Problem: XYGraph with units in one axis in LV7.0

When I bundle one array with units (length) and another without units
together into a cluster and wire it to an XY Graph, the unit label
shows up correctly at the lower-right corner of the X axis.
But when I rescale the unit by changing the unit label (from nm to
uin), the Y axis rescales as well! Furthermore, if I change the unit
label back to nm, the Y axis values to not revert back!
It seems that there is a problem when units are in only one axis of an
XY Graph. (I tried with units on both axis and that seems to work
fine).
Any solution/workaround?
Thanks,

Philip, I tried to post one, but there's something wrong with my ISP or
some other problem, so I cannot post.
But it's very easy to create: Make two array controls, one for the X
values and one for the Y values. Assign the unit nm to the X axis, and
leave the Y array without units. Make a new XY Graph control.
On the block diagram, bundle the two arrays and connect them to the XY
graph. Go back to the front panel and make "unit" visible in the
graph. A unit label will appear near the lower-right corner. Change m
to nm
Enter a couple of values in each to the two arrays.
Execute the VI. The points will plot on the graph. Now change the unit
lablel from nm to uin on the graph and then change it back. Watch the Y
axis go berserk.

  • Linear movement with 2 motors attached to one axis

    Hello,
    I have a PCI NI 7356 board to control the movement of two motors attached to one axis. This configuration is intended to have more power.  Each motor has its own encoder. I need the axis to turn to a specified position and return back to the initial position, it is a straight line move. There is no problem to do this with each of the motors separated, but if I try to make the two motors work together, the result is a clattering noise. It looks like the two motors are trying to do a slightly different movement.
    I tried two ways to program this: Master/slave (gearing one axis to the other axis) and sending the same position command to both the axis and starting them sychronised. In both cases the result is similar. I get this clattering noise for slow speeds and it dissapears once the axis gets to high speeds. 
    What can I try to get rid of this clattering noise?
    I plan to test how does it work if I put the same encoder signal for both the motors, intead of having one encoder at each motor? Should this improve behaviour?
    I think that the best solution would be to control one motor in position and send to the other its DAC output.  It this possible ? I am using the flexmotion library programing in C.
    Thank you

    The best option was to command the two motors separately. We could get
    rid of the clattering with the help of some mechanical adjustments.
    We are doing some tests with the device. Some straight line movements
    moving different loads.  It works OK until 20KN at 300rpm and
    acceleration of 1rpss but when we try a stright line movement with 22KN
    the device stops giving a following error. We wanted to test if it
    could move the the load, so we took the following error check off. We
    found the behaviour to be similar, but this time the following error
    bit is not set to 1.  I copy the axis state data of one test:

    The tests start OK, but after getting to 5.42 mm on the position (when
    the command was 200mm) the motor 2 goes to Off (pin 0) and then the
    motor 1. We don't understand why could this happen. The following error
    check has been dissabled and we see that the pin for it stays in 0, but
    why is the pin 0 set suddenly to 1?
    Thank you,

  • How to set a keyframe with setValueAtTime for only one axis?

    Hi,
    I´d like to set a keyframe for the layer´s scale, anchor point values but separately. Let´s say I want to add the following keyframes to a layer:
    time: 0, value: 100, axis: X
    time: 0.3, value: 10, axis: Y
    time: 1, value: 110, axis: X
    If I use setValueAtTime(time ,[x, y]) it always places a keyframe for both axis.
    How can I set a keyframe with setValueAtTime for only one axis?
    Regards,
    Thomas

    Dan, thanks for your fast reply. But the problem is a bit difficult to describe for a german like me
    I´m try to convert given keyframes from another application. Let me visually show how it handles keyframes that are set on different axis at different times:
    X: O---O---O
    Y: ---O--O-O
    You see when the user sets a keyframe and both axis were modified, both have a keyframe (see the last key). But if only one axis is transformed and the other not, there is only one keyframe. The problem that I try to solve is that AE is only able to set a keyframe for both axis at a given time. So if I set the 3 keyframes of the X axis first, the AE script will set keys on the Y axis simultaneously. That´s bad because it adds keyframe to the other axis where there is no value "cache". So if I would set all keyframes it would look like this:
    X: O--•O-•-O
    Y: •--O•-O-O
    The small dots indicate those "forced" in-between keys.
    So is there a "native" scripting way to separate the dimensions (like the position prop) for other props and add independent keyframes?

  • Problem with unit in Query

    Hallo Experts,
    We encounter a problem with unit in our Query.
    Szenario:
    We use the Unit like PC, SET in Query.
    In Table T006 those Units have value 0 in the field ANDEC, so they will be rounded up and rounded down in Query.
    Our Problem is some Queries need the rounding up and down but others don't need this function.
    Where and how should we change to solve the problem.
    thanks & Best regards

    hi,
    if you want to control the rounding off while unit conversion you can do it from SPRO
    In the BW system, goto SPRO -> SAP NetWeaver -> General Settings -> Check Units of Measurement -> Units of Measurement -> Choose the unit corresponding to 'KM' -> Click on 'Details' button in the toolbar.
    Look the field 'Decimal Pl rounding'. Change this to 3 or whatever value you choose and see if it works.
    in above link i have taken example of KM, you need need to select the required unit.
    let us know if this is solves your problem. I am not sure if this can be done for individual queries but this is controlled by UOM wise as mentioned above.
    Regards,
    Rk.

    Dear Linc,
    Thank you for the advice, John Blanchard1  and Linc Davis
    As suggested in your reference thread I removed "/Library/Printers/hp/PDEs/hpPostScriptPDE.plugin" and the problem has been resolved.
    I am guessing the the plug-in for the hp printers got corrupted and effected every thing, or became unsuitable when I installed an Apple update. I would be most grateful if you can confirm how the problem was coursed so I can understand and learn from this experiance.

    Welcome to the Apple community.
    If you are unable to remember your password, security questions, don’t have access to your rescue address or are unable to reset your password for whatever reason, your only option is to contact Apple ID Support, upon speaking to an operator you should explain that your problem is related to your Apple ID, this way you will not be charged for assistance, even if you don’t have an AppleCare plan.
    The operator will take you through some steps you may have already tried, however they need to be sure they have exhausted all usual approaches before trying to reset your account, so you should try to be helpful and show patience with the procedure.
    The operator will need to verify they are speaking to the account holder and may ask you some questions that only the account holder could know, and you will need to answer them if the process is to proceed.
    Once the operator has verified your identity they will send a message through to your device which contains an alpha numeric code, which you will need to read back to them.
    Once this has been completed they will send an email to your iCloud email address after a period of 24 hours, so you should check that mail is enabled in your devices iCloud settings.
    Upon receipt of the email, use the reset link provided to reset your password, after which you should be able to make the adjustments to iCloud that you wish to do.

    Anything you downloaded with the first Apple Id will forever be tied to it, and will always require it to update.
    The question here is, why did you think you needed to create a new Apple ID? What was the problem with the first one?
    To get rid of th old one, you'll need to delete everything you downloaded with it, and then sign out of the ID in several places around the iPad. 
    Go to Settings->iTunes & App Stores->Apple ID->Sign out.
    Repeat the process, for Facetime, Messages, Mail and any other App you need to sign out of.

  • My ipod touch broke then replaced it with a new one. I already dloaded iOS5 on the old one. When I connected my new unit it says it won't load the previous back because the new one is not up to date... Do I really have to download iOS5 again?

    Yes, you have to update the iPod in order to retore from backup. The iOS on the "new" has to be aequal to r greater than on the iPod from which the backup was made.  The iOS downloads are unique to an iDevice and model (the one for a 3G iPod will not work for a 4G iPod).

  • I have created a site with iWeb. I have replaced the iWeb Nav bar with a vertical one I made myself. Problem is, my top button disables itself if it overlaps into the "hidden" nav bar area. I can cmd click and drag it into this area, but then all the rest

    I have created a site with iWeb. I have replaced the iWeb Nav bar with a vertical one I made myself. Problem is, my top button disables itself (and the animation doesn't work) if it overlaps into the "hidden" nav bar area (indicated by a blue rectangle). I can cmd click and drag it into this area, but then all the rest of my site is pushed down the page. Don't know what to do about this. I don't know how to bring the rest of the page up without dragging it also into the designated nav bar area. Also, by doing this, is it affecting my site in ant way? see my site here at www.steveburrowsimages.com
    The home page is with it all draged into the nav bar area and the about page is with is outside the nav bar area (notice that the top button does not animate or work as a button.
    Getting confused here. Anyone got any ideas?

    Well, you made a good start with SEO by getting rid of the iWeb default navigation since it doesn't help the spiders and, out there in the real world, there are more people than you would think with javascript turned off in their browsers.
    One of the downsides of iWeb is that it doesn't allow for the alt attribute in the img tag. Its well worth adding these to give you extra keywords even if you have captioned all your images. Use iWeb SEO Tool for this...
    http://www.iwebformusicians.com/Search-Engine-Optimization/Tags.html
    iWeb, just like most drag and drop software, creates a huge amount of code which causes the pages to load slowly in the browser. Running you files through an optimizer will help to reduce this problem and further reduce the size of image files even beyond the initial optimization you do before loading them into iWeb...

  • Problem with more than one item in a track

    DVDSP 4.0.2 / OSX.4.2 I've built a DVD with several tracks. In each track I've placed several .m2v files, one after another. Finished build plays fine on my Mac and on one of my stand alone DVD players. But on another stand alone (Sony DVP-S360) something very odd happens. DVD begins to play just fine, but whenever it encounters a track with more than one source file, it will play until it gets to the spot in the program where the second source file is in the track and then it hangs and won't do anything. I'm just curious if anyone has any insight into this problem. Is it a DVDSP conflict thing with certain players? Or is this Sony player just not capable of playing a DVD built this way? Thanks.

    This page here:
    http://www.videohelp.com/dvdplayers.php?DVDnameid=428&Search=Search&
    has someone talking about finally getting burned DVDs to work, which suggests they previously had problems. I can't think why the track would not seem like continuous video, as if it had always been that way. Our Sony DVD player at work seems sensitive to higher data rates. What data rate did you use?

    Eg:
    In SPRO, I am able to see the unit of measure T3 Description: (Trading unit).  in SAP 200 client .the logon language is EN(english).
    But if I logon into same client(200) with different language DE(german) version, I am not able to see the description in German, the description field is blank.
    Kindly give me a solution for this problem as it is very urgent.

    Hi Aishwarya,
    I can think of 2 possibilities:
    1. You need to verify passing the Target UoM with the ISO Code as well as the update flag in the 'X' structures.
    2. The material that you are trying to pass some UoM does not have the conversion maintained in the Material Master. (Base UoM --> Target UoM conversion in Material Master, contact Functional Consultant).
    Also, if you can verify by performing the action manually and check if the Sales Order is getting created manually with the Target UoM .
