WPF CHART DATASOUCE CUSTOM STRUCT POINT

Graph DataSource in the Group ChartCollection

Graph.Plot = PointPlotRenderer

execution error:

Could not find item type conversion to type Double.

public struct item: IFormattable
{

Public item (double x, double y)

X = x;
Y = y;

public double Y {get; set ;}}

public string ToString (string format, IFormatProvider formatProvider)

Returns the string. Format ("{0}, {1}", X, Y);
}
}

To use a custom with the graphic data type, you must also implement a descriptor so that the graph knows how to access your data. I have attached a descriptor to another question, translated into c# for your type of data.

To use the descriptor, add a DataTypeDescriptor attribute to your custom type:

[DataTypeDescriptor( typeof( PointIDescriptor ) )]

    public struct PointI : IFormattable {

        // ...

  • "incomplete struct pointer" error

    I keep geeting error "Type error in argument 1 of 'DLLStruct '; "found"pointer struct parameters' expected ' struct pointer incomplete parameters "

    I'm trying to pass a pointer to a structure as an argument to a function in a DLL.  It's just a test code to see if it works, but it is pass the pointer struct to DLLStruct() and it is supposed to update a, b, c the values of 1,2,3).  Here is my code:

    void __stdcall DLLStruct (struct parameters * tester_params);

    struct parameters
    {
    int a;
    int b;
    int c;
    } tester_params;

    int main (int argc, char * argv [])
    {
    resultstr char [256];

    struct parameters * structPtr;
     
    structPtr = & tester_params;
     
    structPtr-> a = 0;
    structPtr-> b = 0;
    structPtr-> c = 0;
     
    DLLStruct (structPtr);
     
    sprintf (resultstr, 'a = %i ", structPtr-> one);
    MessagePopup ('test... (', resultstr);
     
    sprintf (resultstr, "b = %i", structPtr-> b);
    MessagePopup ('test... (', resultstr);
     
    sprintf (resultstr, 'c = %i ", structPtr-> c);
    MessagePopup ('test... (', resultstr);
     
    return 0;
    }

    Here's the DLL function:

    void __stdcall DLLStruct (struct parameters * tester_params)
    {
    tester_params-> a = 1;
    tester_params-> b = 2;
    tester_params-> c = 3;
    }

    If the code is written as stated in your post, this error depends on the fact that when you define your function DLLStruct structure is not yet defined. After the function declaration, you define the struct and use it when calling DLLStruct: right now you pass a structure completely defined for a function that expects an incomplete struct (which is not yet defined structure).

    Definition of the structure in motion before the function definition should eliminate the error.

  • 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.

  • Is it possible to update a chart "XY" whenever a point is generated as with a "table"?

    Is it possible to update a chart "XY" whenever a point is generated as with a "table"?

    In the attachment, the XY graph, 'OUT' is updated once the loop is completed. I would like to be updated as data is generated inside the loop. Is this possible?

    Thank you.

    To make it work, you need to do the full table available inside the loop.  This means that you cannot use a tunnel of indexing at the exit to build the array. Instead, you must use a shift register and build the table inside the loop.

    This will do what you want.  It would have been easier to show you if you had posted your code.

  • 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?

  • 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 - 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 ) {

            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 );

  • 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 */;

  • CS6 and custom curve Point as opposed to linear

    Then when I opened a new D700 shot in ACR with CS6 and go to the point curve Panel he customized the default value. That seems to have about 10-12 points on it and looks like it provides a slight lift in the shade and a slight decline in light tones. I can choose linear and I don't know how to save the new default, I'm just curious what the curve Custom is and whence it. I use the neutral profile V.4 If that makes a difference.

    I have not seen that this mentioned anywhere. Anyone he understand?

    What was once a curved point linear linear labled is now a curve of medium contrast labelled and designed to appear as a linear curve point.

    It is not a psychological problem. The fact is that there is now a hidden curve for linear curve point labled setting.

    Laughing out loud. It's more a psychological problem... the linear tone in the previous 2010 PV curve was NOT a real linear curve. It was still a modified gamma curve is same that adjustment was mild. If you set the PV 2010 tone to contrast and brightness linear curve and set, you'd come closer to a linear rendering but he had a non-linear gamma adjustment because she has been standardized for display and adjustments. Some people fell in love with the low contrast material, starting point. Some people also reserved to point curves and no base Panel setting. This is not an optimal approach now with PV 2012 because it ignores a lot of tone mapping the new base Panel can do.

    You can use DNG Profile Editor to edit a DNG profile for your camera and return to a more linear (not perfectly linear, only more linear) if that's what you want, but you can not do with any command in LR4/ACR7 now without getting the exposure settings and negative and several contrast curve of you pointson to set the new default curve is more linear (but still not exactly linear).

    As to why they converted the old medium contrast and defined now as a linear curve by default, which was to have no curve reference located in the default of the ACR/LR so that the curves could be applied to raw, tiff and even 32-bit images comma floating and use the default even starting point. The standardized medium contrast curve still lives in the DNG profile and this is where you change the middle to linear curve in a custom profile of DNG. Bottom line, the largest well is the mobile... some people do not like change, but they will not change because the people who don't like it are a tiny minority.
