WPF chart: difficulty width of vertical axis

• Secondary axis on the WPF chart

  Hello

  I'm tracing a secondary value axis on my WPF chart. I have a graphic linked to a table of AnalogWaveform of objects that I change during execution. This table can be different sizes depending on the user's selection, however assume that there are two types of data to the chart.

  I would like to match a data type of my main axis and the other guy to my axis is secondary. For example, I have four AnalogWaveform opposes the plot, two of whom are in Hz (primary) and the other two in Volts (secondary).

  According to the documentation, I need an additional of element under my definition of . What I have is:

  This adds a second value axis to the left of my main axis. What I need is for this axis which will be located to the right of my chart and somehow to draw each AnalogWaveform on the right y-axis.

  I build my locations in the code as follows:

  
  
                  _graph. Plots.Clear ();
  
  
                  RawData is my AnalogWaveform[], built in advance based on a response from the server
  
                  foreach (AnalogWaveform waveform in RawData)
  
                  {
  
                      If (waveform! = null)
  
                      {
  
                          field = new plot (waveform. ChannelName);
  
                          parcel of land. DataContext = waveform;
  
  plots. Add (Plot); plots is a simple list
  
                      }
  
                  }
  
  _graph. Plots.AddRange (studs); Add locations to graph
  _legend. ItemsSource = plots. Add locations to the legend

  Any help would be appreciated on how to do it.

  Thanks in advance.

  To position your second Y axis across the graph, set the Location property on the axis of Far .

  To associate a plot to a default axis, set the VerticalScale property on the ground in the axis value is appropriate.

• Draw a line connecting two points in the WPF chart

  I'm trying to understand the best way to draw a line between two existing points on my graph in WPF.  At first, I thought I had it works fine; I just added another parcel to my graph then given exactly two points for rendering.  But I quickly noticed that the app has become surprisingly slow and CPU was quite high (adding other plots does not affect the use of the CPU as long as they have a complete set of points (?)).  He wants me if I looked at using the DataToScreen method on the chart but I can't know what the parameters are.  The second parameter is simply an IList that tells me a lot.  This seems to be the method I want to use for the coordinates of a point on the graph screen.

  No one knows what the second parameter is supposed to be for the DataToScreen method?  Everything I tried throws an Exception of Argument.

  Thank you
  Dan

  DataToScreenwill return a screen coordinate in the plot area of a chart of the value of the raw data horizontal and vertical in the given list. The parameter value is a IList for compatibility with other methods of graphical query such as FindNearestValue , return IList values containing raw data.

  A concrete example, say you had a graphical configuration with a wide horizontal axis ranging from 0 to 100 and a vertical axis double precision ranging from 10 to 20:

  
          
              
              
          
      

  To get the screen coordinates of the value at the center of the two axes, you can call:

  graph.DataToScreen(plot, new object[] { 50, 15.0 })

  Note that the raw data values corresponding to the type of axes (horizontal AxisInt32 returns the integer 50 and vertical AxisDouble Gets the value 15.0 ).

  You also mentioned a performance issue where "adding other plots does not affect the CPU so that they have a complete set of points". I did a simple test app that adds an array of two points of a chart on each key (for example graph.Data.Add(new[] { new Point(x1, y1), new Point(x2, y2) }); ), but could not reproduce the problem you saw. Could you share the code, you use to draw the connection line?

• How did you would return an ImageView along its vertical axis?

  Hello
  
  How did you would return an ImageView along its vertical axis? It would help me to reduce the number of image files, that I need in my project.
  
  Thank you
  Jose

  Apply a transformation of rotation of 180 degrees on its lower left corner followed by a translate directly by the width of the image.

  See http://jewelsea.wordpress.com/2011/11/16/rotation-transform-example/ for a code pointer (not exactly what you need but I hope it will help you understand how to achieve what you want).

• Tilt the image on the vertical axis?

  I don't want a complete vertical flipping. I just want to put an image on a green screen. How to fix the tilt?

  You will need to apply the 3D effect simple inclination to the vertical axis.

• Design of the Vertical axis labels

  Hi all
  
  I am a newbie to Flex and has difficulties with a BarChart, where the vertical axis labels are small enough to be almost unreadable. I would like to increase the EIS of the labels, while keeping the overall size constant.
  
  I've added an AxisRenderer to the vertical axis and specified a styleName with a fontSize 10. The effect has been to reduce the size of the labels even more! (In fact, the mere presence of the AxisRenderer without a specification styleName was sufficient to cause this additional reduction). Later, I defined a color in the style just to check that the style has been applied (if only partially).
  
  Is there a better approach for dimensioning of the axis labels? I'm using BF 3 Beta 3. Thanks in advance for your suggestions.

  A-ah! gutters!

• Hide the first and the last Division in the WPF chart axis

  I want to hide the default marker of the first and the last major division in an axis of a chart of WPF. I tried to extend RangeDivisionsMode and define my own class object to the MajorDivisions.Mode property on the axis. But even when I returns a list empty in RangeDivisionsMode.GetDivisions(...), the first and the last marker is drawn.

  Thanks in advance, Jonas

  The minimum and maximum labels are transmitted separately when displaying a scale (even if technical RangeDivisionsMode custom can be used for the minor divisions).

  There is no direct configuration option to hide extreme labels, but you can achieve this effect by initializing the LabelPresenter property on MajorDivisions by a custom implementation:

  class CustomFormatter : GeneralValueFormatter {

        protected override UIElement VisualizeCore( TData value, ValuePresenterArgs args, UIElement existingVisual ) {

            UIElement element = base.VisualizeCore( value, args, existingVisual );

  var axis = (Axis)args.Context;

            Range range = axis.Range;

            var comparer = range.Comparer;

            bool isExtreme =

                   comparer.Compare( range.Minimum, value ) == 0

                || comparer.Compare( range.Maximum, value ) == 0;

            element.Opacity = isExtreme ? 0.0 : 1.0;

  return element;

        }

    }

• WPF chart: formatting of the axis labels

  How to configure the chart to show only the first name label and the axis? I think that it is somehow needs to be done by changing the RangeLabeledDivisions.Mode property.

  You can set the Mode on the MajorDivisions to a page count mode two:

  
  
          Mode="Count: 2" TickVisibility="Hidden">

                ...
  
          
  
      

  This will show just the minimum and maximum divisions for the beach.

• Plots of non-visible WPF chart

  I am using measurement graphic studio in my WPF application. Firstly to my chart, the plots on it becomes sometimes invisible, but the graph becomes visible if I click on the limits of the axis or change the title of the axis. It happen with one is not specific in my request, and I'm not sure why it's happening. I will be grateful if someone could help with this.

  Thank you.

  
  

• WPF chart - select a horizontal range

  Hello

  I use the chart WPF of MS2015, I want to allow the selection of a range of horizontal (without zoom) so that the user can see the selected range.

  1. How do I allow to select the horizontal range in the chart?

  2. the data graphic is ChartCollectionAnalogWaveform , how can I access the data of the selected only (I want to show statistical data)?

  What you describe sounds like a perfect fit for the RangeCursor . For example:

  XAML
  
      
  
          
  
              
  
          
  
      

  Code
  
      foreach( IPlot plot in graph.AllPlots ) {

        var values = rangeCursor.RetrieveValues( plot );

        using( var xValues = values[0] )

        using( var yValues = (Buffer)values[1] ) {

            double average = yValues.Average( );

            string example = string.Format( "Plot {0} average over [{1:0}]: {2:0.##}", plot.Index, rangeCursor.ActualHorizontalRange, average );

            // ...

        }

• ObjectDisposedException with ChartCollection a WPF chart

  When I start the following program (WPF. net4.0, NI.common (13.0.40.190), OR.) Controls.Graph (13.0.40.242)) I get the following in the debugger error message

  ObjectDisposedException was not handled

  The data store has been modified.

  200ms - works ok, but hangs at the exception, when I change the size of the window

  20 ms - always ok

  I think that you run in the multi-threading problem described here: could not get Graph.DataSource to work in WPF, I (thread problem?).

  In short, your chart add calls must be marshaled to the user interface thread.

• Chart how many plots with wpf chart

  This is probably a very basic question, but I can't understand how the chart more than a set of data with the chart WPF in VS2010.  There is a DataSource property on the chart, but I don't see the same on each class of land.  I can't find any documentation on the source property of the chart data.  Can I pass an array of doubles and he plots very well but now I need to draw two sets of data.  Can anyone help?

  The DataSource property is documented in the how: map and graphic subject and on the GraphBase class (which is the type that defines the property). However, it seems that these issues do not directly address your question multiple plot; I put in a request to improve this.

  To answer your question, if you use DataSource to pass an array of double values in a plot, you can use a collection to pass data to multiple locations (for example a double[][] , a List , or a ObservableCollection ).

  Otherwise, you could use the Data collection to provide each parcel with data; for example:

  graph.Data[0] = /* double[] for plot 0 */;

    graph.Data[1] = /* double[] for plot 1 */;

• Label chart in the report generator axis

  Hello

  can someone help me with my problem?

  I need to add labels of the graph axis I've done by the Builder of Labview. Is it possible to do?

  I thank very you much.

  Patrik :-)

  I guess you make the graph in Excel.  The LabVIEW Report Generation Toolkit gives you a set of 'hooks' to make an Excel chart - it actually makes an 'object' that has a limited set of formatting options, but is quick and easy to use.  If you need a more detailed field, you're probably better write an Excel macro to generate the Excel data plot, then using LabVIEW for sae data to Excel, and then run this "macro tracing' to make the fantasy plot.

  However, here's how a conspiracy "simple."  The loop For generates data that are plotted (after transposing the data to give a picture of X and an array of Y) with graphic Insert, where I also put the title of the chart.  I then specify a label for the X ("category") and value axes, ('Value') with the result the plot shown below.

• Can build, but can not run a simple WPF chart

  Hello

  I just got my NI Measurnments Studio package and I try to add a graphic to my WPF c# application but I have questions that I have not seen in the examples of the trial.  Before you buy this package, I changed one of the examples of the trial to draw my own data and it worked beautifuly.  Now I tried to do the same thing in my own project and it builds without error but I get InitializeComponent() exception when I try to run it:

  "The call of the constructor on type"NationalInstruments.Controls.Graph"that matches the constraints of binding specified threw an exception."

• Horizontal menu with Vertical axis there too

  Hello
  
  I have a horizontal menu that works great except for two things:
  
  1. I want to scroll slowly when users have their cursor over or vertically beside her, but faster when they get it vertically or the cursor is on the object. So I think that if I use the FLF property that would work.
  
  2. the chart that scrolls horizontally Gets a little wonky at the place that is the 0 point (x and y) of the movieclip. As she slowly slips, it wobbles as it is slow to redraw.
  
  Below is the script of the object. Everything works except the if then statement with the FLF info and speed near the bottom. The menu is placed at x =-50 and y = 460 and it is 3155 pixels pixels x 102 wide maximum.
  
  Thank you!
  
  onClipEvent (load)
  {
  Overview = 400;
  Speed = 1/200;
  
  }
  onClipEvent (enterFrame)
  {
  var distance = overview - _root._xmouse;
  _x +=(distance*Speed);
  If (_x > 0) _x =-1550;
  If (_x <-1550) _x = 0;
  If the speed (FLF < 200) = 1/200;
  on the other
  Speed = 1/80;
  }

  your variable (speed) must change according to the FLF mouse property. but it is changing compared to the movieclip.

  I'm not sure that's what you want. You can use _root._ymouse.
