Line Chart - Is there any Example?

Hello Friends;
I searched through old messages but I couldn't find any servlet example which produces a line chart. There is a "free" API called JFreeChart . They initially put some examples in the free distribution but later on they removed. They sell the user guide which has lots of examples for $40 bucks, which is not affordable for students like me.
Sometimes small examples explain a lot to a beginner level user.
If you have anything that you can share, it would be appreciated.

Ok. No problem, I found some applet examples, I'll try to put them in a servlet.
There shouldn't be any problem, right?

  • Is there any  example snippet for XPath using namespace

    Hi,
    I have used XpathApi class to get the XML node matching my xpath that does not deal with namespaces and it works for me. However, it does not seem to work well when I construct the xpath with namespaces (probably I may be doing something wrong example: //ns:node1/@ns:attr1).
    Can anyone give pointers or some example snippet or some links to handle Xpath with namespaces.
    Also if there is any better approach (Classes or framework) for handing XPath with namespaces then please let me know.
    Thanks,

  • Are there any examples of queres or reports for the Access DB TS can generate?

    I am currently useing the default TestStand SPC database storage routine to store the results of all runs. Are there any tools, queries, reports, etc. to help me post process this database? I thought I would check here before making something myself. Mainly looking for something that will do a scatter plot for a certian test so I can see where all the data is falling within the limits.

    Currently NI does not have any post processing tools to assist you in formating the result information specifically for TestStand databases. Obviously using LabVIEW or LW/CVI or some other programming language you could write your own program to do such post processing.

  • Is there any example for a software transceiver in labview / labview modulation toolkit ?

    hi everyone
    i am sure you have heard of this a lot ..... but i am new (like 20 minutes old) to labview. i am quite fimiliar with matlab and other programming languages. i am doing a project based on software defined radio. for that i understood an example demo from matlab where a fully functional software transceiver has been built as an example.
    now i myself have to do that in labview for the sake of comparison and better real time compatibility with USRPs. i am just getting started and was hopping if there is a similar example in labview or someone else's project. i have installed the modulation toolkit and have gone through its various blocks. i understand that i can build a tranmitter and receiver from scratch but that would take a lot of time and testing. so can anyone help me out in any way.....?

  • Is there any examples for VB as the "Cont Acq-Int Clk" for ANSI C?

    I wanna acquire  continuous datas using the USB-6008 in VB , but I can't find how to use "EveryNCallback" in VB!
     there is any way to acquire  datas continuing for real time computing in VB?
    Thinks!

    The device can return a set of samples after a amount of sampling(at least 1000 times, that's enough), namely at a longer time.
    Maybe there is RAM in the device which I didn't find on the user guide & specifications.
    Well.Now I have known the bottleneck is the slow reaction of PC.\(^o^)/
    The examples of VB still doesn't work. its parameters settings show in the picture.
    If I set the Sample Rate above 300Hz it show that msgbox after seconds ,if below 300Hz, it can work longer, .
    And if I set like this:
    it can work well,even the Sample Rate up to 10kHz.
    Wait for anyone who can settle this.
    Thanks for your patient help,NIhuyu!

  • I want to use the MXCTRLLib functions from VB. Are there any examples?

    I have tried
    '* place a reference to the max library first
    dim aa as mxConfiguration
    set aa = new mxconfiguration
    aa.invokeMAX ' starts a MAX session
    'aa.invokecreatenewwizard(0,"test") = "help" 'starts the wizard for a new channel
    The above code starts MAX interface running. There seems to be several function for reading and writing configurations. Does anyone have some examples?
    I want to be able to read each channel and get it's name and scaling so my app can be set up properly if another engineer changes or adds a channel.
    I also want to be able to setup a configuration very fast on a new computer. I know I can save the config... but creating the config is a pain w
    hen dealing with large quantities of analog and digital signals. MAX does not seem to be able to handle the load. I am thinking of a seperate interface that acts more like a database where I can sort the channels by SCXI board and channel number OR by name.
    To see these functions add a 'reference in VB to National Instruments MaxCTRL 1.0. After that you can use the object browser on MXCTRLLib to see all of the functions.

    Megan -
    I have attached an example that returns only the data that falls between the X max & min labels. If you zoom in on a particular portion, the data that is returned is only the data that falls within your zoomed X axis.
    Hope this is of some help.

  • Are there any example vi's for implementing a circular buffer between a plc, opc server, and labview dsc??

    I am storing a block of data inside plc registers and reading this group into labview as a continuous set of datapoints. I am counting the number of scans in the plc and sometimes the number of points collected inside labview doesn't match.

    To explain a a little bit about tag updating:
    The LabVIEW DSC tag engine is not just updated on any change of the value within the plc. There are, in fact, several "deadbands" that must be crossed before those tags are updated:
    1) The OPC Server has a deadband - where the plc register value has to change a certain % before it is recorded.
    2) In the LabVIEW DSC moduel, there is an I/O Group Deadband that determines when the tag engine is actually updated.
    Both of these deadbands must be satisfied before a new "value" is recorded in the LabVIEW DSC tag engine.
    Therefore, I would check your OPC Server's deadband (configurable in the OPC Server configuration utility) and also the I/O Group deadband for those tags (configurable in the tag configuration
    editor).
    If this doesn't resolve the issue, please let me know. Thanks.

  • Are there any example CVI certification exams available from NI ?

    Thanks for any insight, -Dean

    Am I going to be asked what menu or submenu to use to launch a certain feature ? I have no idea, I just look until I find it !
    Will there be an instance of CVI running that I can use during the exam ? ( e.g. if I'm asked a question similar to what I stated above, or to use the help feature ). I was also curious if there was a practical part to the exam, which you stated there was, that was big question I had, so thanks agin for the input.
    Even better: you will be asked what happens in case of error if you debugging level is "standard" or "extended" and so on...
    Based on my experience, you will need to study carefully at least the Programmer's reference.
    My exam had nothing to do with DAQ, DDE, Datasocket, ActiveX and generally external devices / programs: I don't think this aspect has changed, but it should be clear in the documentation available for the exam.
    Fortunately, you will have a pc with CVI installed to work on, since in the same 4-hour block you will have to answer questions and develop the application in no particular order, but consider that it's no long a time if you need to study the online help to answer
    Proud to use LW/CVI from 3.1 on.

  • Are there any examples for programmatically creating OBR 11g rules?

    I am looking for some examples about how to use the API to create rules from Java code as the SDK documentation is very terse. Are there examples out there for creating rules?

    When you create items in IB, they always appear at a default size (table view cells and nav bars have a height of 44, etc.). Is there anywhere to access these constants in code, for when you are creating elements programmatically?
    Not that I know of.
    When I want the default dimensions for IB Library objects, I generally drag the objects of interest out of the Library, and read the dimensions manually in the Size Inspector. In fact, when I want to create a view programmatically, I often lay it out in IB, then use the Size inspector to get the frame of each subview.

  • Are there any examples that do not require a personal webserver?  I do not need a server for my aps.

    Back when Cirrus was Stratus, there was no need for a personal webserver to host a CGI script.
    I have no need for a non AS3 server because my server is simply going to be another peer node on the network
    It is a professional way to handle things too:
    1) You have a computer with a static IP that computers refer to as the master peer(yes wordplay).
    2)If you can't afford a computer with a static IP, you can simply create a peer that responds to requests,"Are you the server?"  Yes, this is easily hackable, but when you're debugging, your friends aren't gonna be jerks.
    All I want when I contact Cirrus is:
    1) A list of IP addresses of connected peers.
    And if someone has example code:
    2) The ability to send "Hello World" to all peers.
    Is this doable in Cirrus?  Stratus could do it.

    the only difference between "Stratus" and "Cirrus (codename)" is the name.
    Cirrus has never had a "list connected peers" function, nor has it ever reported IP addresses/port numbers of connected peers in ActionScript.
    the VideoPhoneLabs example program has always required some kind of external registration service to register a peer ID for a name, and to look up the peer ID for a name.
    it's possible to do P2P with Cirrus and no active web server by using RTMFP Groups (NetGroup, GroupSpecifier and friends). i have posted examples from my labs at MAX from years past that implement text chat and other functions using only Cirrus. and you can do P2P with groups on a LAN with no server at all (not even Cirrus).  see this thread:
       http://forums.adobe.com/thread/766959
    for links to my lab materials from MAX 2009 and 2010. and come to my session at MAX this year where i'll be covering "Advanced P2P With RTMFP: Tips & Tricks".

  • Is there any example code to send a message from Service Broker to ActiveMQ?

    I would appreciate any links or discussion on this. I have found a number of similar questions but no definitive answer that it can be done. There is a .NET interface to ActiveMQ so maybe the answer is a C# CLR procedure to get this done.
    Thanks
    Tom

    Hi Thomas,
    A C# CLR procedure sounds like a fitting solution, since basically what you need is to access some program external to SQL Server.
    Note that doing so will require you to create an UNSAFE assembly within SQL Server, and probably also set the database as TRUSTWORTHY. These are serious security risks and not recommended unless there's no other choice.
    A more secure solution would be to have some .NET application that accesses your Service Broker queue (instead of an automatic reader handling procedure), and programmatically sends its contents to the ActiveMQ. This is essentially a 3rd party component
    that would need to be developed.
    I hope that helps

  • If I want to make a single-frame importer, e.g. - for WebP image format, do I need to implement an SDK importer plugin? Are there any examples?

    The title says it all really. Was wondering if there's a simpler interface to implement which does not contain video or audio, but just a still frame image.
    I don't care about exporting this format from Premiere, just being able to read a single frame or a sequence of frames to be used as footage.

    Hi Rotem,
    A standard importer plug-in is the way to go for a still image importer.  You could start from SDK_File_Import in the SDK.  There is also a WebM plug-in on GitHub:
