• Remove parcel of legend of plot in LV 2011

  Hello

  With LV 2011 it is now possible to use a check mark in the legend of the plot to hide/show a conspiracy. I'm running a problem though: I can't Remove all legend points to "old plots" once that they are added.

  

  As in the image above, I traced a first set of data created on 6 channels: 3 "tones" and 3 "old channels. If sbsequently I only send to the plot 3 'tones', I can't get rid of the old channels. I tried to use the properties of the legend, but they in deca. Any idea? THX.

  Laurent

  THX Chris for the pointer

  Criterion VI is re-bound here.

  It's kind of what I was describing, but it is a bit of a trick to make it work. If you stop the VI and expand the legend of old plots are still there. But I'm cherry picking.

  PS: Page 2 this forum is actually here with more discussion on the subject.

• How to customize the context menu in the legend of plotting the graph of wave?

  I am currently on the creation of a simulation of various control loops as educational objectives. Here, I have a chart in waveform to different signals. Now my question, how to customize the context menu in the track of the Waveform graph legend => when I click on 'image' behind the Plotnames one menu to open options where you can customize the color etc. or plotwidth. But students should not have access to these settings. How can I change or disable this menu? The context menu for the waveform graph, I've already customized by right click on table of waveform-Advanced online-online menu, but for the legend of conspiracy, I have not found this setting...

  Thanks for your answers... I tried different things, but I don't see a solution yet :-(

  See you soon

  Hi, STC,

  There have been a number of suggestions for change or disable the table , right-click menu, but I see that this does not affect the context menu of legend , which is what you ask for help with.

  To prevent completely the menu right-click to work, you must disable the chart control entirely. You can do this by double-clicking on the chart and select Advanced Options > active state > disabled. This will prevent the operator to be able to generate a menu right click on the chart control.

  If however you still wanted the table, make a right click menu to work, but the legend made a right-click menu will be disabled, I see two options:

  1. draw a classic decoration square on the legend and the transparent color. This will prevent the mouse clicks to achieve the legend, and transparent it will not interfere with your user interface appearance.

  2 use a Structure of the event to capture the event filter Popup Menu of Activation?  for the chart control. You can then use the Coords property to determine if the mouse is over the legend or not. If this is the case, send faithful away? right Terminal. It will refuse the context menu when the user clicks on the legend of the plot.

• Export of legend to the screenshot

  Hello

  I am trying to create a screenshot to my graphic option. Including the legend. It seems pretty good so far:

  Public Sub ScreenShot()
  
          {
  
              Limits of Rect = LayoutInformation.GetLayoutSlot (SensorPanelGraph);
  
              var bitmap = new RenderTargetBitmap ((int) limits.) Width, (int) limits. Height, 96, 96, PixelFormats.Pbgra32);
  
  Rect bounds2 = LayoutInformation.GetLayoutSlot (mainWindow.SPSMI8Legend);
  DrawingVisual dv = new DrawingVisual();
  using (DrawingContext dc = dv. RenderOpen())
  
              {
  VisualBrush vb = new VisualBrush (SensorPanelGraph);
  VisualBrush vb2 = new VisualBrush (mainWindow.SPSMI8Legend);
  Origo point = new focus();
  
                  Point LegendOrigo = new focus();
  
                  Point LegendSecondPoint = new focus();
  LegendOrigo.X = origo. X + limits. Width - bounds2. Width - 5;
  
                  LegendOrigo.Y = origo. Y + 10;
  LegendSecondPoint.X = LegendOrigo.X + bounds2. Width;
  
                  LegendSecondPoint.Y = LegendOrigo.Y + bounds2. Height;
  DC. DrawRectangle (vb, null, new Rect (origo, bounds. Size));
  vB2. Transform = new ScaleTransform (0.75, 0.75, LegendOrigo.X + bounds2.) Width / 2, LegendOrigo.Y + bounds2. Height/2);
  
                  DC. DrawRectangle (vb2, null, new Rect (LegendOrigo, LegendSecondPoint));
  }
  bitmap image. Render (DV);
  path access String = Environment.GetFolderPath (Environment.SpecialFolder.MyPictures) + @ "\Graph.png";
  
              using (FileStream outStream = new FileStream (path, FileMode.Create))
  
              {
  PngBitmapEncoder enc = new PngBitmapEncoder();
  ENC. Frames.Add (BitmapFrame.Create (bitmap));
  ENC. Save (outStream);
  }
  
          }

  I know that the code is not beautiful, I'm still only experimentig autour however. My main problem is the following.

  The legend has not much room on the GUI, so it sets itself automatically scroll horizontally and vertically on the window if I fill it too. Unfortunately, the VisualBrush object takes a copy pixel by pixel of the UI object, and the exported image, I see only part of the legend that was visible at the time of the screenshot and scrollbars on each side.

  Question: Is it possible to copy all of the legend, as if it had grown to its full size?

  All WPF drawing mechanisms use the size of the layout of the control. To view the complete legend, you will either need to expand the legend in the user interface, or you do not have to use the technique of the question rendering bitmap WPF create item off-screen (of Alex + ra) to do off the screen.

  To develop the legend, it is possible to measure and organize using the desired size of the legend (although this will change on the screen):

  Rect desiredBounds = new Rect( new Point( ), legend.DesiredSize );

    legend.InvalidateMeasure( );

    legend.Measure( desiredBounds.Size );

    legend.Arrange( desiredBounds );

    legend.UpdateLayout( );

  To update off the screen, you'll either need to remove the legend of its parent and measure then as above, or create a new legend with the same settings make.

  Another alternative would be to declare two legends in your UI, one of them now in a hidden canvas (allowing him to full size without the screen on). This would avoid the need to measure and arrange calls to update the page layout (although Visual legend would be silently updated even when you do not use the screenshot feature) manually.

• Legend field size changes when the cursor moved legend

  So weird, I don't even thought it, but here it is:

  In VI attached, I have legends of the parcel next graphics, if I can put checkboxes next to them for the turning on or off the channel display.  In the third, I need to include the sliders, but when I did the legend of cursor visible and moved (it automatically appears on the side, under where I put the legend of the plot), the legend of plot in size changes.  It is shortened, which is annoying, but also means that it is more aligned with the checkboxes.

  I tried to use the PlotLegend:Height property and managed to _read_ it is, indeed, evolution, but I can't put it (or rather, I can't do it to _stay_ together).

  Even more strange: when I open the file on my laptop, the problem of size change does not occur, BUT the legend of the plot begins with a different size of the boxes!  I know that I can use 'Objects to scale with the Panel', but I've always shied away from that, due to problems of size and text beside it, since I am defining the size of the Panel, things really should be the same size, anyway.

  Because of the issue of the different-monitor-size different, I don't know if the version of the file's "modified" screen will show the problem, but I have attached, in the case.

  Any ideas?

  specifications that might matter:

  Desk at work: machine card Dell with Windows7 64 bit AMD Radeon HD7470 graphics LabVIEW 2012 SP1

  laptop at home: Dell Latitude E5430

  Thank you!

  Well, it's certainly weird - it does on my PC as well. I have no explanation for it.

  Perhaps a solution you can use the checkboxes in the visibility field integrated instead. You wouldn't need a separate control.

  Right click on the legend of the plot and select 'Visible Elements' > 'plot visibility Checkbox.

• 6 curves 3 plots stacked tracing?

  I have a few filtered x, y coordinates z which I currently plot to a waveform with plots stacked chart. How can I include data not filtered on the respective plots?

  That is to say. 1 x route view filtered and unfiltered together, is filtered and unfiltered together etc.

  

  Hey Graham,.

  Interesting question! It took me a while to understand, but it is certainly possible - even if the solution is a bit a violin.

  

  Please see the attached code. To impliment your feature, I had to...

  • Group all plots (in this case 4) into a single cluster, and send in a graph "stacked."
  • Resize the legend of plot to show all 4 locations.
  • Right-click on each item in the legend, navigate to The Y scale , and then select which window you want to show the plot (1-4)

  This means that 2 of the windows will display 2 plots of each, and 2 windows will be empty. Unfortunately, I was unable to 'hide' a window - so that's where the "Violin" comes from - I just resized and repositioned each of the 'windows' to effectively only showing 2 of them in our stacked chart.

  I hope this has been helpful Graham,.

• How to copy an a refnum xygraph is - a?

  Normally it's simple enough to get my own.

  Purpose:

  Col Refnum XY graph for Subvi-->

  Purpose of Subvi: PRINT XYGRAPH to file/pdf/bmp, manipulate the xy graph more (back ground color change to leaving for printing, leaving graph xy for printing size, move the legend), perform simple analyses on the data (rms, pkp etc.)

  Problem statements:

  1 when you use a refnum, any change in writing refnums property value will also change the parent, i.e. the Subvi xygraph.  This is not desired, then an exact copy of the xygraph must be made.  HOW DO YOU DO THAT?

  2 when you use a refnum for a xygraph, how do we get the xy values?  If the value property node is selected, a variant is produced.  (which, after careful examination, I was still not able to make heads or tales of this particular variant)

  PS a refnum is used because the xygraph was already formatting applied to its legend, axis, plots, etc.  A refnum passed to a Subvi is the only way I know to succeed all formatting etc. for the chart.

  PPS. I understand that there is an invoke node that will export an image, it contains certain restrictions (for example, requiring that the Subvi be open, because it works by rules similar to a print) which make the United Nations applicable to this problem.

  You must use the variant data to convert the variant into the native data.  XY charts can take data in several formats, so you can simply create a constant to your XY graph, dump all the data to get the appropriate format.

• Want to read the size of a graphics window

  I would like to use the size of the graphics window to position the legend next to her, but cannot find the right property. "Bounds - width area" seem to include the entire control (blue arrows in the image below) included the legend, while 'Plot - region - size' seems to be that the area of the grid (yellow arrows). What I want to know is the size of the box which includes the plot and labels of axis (red arrows). Anyone knows what are the properties would get me this information?

  

  Way is the simplest steps.

  1 set the visible property of the legend to false.

  2 get the limits

  3. set the caption to the visible and move as you want.

• Graph plot legend colors Signal not updated when mixed with the property node

  Hello

  We try to put the colors of the trace of a graph of Mixed Signal using a property node. Although we can change the color of the data in the field correctly, the colours of the plot in the legend do not change until some apparently unrelated operator action is performed (for example, to resize the window or by double-clicking a field name).  Waveform to XY charts don't seem to have this problem.

  Anyone know a work around?  I think I saw a similar topic on the forums earlier, but I'm sorry that I am unable to find it now

  See attached vi.

  Thank you

  -john

  I should probably have joined the last post of VI, but I have has been a thread of error between the two loops.  I also deleted the text you had so I could see the I need to press the button.

• Legend of the plot does not update?

  My legend of conspiracy will not show the new names I'm wiring. It displays the default plot 0, track 1, and so on, rather than the column headers it is supposed to read the data file.

  Any ideas? See the attached VI and the associated text file that I am trying to trace.

  In the example you have validated, your table for the colors of the plot is empty if the because the loop will not run.

• Can I detect a change of name of plot event in a legend of the plot?

  I want to update a configuration file, if a user changes the name of a conspiracy in the plot legend.

  Events, I see plots are: value change, the change of range autoscale, plot attribute change and change of range of scale.

  Change of attribute plot doesn't seem to understand anything like on behalf of the parcel, and others obviously do not contain this info either.

  Is it possible to recover this event?

  Thank you.

  Jordan

  First of all, remember that there is no simple way to encode anything, so I can offer a possible solution for you, but it certainly isn't the only one.

  LabVIEW has no property to check if the name has been changed through a structure of the event, but you can create your own LabVIEW can read events. I found this really good which may help you. Read this and mess around with it and see if it gets you anywhere: Creation of user events

  Once you get to trigger the appropriate, then its just get this deal to update the file you want.

  Another possible workaround solution that isn't ideal, is to create a chain control and who have to be on top of the name of the parcel. You would be able to produce then an event in this chain, change the value.

  I hope this helps.

• Rotate the Plot chart legend of XY

  Is it possible to rotate the legend of the plot for the plot names letters run from the bottom to the top rather than in the whole of the operator interface?

  The names of my plots are bigger and I need to show at least four plots at the same time. Put the scales to the right/left/above or below without rotating can cause a short XY Chart!

  Any ideas for me?

  Concerning

  Waris K

  Hello

  I don't know if there is a native way to do it, but you can 'cheat' to do this:

  

  You can move the table where the captions are, or even make the table turn into lines instead of the column.

  Is the idea ok for you?

• Set the name of a Visible plot and color lines draw graphic legend of XY

  Hi all

  Updated 20 plots data on that and I'm initializing the XY graph with 20 plots.

  After update of data, I do draw 3 to invisible, now I need to trace the legend to organize such that he should have, plot 0, plot1, plot2, plot4, plot 5... plot19, in the legend of his plot and should not have Plot3.

  So while graphic print and consult the chart in pdf format, I can see field only for Visible names draw in the legend of the plot and can avoid the confusion of having plot3 in my graphic impression. (Given that this parcel is invisible and data used pot in chart 3 and so I do not have this as my as well catalogue)

  Is there are ways of achieving them, please send your suggestions.

  Thank you

  Stéphane

  You can set the colors of the plot, point style, etc. by program like I did with the name of the parcel. The colors are just an extension of the notion that I have used with the array of names.

• How to remove a parcel and resize the legend of the plot in LV 8.6 as in this link to an example 7.0 LV

  This VI (ftp://ftp.ni.com/pub/devzone/epd/201150.vi) works exactly as I want to apply for a 8.6 at-, but the property node used in the example is no longer supported.

  I can add/remove sites and resize the legend of the plot with 8.6 using the 'LegNumRows' property, but this property does not behave in the same way.

  It seems like it should be simple, but I must be missing something.

  Thank you to confirm that this property does not work in the same way as in the example when it is used with a XY graph clusters and no dynamic data.

  I left the property node in the structure of the case (just as it was in the original example) while not to jam too when you went to compare two examples - my application does not for the reasons you stated.

  I will implement a legend Manager to ensure the follow-up of the plots in the legend.

  Thanks for the validation test!

• the plot legend disappear

  Dear friends,

  I'm using Labview 8.2.1

  Recently I came across a strange behavior of the XY graph. A few times the chart Plot legend Palette just disappear from the tab in which I use this chart. I enclose a picture of this.

  This seems to be a bug. Please suggest any fix.
