After updating to SciChart 3.1, I started getting the following binding error:

System.Windows.Data Error: 4 : Cannot find source for binding with reference ‘RelativeSource FindAncestor, AncestorType=’Abt.Controls.SciChart.Visuals.SciChartSurfaceBase’, AncestorLevel=’1”. BindingExpression:Path=MaxFrameRate; DataItem=null; target element is ‘HighSpeedRenderSurface’ (Name=”); target property is ‘MaxFramerate’ (type ‘Nullable`1’)

I’m not binding MaxFrameRate anywhere nor do I have a HighSpeedRenderSurface explicitly defined in my code, so I’m guessing this error is occurring somewhere in a SciChart control.

I have several SciChartSurface elements across different controls in my application. I tried setting a global style:

<Style TargetType="{x:Type s:SciChartSurfaceBase}">
    <Setter Property="MaxFrameRate" Value="24"/>
</Style>

This had no effect on the binding error.

Any help would be appreciated since I think these errors are affecting the loading speed of my UI.

Hi support. I currently evaluating SciChart and using FastOhlcRenderableSeries with CategoryDateTimeAxis to display stock chart intraday data. As you know, when I display many days of 1 minute intraday data (9h30 to 16h00) it is confusing to distinguish trading days since the XAxis is only showing time:sec format. I want to achieve to add tickmarks or any vertical lines to separate the first data for each day. How could I do that?
Thanks for your help.

If i do this:

  public void createTestGraph()
    {
        var series = new FastLineRenderableSeries()
        {
            SeriesColor = Colors.Red,
            DataSeries = GetDataSeries()
        };

        var xAxes = new AxisCollection()
        {
            new NumericAxis()
        };

        var yAxes = new AxisCollection()
        {
        new NumericAxis()
        };

        var surface = new SciChartSurface()
        {
            ChartTitle = "Rendered In Memory",
            XAxes = xAxes,
            YAxes = yAxes,
            RenderableSeries = new ObservableCollection<IRenderableSeries>() { series },
            Annotations = new AnnotationCollection()
        {
            new BoxAnnotation()
            {
                X1 = 10,
                X2 = 30,
                Y1 = 10,
                Y2 = 40,
                Background = new SolidColorBrush(Colors.Green),
            },

            new VerticalLineAnnotation()
              {
                X1 = 35,
                Stroke = new SolidColorBrush(Colors.Yellow),
                StrokeThickness = 3,
                ShowLabel = true,
                LabelPlacement = LabelPlacement.Axis
              }
            }
        };

        ThemeManager.SetTheme(surface, "Chrome");
        surface.Width = 1000;
        surface.Height = 1000;

        // Export to bitmap
        var bitmapSource = surface.ExportToBitmapSource();
        GraphTools.SaveBitmapToFile(bitmapSource, "D:\\TestChart.png");
        bitmapSource = surface.ExportToBitmapSource();
        GraphTools.SaveBitmapToFile(bitmapSource, "D:\\TestChart2.png");

I get the following:

In TestChart.png everything is as expected,
in TestChar2.png the BoxAnnotation is missing…

The effect of missing BoxAnnotations occors also in other not so clearly defined circumstances which gives me major headaches when trying to produce graphs for reports… Is there a bug oder an oversight of my part ?

(Using Old Version 3.1.0.4549)

Afternoon gurus, I’m currently playing around with the various modifiers that’re available and I’ve noticed something odd keeps happening. When I modify the axes of a series with the drag modifier DragMode.Scale, the ZoomExtents modifier for that series stops working. DragMode.Pan doesn’t produce the same issue, it zooms just fine. Is this a known issue or am I creating it with my code? For clarification, the drag modifier starts with IsEnabled = False and ZoomExtents works just fine.

I am using SciChart for WPF version 1.3.1.1107 with the MVVM pattern.

I have several lines in one chart where the data from for each line covers the same date time range. I’d like to be able to move a line to the front so that I can better see its data. Currently the order in which I add the lines seems to impact the zindex of the lines series.

Is this possible?

Hi Guys,

I have successfully added text labels to my charts using ILabelProvider.

However, some of the charts are showing duplicate labels for each bar, and others are not showing the labels for all bars (even though there is space to do so).

Any idea how to fix these? See the attached images for more details.

Thanks in advance.
Andre.

Hi,

By default I get a slight gradient on all chart surfaces(see attached image). Is there any way to get rid of it?

Thanks & Regards!

Hi,
Is there solution to always display series name below the line on the chart, not in legen, but I need to hide legend and I do not know what is series name. Thank You

Hi,

In our application there are several different Chart types. We want to add a slider (similarly in the screenshot) for each chart to zoom it. Have you got any example at all for this purpose or what is the recommended way to do this?

Thanks,

Best Regards,
Charith

Hello.
Using SciChart v2.2.
BaseRenderableSeries.HitTest(MousePoint) triggers not only in series pane, but also in other panes.

My hit-test code is below, called from public override void OnModifierMouseMove(ModifierMouseArgs mouseEventArgs)

foreach (var renderSeries in ParentSurface.RenderableSeries)
            {
                var series = renderSeries as BaseRenderableSeries;
                bool isCandleSeries = ((series as FastCandlestickRenderableSeries) != null);

                if (series != null && series.DataSeries != null)
                {
                    var hitTest = series.HitTest(mouseEventArgs.MousePoint);

                    if (hitTest.DataSeriesType == DataSeriesType.Ohlc)
                    {
                        seriesAnnotaion[k].X1 = hitTest.DataSeriesIndex;
                        seriesAnnotaion[k].Y1 = hitTest.CloseValue;

                        if (hitTest.IsHit)
                        {
                            //show tooltip
                        }
                     }
                  }
               }

I have a SciChartSurface with several FastLineRenderableSeries. I may have several days worth of per second data in each series. I have set my XVisibleRange to 10 minutes and I update it every second to make sure the view stays current. I want to also allow the user to either pan or zoom that view but only on the x axis. I see the demo of the SciStockChart using the IsPanEnabled that allows the functionality I want but that does not appear to be available on the SciChartSurface. Is there another way to accomplish this or do I need a different type of chart?

 private void VerticalLineAnnotation_PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)
    {
        if (e.PropertyName.Equals("PositionChanged"))
        {
            // Code here
        }
    }

I am trying to get the new Y1 intercept. I have bound this to both the VerticalLineAnnotations (y1 and y2 on those elements are NaN and null respectively) and to the VerticalSliceModifier which seems to give me the old values, instead of the new ones. I currently have this attached to the property changed event.

Essentially, the datacontext is staying the same but the collection is updating with new values. When it updates with new values, I need to update my LineAnnotation with the new Y1 and Y2 values.

Thanks!

Hi Guys,

I am creating and placing my custom annotation on my chart and its all fine.

Just a simple question :

When the annotation is created and placed I can see its anchor point which disappears (hide) when I select (click) on the chart surface.

Is there a way (programmatically) to “unselect” the custom annotation just after it has been placed in order the anchor points disappear ?

Thanks to you all

Kind Regards

Giuseppe

Hello,

it would be fantastic to be able to select the series visualized in the overview control. If i understood correctly, it’s always the first serie that is shown currently.

I added a screenshot, where 2 overviews are used. Both are based on the same first series (Curve 1). To be able to select another curve for overview 2 would be awesome.

Thank’s a lot!

Regards,
Robin

hi,
I have a vertical annotation and I want to restrict the scrolling of annotation between an x axis range.

ie, When I drag and reach left most point, it should not move beyond that point. Same should happen when I reach right most point.

How can I do that?

Hi!

I was wondering if there is any way to make the Y-axis wrap around?

We are using SciChart in a maritime application that handles the heading of a ship. The heading goes from 0 degrees to 360 degrees (or rather back to 0 degrees). When using a normal Y-axis from 0 to 360 a fluctuating value around 0 degrees (0 degrees +- 0.5 degrees for instance) will draw a line all over the chart’s Y-range, but in real life this is really a small change with little amplitude. A correct representation would be to put 359 degrees at the position of -1 degrees. But if we use negative angles we would still get the problem of large amplitudes at some point in our range (for instance using a range from -180 to 180 would lead to problems when fluctuating around 180).

Hello.

Found a bug: when working with the axis-X scales the Y-axis
To get started, you need to configure in SciChart so zooming and moving only happened on the axis-X

Next:

1. Take any chart (1.png)
2. Highly scalable any point (2.png)
3. Try to move the schedule of shifts sharply to the side, Y-axis scale changes (3.png)
4. increase the scale to its original condition(4.png)

At the same time if you do everything except the third paragraph then all is well

This is a bug or need to configure something else?

Hi Guys,

Can you please help me with the following functionality?
I have got a context menu attached to the SciChartSurface and one of the items is to add an annotation(as it is shown in the image attached). So, the idea is that when I open the menu and select the “Add annotation” It will pick up the nearest point in the chart related to where the click was done and then it will add the annotation to the chart as it is shown in the image attached.
I have already figured out with reading some of the question in this forum, to get the mouse points and the nearest Y point in the series related to that mouse click… like this:

private void AddAnnotationOnClick(object sender, RoutedEventArgs e)
{
// Hit tests are done per renderable series, so get a renderable series
// or iterate over all RenderableSeries
var renderableSeries = SciChartSurface.RenderableSeries[0];

        // Perform the hit test relative to the GridLinesPanel
        var hitTest = renderableSeries.HitTest(MousePoint);

        SciChartSurface.Annotations.Add(new CustomAnnotation { DataContext = hitTest.YValue });
    }


    private Point MousePoint { get; set; }

    private void OnMouseUp(object sender, MouseButtonEventArgs e)
    {
        MousePoint = e.GetPosition(SciChartSurface.GridLinesPanel as UIElement);
    }

As it can be noticed, I have already two annotations that are fix, they are always displayed…

Sorry for my terrible English… hope you guys get the idea…

Thanks very much. 🙂

I am trying to implement the DigitalFastLine Series from the example given in ‘http://support.scichart.com/index.php?/Knowledgebase/Article/View/17224/37/how-to-make-line-series-draw-to-the-right-edge-of-the-chart’

public class LinesEnumerable : IEnumerable<Point>
{
    protected readonly IPointSeries _pointSeries;
    protected readonly ICoordinateCalculator<double> _xCoordinateCalculator;
    protected readonly ICoordinateCalculator<double> _yCoordinateCalculator;
    protected readonly bool _isDigitalLine;

    public LinesEnumerable(IPointSeries pointSeries, ICoordinateCalculator<double> xCoordinateCalculator, ICoordinateCalculator<double> yCoordinateCalculator, bool isDigitalLine)
    {
        _pointSeries = pointSeries;
        _xCoordinateCalculator = xCoordinateCalculator;
        _yCoordinateCalculator = yCoordinateCalculator;
        _isDigitalLine = isDigitalLine;
    }

    /// <summary>

    public virtual IEnumerator<Point> GetEnumerator()
    {
        return _isDigitalLine ?
            (IEnumerator<Point>)new DigitalLinesIterator(_pointSeries, _xCoordinateCalculator, _yCoordinateCalculator) :
            new LinesIterator(_pointSeries, _xCoordinateCalculator, _yCoordinateCalculator);
    }

    /// </returns>
    IEnumerator IEnumerable.GetEnumerator()
    {
        return GetEnumerator();
    }
}

However, when I try to do the following:

linesEnumerable = linesEnumerable.Concat(new[] { new Point(viewportWidth, lastYCoordinate) });

it says ‘System.Collections.IEnumerable’ does not contain a definition for ‘Concat’ and the best extension method overload ‘System.Linq.Queryable.Concat(System.Linq.IQueryable, System.Collections.Generic.IEnumerable)’ has some invalid arguments

I already have System.Linq and Collections namespace added

What’s going on here? Can you improve your sample?

Hi,

I am hoping that someone can help me with the following issue…
I am implementing a Multiple Charts binding where the itemsControl is binding to the RolloverData.SeriesInfo (Like the example of the rollover feedback) so I display a little panel at the top of the diagram displaying the x and y values.
unfortunately, when the mouse moves over a chart it shows the values but then if I move to the next chart it shows the X and Y values in both charts and what I want to happen is that when the mouse moves to the another chart the previous chart don’t display the panel with the values.
I am attaching a picture of what happens thanks:)

Hello again

Now, im trying to make AnnotationCreationModifier without xaml, but i cant find any event like ‘AnnotationCreated’ and couldnt find any topics/tutorials how to create it without using xaml

I have a MouseWheelZoomModifier. It works fine when I first run my app but if I click a control outside of the chart (in this case a control on a Telerik RibbonBar) the mouse wheel zoom stops working. All other legends continue to work ok (RubberBand, ZoomPan, ZoomExtents).

Any idea what the problem could be? This is my code:

var zm = MouseWheelZoomModifier();
zm.IsEnabled = true;
zm.ActionType = ActionType.Zoom;

Hi,

I have a chart which has its YAxes and Series bound to a view Model. When I try to add an axis in real time I get an “InvalidOperationException” –
“Could not draw an annotation of type Abt.Controls.SciChart.Visuals.Annotations.AxisMarkerAnnotation. YAxis with Id == DefaultAxisId doesn’t exist. Please ensure that the YAxisId property is set to a valid value.”

I believe this might be because I don’t have an axis set up at start. Here are my Chart Modifiers <s:SciChartSurface.ChartModifier>
<s:ModifierGroup >
<s:SeriesValueModifier/>
<s:AnnotationCreationModifier x:Name="annotationCreation" AnnotationCreated="OnAnnotationCreated" YAxisId="Y1"/>
<s:XAxisDragModifier ClipModeX="None" />
<s:YAxisDragModifier IsEnabled="True" ReceiveHandledEvents="True" AxisId="Y1"/></s:ModifierGroup>
</s:SciChartSurface.ChartModifier>

Can you tell me what I need to do to avoid this exception. Also, I don’t see the Series Values Modifier working, I’m sure its related to this problem.

Please let me know,
Thanks,
Deepak

Hi

We have a requirement of creating a Time line chart similar to Gantt Chart,
Now we have created the same by increasing the thickness of Line chart,
But the main problem we are facing is line end cap, Currently it is rounded shape we could’t find a solution to make it flat.
We tried customrendarables series also but faced lot of issues while zooming and panning.

My question is whether you include following functionalities in the coming versions
1. Provide Gantt charts ?
2. Provide an API to change like end cap to flat ?

Hi!

I am trying to use SciChartGroupPane and ChildPanes for my application, and
want to collapse a pane , so that the remaining space is filled with the remaining graphs.

I tried to set the visibility to collapsed but, when i do that the panes only disappear,
but the remaining pane does not resize.

As I see the panes have two small buttons on the upper right corner for collapse and close,
This collapse button is similar to what i would want but I have no idea how to reach the collapse
functionality throgh code. Is it possible to collapse a pane withouth removing it from the container
for the ItemTemplate?

Thanks
Chris
