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.

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.

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 */;

Intensity chart non-visible grid

Hi all,

I can't get to show the grid on a graph of intensity lines. They show anywhere there is no data, but where there are data, they are hidden. Is this a bug or I do something wrong?

    griStats.Plot (stats)

    intensityPlot.PixelInterpolation = True
griStats.XAxes (0). MajorDivisions.GridLineStyle = UI. LineStyle.Solid

    griStats.XAxes (0). MajorDivisions.GridColor = Color.Black

    griStats.XAxes (0). MajorDivisions.Base = 0

    griStats.XAxes (0). MajorDivisions.Interval = 1

    griStats.XAxes (0). MajorDivisions.GridVisible = True

    griStats.XAxes (0). Range is new user interface. Range (0, UBound (twa))
griStats.YAxes (0). MajorDivisions.GridLineStyle = UI. LineStyle.Solid

    griStats.YAxes (0). MajorDivisions.GridColor = Color.Black

    griStats.YAxes (0). MajorDivisions.Base = 0

    griStats.YAxes (0). MajorDivisions.Interval = 1

    griStats.YAxes (0). Range is new user interface. Range (0, UBound (tws))

    griStats.YAxes (0). MajorDivisions.GridVisible = True

Thanks for your help,

Hey there,

Try this. Hook on the IntensityGraph.AfterDrawPlot event.

private void intensityGraph1_AfterDrawPlot (object sender, NationalInstruments.UI.AfterDrawIntensityPlotEventArgs e)
{
    intensityGraph1.DrawGridLines (new NationalInstruments.UI.ComponentDrawArgs (e.Graphics, e.Bounds));
}

I hope this helps.

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 );

            // ...

        }

    }

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?

Non-visible text of contacts in Outlook

Hello
I suffer from the same issue that I found posted anywhere on the internet this morning - my Contacts list is illegible because the text is barely visible, as if the map is too small for the space allowed.

I have:
My cache of dumping
Played with the zoom and CTRL - sets all the text to view, but at this time, it is too small to read.
Checked the section tools/options/content - minimum size fonts the value 'none', web sites set their own sizes.
All my browsers / add ons etc are up to date
It looks fine in IE, but I don't use IE

What else is there?

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 exception occurs in the DLL, so I can not catch it either.

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.

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;

        }

    }

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."

That's what I have:
- Added to my project references (VS 2013)
C:\Program Files (x 86) \National Instruments\MeasurementStudioVS2012\DotNET\Assemblies\Current\NationalInstruments.Common.dll

C:\Program Files (x 86) \National Instruments\MeasurementStudioVS2012\DotNET\Assemblies\Current\NationalInstruments.Controls.dll

C:\Program Files (x 86) \National Instruments\MeasurementStudioVS2012\DotNET\Assemblies\Current\NationalInstruments.Controls.Graphs.dll
- Added to this, notably in XAML
"" xmlns: or = 'http://schemas.ni.com/controls/2009/xaml/presentation '
- And added this chart control to XAML
<>area of Label = "Channel 1" x: Name = "Plot1" / >
<>area of Label = "Channel 2" x: Name = "Plot2" / >

Nothing else behind it, so I should at least power run and see a graph empty, right?

Please advice.

Thank you!

I got it work. Basically, it was licening known issue in 2013 VS. I had the .licx added manually in my project file. Here is the email that I received or who has been very useful:

"I noticed that you use Visual Studio with Measurement Studio 2013 2013. Currently measure Studio 2013 is only officially supported by Visual Studio 2012, however, many of our clients were able to make it work with Visual Studio 2013 Measurement Studio 2013. We have an article for the knowledge base that walks by working with Measurement Studio 2013 in Visual Studio 2013. It might be good to make sure you followed every step through this article: http://digital.ni.com/public.nsf/allkb/C51E3B38578FAD2786257C070069F386

It looks like you are using the correct assemblies, and we were able to test the XAML for our side. It works beautifully, so it doesn't seem like there's something is happening with the code. Another thing, we can try is to clean the Solution and regenerate the Solution in Measurement Studio. It will be a good step to make sure that no old persistent files. »

White on white page PDF non-visible objects

I created a white object in InDesign, I need to provide for the printing of T-shirt. When exporting to PDF the white object is not visible on the white background of the PDF.
Is there a way to show the limits of the object you can see them in InDesign not in preview mode?
Another solution would be to non-printable background, which is easy to create in InDesign, but converts it to white when you export to PDF or if you choose to display nonprinting areas, converts it to print again.
Any help

Or select the transparency grid in the Acrobat preferences.

Non-visible graphical displays
Hello

In analytics (OBIEE 11g) when I create a new graphical analysis views are not displayed. The table view works and shows all the data correctly, but when I want to add a new view, then click on what either graphic (such as a vertical bar graph or a pie chart) I get a window with a red in the corner as if it isn't loading. When I create a pdf report of this, graphical displays are still visible.

Anyone know what is the problem and how can I fix this so that OBIEE shows me charts too?
