multi parcels

Hello

I'm programming a PID temperature controller and must draw two curves on the same graph. The first is the desired temperature - a straight line - and the other is the fluctuating temperature depending on the time. Missing VI configures the serial port, set the PID values and get the current temerautre. They all have been tested and work fine. Any suggestions?

You have some major problems with the path you draw. First, you use a XY chart so that you only get a single parcel. If you want to trace two separate, then you should use a regular graph or chart. Second, the way in which you create the table with the GetTemp VI is completely false. At each iteration of the while loop, you create a new item of a table and replace. You throw the old data. The simplest thing for you to do is to use a chart. Wire the scalar of the ReadTemp and a constant to a bunle function and the release of what the graph.

  • How can I update a single parcel in multi graphic of xy trace?

    Hi all

    I'm working on a 'before' HMI for a larger acquisition/analysis system, which includes monitoring the continuous performance of a turbine. The results of the measurements are stored arrays of contour lines, which represents the openings of turbine efficiency and guide of pallets. This analysis is all running in the background. In the GUI, performance data are loaded from file when the specific report' is requested and is plotted in a XY Chart. I would like to indicate the current operation of the machine using a pitch which is a single point. So a position of this point among the contour lines indicates the current performance of the turbine. This point is updated once per second, while performance data remain the same for considerable amounts of time between recalculations (days or weeks).

    Is it possible to update the value from a single source in a conspiracy of several XY graph without having to redraw all parcels?

    I tried to use the 'Active Plot' property, which does not work.

    My current solution is to keep all the input data to the execution of the while loop and replace a subset of table plot, but which of course requires the entire rewrite whenever the plot of operating point is updated.

    You can't redraw a single parcel. If you want to update a single parcel, you must keep all parcels in a shift that and replace the desired field data. However, your problem seems much simpler than that. To display a single point on a ground almost static, you have several options.

    1. You can use a cursor that is controlled by program (the style can be a point, do not allow to drag).
    2. You can use annotations.
    3. You can use the "plot images" feature which allows you to use the picture controls to draw anything on top a chart.

    None of these ideas need a refresh of the data.

    I think that the idea of cursor is probably the easiest and most appropriate. Just use a node of property with the following properties:

    • active cursor
    • cursor x position
    • cursor position y

  • problem with marking albums multi disc

    In the past when I have an album that has say 3 CD, I was able to right click > get information, then place the disc 1 of 3, 2, 3 and 3/3. In my case music files would then appear as 1-01, 02-1 right through the first disc and the 2-01, 2-02 and so on.

    Now, I do the same with itunes 12 but in the folder it now appears as the title of the 01 01 title song, 01 song title then 02... It does not differentiate which is drive 1, 2 or 3. Is it possible to go back to the old way to do.

    You'll be amazed how much multi discs, I have...

    Any help appreciated

    Let iTunes do file management and don't worry in this regard. Your only interaction with your files either through the iTunes interface, where questions of multi-disc are correctly identified.

  • When Fire Fox support (again!) for display of multi column (and navagable) Favorites (bookmarks)?

    I always use rev 31. This is the last version that is compatible with the add-in on, "Multicolumn Bookmarks 1.5', I have several brands of books collected over the years and the single column format is frustrating and not helpful."

    Asked to provide a current version, which is compatible with "MultiColumn Bookmarks 1.5' Fire Fox, or provide a favorite navigable multi-column as option display in a near future program revision Fire Fox.»

    Sorry, to complete the thought:

    (1) install Stylish from the Mozilla Add-ons site

    (2) then back to the user page of style to get the style (the button should be green instead of blue right here)

  • How can I get multi channel audio via the HDMI port on an early 2015 MacBook Pro?

    I try to get the 7.1 audio channels to flow from my MacBook Pro to a cinema set up. The display works fine now I plug the HDMI in however the sound still Mac speakers. I checked the settings and no HDMI output is available. An airtime option is available, but that returns only two channels as a maximum to the receiver. When I go to the configuration of the source on the receiver it receives video at 1080 p 60herts however it is specifically stated No Audio from the Source.

    Also, I have connected my iPhone 6 s more using an Apple through the same HDMI cable adapter and it works perfectly. We also use HDMI with our PS4 occasionally and it works perfectly, even with the 3D.

    Thus, the MacBook Pro is early 2015 with an i5, the receiver is a Harmon Kardon AVR 2700 (we run 7.1 channels of this) and we are connecting via the HDMI port through a 50 ft HDMI before. The receiver sends the audio to a projector with 1080 p 60 hertz if it changes anything...

    Also if it helps the receiver supports dts - hd master audio decoding, Dolby True HD/Digital Plus decoding, HDMI 1.4 (HDMI is compatible 2.0), as well as multi-channel input and PCM and linear PCM.

    I use a "Behringer UCA202' audio device I bought on amazon.com for only $29.

    It works very well for the audio 5.1 or 7.2. Works connect optical toslink. Just plug it into a usb port on your Mac and a cable optical toslink to your AV receiver.

    My Yahmaha 7.2 audio/video receiver is measuring process the digital signal in THX, DTS, Dolby digital Pro logic, a cinema, etc.

  • How to preserve the multi-level iPhoto in Photos folder directory

    If you upgrade OS to Yosemite or El Capitan, how to preserve my folder customized Photos iPhoto multi-level directory? My iPhoto library is 105 GB and contains 41 000 photos, all carefully arranged in a directory of custom and subsidiary subjects.

    iPhoto (the beloved and only) has a great power in its ability to custom folders full of full of albums etc. subfolders directories several levels deep, with photos that can be duplicated in different albums, folder & file size info, etc. Unless this can all be kept in the Photos, there is no point me upgrading until Apple gets serious on the needs of demanding photographers, who want the custom control and want as their stuff protected in their hard drive and not on the cloud. Automatically generated 'events' and 'albums' are things of grandmother-and-the-children, useless for people like me. I need a custom control over making inventories of multiple folder levels based on my own custom categories, categories or undated events Apple thinks we should have. Home, school, family, travel, etc. just does not cut it!

    Someone really aware with this situation can help me get clarity? Promo stuff on pictures Apple responds to virtually none of my questions.

    I would like to begin by asking in the forum of Photos, but until you do, you need to specify your terminology. iPhoto offers events, Albums, and smart Albums for the organization. Thus, by "directories" I can only imagine say you you have files of records nested within other folders? If so, you can do with Photos. There is no need to use the features of cloud Photos. They are not mandatory in any mode.

    Regarding your comment, if you're a serious photographer why you use iPhoto? Make sure you used Apple app for photographers, it was called Aperture. Now for photographers you use applications 3rd party - Lightroom, Capture One etc.

  • Multi-port USB adapter for the MacBook USB - C Port?

    Hello

    I'm in pain, trying to find a USB adapter multi-port for my MacBook 2016, which only has a single port USB - C which is also like a power port.

    I already done is connect the WD My Passport drive external HARD to the MacBook via an adapter HooToo, that to see any HARD drive mounted in OS X.

    OS X makes a sound when it is connected, but apparently the adapter provides insufficient power for the HARD drive needs to be loaded.

    I got Belkin USB multi-port here:

    http://www.Apple.com/us/search/USB-ports?SEL=accessories & src = SERP

    But it is not certain if one of them provides enough power, so I would try rather than a person has used successfully with a MacBook and an external HARD drive,

    If not, opt for a multi-port adapter USB brand Apple.

    Please let me know about your experience or an Apple adapter.

    Thanks in advance

    My Apple 3 port works as advertised. The USB port has a perfect compatibility with the old and readers USB 3, my adapter Ethernet USB Apple and Trendnet USB adapter that I use in series. This includes the perfect function with a 10 VM Windows via VMware Fusion.

    A non - Apple C to an adapter that I bought works fine too. I don't see the brand on this subject but he chose via Amazon ratings. There were some with higher ratings, so that's how I made the choice.

  • a separate album multi disc set

    I can't for the life of me, see why a created disc multi disc shows separately for the album.

    This is the Portrait of Dan Fogelberg, 4 CD set. I did read the information and changed the orinal separated from 4 albums at all with the same name.

    Deleted "Disc X" in the title of the album. So disks 1,3,4 now appear under an album for the album, but disk 2 shows upward in a separate album.

    What's funny, is that if I go to the windows folder, the MP3 from all 4 disks are in the same folder. Watched a lot of attributes through windows Explorer

    and they all seem compatible. I also did the same Album artist for all. Any other ideas? I even deleted and ripped out again to see if that would clean things up.

    Im running the latest update of iTunes in Windows 7, if that matters,

    Thanks for all the ideas.

    I had a similar problem recently... try to remove the title of the album of all disks, so you get the artist with the unknown album, then readd the title of the album.  Worked for me
