• The XY graph Plot.LineWidth Property node problem

  Hello!

  I have a loop, where I repeatedly putting curves in a XY Chart. In the first iteration of the loop, after the first corner appears on the graph (I send data from the graphical indicator), I use a Plot.LineWidth Property node to align the thicker. However, in the next iteration, when the second plotted curve appears on the graph, and the property node is pulled again, the second curve remains thin. I guess what I've done wrong, that this property node defines only the first curve? How can I set the width of the line of all the curves of the XY graph on the same value? When I directly on the properties of XY graph, I can set the width of the curve, but only one by one...

  Suggestions how set the widths of the ground on a specific chart XY?

  Thank you!

  If it is a multiplot XY, you must set each plots properties by using the property activeplot (index of the new lot), then by setting the thickness.

• all the nodes property objects and objects grouped

  Hello

  Now position an on my GUI objects in the center of the screen using nodes property. However, I don't want to have to have a node property for each decoration, image and control. Is it possible that I can group all the objects and then use a property node to position them? I tried to use the property node all objects, but none of the clues seem to apply to my group of objects.

  Help please!

  Thank you very much.

  John

  p.s. I downloaded my vi test. The graph, the decoration and the exit button have been grouped. control over check.vi to set the object to be moved.

  Tabbed pages are a great way to group objects GUI.

  Rather than use a decoration,

  • use a tab control
  • Delete everything except the first tab
  • Hide tab
  • The value of the proprties of the tab control and control on this page is move, hide, display as well as the tab control.

  I hope this helps,

• Change the graph with nodes of property

  I've been struggling with this problem for a while now. I have a graph of simple waveform I want to set the horizontal scale to and then make a .png to file. The vi is attached. This vi is up to a lot more great vi. Does not work when I run the first level vi of the adjustment of the horizontal scale. The .png file I receive shows the unadjusted graph. However, if I open this vi and then run the first level vi it works - the graph shows the .png file scale properly. Also, if I just run this vi se it works correctly.

  I'm guessing there is a timing issue and the .png file is created before the scaling takes place, but I don't see how.

  Does anyone have any ideas as to why the scale does not if the vi is not open, when it is executed?

  If the front of the VI is not open, the nodes property can do nothing because they run in the UI thread.  This is consistent with the behavior you report with it works when the VI is open.

  Can you try to open the façade but putting off the screen (if the user does not see it) and then set the properties of the graph?

• overlap of XY graph with xscale property

  Hello

  I have a problem using the xscale maximum and minimum property... when I use the nodes property that it straddles two sets of curves in the same graph: one with the scale I put and the other as if I haven´t the value of the xscale assets... What I've done wrong? I Don t have a picture of what I m to describe because I can´t manage to get a screenshot with the two graphs are overlapped... = S... I hope you can help me... What can I do to remove the graph that doesn´t have a scale...? Thanks for your replies...!

  ... Lara Mia...

  Looks like you have several plots.  Check the property pages of the graph and see if all the plots are set to use the scales that you change.  If you have several scales and you want to change all then them you can use the active scale field, the scale property.

• Table & node property

  Hello

  I have a simple problem.

  On my side, I have a 2D chart.
  I can right click and exploitation of data > empty data to clear the table.

  I want to do this in my entry into force.

  If I do the node property or the local Variable with an empty array as input for my program initialization, it don 't work.
  They are therefore, any possibility of having a property node > data operation > empty table.

  In advance, thank you for your help

  Hey Mini,

  in your init framework you write empty tables to table three controls.

  When I test your VI it works as expected: all three paintings are deleted/erased...

  What else do you need?

  But as said before: you use two shift uninitialized registers. It would be really useful to initialize - using the same empty array constants!

• disable the node property problem

  Hi all!

  I want to do a VI that the user will not fool around with the button.

  So I put in my case for the "change the value" event, a node property disable during 1 second (disable) and out of it, an enable.

  The problem is that if I press the as button 3 times in 1 second, the button will still change the value 3 times, as he has memory.

  I want to just the user to be able to make changes to the value only after 1 second and not save them. I hope I made myself understood

  Are there any suggestions?

  You may use a state machine with two loops. UI loop place the actionwith a timestamp and the loop of consumer can compare timestamps to decide if enough time has passed, or if the action should be discarded.

• Nodes property RT for Typedefs

  I add a new feature to an application of the CR for which I would like to maintain scalability and flexibility by using a type of cluster definition. The cluster will represent the channels to use for a particular modular Subvi. I will reference this cluster in several places, and there's a chance I might need to add new items in the future, that's why I want to use a type definition (to apply the update in the world of the location of a file).

  I also need to be able to return the list of items in the cluster. Normally, I would do by accessing the Controls [] property, then through each control for the Label.Text for individual element names. Unfortunately, I can't access these properties on an RT target. [Well, I can if I run in the development environment, but not when compiled into an executable file] I understand that some nodes of property are not available on the objectives of the RT, but it is not clear to me who is and is not. For example, I often connect via remote façade panels, and I know that I can use the Visible? and nodes of property mode disabled on front panel controls (reading and writing) without problem, even if the position of NOR, it's that the front does not exist on the objectives of the RT. Why can I use these properties, but not as simple as controls [] and Label.Text?

  Also, anyone who has run in a similar situation and has found a way around it? It's a way to enjoy the benefits of the type definitions (which is globally set to day) for groups of channels on an RT target?

  Thanks for the explanation, Justin. It makes sense to instantiating a connection of façade (via the development environment) the impact to the target RT read some nodes of property. Or, at least I can see the logic behind it. I still think it would be nice if some properties might be available for the target of RT running without a connection to the front panel, provided that the reading of these properties will not affect determinism of the system...

  As for your suggestion of table, yes I totally agree with the concept. Except that - at least to my knowledge, it is not a good way to pre-populate the table in all instances. In other words, I want to have a list of predefined strings, defined as a type definition so that I can call from several screws and if I need to add / remove from the list at any time, I just need to change the definition of a type. Using, say, an array of strings, the best I can do is to use a control and change the default value. But would not be spread in all instances of control throughout the project.

  In general, I use an enum typedef to define lists of channel, and I have a little Subvi to go through each element of the enum (since I can not access the property names point []) to return a list of the elements in the chain. In this case, however, I wanted to have a little more flexibility: I want a typedef cluster whose elements are channel types and the entries of these elements specify the names of channel. Specifically, I work on a scalable CAN interface Subvi, which must be able to communicate with devices on several different manufacturers; for each device, I have a list of types of conventional channel which I will use for communication (set point, feedback, temperature - to be represented by elemnt cluster names), but each manufacturer has a different channel name ('SRA_Desired_Pos', 'SRA_Actual_Pos', 'SRA_Internal_Temp', etc - will be reflected in the value of the element of cluster chain) for each type.

  I was wondering if anyone out there has run into this kind of situation and find a clever way around it.

  "Well, that's a horse of a different color!"

  Just parse the descriptor type of the enum.

• Node property accessor vs LVOOP

  I spent my CLD and exploring the world of LVOOP.  I am a mechanical engineer with about 1.5 years of experience in LabVIEW, so I still have a ton to learn.

  While browsing through the LVOOP, I ran across things that I can't reconcile.

  When is the right time to create an accessor for a property of a class method and what is the right time just use a node property to get or set a node of class?

  Data class must have all children data parent instantiated inside more his own?  Or does just have its own data?  (that is, if the parent has child Name and Value, should he Name, Value and amount or quantity?)

  Can anyone provide an example of Composition as a class relationship?  I understand the LVOOP class training that the Composition is a "has - a" relationship, but I'm still not sure what this means in reality in the real world.

  Any help is appreciated.  Thank you

  Welcome to the object-oriented approach.

  When is the right time to create an accessor for a property of a class method and what is the right time just use a node property to get or set a node of class?

  I used to always create accessors and it is advisable to do so. Technically if the accessor is private (which means no VI outside the class can call) and you don't need to do any checking of range or any other logic on a read or a write and your class is not to have children, then you might get away with just using a ungroup by name (using a property node requires creating an accessor - the property node is just syntax to call the accessor).

  An accessor allows you to:

  1. the scope of access (i.e. which is able to access these data, data of class being always private in LabVIEW)
  2. error checking or conversion to centralize code
  3. protect code against changes how store you a value (as long as you can write an accessor which returns a value in the specified format, the way the value is stored internally to the class will not affect the rest of the application)
  4. have a single point to debug

  Data class must have all children data parent instantiated inside more his own?  Or does just have its own data?  (that is, if the parent has child Name and Value, should he Name, Value and amount or quantity?)

  Not if you use accessors to get data from parents. Because the child inherits all methods of parents, he can call the parents of the accessor methods. Recreate the fields Name and Value of the child class would be exactly what OO tries to avoid duplicate work.

  Can anyone provide an example of Composition as a class relationship?  I understand the LVOOP class training that the Composition is a "has - a" relationship, but I'm still not sure what this means in reality in the real world.

  Of course, take the job template DAQmx for example.  A task class contains information of calendar and 'a' one or more channels in. Each channel can be it's own class that represents the type of measure and scale for this specific channel information.  Given that the task class contains an array of classes of channels that have no use outside the context of a task, then you have a composition relationship.

  Hope this helps clear things

• TO RESET THE GRAPH AND TABLE SEQUENCE EVEN STRUCTURE IS NOT EXECUTED.

  Hello everyone, I made this vi which runs automatically at the beginning and I can't use my power butoon to control this vi. Now, I want to clear the table and graph vi even when the structure of sequence is not executed as the start/stop button. And I want also when I run the program both the graph and the table should be cleared. I tried a lot of things, but as I'm new to labview I can't do. Thanks in advance.

• Execution of Javascript different ESTK and Node.js

  I have this function to clean up text for the JSON output that simplifies the line different stream formats and escapes the quotes. So far, it worked fine, but now I've noticed that when ESTK and Node.js provide different output when it is executed with a change of line:

  • ESTK outputs '\n '.
  • Node.js outputs "\\n".

  
  

  That is the different treatment of the literal string gets, but don't know if it's the parsing Javascript or replace itself. Thoughts, ideas?

  sanitizeJsonText: {function (str)}

  return str.replace (/ \r\n/g, "\\n")

  Replace (/ \r/g, "\\n")

  Replace (/ \n/g, "\\n")

  Replace (/ \'/ g, "\'")

  Replace (/ \ "/ g," \ "");

  },

  Nevermind PBCAK. Question has been duplicated escapes into the branch of a code that was not used in ESTK that was matched debug printing behavior of duplicate code

• When creating collections and nodes via PHP setting is not the storage schema

  Hello!
  I am trying to create cat Collection and nodes with PHP backend.
  I use this setup as the basis for all nodes with small changes:

  static private $CHAT_CONFIGURATION = array(
     'accessModel'=>self::ROLE_VIEWER,
     'publishModel'=>self::ROLE_VIEWER,
     'persistItems'=>true,
     'modifyAnyItem'=>false,
     'userDependentItems'=>false,
     'sessionDependentItems'=>false,
     'itemStorageScheme'=>self::STORAGE_SCHEME_QUEUE,
     'allowPrivateMessages'=>false,
     'lazySubscription'=>false,
     'p2pDataMessaging'=>false
  );
  

  STORAGE_SCHEME_QUEUE = 1
  And this value has changed not for any node of hostory_ *.
  But when the node created I'm trying to use the chat and may not serve more than one value. Then I checked the configuration of the node from room console and found that this storage system has the value ITEM UNIQUE. When I changed it (using the room console) to TAIL cat began to work properly. How to set up the storage system correctly?
  Thank you!

  Well, I still don't know what it is.

  I tried your code and it works fine for me. After you run your 'createSession_chat' on a room newly created, I call getNodeConfiguration on the new nodes and that's what I get:

  -ALL-

  http_get: https://na2.collaboration.adobelivecycle.com:443/app/rtc? path = / chat_1/nodes/history/config print

  10.0 true false 1.0

  -PARTICIPANTS-

  http_get: https://na2.collaboration.adobelivecycle.com:443/app/rtc? quotes/configuration of the path = / chat_1/nodes/history_partic

  10.0 50.0 faux 1.0

  -HOSTS-

  http_get: https://na2.collaboration.adobelivecycle.com:443/app/rtc? path = / chat_1/history_hosts/nodes/configuration

  10.0 100.0 false 1.0

  -TYPING-

  http_get: https://na2.collaboration.adobelivecycle.com:443/app/rtc? ration = / chat_1/nodes/typing/adjustment path

  true 10.0 false 2.0 true

  ItemStorageScheme values match the values you used during the creation of nodes.

  Not sure what disaster happens with the Whiteboard because everything you showed us so far was connected to the nodes of cat, and I guess that I have no intention to proceed with changes to the PHP code since everything seems to work as specified.

• Hierarchical query, differentiate between the leafs and nodes?

  Hello
  
  I started coding a small program PL/SQL (not finished) with a hierarchical query:
  

  DECLARE
  
  CURSOR cur IS
  select 
    op_id||' '||op_descript as description, level
  from operations
  connect by prior op_id = op_parent_op_id
  start with op_id = 0;
  
  BEGIN
  
  HTP.prn('<ul id="arbre2" class="filetree">');
    for c in cur loop
      HTP.prn('<li><span class="folder">'||c.description||'</span></li>');
    end loop;
  
    HTP.prn('</ul>');
  END;

  This program must return a hierarchical HTML code like this (he does not at the moment):
  

  <ul id="arbre" class="filetree">
   <li><span class="folder">Folder 1</span>
    <ul>
     <li><span class="file">Item 1.1</span></li>
    </ul>
   </li>
   <li><span class="folder">Folder 2</span>
    <ul>
     <li><span class="folder">Subfolder 2.1</span>
      <ul>
       <li><span class="file">File 2.1.1</span></li>
       <li><span class="file">File 2.1.2</span></li>
      </ul>
     </li>
     <li><span class="file">File 2.2</span></li>
    </ul>
   </li>
   <li class="closed"><span class="folder">Folder 3 (closed at start)</span>
    <ul>
     <li><span class="file">File 3.1</span></li>
    </ul>
   </li>
   <li><span class="file">File 4</span></li>
  </ul>

  then jQuery will make a tree.
  
  But I don't know how to differentiate leafs and nodes in the request, to allow me to specify a class = 'file' or class = 'file '.
  
  Does anyone have a solution?
  
  A more general question might be: how to generate a hierarchical HTML code exactly as it is above my table operations (op_id, op_parent_op_id, descript).
  
  Thank you.
  
  Yann.
