled down to the section labelled Page. I see that the default checkmark is beside "No Tabs - Right Sidebar" so, I click this and I do indeed find a <HEAD> section defined. Is this where I need to add the reference to the javascript file?
    2. I assume I need to upload the static file to the server. Right now, I have uploaded it via the Shared Components>Static Files selection. When I add it now, I am doing this:
    var headElement = document.getElementsByTagName("head")[0];
    var currentCommonRiskPos = currentHeadHTML.indexOf( 'commonRisk.js', 0 );
    if ( currentCommonRiskPos == -1 )
       var jsRiskCommon = document.createElement( 'script' );
       jsRiskCommon.id = 'commonRisk.js';
       jsRiskCommon.setAttribute( "type","text/javascript" );
       jsRiskCommon.setAttribute("src", "#APP_IMAGES#commonRisk.js" );
       headElement.appendChild(jsRiskCommon);
    }See how I used "#APP_IMAGES#"? I am assuming that this would not work from the page template, correct? For example, in the template currently, I see:
    <script src="#IMAGE_PREFIX#themes/theme_24/js/4_1.js"></script>I am assuimng that I should upload my JS file somewhere in the images folder and reference it in the same way, right? For example:
    <script src="#IMAGE_PREFIX#JoesStuff/js/HellowWorld.js"></script>Does all of this sound correct?
    Thanks,

  • Weird timing issues when playing back a recorded sound file and with synths

    Hello there,
    I'm having a couple of strange issues with playing back files that I have recorded using MIDI data which is then used to play an external synth which then gets recorded to an audio track which at the time is perfectly synced to a click track.
    The problem is (and I really dont get why this is happening) when it comes to playing back the recorded audio file that sometimes it is either behind or ahead of the beat.
    This makes absolutely no sense because sometimes it IS in time with the beat and other times when I play through my piece it is obviously out! I haven't moved the audio file in the arrange window and it is a permanent .aiff file that is stored on my hard-drive...what on Earth is going on?
    On a side note, the same problem happens with any of Logic's synths when I use an LFO that is supposed to be synced to the beat. Sometimes when I play back the MIDI data it is perfectly synced and in time and other times it is horribly out. It really is just pot luck!
    Anyone got any ideas?

    Thank you supermacmom!
    I have the LifeProof case for the iPhone5, and I remember the instructions saying that any protective screen cover should be removed before enclosing the phone into the case, but I left mine on with no ill effects.
    But I should have taken off the back protective film, which was covering the video mic!

  • OS X Lion DMG and Java Issues

    I have a serious issue with my Lion installation.  In the process of upgrading from Snow Leopard through 10.7 to 10.7.1 to 10.7.2 somewhere in there, Java got badly broken.  I tried re-downloading Java for Lion and reinstalling but it gives me an idiot message that my OS version is not compatible.  ***?
    So I open the package with Pacifist and do an install to default location from the top of the package and all the Java stuff works again.  But then within about three days I can no longer open DMG files.  I double click them and nothing happens.  Disk utility won't launch.  If I reinstall the 10.7. combo update, Disk Utility works and DMG files open but if I try to connect to a streaming Java service such as used by Go To Webinar, I never get anywhere.  So I am at the point where I can either work with DMG files OR I can use Go To Webinar but not both.
    This is idiotic to me, but I cannot even begin to figure out why Java gets broken by applying an update and why my ability to work with DMG files keeps going away and if the two are actually related or there is just some weird timing juxtaposition. 
    Anyone who has seen this problem and figured out a solution, please wade in.
    Thanks!

    Well, the issue doesn't seem to be in your User since the Combo Update doesn't touch anything in your User Account. This being the case and assuming you have a backup of your account on another disk, I'd do a clean install of Lion. Then in Setup Assistant migrate over all your stuff.

  • Metadata not showing up (flash osx bug????)

    I have a problem that shows up intermittantly, for multiple folks on my team.  We've duplicated this only on OSX and in 10.1.85.3.  Occasionally for some of our movies (H.264 in mp4) the metadata packet doesn't show up (NetClient.onMetaData isn't fired).  We've saved tcpdumps and seen that the data is there.  We've seen this accross players (jwplayer, osmf, wowza simplevideoplayer).  We think that this is some weird timing problem.  Has anyone else seen this, any idea how to get past it?

    When exporting photos from lightroom on to my desktop, I am able to view all the Metadata information when "getting information". However, that information does not show up when the photos are exported into individual folders within the computer. I am exporting the files the exact same way, so I am not sure why the information is not appearing the same.
    I'm wondering if this isn't an operating system issue somehow, because it doesn't sound like anything Lightroom would do.
    Have you tried using an actual program to look inside your exports to see what metadata is there, instead of relying on the operating system to tell you? One such program is ExifTool, but there are many others.

  • Premiere Pro CC MXF problems

    Hi there,
    I'm currently working on Premiere Pro CC. We've imported all of our clips from our C300 from a hard drive that was shipped to us. The folder structure in intact and the clips have been working fine, up until now.
    I opened up my project today and I noticed a few clips were offline, they won't relink but instead give me a "generic error" message. The weird part is that there can be 2 clips from the same folder/file structure and one will work and one won't. Even weirder, we back up all of our media to two different folders. The folder we keep our working media on is getting thrown offline, the folder we archive everything... imports fine.
    We also noticed that, even though we imported from the Media Browser, the .mxf extension appears. This hasn't been the case in any of our other projects. It's a recent addition. Not sure if that's part of the problem but it's weirdly timed to our offline problem. It looks like we dragged our footage from the finder but we did not.
    Any ideas as to what's going on? One thought we had was that we recently upgraded to premiere 2014 but due to conversion issues and generally bugs, we decided to downgrade back to CC temporarily. We've completely uninstalled the 2014 suite and trashed all preferences.

    Hi Matt,
    I know that some other customers have complained about the quality of exports, as well. I have heard that 2 pass VBR might give bad quality. Can you try an encode with 1 Pass VBR instead? The quality should be just fine with 1 Pass VBR.
    Thanks,

  • ICloud calendar not showing on my computer

    I'm having a heck of a time trying to get my icloud to have matching data on my iphone and my mac laptop.
    I have 3 accounts.
    1 seems to have my contacts
    2 seems to have my calender
    3 has nothing.
    Not sure why I'm asked to have all these apple ID accounts for iCloud but I'd like to only have 1
    Question 1:  Is there a way to merge all the accounts so I only have to use one sign on name, one account,
    and have all my data floating around in my very own cloud?
    Question 2:  After I get all my info on one wittle cloud, how do I get that sucker to transport the data to both my iphone and my computer?
    Right now, I get one or the other on my phone, and only one at all times on my computer.  meaning I don't have any calender stuff and I'm
    a huge flake for appointments and interviews this week.    At one point it was all working - just stopped when i updated my iphone software
    and signed in with one of the icloud accounts and lost everything on my phone.  Weird timing and possibly just a coinsedence but still

  • Is there a way to move the playhead by a defined time?

    Ok, here is what I woud like to do in AA CS6:
    I want to create a macro (outside of AA) so I can place the playhead, click my macro button, move the playhead back by 3 seconds, then hit play (for a define 3 second duration) and then hit R (my hotkey for Record).
    My only holdup is that I can't find a way to move the playhead back by exactly 3 seconds.  Is there a way to do this in CS6?  Everything else I have worked out with the macro, I just can get the playhead to move exactly 3 seconds back. 
    It has to be exact or I will get weird timing.  I'm looking for a Cmd+Shift+something to bring up a "Move Playhead" dialog or something that I can put -3seconds into.  Thoughts?

    The only place in Audition that you can move the play head precisely is in the selection/view box at the bottom RHS of the edit window - this has six time selection boxes that you can input figures directly into, or you can drag the numbers with the mouse. The top left box will let you move the playhead to exactly where you want it - but there's no way to shift focus to the box within the keyboard shortcuts, I'm afraid.

  • Time zone and displayed time

    Hello experts,
    I see that in BW (or R/3 in general) there are many 'times' eg. system time, user time zone setting etc. Does anyone know what setting controls what time is displayed in the BW monitor? My screen shows very weird timing which is not true reflection of the actual time of data load.
    Regards,
    Ernesta

    Hallo
    BW show the system time which is the time of the Application Server.
    System --> Status --> system - time
    In the monitor you see the system time. Maybe you have some issue with buffer syncronization. Ask your basis team on this topic.
    I hope this can help you.

  • Strange new problem with external effects and latency compensation

    i'm currently facing a new , very strange problem with latency compensation for external effect devices. it alway worked fine for me but suddenly there are strange things going on. i'm suddenly running into problems when using sends which feed auxes going to external effect devices.
    latency compensation is set to ALL !!!
    easy setup :
    - open an empty project and create 2 audioinstrument tracks. on the first one load the exs with a drumkit and record f.e. a bassdrum pattern. leave the 2. instrument empty.
    - now on the first audio instrument create a send to bus 1 -> aux 1 and insert the i/o plug-in in the aux and route it to your external effect device. chose a temposynced delay.
    - press play = everything is fine when audioinstrument 1 is highlighted in the arrange.
    - press stop, click on the track with the 2. audioinstrument and press play = totaly weird timing problems. delay is only in sync when track 1 is highlighted.
    - create a send in the 2. audioinstrument and route it to bus 1 -> aux 1 too = still the same problem
    now insert ANY softwareinstrument in audioobject 2 and suddenly the timing for the delay is right.
    go ahead and create a 3. audioinstrument track but leave it empty first. chose it in the arrange = again weird timing problems with the external delay.
    insert any software instrument on audioinstrument 3 = still the same problem
    now create the send to bus 1 -> aux 1 in audioinstrument 3 and guess what, timing is right.
    *** is going on here ? can anyone reproduce that ?
    it works fine when using sends which feed auxes with software effects inserted.
    funny thing is, when i go to the environment and change aux object one to bus object 1 and insert the same i/o in it it works !!!
    very very strange, please tell me i'm not crasy and this is a bug !!!
    as said, latency compensation is set to all.
    i'm using the mac pro 3.2 8-core running os 10.5.4, logic 8.0.2 and a motu pci-e audio system.

    Welcome to the Discussions.
    If you need it formatted FAT32, reformat it on your Mac. Use MS-DOS (FAT32) as the file system. If you don't need it for both PC and Mac, format it HFS+ and you'll be able to use the Retrospect Express software that came with it on your Mac.

  • NQServer.log Timestamp is not matching with the Server/Machine timestamp?

  • Color Correcting a pulsing video

    I'm working with footage that must have had a strange light around. The skin tone pulses slowly... about every 5 seconds fading from red to pale.
    Any suggestion on filters that might make this less noticeable?

    Sophisticated application of the 3-way will allow you to build a matte that applies the filter to only specific areas. It's not easy to grasp but the manual has everything you need to know.
    The situation was caused by a metal or gas discharge luminaire that was using a 60 Htz power system and you were shooting at 1/60th-125th second. Even carefully examining a test tape might not have disclosed this weird timing artifact since you would have needed to review about 30 seconds of tape on a good monitor. But you don't want to do this again. can try to remember the lighting systems where you were shooting or go back and look at them. I often shoot under sodium vapor and some other high intensity discharge lamps in shops, garages, and plants. Wave your hand back and forth against a dark background and see if you perceive a strobe effect. If so, you must either kill those lamps or shoot at 1/30th second.

  • My notes aren't synced instantly between the iPhone and the icloud

    Once I enter a new note or update one on my iPhone it's not updated on the iCloud web interface, also when I do the same in the web interface I cant see it synced to my device and I don't know how much time needed to do that.
    What I have noticed is that my yesterday edits have been finally synced to my device today but I don't know in which basis this is working.

    Hey, OP here, asking this question appears to have fixed the problem. Magically. Weird timing, it's been doing it since yesterday and literally just stopped happening.
    So ignore this, I guess.

  • Pie chart legend summary bug, weird text being printed

    Hi guys, I created a simple report with a Pie Chart on VS2008 and on my computer the chart legend displays all items perfectly but when I deploy it on our web server the legend summary, which is always 100% doesn't say "Total" anymore but a weird text, have you seen this before? Here's a sample.
    On my machine the chart legend is the following:
    ITEM1                                35.0%    63
    ITEM2                                38.3%    69
    ITEM3                                26.7%    48
      Total                                  100.0%  180
    On the server:
    ITEM1                                35.0%    63
    ITEM2                                38.3%    69
    ITEM3                                26.7%    48
    eTotal:1_n_pseudoloc_   100.0%  180

    Have not seen this before, but do apply SP1 on your dev computer:
    https://smpdl.sap-ag.de/~sapidp/012002523100009351512008E/crbasic2008sp1.exe
    Recompile.
    And use SP1 runtime:
