Hi,

I have several chart panes that share a mouse group and a shared visual range (I inject the shared visual range of type IRange in the constructor of the pane view model). I then set the XAxis visual range to the shared visual range inside each pane view model. However, when I use either of the below approaches outside of the pane view model to adjust the min and max of shared visual range, the Xaxis.VisualRange of each pane does not reflect that change.

Approach A: _sharedVisualRange.Min = ….; _sharedVisualRange.Max = …
Approach B: _sharedVisualRange.SetMinMax(….)

Neither approach actually impacts the XAxis.VisualRange.Min/Max.

Initially when I created the XAxis in code I set its VisualRange equal to the shared visual range that was injected via constructor, like :

XAxis = new CategoryDateTimeAxis()
{
……
……
VisualRange = _sharedVisualRange,
…..
};

Please note that all the above refers to code in the view model. I bind the XAxis in the pane view model to the XAxis of the surface in xaml.

My entire synchronization heavily relies on the assumption of this working, but it does not.

Hi sir,

We would like to build a real time updated stackedcolumn chart in mvvm mode.
Is that possible? (x-axis on the left side)(y-axis on the bottom side which can keep update with only 10mins range)

I wonder can I use the StackedColumnRenderableSeriesForMvvm?
I found out this control but have no idea how to use it…

Hi SciChart team,

I have built a xyscatter chart with DateTime type X-Axis and Double type Y-Axis,
and built boxannotations to mark areas.

May I set the x-Axis value in the tooltip?
Or can I show properties of each item which means every point in the xyscatterseries, and customize the tooltip content style like adding the description of every properties.

Hello!

I am getting started with SciChart and attempting to use it for a project I’m working on.

I am attempting to make a 3D scatter plot whose data is populated through a ViewModel.

Below is a my xaml:

    </Grid>
</UserControl>

And below I declare and define my scatter plot in the viewmodel (the scatterSeries is an XyzDataSeries3D set somewhere else) :

    PositionalErrorTestModel.RenderSeries3DViewModels = new ObservableCollection<IRenderableSeries3DViewModel>();
PositionalErrorTestModel.RenderSeries3DViewModels.Add(new ScatterRenderableSeries3DViewModel
            {
                PointMarker = new SpherePointMarker3D { Fill = System.Windows.Media.Color.FromRgb(0x78, 0xC3, 0), Size = 5, Opacity = 1 },
                DataSeries = scatterSeries
            });

The chart appears, but the data does not. Is there something I’m missing? Do I need to explicitly call an update to the chart? Because the page the chart is on and the chart does get loaded before the data is populated.

Please let me know if you need to know anymore information.

Thanks for any help you can provide!

Hi,
I’m experimenting with the LegendModifier and want to control which RenderableSeries are shown via the “LegendItemTemplate” approach. The idea is to add a specific tagging class to the RenderableSeries.DataSeries.Tag and use the content inside the LegendItemTemplate which I define in the Window.Resouces.

The tagging Class:

public class DataSeriesTag
{
    public string LegendText { get; set; }
    public bool ShowLegend { get; set; }
}

The LegendItemTemplate:
<Window.Resources>

<Grid.ColumnDefinitions>

</Grid.ColumnDefinitions>

            <!--<CheckBox Width="16" Margin="5,0,0,0"
                HorizontalAlignment="Left"
                VerticalAlignment="Center"
                IsChecked="{Binding RenderableSeries.IsVisible, Mode=TwoWay}"
                Visibility="{Binding RenderableSeries.DataSeries.Tag.ShowLegend, Converter={dxmvvm:BooleanToVisibilityConverter}}" />-->

            <s:PointMarker Grid.Column="1" Margin="5,0,0,0" Width="40" Height="10" VerticalAlignment="Center" HorizontalAlignment="Center"
              DataContext="{Binding RenderableSeries}"
              DeferredContent="{Binding LegendMarkerTemplate}"
              Visibility="{Binding ShowSeriesMarkers, RelativeSource={RelativeSource AncestorType=s:SciChartLegend}, Converter={dxmvvm:BooleanToVisibilityConverter}}" />

            <TextBlock Margin="5,0,5,0"
     Grid.Column="2"
     HorizontalAlignment="Left"
     Text="{Binding RenderableSeries.DataSeries.Tag.LegendText}" />

        </Grid>
    </DataTemplate>
</Window.Resources>

As long as I declare the SciChartSurface.ChartModifier in XAML, it works perfect.
The proplem raises when I bind the ModifierGroup to a ViewModel Property and try to build the LegendModifier there. How can I assign the LegendItemTemplate in the ViewModel?:

legendModifier = new LegendModifier(){
            ShowLegend = true,
            ShowVisibilityCheckboxes = false,
            LegendItemTemplate = ??????
        };
        TheModifiers.ChildModifiers.Add(legendModifier);

Kind regards
Martin

We’re using ReactiveUI and bindings in code-behind. We’re now upgrading from SciChart v3 to v6 and we’re wondering how to use the SeriesBinding in code-behind like this:

public partial class BarChartView : ReactiveUserControl<sBarChartViewModel>
{
    public BarChartView()
    {
        InitializeComponent();

        this.WhenActivated(disposable =>
        {
            this.OneWayBind(ViewModel,
                            vm => vm.SeriesSource,
                            view => view.BarChart.SeriesSource)
                .DisposeWith(disposable);

            this.OneWayBind(ViewModel,
                            vm => vm.LabelProvider,
                            view => view.FaciesAxis.LabelProvider)
                .DisposeWith(disposable);

            this.OneWayBind(ViewModel,
                            vm => vm.TooltipDataContext,
                            view => view.TooltipModifier.TooltipLabelDataContextSelector)
                .DisposeWith(disposable);

            this.OneWayBind(ViewModel,
                            vm => vm.XAxisRange,
                            view => view.FaciesAxis.VisibleRange)
                .DisposeWith(disposable);
        });
    }
}

Now the IChartSeriesViewModel and SciChartSurface.SeriesSource is deprecated so we have to move to IRenderableSeriesViewModel instead and then bind to SciChartSurface.RenderableSeries. But how can we convert from IRenderableSeriesViewModel to IRenderableSeries here?

Hi
I’m trying to use AvaloniaUI with .NET Core 3.1 to create an application using SciChart, but I get XAMLIL error when trying to add a SciChartSurface following the code from the tutorial. I used a standard Avalonia MVVM Application template when creating the project.

This is the code:

<UserControl xmlns="https://github.com/avaloniaui"
             xmlns:s="http://schemas.abtsoftware.co.uk/scichart"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             mc:Ignorable="d" d:DesignWidth="800" d:DesignHeight="450"
             x:Class="FF_DataVis_Avalonia_MVVM.Views.TabControlView">

    <Grid>
        <!-- Bind to ChartViewModel.ChartTitle etc -->
        <s:SciChartSurface ChartTitle="{Binding ChartTitle}">
            <s:SciChartSurface.XAxis>
                <s:NumericAxis AxisTitle="{Binding XAxisTitle}"/>
            </s:SciChartSurface.XAxis>
            <s:SciChartSurface.YAxis>
                <s:NumericAxis AxisTitle="{Binding YAxisTitle}"/>
            </s:SciChartSurface.YAxis>
        </s:SciChartSurface>
    </Grid>
</UserControl>

And the error I get is:
“XAMLIL: Unable to resolve type SciChartSurface from namespace http://schemas.abtsoftware.co.uk/scichart Line 27, position 4″
which is the first s:SciChartSurface entry.

Any ideas what might be wrong? Does SciChart not work with any framework regardless of using .NET Core 3.0?
I have tried changing between Core 3.0 and 3.1, which does nothing.

Getting an exception when trying to add tooltip template MVVM style to a blox plot. The chart also contains a scatter plot which should not be styled. That works fine, hoverwer, when I move the mouse over a box in the box plot, the exception is thrown.

I want to keep the styling, I just want to write something different than the default text.

The template:

  <DataTemplate DataType="scalarPlot:ToolTipData" x:Key="BoxSeriesTooltipTemplate">
    <TextBlock>
      <Run Text="Max:      " />
      <Run Text="{Binding Maximum}" />
      <LineBreak />
      <Run Text="P90:       " />
      <Run Text="{Binding P90}" />
      <LineBreak />
      <Run Text="Median: " />
      <Run Text="{Binding Median}" />
      <LineBreak />
      <Run Text="P10:       " />
      <Run Text="{Binding P10}" />
      <LineBreak />
      <Run Text="Min:       " />
      <Run Text="{Binding Minimum}" />
      <LineBreak />
    </TextBlock>
  </DataTemplate>

The binding:

      <Style TargetType="s:BaseRenderableSeries" x:Key="BoxSeriesStyle">
        <Setter Property="s:TooltipModifier.TooltipTemplate" Value="{StaticResource BoxSeriesTooltipTemplate}"/>
        <Setter Property="s:TooltipModifier.IncludeSeries" Value="True"/>
      </Style>

The modifier:

<s:SciChartSurface.ChartModifier>
      <s:ModifierGroup>
        <s:TooltipModifier IsEnabled="True" ShowTooltipOn="Always" ReceiveHandledEvents="True" TooltipLabelDataContextSelector="{Binding ToolTipDataContext}"/>
      </s:ModifierGroup>
    </s:SciChartSurface.ChartModifier>

The view model:

    private static IRenderableSeriesViewModel CreateBoxPlotViewModel(BoxPlotDataSeries<int, float> boxPlotDataSeries)
    {
        return new BoxPlotRenderableSeriesViewModel
        {
            DataSeries = boxPlotDataSeries,
            Stroke = Colors.SteelBlue,
            Fill = new LinearGradientBrush(Colors.White, Colors.LightSteelBlue, new System.Windows.Point(0, 0), new System.Windows.Point(0.5, 1)),
            StyleKey = "BoxSeriesStyle"
        };
    }

The data context selector:

    public Func<SeriesInfo, object> ToolTipDataContext
    {
        get
        {
            return seriesInfo =>
                   {
                       return seriesInfo switch
                       {
                           BoxPlotSeriesInfo boxInfo =>
                               new ToolTipData
                               {
                                   Fill = seriesInfo.Fill,
                                   Stroke = seriesInfo.Stroke,
                                   Maximum = (float) boxInfo.MaximumValue,
                                   P90 = (float) boxInfo.UpperQuartileValue,
                                   Median = (float) boxInfo.MedianValue,
                                   P10 = (float) boxInfo.LowerQuartileValue,
                                   Minimum = (float) boxInfo.MinimumValue
                               },
                           _ => seriesInfo
                       };
                   };
        }
    }

Hi,

I am developing an MVVM WPF application and need to access the SelectedPointMarkers property of DataPointSelectionModifier from the ViewModel.

From looking at the DataPointSelectionModifier documentation (https://www.scichart.com/documentation/win/current/webframe.html#DataPoint%20Selection.html) I can see how you can get the X and Y coordinate values of a selected point in a view, by binding the PointMarkersSelectionModifier to a listbox.

However this doesn’t really help me, I need to get the coordinates of the SelectedPointMarker into a property inside the ViewModel that can be accessed, rather than just binding to a listbox in the view itself.

I’ve also looked at this similar post: (https://www.scichart.com/questions/wpf/i-want-to-bind-selectedpointmarkers-of-datapointselectionmodifier), but I had no luck getting Kenishis solution to work in my case.

How can i do this?

Thanks.

Hello,
I am trying to add a BoxAnnotation with MVVM pattern where the X-Axis is a DateTime axis. The annotation can be dragged into the X-direction. I need to know the DateTime of each position while dragging and also the final position(DateTime) of the BoxAnnotation when the drag Ended. I am listening to the DragDelta and DragEnded events in ViewModel. But here I couldn’t able to get the DateTime from X1 and X2 of that annotation model. I am sharing some snippets of my code. Can you please let me know how I can achieve this?

In xaml:

<Style x:Key="_boxAnnotationStyle" BasedOn="{StaticResource AnnotationBaseStyle}" TargetType="scichart:BoxAnnotation">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="scichart:BoxAnnotation">
                    <Border x:Name="PART_BoxAnnotationRoot"
              Margin="{TemplateBinding Margin}"
              Background="{TemplateBinding Background}"
              BorderBrush="{TemplateBinding BorderBrush}"
              BorderThickness="{TemplateBinding BorderThickness}"
              CornerRadius="{TemplateBinding CornerRadius}" />

Hello.
Thanks for previous answer but I can’t check how it work because of new problem. I develop WPF application and try to use MVVM as architecture pattern. In the Model part of my application I used a loop started in the new thread. In that loop I get some data which received to ViewModel and used as chart data. Looks as usual.
But then I tried to set visible range updated object which bound to axis I get exception ‘System.InvalidOperationException: ‘The calling thread cannot access this object because a different thread owns it.’ in my loop. I know it happens in WPF applications and need to use Dispatcher to solve it. But as I know if you try to use MVVM you not needed to use Dispatcher often because WPF-binding in most cases is thread-safe. That happend in my case? How to solve it?

Hi,
I’m prototyping an application with two visible data series and an individual Y-axis for each data series. See the enclosed image.
The Stroke color of each data series, the TickTextBrush and the BorderBrush of the y-axis are updated by normal data Binding through the MVVM pattern.
The problem is that I am not able to data bind the Stroke property of the MajorTickLineStyle for the individual Y-axis.
Do You know if there is a workaround for this through data binding?
The project is enclosed.
