Hi, I am currently working with the DataPointSelectionModifier with StackedColumnRenderableSeriesViewModel series. I currently am able to get the data point with the correct values whenever I click on a column but it seems that I am not able to change the selection fill of the column.

What I have tried right now is the following:

SelectionFill="{Binding Source={StaticResource GlyphColor}, Converter={StaticResource ColorToBrushConverter}}"

I have also tried setting the SelectionFill to a standard color.

But it does not update the color of the column on click. All I can seem able to do is changing the color of the whole series, but that is not what I am looking for.

Best Regards.

Hi ,

I am currently using the DataPointSelectionModifier for StackedColumnRenderableSeriesViewModel and I am having an issue trying to have a single selection that is togglable.  I am currently not AllowingMultiSelection so the default value is SelectionMode.Replace, which, in case you click on the same column, it will deselect that column and then select it again. Is there a way around this?

Best Regards.

Hi All
By default legends are being draw on scichart surface. I want to draw them outside the scichart surface because as the number of render-able series increase legends hides them. Please give me suggestion how do i do it ?

I want to know whether the FastRenderableSeries is out of VisibleRange or not. I can’t check with getIsVisible() as it could be invisible by the legend.

I have bound the annotation collection to the scichart as shown below.

Annotations="{s:AnnotationsBinding ChartAnnotations}"

And in the code behind (view model) i am adding annotations to the collection like,

   private AnnotationCollection _ChartAnnotations = new AnnotationCollection();
   public AnnotationCollection ChartAnnotations
      get { return _ChartAnnotations; }
         if (_ChartAnnotations == value)

         _ChartAnnotations = value;

   TextAnnotation annotation = new TextAnnotation();
   annotation.X1 = FirstX;
   annotation.Y1 = 2.0;
   annotation.Text = tempData1[(i - 1) >= 0 ? (i - 1) : 0].PacketType.ToString();

But I am not getting any annotation when I run it, moreover, the original scichart series is also getting disturbed.

Would be grateful if you look into the issue.

In my implementation I have the xAxis using a DateAxis in the dataset I am using there is only one data point.

The RolloverModifier is very sensitive it is very hard to highlight that one point.

RolloverModifier rolloverModifier = new VitalChartRolloverModifier();

Is there a way of making it less sensitive?

Hi I am implementing a chart on Android with 24 Hours of data viewable in 1, 2, 4, 8, 12 and 24 hours windows. The chart is drag-able upon the xAxis only. The full extent of the yAxis is always visible.

I am struggling to control the rate of scroll compared to the drag speed. What is desired is always a perceived one to one ratio of movement. This means that a data point’s movement distance when scrolled is the same is the point of touch’s movement distance regardless of zoom level.

I am currently using:

    ChartModifierCollection surfaceChartModifiers =  surface.getChartModifiers();
    XAxisDragModifier dragModifier = new XAxisDragModifier();

    ZoomPanModifier zoomPanModifier = new ZoomPanModifier();

Currently however the ratio does not appear to be one to one the scrolling move further than the touch drag distance.

How can I achieve this?

I am using the LegendModifier to bind my RenderableSeries to my legend.

In my legends Datatemplate, I have a checkbox and a colour picker.

I notice the LegendData object is of ChartDataObjectBase type. I would like to group my data in my legend (eg, with a label), rather than just display the list.

Is this possible, similar to the images attached ?

Thank you for your previous response however I would like to know how to recover the Date value from the AxisInfo parameter of the updateInternal method of the AxisToolTip class when used with a DateAxis.

To give context to the question. I am using a DateAxis for the xAxis on this chart and specifying a customised AxisInfoProvider as in the ‘CustomizationRolloverModifierTooltips’ example. When the RolloverModifier highlights some points and if ShowAxisLabels is true then the customised version of the updateInternal method of a customised AxisToolTip is called to to display the xAxis value on the axis.

The AxisInfo object contains a dataValue member variable the question then is: how to convert this back to a Date object.

I am moving from MPAndroidChart to SciChart but I am also required to provide the same look and feel on the chart produced.

In this app the line chart has three lineCollections vertically offset from each other in MPAndroidChart i could use the charts getHighLighter().getHightLight(x, y) to retrieve a list of the three HighLighted points. This information is then used to display detailed information on those points in a popup panel not part of the chart.

Further to this the highLighting only happens after a longClick where the HigHlight Lines and the popup info panel then appear. Chart scrolling is also disabled. The popup info panel is then updated with the point information as the highlight moves.

Upon touchUp the highlight and popup info disappear and chart scrolling is then enabled.

The RolloverModifier appears to provide the required highlighting but I am confused on how to get the points currently highlighted.

We use ViewportManager to automatically calculate the visible range of Y-axis for all series in the chart.

   <s:SciChartSurface Margin="0, 5, 0, 0"  Grid.Column="2"
                           ViewportManager="{Binding ViewportManager}"
                           MinHeight="250" MinWidth="250"
                           RenderableSeries="{s:SeriesBinding SeriesVms}"
                           ChartTitle="{Binding ChartModel.Title}"
                           YAxes="{Binding YAxes}"
                           XAxes="{Binding XAxes}"
                           Style="{StaticResource YAxisStyle}"
                           Annotations="{s:AnnotationsBinding ChartModel.Annotations}">
      : (omitted for brevity)

This approach works fine for one chart.

We now have an additional requirement, which is to have the same VisibleRange for Y-axis over multiple charts. Basically, the VisibleRange should be set to be the [Min, Max] range over all the series in all charts.

Is there a way to achieve this with ViewportManager ?
Is there a way to make several charts related and assign it a common instance of ViewportManager?

         <s:NumericAxis AxisTitle="Value"  VisibleRange="{Binding VisibleRange1}" Visibility="Collapsed"  DrawMajorBands="False" />

In ViewModel:

private static int r1 = 70;
private static int r2 = 50;

private IndexRange _visibleRange1 = new IndexRange(r2, r1);

public IndexRange VisibleRange1  => _visibleRange1;

I get the exception:
‘Axis type NumericAxis requires that VisibleRange is of type SciChart.Data.Model.IndexRange’

What am I doing wrong?

I’m working on a WPF app. Everything is OK except that I don’t understand how to render the series above the annotations.
The XAML code is the following:

<s:SciChartSurface Name="sciChartSurface"
                   Annotations="{Binding Path=Annotations}"
                   ChartTitle="{Binding Path=GraphTitle}"
                   DataContext="{Binding Path=ChartViewModel,
                   RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type charts:ChartView}}}"
                   SeriesSource="{Binding Path=Series}"
                   Padding="0 5 8 0">




    <!--  Create an X Axis  -->
        <s:NumericAxis AutoRange="{Binding Path=XAxis.AutoScaling,
                                           Converter={StaticResource BooleanToAutoRangeConverter}}"
                       AxisTitle="{Binding Path=XAxis.AxisTitle}"
                       DrawMajorGridLines="{Binding Path=XAxis.ShowGridLines}"
                       GrowBy="0, 0.1"
                       VisibleRange="{Binding Path=XAxis.AxisRange,
                       MajorDelta="{Binding XAxis.MajorDelta, Mode=TwoWay}"
                       MinorDelta="{Binding XAxis.MinorDelta, Mode=TwoWay}"
                       AutoTicks="{Binding XAxis.AutoTicks}" 

    <!--  Create a Y Axis  -->
        <s:NumericAxis AutoRange="{Binding Path=YAxis.AutoScaling,
                                           Converter={StaticResource BooleanToAutoRangeConverter}}"
                       AxisTitle="{Binding Path=YAxis.AxisTitle}"
                       DrawMajorGridLines="{Binding Path=YAxis.ShowGridLines}"
                       GrowBy="0.1, 0.1"
                       VisibleRange="{Binding Path=YAxis.AxisRange,
                       MajorDelta="{Binding YAxis.MajorDelta, Mode=TwoWay}"
                       MinorDelta="{Binding YAxis.MinorDelta, Mode=TwoWay}"
                       AutoTicks="{Binding YAxis.AutoTicks}"

Edit: this is the code that creates the horizontal annotation:

 /// <summary>
    /// Creates a chart annotation
    /// </summary>
    /// <param name="a"></param>
    /// <returns></returns>
    private AnnotationBase CreateChartAnnotation(Annotation a)
        HorizontalLineAnnotation annotation;

        //not used??
        //ColorToBrushConverter brushConverter = new ColorToBrushConverter();

        annotation = new HorizontalLineAnnotation() { Y1 = a.ThresholdValue.Value };
        annotation.Stroke = new SolidColorBrush((Color)ColorConverter.ConvertFromString(a.Stroke));
        annotation.HorizontalAlignment = System.Windows.HorizontalAlignment.Stretch;
        annotation.IsEditable = false;
        annotation.LabelTextFormatting = string.Format("{0} 0.0", a.Label);
        annotation.StrokeThickness = 2;
        annotation.LabelPlacement = LabelPlacement.Axis;
        annotation.ShowLabel = a.ShowLabel;
        if (a.DashArray != null)
            annotation.StrokeDashArray = new DoubleCollection(a.DashArray);

        return annotation;

I tried to set AnnotationCanvas.BelowChart but the behaviour is very strange: the horizontal annotation line is no more continuous
I attached two jpegs

Dear all,
I need to display an annotation label based on regional settings, especially grouping separator.

The annotation is define as below :

<s:HorizontalLineAnnotation x:Name="_threshold" HorizontalAlignment="Stretch"
                                        Y1="{Binding LiveThreshold,Mode=TwoWay}" 

If I check the row value LiveThreshold it is properly formatting according to regional setting and if we display it in another windows control through binding all is ok ans seen as 1,234 (“,” as grouping separator).

But when we apply that value to Y1 to the Annotation above, the result I get is a value which is not using the format of the value it self but overwrite it and for instance Grouping digit separator is completely ignore from regional seetings and display as : 1234

Q1 : Why the Annotation is not using the actually formatted string that I am delivering ?

I have try to add the LabelTextFormatting =”n” property. If I am in English Us in regional settings, then it display correctly then the Digit grouping as 1,234 .

But if I switch for instance to French in regional settings, then there is no digital grouping in French formatting so return data should be 1234. Instead I have an exception of “Input string is not a valid format” , which is wrong because the raw data value is correctly formed.

Q2 : Why adding the LabelTextFormatting =”n” crash in other language than US where digital grouping is different than “,” ?

Does anyone have met this case ?

Thanks for tips if any

Hello support team.

I have a question about the resampling modes and their behavior.
I have a LineRenderableSeries with the resampling mode.mid. Therefore, depending on the zoom level and available pixels of the display screen, the information of the min and max values are lost. I had the idea to create a second LineRenderableSeries with the Opacity 0.5 and the ResamplingMode.Min Max. Thus I have behind the main line with the resampling mode.mid a “cloud” with the MinMax info. This allows the user to see this information as well. However, I would deactivate this cloud if it is not necessary due to the zoom level and the pixels.
How can I request this from SciChartControl? Or does it make more sense to use a different functionality?
I use the Mvvm classes LineRenderableSeriesViewModel, and XyDataSeries.

Thank you very much!

I have a TabControl that contains a dynamic number of chart panes via an ItemsControl. Inside the ItemsControl’s ItemsTemplate is a single ScichartSurface with bindings to the RenderableSeries, XAxis, YAxes, and VerticalChartGroup.

The xaml looks something like this:

<s:SciChartSurface name="Chart" RenderableSeries="{Binding rSeries}" XAxis={Binding xAxis} YAxes={Binding yAxes} s:SciChartGroup.VerticalChartGroup="{Binding vGroup}">

Within the surface, I have a ModifierGroup that contains (in order) a RubberbandXyZoomModifier (XAxisOnly), MouseWheelZoomModifier, ZoomPanModifier, ZoomExtentsModifier, and a custom mod call TimeSegmentSelectionModifier. All of these modifiers have their ReceiveHandledEvents property set to True, they are all under the same MouseEventGroup, and they all seem to work fine under normal circumstances.

Note: The Rubberband and TimeSegment modifiers are inversely set to Enabled. Meaning, only one of them functions at a time.

My issue is primarily with the RubberBand Mod:

Let’s say I have 5 chart panes being displayed and I want to zoom in; If I click and drag within the 3rd chart, every chart zooms correctly.
If I click withing the 3rd chart, drag the mouse outside of that chart (anywhere else on my screen) and let go, then only charts 1, 2, and 3 are zoomed correctly. Charts 4 and 5 won’t budge and act as if I had merely zoomed to extents.

This happens with any number of chart panes and the issue occurs on whatever pane I happened to be zooming in on.

I’ve been troubleshooting this issue for a few days now and I don’t know where else to look.
Any help is greatly appreciated.

I created a custom annotation. In the custom annotation, I made a SciChartLegend and bind its Legend Data to LegendData of legendmodifier and also give the element name of it. But the problem I am facing is it is not updating the series info in the SciChartLegend when I am adding the series dynamically. But as I am using the VS 2017, I can change the code in xaml in runtime. So when I change the binding mode of legenddata like earlier it has Mode = OneWay, Now I delete the OneWay and type again the OneWay, now everything works fine. But on the first time, like on no change in the xaml , it is not updating the series info.

Here is my code for Legend Modifier :

 <s:LegendModifier x:Name="legendModifierTimeChart" ShowLegend="True" Orientation="Vertical" Margin="10"
                   LegendPlacement="Right" GetLegendDataFor="AllSeries" Focusable="True"
                   ShowVisibilityCheckboxes="True" ScrollViewer.VerticalScrollBarVisibility="Auto"
                   ScrollViewer.CanContentScroll="True" ShowSeriesMarkers="True"/>

Here is my code for Custom Annotation SciChartLegend:

<s:CustomAnnotation X1="0" Y1="0" CoordinateMode="Relative" IsEditable="True">
    <Border BorderThickness="3" BorderBrush="LightGray" Margin="10">
        <s:SciChartLegend x:Name="legendControl1"
            LegendData="{Binding LegendData.SeriesInfo, ElementName=legendModifierTimeChart, Mode=OneWay,UpdateSourceTrigger=PropertyChanged}"
            ShowVisibilityCheckboxes="True"   IsHitTestVisible="True"  />

It not works until I change the Mode on runtime, Like It already has written OneWay, but on runtime if I delete that and again write

OneWay, everything works fine.

Please help me in solving this issue. It is a humble request.

How to programmatically add Scrollbars to MVVM instantiated axes?

I added DateTimeAxisViewModel and NumericAxisViewModel to my code. That works from so far. A way to add scrollbars i couldnt find a some tries.

Are there some ways to get this done? Maybe change the templates of the axes or the chart?

Best regards

Hello support team,

We have to realize the following request:
– Yt chart with DateTime as X-axis and double values on the Y-axis
– The chart should display a user-defined area on startup (e.g. 20 sec) After the chart has run for 20 seconds ( i.e. 20 seconds), the animated scrolling should start. By default, the chart behaves as follows: The X-axis area fills up to 20 seconds and then starts scrolling. We want the chart to display 20 seconds on the X-axis at the start and fill up.

I am aware that I can implement this behavior myself. However, the question arises whether I can realize this directly with a basic functionality.

Thank you!

I’m trying to make a chart with a “toggle function”.

The “toggle function” what i wanted to make is this.

  1. enter to UIViewController which Chart is in it
  2. before singleTap on a chart, a chart has zoomPanModifier, XAxisDragModifier,, etc
  3. after make singleTap on the chart, that chart has only CursorModifier.
  4. CursorModifier’s UI stays on chart without disappearing and i can move crossed line to specific point i want (just like what CursorModifier originally does)
  5. another single tap on chart would make a chart to have all other modifiers but CursorModifer.

What I have made successfully was 1,2,3,5 . not 4.

The way i was going to solve this problem was make fake touch event on Chart view and
snatch UIGestureRecognizer Event and let ChartView think they’re being touched till I give stop signal

But I heard that there is no more way to pass fake touch to UIView.

So I’m feeling difficulty on this problem…..

is there any easy way to solve this problem?

Hello support team,

We are currently starting a complete redesign of our SciChart implementation from V3.x to V5.x. In V5.x the MVVM pattern is now supported and we would like to use this.
Our main focus is on the performance of the SciChart component. Now the question arises whether the use of the MVVM API is questionable for exactly this reason (performance).
Does it make a big difference whether I address the series directly or via the MVVM API?
Thank you very much for your support!

Hello support!
I have two questions, I would be very grateful for any information or hint.

  1. What methods can I use to bind a Visual Range to an Axis or Renderable Series to change them synchronously, I need to combine the series on 3 different surfaces.

  2. How can I control the YAxisDragModifier to block the movement of the Visual Range when a certain condition is reached. Thanks.

I have a DateTimeAxis.

While I can see a way to template the format the text for all the axis tick labels, I need a way to completely override what is being rendered for each item. I want, for example, today’s date to be in bold, and to apply other text/buttons below the axis label conditionally, depending on logic specific to that date.

Is this possible?

I am trying to update the value by doing:

But nothing happends…

I heard it was a bug in the API for Android a month ago, is this similar? Or am I doing something wrong?

I’ve enabled the Rollover on my chart, and I am trying to make a custom AxisLabelTemplate, which is easy to do if you are just looking to add some text/format around the AxisFormattedDataValue.

However, what i really want to do is to use the AxisInfo.DataValue to look up a specific string related to each of the Avis values, and set this as my label text;

ie, if my axis DataValues are “1, 2, 3, 4, 5″I want the rollover text to read “1 – Dog”, “2 – Cat”, “3 – Fish”, “4 – Mouse”, “5 – Aardvark”

Is this possible?

I’m writing regarding the IsCenterAxis property on the AxisBase object. I am creating biplots in my application and have set this property to true but the axes stay on the outside edge of the chart. Is there something else I must do to achieve this? I found a link in the forum about doing exactly this, but it was broken.

This is the broken link on the Navigation Pane page about “Placing Axis Central in the Chart”

Also, I need to draw a unit circle on my chart and I was curious what the best way to go about doing that would be.

Thank you

Hello, SciChart Team!
i have an issue using mouse drag event ( RubberBandXyZoomModifier, ZoomPanMidifier). the message says “NullReferenceException in SciChart.Charting.dll ” or “Thread.cs not found” from time to time.
after some experiments i figured out that the app starts to crush after i change XAxis type .
i have a simple mvvm user control used to display both arrays of double and datebound data, XAxes of SciChart Surfase is bound to an observable collection of IAxis elements. if i need to change chart type i clear this collection and create an axis of desired type (DateTimeAxisViewModel or NumericAxisViewModel). after that the series can be added, but zooming causes crash with nearly to no info.

i attached a solution, which lacks only scichart dlls in order to run (hopefully), Window_Loaded method has a commented line which changes chart type and makes app crush on zooming, would be nice if you checked it out.
Thanks in advance!

I’m trying to run my WPF with SciChart aplication in the separate AppDomain, but method SciChartSurface.SetRuntimeLicenseKey() is not working for me – no any exception, but in SciChart control I can see “Sorry! Your trial of SciChart has expired. Please contact sales if you require an extension.” instead of Chart.

In the default AppDomain it works fine.

I tried to run SetRuntimeLicenseKey method from both AppDomains – Default and separate, but without luck.

But I do not know how to use multiple colors at once.

can put multiple colors through Xaxes,
but when move the scroll bar, the Xaxes colors do not move together. (Top and Buttom Xaxes colors)
I want to move the colors of both Xaxes together. or want to assign multiple colors(over the 3 Colors) to one Xaxis.

You can see the code and graphs through the image.

Tell us how to use it.

I am currently taking a v5 test drive and noticed the following problem that would be a show stopper for me:

When syncing several chats via shared mouse events and shared visible x-Axis range I noticed that when zooming in that the chart axes get out of sync, sometimes significantly by several seconds on a CategoryDateTimeAxis, DateTimeAxis, but also apparently on numeric axes.

The error can easily be replicated when looking at your Example Suite , specifically the “Sync Multi Chart Mouse” sample. When you zoom into the chart you notice that the x-Axes on each chart are not aligned anymore. In this specific example when zooming in so that the minimum on the left side of the screen lies at around value 10 and the maximum at around 55 then moving with the mouse on the top chart to 52.44 shows a value of 52.53 on the lower chart. That is completely out of sync and gets worse on DateTime and Category DateTime axes.

Could anyone (and support) please chime in so I can understand what is going on and whether there is a fix for this or whether this is a bug that has been around for some time and cannot be adjusted within a reasonable amount of time?

I have been pulling my hairs over this and spent hours on different approaches, via ViewPortManager and the updating of shared visible range in both code and xaml. All to no avail and given the example code also exhibits the same issue I doubt it relates to a wrong implementation on my end.

Thanks a lot,
Matt W.

Greeting, I want to do a custom cursor, something just like the image, but with candles (a candlestick chart) , and I wanna see all the info (Date, open, close, high, low). Is there any example of it?

We are using SciChart in our Android application, and our Crashlytics reports that it crashes:

I developed a program using scichart.

Unfortunatly, It can not work on some computers.

There are same hardware and OS(Window 7).

I found this problem when I use DirectX.

I have referenced your code. and My code had ChangeRenderSurface method.

but It can not work well…

I think the problem occurred when I called scichart3d.

What is wrong?

Does it need to install anything else?

If you have a solution , please tell me.
