XY Buffer for 2 points

I am trying to plot two counter vales (acquired one point at a time from a DAQ card). Using a single XY-Buffer works well, but I cannot seem to show both counters in a single plot. Can someone tell me how I solve this problem.
On the same question, is there any advantage in using a XY buffer over a (shift-register + Build Array) combination.
A screen shot of what works and what does not is shown below.

OK, found it.
The xy-buffer is not intended to buffer multiple plots, just multiple points for a single plot. The array input is used if there are multiple points added at once to a single plot.
What you need to do is buffer each plot separately, then build the array for the multi-plot using "build cluster array". See e.g. XY-Chart C or D in the quoted example.
The XY-buffer is reentrant, thus can be used multiple times, each with its own data.

  • Return vector for points done of check buffer status in onboard program

    Background
    I am trying to develop a trigger application based on the current position of a contour profile.
    I can not use breakpoints as the application is using hydraulic cylinders with analog feedback
    for the primary position. In order to make sure the trigger happens relative to the motion regardless
    of host load I want to run the application as an onboard program.
    My idea is to read the buffer status points done and generate a pulse out as a trigger when the
    points done is greater than the programmed trigger point. For example if I want to trigger on the 42
    point of a 100 point profile, I would read points done of the main contour buffer. When points done
    is greater than or equal to 42, I would generate a short pulse as a trigger.
    Question
    My problem is, I cannot find the order that the check buffer status VI returns the data to an onboard program
    return vector. As I understand it, I need 3 variables to hold the returned data. One each for State, Backlog, and
    Points Done. If I set the return vector to 10, does State get stored in 10, Backlog in 11, and Points done in 12, or
    is there a different order?
    If you could provide the return vector mapping order for all the motion VIs, it would be greatly appreciated.

    Hello,
    This is a very good question. I checked in the help for the LabVIEW VI, and it does not explicitly state the answer. The VI calls the FlexMotion function "flx_check_buffer_rtn". In the "NI-Motion Function Help" (Start>>Programs>>National Instruments>>NI Motion>>Documentation), the information for the functions states that it "...returns data in the following order: backlog, bufferState, and pointsDone." It also tells you the size of each of the elements. I will be filing a report so that the LabVIEW documentation includes this information in the future. I hope this helps. Take care!

  • Update error: POL - 4008 null buffer for attribute is not allowed

    I am attempting to update a column in my Oracle Lite database through JDBC.
    The statement is:
    ds = getDataSource();
    conn = getConnection(ds);
    stmt = getStatement(conn);
    int results = stmt.executeUpdate("UPDATE SYSTEM.PM_PASSENGERS SET CURRENT_STATUS_EVENT_ID = 267 WHERE PASSENGER_ID = 1");
    System.out.println(results+" rows affected.");
    conn.commit();
    which results in the message:
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    1 rows affected.
    [POL-4008] null buffer for attribute is not allowed
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    I am not sure what that means exactly. Does that mean there is some problem with the commit?
    Thanks,
    Allen

    Is it necessary to update the entire record in Oracle Lite, or should it be possible to update select columns only when performing an update query?
    Thanks,

  • Mac upgrade to Yosemite, Adobe Indesign CS5 keyboard shortcuts not working -  t for text  - z for zoom - v for pointer etc

    So I upgraded my MACBOOK PRO (Retina, Mid 2012) 2.7 Ghz Intel Core i7
    to MAC OS X YOSEMITE
    Adobe Indesign CS5 generally works with some very annoying bugs.
    All major keyboard shortcuts that use a single key command have stopped working. and these happen to be the main ones I use all the time for editing...
    t for text
    z for zoom
    v for pointer
    It's annoying because now I have to keep  going back to the tool bar to change my cursor selection. It's just slowing me down.
    Annoying but workable.
    Has anyone else go this issue?
    An update or fix would be greatly appreciated.

    WARNING!!!
    I was contacted by  apparently a third party supplier called Adobe Systems via this forum
    They logged in to my computer via team viewer
    installed utorrent
    and proceed to download a cracked version of adobe cs6
    in the mean time saying on skype that Adobe no longer has Adobe CS6 on their server.
    This seemed very OFF to me and I disconnected the skype (and blocked Adobe Systems) and disconnected TeamViewer
    If I wanted a cracked version of Adobe CS6 I'm very capable of doing this kind of thing my self
    However I run a business I want to have a legitimate licensed copy of the software running for my staff.
    They were offering a fully licensed version of a Adobe Master Suite CS6 with my own unique ID for USD$400
    Again very OFF considering the upgrade from Adobe from Indesign CS5 to CS6 is almost AUD$1600
    I don't know how they got my email address from this forum but it seems that the adobe forum has been hacked!
    you have been warned!

  • How about two SDN "blogspaces" : one FOR points  and 1 NOT FOR points ?

    I suggest that the current SDN logspace be divided into two subspaces:
    one for points: this is where technical and/or non-controversial messages would be posted and be rewarded according to the current rules
    one not for points: this is where folks would post "controversial" messages (technical or non-technical) that would not get any point reward.
    I would personally prefer to post in the "not for points" subspace, for several reasons.
    But I'd prefer to see what others have to say before saying what they are.
    By the way, there's a US expression "preaching to the choir".  The new blog (for no points) would be for those who are not necessarily "preaching to the choir".

    david,
    i think i do understand your intention and therefore agree with you.
    IMHO, the blogsphere here on SDN, as execellent as it is, is kind of a 'posing platform' rather than a discussion space. People do post their contributions, receive their points reward and expect some congratulations and cheering if anything at all. I happened to me that people got upset when I questioned the use or correctness or usefulness of some of the content of their blogs. When it did this with the intention to discuss matters, I recognized that people actually didn't want to discuss their contributions.
    Of course the things said above do not hold true for for a big number of contributors.
    The same thing thing in the forums. A lot of people do provide very valuable answers but often not discuss matters when points are already given.
    So having a discussion area, free of the rewards system's pressures might be a helpful addition. Something like a discussions corner. In Vienna we call this 'Kaffeehaus'
    A place where you post some free thought where you don't have to justify the minimum blog reward points, where you don't have to apply the care expected in drafting a blog, etc..
    Just freestyle discussion on useful or not so useful topics.

  • WLC code for point to point bridging

    What is the best WLC code for point to point and point to multipoint bridging on a 2504 with 2602 APs? 7.2-7.4 had transparent vlan issues and I'm not sure if they were fixed in 7.5-7.6. We have 5-6 vlans that we are needing to bridge between a large open area. Also, are there any bugs with wireless mesh and ISE?

    You do not have many choices now, only 7.0.250.0, 7.4.121.0 & 7.6.110.0 codes are supported by Cisco. All other codes have been deferred by them.
    I do not have configured those set-up to advise you specific to that. I would think 7.6.110.0 may have fixed whatever the known bugs in previous versions.

  • Do we need ask for points

    Hi friends,
    one more chance to share my latest query..... when i first started into this forum i used to request for points after answering questions....  But since a long time i dropped this idea since the poster of the question anyway knows and has the responsibility to reward based on the merit of the answers.
    So, in such case how much fair / required it is again to ask for points. ....My intention is how can we give balance to content and not just worry so much about points-
    And its bit painful to see people who ask questions which require spoon feeding some times say that Points will be definitely rewarded to attract : as if we would answer anything for points.
    at the end of my query i thought the correct subject of my question would be why do we need to ask for points
    Your opinions please.....
    Best Regards,
    Sadhu Kishore

    Sadhu:
    Thanks a lot for this post! -:D
    Here's my explanation...People just don't read...They still think that they are going to get some free T-Shirts by gaining points on SCN...They think that they're going to get better jobs or that they're going to have better reputation...
    Nothing farther from the truth...Points are only good for the Food for People program...Nothing more...And I would love to think that people want to contribute to this wonderful program...But I'm not that naive -;)
    I have crossed the 10K milestone...Why? Just because it was a personal goal...And because I get points for writing blogs and posting answers to the forums...But of course...I have never asked for them...
    People must understand that this is a professional community...That we're are doing this because we love SAP (Ok...At least I love SAP)...
    To me ask for points it's like give something to charity and say "Say thanks otherwise I get my stuff and get out of here"...Very bad behavior...
    Points are not going to go...They exists for a reason and I wanted them to stay...People must change...And change for good...

  • BI Content for Point of sales( POS) module in retail

    Dear Srinivas,
    I've already run a systemtrace to find out the tables:
    The following tables are involved: MPOS, MMPT, MPLA and MHIO, MHIS.
    In BI-Content I just find MPOS in the DataSource 0PM_MAINTPOS_ATTR and 0PM_MAINTPOS_TEXT. That is ok for master data.
    The other tables I couldn't find in BI-Content.
    But maybe the BI-Content does not use these tables. Maybe there is used a view which I don't see in the trace.

    Hi Paul,
    I'm looking forward to hearing you work the term "fancy hat" into an explanation of this behavior.
    I get the same behavior on 11.2.0.2. Tsk tsk on you for not mentioning your version. Back on 10.2.0.4 the same select statements yield:
    ORA-06531: Reference to uninitialized collection
    ORA-06512: at "MDSYS.SDO_UTIL", line 344
    So the only nuance I can think of, which isn't really a nuance at all, is that getnumvertices isn't allowed for point types.

  • Firewall necessary for Point to Point internet connections?

    Firewall necessary for Point to Point internet connections? We have multiple point to point t1 connections to our sites and was wondering if a firewall should be in place to filter traffic. We are also implenting a microwave t1 from a service provider and was wondering if firewalls would be needed for just this or the wired as well. According to the microwave company no firewalls are needed. Do i really want to leave security in the hands of the ISP?

    Matt,
    If you are buying private line T1 service from a carrier that connects 2 of your sites you would not use a firewall. Your traffic is never mixed with any other traffic. If your data is very sensitive, or if you have to comply with Payment Card Industry standards then you might want to encrypt your data, but a firewall would still not be necessary.
    If you have a T1 connecting you to the Internet for Web browsing etc then you very much do need a firewall.
    Please rate helpful posts.

    Hello Prashant,
    I recommend to use LACP instead of unconditional bundling it provides the capability to detect the neighbor and that is the same system connected to the other link.
    You have ISP connections in the middle and so it is important to bundle in a safe way.
    So I would use
    channel-group 1 mode active
    in order to use LACP. LACP messages are sent over every member link.
    Another point of attention is that you are configuring each multilayer switch with a static default route to the other device and this is not good practice.
    If you know that one site is more important you can configure the static default route on the other router, but on the main site you should configure specific static routes describing the IP subnets that are reachable at the other site.
    Hope to help

  • Questions to moderators: is begging for points eligible to moderation?

    Hello mods,
    posted that outside of the RA thread, so that it be noticed and debated.
    In a topic ({thread:id=2296311}) posted in the Community Feedback forum, OTN regulars voice against begging for points ("Please mark my answer as helpful/correct").
    One of them even points to a "Posting Guidelines" post ({message:id=9698382}) (I don't know whether it's a copy of whatever official OTN posting guidelines page) that suggests moderators are allowed to edit out such point-begging posts.
    I have noticed such begging lately, including from respected and otherwise helpful regulars.
    - What is the community's opinion about points begging?
    - What is the moderator's point of view about moderating it out? I've never seen that applied here - I don't know how busy you are with the existing duty already, been away for a while.

This topic just reminded me some deviant behavior beheld here lately.
    The rest of it is a discussion by real regulars about the inanity of the points system and of the forum software ;-)As usual on that forum, yes :o) It's quite hard to convince them that the same harshly-bashed Jive software was working fine on the late Sun forums.

I'm a moderator and I've never been aware of such a guideline in general.
    And I certainly don't go around editing posts wholesale, life's too short.Fair enough.

    - What is the moderator's point of view about moderating it out? I've never seen that applied here - I don't know how busy you are with the existing duty already, been away for a while.My opinion is that I really couldn't care less about points begging. The moderators have more important things to do than go looking for trivia like this, such as work, and real moderation, i.e. of offensive or irrelevant content. But in general if a post has no useful content, it is noise, and therefore probably eligible for deletion. If you find such a post you are welcome to report it in the 'Report Abuse' thread where the moderators will at least see it.Note taken. Case closed.
