Using custom label provider I am able to format the cursor label, but still there is the name of the axis. I only want to show the value here, like “0,91” and remove the “X:” (see attached screenshots).

Thanks in advance.

override func formatCursorLabel(_ dataValue: SCIGenericType) -> String! {
    return "" // super.formatCursorLabel(dataValue)
}

I’m getting a Argument Exception with the message: An item with the same key has already been added.
This happens when I use the Rollover or Cursor Chart Modifiers.
Visual Studio is unable to evaluate the exception.

Hi !
Is it possible to display the RollOverModifier tooltip on the real points only ? Say I have points (1 1) and (3 3) in my chart and I don’t wan’t the tooltip to display (1.5 1.5), (2 2), (2.5 2.5) etc. when rolling over… Any idea ?

Thank you,

Adrien

Hello !

I have a chart displaying very accurate data and I would like the RolloverModifier to adopt the same format as my Y axis.
I want to avoid problems similar to the one on the screenshot attached. The tooltip is indicating -0 and I would like it to display something like -2.5E-6.

Thank you for your help,

Adrien

In the Knowledge Base, an article discusses a rollover modifier that utilises a vertical hit test to draw a vertical line at the cursor and highlight the nearest point: http://support.scichart.com/index.php?/Knowledgebase/Article/View/17235/32/custom-chartmodifiers—part-1—creating-a-custom-rollover-modifier

This is perfect for data which moves/is unique along the X axis (such as time series data).

How can I best replicate this modifier for data which moves/is unique along the Y axis? Drawing a horizontal line is easy, but there is no HorizontalSliceHitTest function.

Hi,

I’m trying to update a chart from version 3.1.x of a chart. In the old chart there was a XyScatterRenderableSeries with markers width set to 8. The Rollover line had the same width as the marker and it was easy to hit a point. After update the rollover line is thin and it is hard to hit a point. Please advise if it is possible to get back the old behavior.

I want to have Y axis starting at 0 at the bottom and max value at the top, but I also want 0 index in heatmap data buffer to be displayed at the max value. I was able to achieve that using your HeatMapExampleView by modifying CreateSeries method like this

return new Heatmap2DArrayDataSeries<int, int, double>(data, ix => ix, iy => h - iy);

Note the iy => h – iy. What I noticed is that after doing that the RolloverModifier stopped working. How can I fix this or is this a bug?

After migrating to 4.0.5, I have shadows on my tooltips as below.
Also, the herringbone pattern is new to 4.0.
I have:

  </Border>
</ControlTemplate>


<s:SciChartSurface.ChartModifier>
    <s:ModifierGroup>
      <s:RolloverModifier s:Name="rolloverModifier"
                                    LineOverlayStyle="{StaticResource RolloverLineStyle}"
                                    DrawVerticalLine="True"
                                    SourceMode="AllSeries"
                                    ShowTooltipOn="MouseLeftButtonDown"                                  
                                    ShowAxisLabels="True" />
      <s:SeriesSelectionModifier ReceiveHandledEvents="True" />
    </s:ModifierGroup>
  </s:SciChartSurface.ChartModifier>

Any hints on how to get rid of them?

Could I get some help on this please?

Why I can’t access to the TooltipContainerStyle property in RolloverModifier in SciChart v4.0?
I’ve read documentation and it seems that it should work but it doesn’t ;(
Does it any other way to change the tooltip label in RolloverModifier?

Dear All:

I have been looking for a good way to obtain data from a multi-line chart (more than 1 y-value/y-axis) by either clicking an area that’s highlighted with a vertical line rollover, or selected with a vertical slice.

Basically I would like to take the data that I see in the Series Vertical Slices example, and extract the X-Axis values, as well as the Curve A, Curve B, and Curve C values that are shown on the vertical slice, so that I can insert that in something like a TextBox in a WPF.

Any idea how to do this, as well as with MVVM? (Will use MVC if necessary).

Thanks kindly!

Hi,

I am displaying some charts on the screen (4 per screen). When I double click one chart, it opens in another, modal window.
I have the below problem with the tooltip modifier and the rollover modifier (one is enabled at a time, tried with both, need the fix at least for the tooltip modifier)

When I close the window, the following happens, to the chart that was double clicked:

1- If the chart is a simple column chart, the tooltip modifier does not work as soon as the maximized window is closed. Nothing happens when I move the mouse. I found a simple workaround, which is to zoom in/out even very little, and the modifier works back. Here I’m forcing it by code:

private void ChrtSurface_OnMouseDoubleClick(object sender, MouseButtonEventArgs e)
        {
            //Get the chart from the sender tag
            var surface = (SciChartSurface)sender;
            var chart = (SciChart)surface.Tag;

            //The chart is already executed, so no need  do that again. Start the single view form
            var form = new SingleChartView(new SingleChartViewModel(chart, this._viewModel.SelectedModule.Id));
            form.ShowDialog();

            ZoomChartToExtents(chart);
        }

public void ZoomChartToExtents(SciChart chart)
        {
            var scichartSurface = lstCharts.FindVisualChildren<SciChartSurface>().FirstOrDefault(x => x.Tag == chart);
            Dispatcher.CurrentDispatcher.BeginInvoke(DispatcherPriority.ApplicationIdle, new Action<SciChartSurface>(ZoomExtents), scichartSurface);

        }

        public void ZoomExtents(SciChartSurface chart)
        {
            chart.ZoomExtents();
            chart.ChartModifier.OnModifierMouseUp(new ModifierMouseArgs() { MouseButtons = MouseButtons.Right });
        }

2- If the chart is a stacked chart, I get a null reference exception. Here’s the exception:

“An exception of type ‘System.NullReferenceException’ occurred in Abt.Controls.SciChart.Wpf.dll but was not handled in user code

Additional information: Object reference not set to an instance of an object.”

And the stack trace (if zoom extents is not called):

More info in case it helps:

I tried using the SimpleRolloverModifier code from http://support.scichart.com/index.php?/Knowledgebase/Article/View/17235/32/custom-chartmodifiers—part-1—creating-a-custom-rollover-modifier

And found that when the problem happens, the hit test either detects nothing or causes a null reference.

The problem ONLY happens when I open and close the modal window. If I don’t do that all works fine.

Thanks

Hi,

NOTE: Still using Scichart 1.7 here…

I have two questions about the rollovermodifier behaviour:

  1. As you can see in the picture, when rolling over the chart, sometimes the Xvalues of the series are not aligned. Is it possible to force this to be the same? Basically i always want the Xvalue to be the same for all the series when rolling over, would be nice to have the xvalue where the vertical bar is shown…
    Two hitpoints

  2. Might be just the chart behaviour, but is it possible to have the rollover feedback performed for values not in the visible range? When zoomed in, and for instance the top of the columnBar is not within the range, the seriesinfo is not shown for this datapoint.

Thanks a lot for the feedback.

Hello,

I would like to use the RolloverModifier to display a given datapoint’s identification (string) metadata. The solution suggested in this link on correlating metadata to datapoints seems promising, but for the fact that I have multiple charts to display simultaneously, hence I need multiple lookup arrays. I originally thought to use a ValueConverter that would manage lookup of the identification value based a chart view model instance code (ChartId) and the index provided in the XyzDataSeries. As control charts are instantiated, they register with the ValueConverter, which maintains a static lookup dictionary. In the XAML, the ZValue is passed as the value and the chartID is passed as a parameter to the ValueConverter. I have run into a couple key challenges, however:

  1. ConverterParameters cannot be bound; hence I cannot bind to the ChartId, whether it is stored in a viewmodel or in a different XAML element.
  2. WPF does not allow use of nested value converters in XAML; this prevents me from nesting the ValueConverter within the chart view model (where reference to the ChartId is readily available).

I’m exploring some other options, but they are getting ugly fast, so I figured it’s time to ask for assistance. Is there another way to do this (desirably adhering to MVVM practices)?

Key excerpts of my code are pasted below:

Surface:

<TextBlock x:Name="ChartIdBlock" IsEnabled="False" Text="{Binding ChartId}"/>
<s:SciChartSurface x:Name="ScsControlChart" MinHeight="200" s:ThemeManager.Theme="BlackSteel">
<s:SciChartSurface.RenderableSeries>
    <s:FastLineRenderableSeries x:Name="Data" SeriesColor="White" DataSeries="{Binding Chart, Converter={StaticResource ChartDataToDataSeriesConverter}}" IsSelected="True"/>
   <!-- More data series in same chart -->
</s:SciChartSurface.RenderableSeries>
<s:SciChartSurface.XAxis>
    <s:DateTimeAxis  VisibleRange="{Binding XRange, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" TickLabelStyle="{StaticResource AxisLabelStyle}" />
</s:SciChartSurface.XAxis>
<s:SciChartSurface.YAxis>
    <s:NumericAxis DrawMajorBands="True" VisibleRange="{Binding YRange, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" TickLabelStyle="{StaticResource AxisLabelStyle}"/>
</s:SciChartSurface.YAxis>
<s:SciChartSurface.ChartModifier>
    <s:ModifierGroup>
        <s:RolloverModifier x:Name="RolloverModifier" DrawVerticalLine="True" SourceMode="SelectedSeries" TooltipLabelTemplate="{StaticResource RolloverLabelTemplate}"/>
    </s:ModifierGroup>
</s:SciChartSurface.ChartModifier>

RolloverLabelTemplate:

<ControlTemplate x:Key="RolloverLabelTemplate" TargetType="s:TemplatableControl">
    <Border Grid.Row="1" HorizontalAlignment="Left" VerticalAlignment="Top" Background="#77FFFFFF" BorderBrush="#55000000" BorderThickness="1" Padding="5">
        <ItemsControl ItemsSource="{Binding ElementName=RolloverModifier, Path=SeriesData.SeriesInfo}">
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                        <StackPanel Grid.Column="2" Orientation="Horizontal" Margin="3,3,20,3">
                            <TextBlock FontSize="13" FontWeight="Bold" Foreground="{Binding SeriesColor, Converter={StaticResource ColorToBrushConverter}}"
                                       Text="{Binding ZValue, Converter={StaticResource IndexToIdConverter}, ConverterParameter={Binding ElementName=ChartIdBlock, Path=Text}}"/>
                        </StackPanel>
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ItemsControl>
    </Border>

Value Converter:

public sealed class ChartIndexToIdConverter : IValueConverter
{
    private readonly static Dictionary<int, Tuple<int, string[]>> _lookup = new Dictionary<int, Tuple<int, string[]>>();
    private readonly static Random _rnd = new Random();

    public static int Register(IControlChart chart)
    {
        var key = _rnd.Next();
        while (_lookup.ContainsKey(key)) key = _rnd.Next();
        _lookup.Add(key, new Tuple<int, string[]>(chart.First().Index, chart.Select(d => d.Id).ToArray()));
        return key;
    }

    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        if (value == null) throw new ArgumentNullException("value");
        if (parameter == null) throw new ArgumentNullException("parameter");
        var tuple = _lookup[(int)parameter];
        return tuple.Item2[(int)value - tuple.Item1];
    }

A question was recently asked on priority support tickets – how to to apply a Template Selector to the RolloverModifier, to display different tooltips based on series type?

We are answering the question below so that other users can benefit from it!

Hi All,
Although this issue isn’t currently stopping me doing what I need to do I’m just a tad worried that I’m doing something more fundamental wrong which probably will. Anyway the question…

I have a chart with a DateTime axis to which I add two series (red and blue points) from the code behind as per the code snippet. When I run it both series are displayed correctly but the rollover bar only snaps to the second series points. If a run the mouse over a point from the first series it seems to be acknowledged as the fill colour changes but the rollover doesn’t snap to it.

The method is invoked by a button press on a parent control

public void AddTestDataSeries(double seedvalue)
{ 
    DateTime StartPoint = DateTime.Now;
    DateTime[] Axis = new DateTime[] { StartPoint.AddMinutes(1), StartPoint.AddMinutes(2), StartPoint.AddMinutes(3), StartPoint.AddMinutes(4), StartPoint.AddMinutes(5), StartPoint.AddMinutes(6), StartPoint.AddMinutes(7), StartPoint.AddMinutes(8) };
    double[] Series1 = new double[]{1,2,3,5,7,12,19,37};
    double[] Series2 = new double[]{10,20,30,40,50,60,70,80};

    XyDataSeries<DateTime, double> dataSeries1 = new XyDataSeries<DateTime, double> { SeriesName = "Series1" };
    for (int x = 0; x < Series1.Count(); x++)
    {
        dataSeries1.Append(Axis[x], Series1[x]);
    }
    XyScatterRenderableSeries scatterRenderSeries1 = new XyScatterRenderableSeries();
    scatterRenderSeries1.DataSeries = dataSeries1;
    scatterRenderSeries1.PointMarker = new EllipsePointMarker()
    {
        Fill = Colors.Red,
        Stroke = Colors.White,
        StrokeThickness = 2,
        Width = 10,
        Height = 10,
    };
    this.UserControlSciChartSurface.RenderableSeries.Add(scatterRenderSeries1);

    XyDataSeries<DateTime, double> dataSeries2 = new XyDataSeries<DateTime, double> { SeriesName = "Series2" };
    for (int x = 0; x < Series2.Count(); x++)
    {
        dataSeries2.Append(Axis[x].AddSeconds(30), Series2[x]);
    }
    XyScatterRenderableSeries scatterRenderSeries2 = new XyScatterRenderableSeries();
    scatterRenderSeries2.DataSeries = dataSeries2;
    scatterRenderSeries2.PointMarker = new EllipsePointMarker()
    {
        Fill = Colors.Blue,
        Stroke = Colors.White,
        StrokeThickness = 2,
        Width = 10,
        Height = 10,
    };
    this.UserControlSciChartSurface.RenderableSeries.Add(scatterRenderSeries2);

}

And the XAML is simply

<UserControl
         x:Class="SummaryDrillDownCharting.SummaryDataChartUserControl"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

         xmlns:s="http://schemas.abtsoftware.co.uk/scichart"  
         mc:Ignorable="d" 
         d:DesignHeight="300" d:DesignWidth="300">

<Grid>
    <s:SciChartSurface x:Name="UserControlSciChartSurface" s:ThemeManager.Theme="Chrome">

        <s:SciChartSurface.XAxis>
            <s:DateTimeAxis GrowBy="0.1, 0.1"/>                
        </s:SciChartSurface.XAxis>

        <s:SciChartSurface.YAxis>
            <s:NumericAxis GrowBy="0.1, 0.1" DrawMajorBands="True"/>
        </s:SciChartSurface.YAxis>

        <s:SciChartSurface.ChartModifier>
            <s:ModifierGroup>
                <s:RolloverModifier IsEnabled="True"></s:RolloverModifier>
            </s:ModifierGroup>
        </s:SciChartSurface.ChartModifier>

    </s:SciChartSurface>
</Grid>

ADDITIONAL INFO: I Just ran the same code changing the scatter to a FastLineRenderableSeries – same problem exists.

Hello,

Is there an event that is triggered by the rollover modifier, or some other modifier for that matter?
Basically, I am trying to get the X/Y values of the point that the mouse is currently over through code.

Any help is appreciated.

Hello,

I am currently using a rollover modifier to display tooltip values on the trend. Whenever a data point is clicked however, the trend stretches so this point is along the right hand axis, and it pans so this point is along the x-axis. Is there a way to disable this feature?

Here are my modifier declarations:

<SciChart:SciChartSurface.ChartModifier>
            <SciChart:ModifierGroup>
                <SciChart:RubberBandXyZoomModifier  IsXAxisOnly="False"/>
                <SciChart:XAxisDragModifier/>
                <SciChart:CursorModifier ShowAxisLabels="False"/>
                <SciChart:RolloverModifier ReceiveHandledEvents="False" ShowTooltipOn="Always" ShowAxisLabels="True" UseInterpolation="True" SnapsToDevicePixels="False" TooltipLabelTemplate="{StaticResource RolloverLabelTemplate}"/>
            </SciChart:ModifierGroup>
        </SciChart:SciChartSurface.ChartModifier>

Thanks,
Andrew

Hi,

I’m using the rollover modifer on some charts. I’m using an XYDataSeries<int, int>. However, the tooltip is displaying the Y values as decimal with 3 floating precision (screenshot attached), while what I want is a simple integer to show. Here’s the chart code in xaml:

<s:SciChartSurface FlowDirection="LeftToRight" s:ThemeManager.Theme="Chrome" SeriesSource="{Binding Series}" ChartTitle="{Binding Title}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Name="chrtSurface" MouseDoubleClick="ChrtSurface_OnMouseDoubleClick" Tag="{Binding}">

                                    </s:NumericAxis>
                                </s:SciChartSurface.XAxis>

                                <s:SciChartSurface.YAxis>
                                    <s:NumericAxis GrowBy="0,1" AxisTitle ="{Binding YAxisLabel}">

                                </s:SciChartSurface.YAxis>

How to do that? Let’s use the SciTrader as the example. We have CandlestickRenderableSeries, Ma500, Ma200 series on the chart. In rollover mode, I only want the CandlestickRenderableSeries show its tooltip. Please help.

Many thanks!

Hi

I’m having trouble making the RolloverModifier TooltipLabels stay inside the graphs canvas.

screenshot

As you can see on the left most graph the colored sqaures and some of the digits has fallen outside the graphs canvas.
Also what are the TooltipLabels rules for clustering together, and rules for which side of the RolloverMarker the labels should appear on?

Still having a problem here… After setting the ClipModifierSurface on the SciChartSurface to False the time axis no longer clips the TooltipLabels.
But the graph itself clips the TooltipLabels when the label gets to large.

How do I make the labels stay inside the graph? As there is a lot of free space to the right of the labels.
