• Select curve chart WPF and nickname of curve in the ToolTip

  Hello

  How can I do, view the name of curve in the ToolTip, if I moved the mouse over the curve?
  Or view the name of curve staring above the curve?
  And, how can I select a curve with the click of a mouse?
  Possible?

  Kind regards

  Using the logic of tool tip of the point value of graphic display WPF overviewand the GetPlotAt function, here's an example that uses mouse clicks to select tracks in a chart:

  partial class MainWindow: Window {}
  
  _selectedPlot of private land;
  public MainWindow () {}
  
          InitializeComponent ();
  Tour (option) on the hit test for lines, in addition to the actual data.
  
          Graph HitTestMode in the Group PlotHitTestMode.RenderedInterpolation;
  Updated tooltips to display quickly and for a long time.
  
          ToolTipService.SetInitialShowDelay (graph, 0);
  
          ToolTipService.SetShowDuration (graph, int. MaxValue);
  Fill in the chart with the data and the locations of the example.
  
          Graph BeginInit ().
  
          var plotBrushes = new [] {Brushes.Red, Brushes.Orange, Brushes.Green, Brushes.Blue ;}
  
          < plotbrushes.length;="" ++i="" )="">
  
              label As String = "Plot" + (i + 1);
  
              rendering engine of var = new LinePlotRenderer {Stroke = plotBrushes [i]};
  
              var field = new plot (label) {Renderer = renderer};
  
              Graph Plots.Add (field);
  Graph data [i] = new [] {i, i + 1};
  
          }
  
          Graph EndInit ().
  Monitor the plot area of the chart for mouse clicks.
  
          Graph. PlotAreaMouseLeftButtonDown += OnPlotAreaMouseLeftButtonDown;
  
      }
  private void OnPlotAreaMouseLeftButtonDown (object sender, MouseButtonEventArgs e) {}
  
          Check if a new route has been shown at the current position.
  
          Point ScreenPosition = e.GetPosition (graph);
  
          field var graphics = (Plot). GetPlotAt (screenPosition);
  
          If (plot == null | plot == _selectedPlot)
  
              return;
  Deselect the previous plot, if it exists.
  
          If (_selectedPlot! = null) {}
  
              ((LinePlotRenderer) _selectedPlot.Renderer). StrokeThickness = 1.0;
  
              (Graph (ToolTip). Tool - tip). IsOpen = false;
  
          }
  Select the new path and display a ToolTip.
  
          _selectedPlot = conspiracy;
  
          ((LinePlotRenderer) plot. Rendering engine). StrokeThickness = 2.0;
  
          Graph ToolTip = new ToolTip {Content = string. Format ('"{0}' selected', plot. Label), IsOpen = true};
  
      }
  
  }
  
  

  "Display the name of curve staring above the curve", with respect to the simplest approach would be to use a PointAnnotation to display a label to a particular position (probably hiding the target and arrow).

• WPF how to do? AxisCustomDivision grid, text?

  WINFORM:

  WPF:

  var d = CustomDivision (value)

  no text, no lines, no style grid?

• Format digital exponential WPF NumericTextBoxDouble FontSize and AxisDouble

  Hello!

  1.) how can I change the font size of NumericTextBoxDouble?

  I use this code:

  but the font size remains about 10-12 pixels.

  Why?

  2.) how can I disable digital scientific (exponential) format of the AxisDouble on the chart in WPF?

  Kind regards

  Tamas

  P.S.: I use VisualStudio community of 2013 and 2015 MS Standard

  (1) FontSize is the correct property. You have an implicit style for TextBox which is the substitution of the font size? For example, if I add " " for resources in a test window, which substitutes the font setting on the digital text box.

  (2) you can control the format of the labels division thanks to the LabelPresenter property on the MajorDivisions of the axis. For example, using " " will display the division labels using the fixed-point string of Format Standard Digital.

• AutoScale graphical wpf

  How can I autoscale graphical WPF on request? When you work with graphics WF, I used something like this (activate autoscale, then disable it):

  (Graph (AxisDouble). Axes [0]). Setting device = RangeAdjuster.FitLoosely;
  (Graph (AxisDouble). Axes [1]). Setting device = RangeAdjuster.FitLoosely;

  (Graph (AxisDouble). Axes [0]). Setting device = RangeAdjuster.None;
  (Graph (AxisDouble). Axes [1]). Setting device = RangeAdjuster.None;

  but chart WPF has no effect

  Immediately all the WPF Chart redraws the data when the Adjuster on a change in the axis. To do this manually, you can call the Refresh method on the chart. In your example:

  ((AxisDouble)graph.Axes[0]).Adjuster = RangeAdjuster.FitLoosely;

    ((AxisDouble)graph.Axes[1]).Adjuster = RangeAdjuster.FitLoosely;

    graph.Refresh();

    ((AxisDouble)graph.Axes[0]).Adjuster = RangeAdjuster.None;

    ((AxisDouble)graph.Axes[1]).Adjuster = RangeAdjuster.None;

• After a time when the data added to the interface user blocked - WPF

  I am currently using WPF graphics.

  I have created a simulation that describes the problem that I have experienced in my application (attached).

  I have two sons, we generate data (in my application gets the material data every second) and the other copies the data in the user interface (copy the data to a variable, which bind to the data source).

  Every second I get 1000 points and adds them to the data. The first seconds it works well, after a while it gets stuck.

  I added a listbox control that displays the time, need to add the variable data and gradually increases.

  

  I have two questions:
  (1) did whenever I have add data, it attracts all the existing data again? If so, theres a way to improve or prevent this behavior?
  (2) how many points can represent the graph at a glance? (which is the limit of the graph)?

  Thank you

  HODAYA Shalom.

  Your example updated debugging, I think that the question is the Dispatcher.Invoke calls that you use to communicate with the user interface thread. Since you use the delegate only, all calls are sent with Normal priority, which means that events of low priority (as made graphic, or updated on day of data binding to scales) can get transformed. Using a lower as priority Render four Invoke calls not glued to the UI in my tests.

• Chart WPF: AllPlots collection does not contain the scales in the second time.

  Hello

  I'm using WPF OR chart, and I'm in the binder through the datasource property.

  I have two axes in XAML that represent the scales.

  When you press the button I create random data (shown in the code below).

  But when I delete all data and adds the data in the list of places that have already been added in the past (for example: if I added 3 data in the past and now I'll add only 2 or 3), then plots that are created in the variable AllPlots not gets scales except the first (never erased) and he destroyed me certain things such as zooming.

  List newdata As new List();
  
  Random r = new Random();
  
  < 6000;="">
  
  {
  
     NewData. Add (r.Next (-20, 45));
  
  }
  
  Data.Add (newdata);

  Hmm, a very strange problem. Unfortunately, I can't reproduce this behavior at all: I still see '2' for each parcel, before clear or after.

  I guess that you have run the example as-is in a new project, without any other change to match your real application? And that you use the latest version of measurement Studio 2015?

• Chart WPF: How to get the limits of PlotArea and axes

  I can't find explicit methods to get limits of PlotArea and axes.

  Please let me know workarounds if they are available. Actually a post explains how to get the PlotArea limits using RangeCursor. Are there alternative means for shafts?

  The photo below shows what I did in WinForms with the methods GetBounds and HitTest. I would like to draw the ornaments on the chart in WPF.

  

  I have attached a code example of this look ornaments around the plot area and the scales.

  Note that this relies on implementation details of the current version of WPF controls for the ornaments of the scale, as it was more effective than gradually points to test in the graph using the GetScaleAt method. We have intentionally left much of the underlying primitive types with a minimum documentation, like us they have changed in the past and may change in the future. Although these exact members can be removed in a future release, we do not expect to provide an equivalent function and stabilize the primitive API over time.

• Chart WPF: How to add a space between the labels and tick marks

  I would like to know how to set a margin between the main graduations and their labels in a chart for WPF.

  Especially in the x-axis labels are placed very close ticks.

  

  Unfortunately, there are no existing configuration property to add an extra space around the scale labels. I created a task to address them in a future version of Measurement Studio.

  To work around the problem, you can use a string format that includes extra whitespace in the result:

  
  
          
  
              
  
                  
  
                      Format="{}{0} " />
  
                  
  
              
  
          
  
      

  If you need a check, you can create a custom label presenter to add extra space for the generated label visual.

• 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 );

            // ...

        }

• The point value of graphic display WPF overview

  Hello

  Y at - it an easy way to display the value of a point (with formatting similar to a slider) flying over when the mouse point? I use the chart control WPF (MStudio 2013) with several plots represented graphic on an AxisDouble. (y-axis) and AxisPrecisionDateTime (x axis). Let me know if you need more information and thanks in advance.

  When a Cursor is set to align the data, it uses the FindNearestValue method to find the value of land near. When it is not set to align the data, he reports the value of the current screen with the ScreenToData method. The following code example shows how to use both to display the current value of the mouse on a chart using a ToolTip:

  private static readonly GraphQueryArgs query = new GraphQueryArgs(

        PlotsToSearch.Any, SearchDimensions.HorizontalAndVertical,

        SearchDirections.ForwardAndReverse, isInclusive: true );

  public MainWindow( ) {

        InitializeComponent( );

  graph.PlotAreaMouseMove += this.OnPlotAreaMouseMove;

        graph.PlotAreaMouseLeave += delegate { graph.ToolTip = null; };

        ToolTipService.SetInitialShowDelay( graph, 0 );

        ToolTipService.SetShowDuration( graph, int.MaxValue );

    }

  private void OnPlotAreaMouseMove( object sender, MouseEventArgs e ) {

        IPlot plot = graph.AllPlots[0];

        Point screenPosition = graph.GetPlotAreaPosition( e );

        IList pixelValue = graph.ScreenToData( plot, screenPosition );

        string tip = string.Format(

            "Absolute value at point {0} is {1}.",

            screenPosition, FormatValue( pixelValue ) );

        Point relativePosition = graph.ScreenToRelative( screenPosition );

  PlotValue nearestValue = graph.FindNearestValue( plot, relativePosition, query );

        if( nearestValue != null )

            tip += Environment.NewLine + string.Format(

                "Nearest value on {0} is {1}.",

                nearestValue.PlotObserver.Label,

                FormatValue( nearestValue.Value ) );

  graph.ToolTip = tip;

    }

  private static string FormatValue( IList values ) {

        return string.Join( ", ", values.Cast

  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.

• Resize GraphInteractionPalette WPF

  Is it possible to resize a WPF GraphInteractionPalette to enlarge the icons? If so, how?

  There is no property to customize the size of the buttons on the palette of the interaction.

  To work around the problem, you can use the events Manager Loaded sample below to navigate through the visual tree and resize buttons. (Note that the buttons are currently using image resources for icons, which maybe isn't good in larger sizes).

  private void OnInteractionPaletteLoaded( object sender, RoutedEventArgs e ) {

        var palette = (GraphInteractionPalette)sender;

        ResizeButtons( palette );

    }

  private static void ResizeButtons( DependencyObject d ) {

        var button = d as ButtonBase;

        if( button != null ) {

            button.Width *= 2;

            button.Height *= 2;

        }

        else {

            int childCount = VisualTreeHelper.GetChildrenCount( d );

            for( int i = 0; i < childcount;="" ++i="">

                ResizeButtons( VisualTreeHelper.GetChild( d, i ) );

        }

• Graph: graph of WPF. Error Plots.Clear)

  Hello

  I need dynamically add patches to the chart. Code like this,

  ObservableCollection dataSource = new ObservableCollection ();

  Graph DataSource = dataSource;

  public void AddOnePlot (Point [] pointData)

  {

  Plot = new Plot();

  Graph Plots.Add (plot);

  dataSource.Add (pointData);

  }

  But when I call graph. Plots.Clear: the error is "beach action are not supported.". How to erase all the plots in the graph?

  Looking forward to your response. Thank you.

  The Plots collection on the Graph class derived from NotifyingCollection , which raises a single optimized global event when several items change. On the other hand raises the ObservableCollection .NET separate events for each item in the collection. Measurement Studio controls are supported on both models, but the WPF controls such as ItemsControl do not support aggregation events ("actions range" in the error message).

  However, there is a bug in the current version of the Legend control: If you bind the ItemsSource property to a collection rather than a chart, you may encounter this error if a default collection view is created. To avoid this, you can serialize events (as you demonstrated above, removing individual items instead of compensation), or you can use the NotifyCollectionChangedSimplifier to adapt the collection for the model "a separate event for each item:

  xmlns:ni="http://schemas.ni.com/controls/2009/xaml/presentation"

    xmlns:niPrimitives="http://schemas.ni.com/controls/2009/xaml/presentation/primitives"

• WPF graphics error: can't shoot outside a cycle of draw

  I get this error in my wpf with Measurement Studio 2013 application. After much headache, I realized this error only occurs if I add intrigue to the curve of this. Dispatcher.Invoke method of my background but work if I moved adding parcels to my main thread (RunWorkerCompleted code) I get this error again. I know that this error has been reported here before and this has been attributed to not having the most recent Measurement Studio library but I use the latest library. But I need to move this back to the background work because the addition of the plot in the main thread is blocking my UI. Thank you.

  I was able to reproduce the error with your project. The problem is with the implementation of the Auto mode able Studio 2013, where args made set caching using the old target were get called once the goal has been selected rendering.

  To avoid this, set RenderMode or Vector or Raster in the ulGraph.xaml file.
