See the Attached image — On the right side in addition to the labels 0.01% – 20.0%; Their is a color coded chart of AAA through C/D.

I need this to also be part of the chart; or maybe a separate control that can be transformed and zoomed based on where the chart is at.

If I’m zoomed in on the 0.15% – 0.50% then the B/BB/BBB should also be zoomed in to match the current scale of the chart.

Ideas on how to handle this. I’ve tagged this question as Android, but I will also need a solution for iOS.

This is what I want it to look like: (see 1.jpg)

This is what (see 2.jpg) it does look like if I leave setIsLabelCullingEnabled enabled (all labels are culled except if I zoom WAY in)
This is what (see 3.jpg) it does look like if I turn off setIsLabelCullingEnabled

I would expect #2 to look like #3 without either one of the 20/15% and either 1% or 1.25% culled, when culling is enabled.

First things the specific values/locations are precise, I need those lines and labels exactly where they are. So I had to create my own LogarithmicNumericTickProvider and feed it all the numbers; this worked great and the numbers are where they need to be — but apparently using our own LogarithmicNumericTickProvider totally breaks culling. Any ideas on how we can get culling to work with our own LogarithmicNumericTickProvider. Is their another way to do this without using our own LogarithmicNumericTickProvider.

I think offline environment is problem. so can you guide how to install on offline pc?

Hi,

I have a usercontrol which has SCI chart controls. This usercontrol is added and removed from a parent Window based on few business logic.
While adding the control i get the following error.

Error: Element already has a logical parent. It must be detached from the old parent before it is attached to a new one.

In one of the forum it was mentioned that this was a known issue and was rectified. Please let me know on a workaround to overcome this issue.

Thanks,
Deepak

To whom this may concern:

I am following up to an issue that I posted a few years ago: https://www.scichart.com/questions/wpf/resizing-custom-annotations

I’ve attached a sample project that outlines what I am trying to accomplish. It is a simple scatter chart with randomized points in which I am trying to draw a rotatable ellipse annotation around the points.

The annotation inherits the “BoxAnnotation” class and replaces it’s template with an ellipse that is shaped to within the bounds of the annotation. This ellipse can be rotated by dragging the ellipse with the right-click button of the mouse. Upon doing so, in order to ensure the ellipse still maintains its shape when zooming in, the ellipse is converted to a geometric path. (Shown when the color of the ellipse changes from red to green.) Like this, when re-sizing the ellipse, it maintains its shape. After re-sizing, if the user wants to rotate the ellipse again, the original Ellipse UIElement re-surfaces and the Path UIElement is hidden. The user can then rotate the ellipse, which is in turn rendered back to a Path UIElement once again. The bounds of the annotation are modified to ensure the ellipse and its geometric path maintains its shape when switching between the Ellipse and the Path UIElements.

The issue is when re-sizing the annotation, and then attempting to rotate the ellipse again, the ellipse is clipped by the bounds of the annotation, even though “ClipToBounds” is set to false (in the code-behind). Unfortunately, I can’t find a pattern for which this occurs, and I have no solution to this issue. Examples of the clipped and non-clipped ellipses are shown in the attached images.

Hopefully the attached project is easy to understand. Can you please advise?

Thank you kindly!

I’m updating from Xamarin iOS SciChart v2 to v3 and just hit the issue that i can not use a custom TickProvider because there is no overridable UpdateTicks method.

I could not find any TickProvider code in the v3 Examples so the docs are my only source:
https://www.scichart.com/documentation/ios/current/axis-ticks—tickprovider-and-deltacalculator-api.html

According to the docs, I should override SCINumericTickProvider or SCIDateTickProvider

class CustomNumericTickProvider: SCINumericTickProvider
{
    public override void UpdateTicks(SCIDoubleValues minorTicks, SCIDoubleValues majorTicks)
    {
       //...
    }
}

But there is no UpdateTicks method to override.
I tried to override the Update() method instead:

public override void Update()
{
    Ticks.Clear();

    Ticks.MajorTicks.Add(5);
    //...
}

But that is just causing a freeze/crash at runtime.

It’s worth noting that it works well on Android because there is a UpdateTicks method to override.

What should I do?

Hello,

I am trying to add series to a linechart, however I seem to be unable to create a XyDataSeries in Kotlin I have tried the following:

private val linedata = XyDataSeries<Double, Double>().apply { fifoCapacity = FIFO_CAPACITY } 

// like from the ECG showcase example, this gives the error 
// "none of the functions can be called with the arguments called"

private val linedata2 : IXyDataSeries<Double, Double> =  XyDataSeries(Double.class, Double.class)

private var linedata3 : XyDataSeries<Double, Double> = XyDataSeries(Integer.class, Double.class).build()

This seems quite straightforward but I am unable to find a solution. Can you help me?

Kind regards,
Bart

I have a chart with many data series, each with their own Y-Axis. Initially i set the data series to hidden to stop the chart being filled with all the Y-Axes but when the data series is selected from the legend i want to show the Y-Axis for that data series and hide again when deselected.

What i would also like to do is limit the number of data series visible at one time, is this possible?

I’m able to turn the SciChartOverview control so that it appears vertical and am able to get the grips to flow vertically as well but whenever the data is flowing, it still flows horizontally. How do I get it to flow vertically? See attached image for what it currently does.

Few questions. First on a normal scichartsurface you have option to turn debuging to the console on. I do not see that option for the donut surface. Is there another way? Also if you have donutsegmentviewmodels and all values are 0 it throws an exception in the application. Is this expected behavior? I’d think the default behavior would just be to not render?

We currently have up to 4 charts that are stacked vertically and the data flows horizontally. However, we need to reverse it so that they are stacked horizontally and the data flows vertically. We currently have a grid setup for the charts to be set to but I can’t seem to figure out how to reset the Grid.Row and Grid.Column of each SciChartSurface at runtime.

Example:
Horizontally, this is how it looks…

<s:SciChartSurface x:Name="sciChartSurface1" Grid.Row="0" Grid.Column="1">

Vertically, it needs to be this…

<s:SciChartSurface x:Name="sciChartSurface1" Grid.Row="1" Grid.Column="0">

Is this possible to do at runtime/from the backend code?

Two questions. First how do I draw an axis label for every column in a column chart. See attached pic. Also the first axis label is correctly positioned under the column chart but subsequent ones are off to the left quite a bit. Not sure how to fix either. Here is xaml to rotate the axis lablel

<Style x:Key="SessionBreakDownByHourColumnGraphXAxisLabelStyle" TargetType="sc:DefaultTickLabel">
    <Setter Property="LayoutTransform">
        <Setter.Value>
            <RotateTransform Angle="45" />
        </Setter.Value>
    </Setter>
</Style>

UPDATE: Setting autoticks to false shows all axis labels but still off center. Adding new photo.
UPDATE: So changing xaml to below and adding a few to visible range on xaxis seems to solve the issue. Still unsure why i have to modify the visible range slightly.

<Style x:Key="SessionBreakDownByHourColumnGraphXAxisLabelStyle" TargetType="sc:DefaultTickLabel">
    <Setter Property="LayoutTransform">
        <Setter.Value>
            <RotateTransform Angle="45"/>
        </Setter.Value>
    </Setter>
    <Setter Property="HorizontalAnchorPoint" Value="Left"/>
    <Setter Property="VerticalAnchorPoint" Value="Bottom"/>
</Style>

Final Xaml that solved for me

<Style x:Key="SessionBreakDownByHourColumnGraphXAxisLabelStyle" TargetType="sc:DefaultTickLabel">
    <Setter Property="LayoutTransform">
        <Setter.Value>
            <RotateTransform Angle="45"/>
        </Setter.Value>
    </Setter>
    <Setter Property="HorizontalAnchorPoint" Value="Left"/>
    <Setter Property="VerticalAnchorPoint" Value="Bottom"/>
    <Setter Property="FontSize" Value="9"/>
    <Setter Property="FontWeight" Value="Bold"/>
    <Setter Property="Margin" Value="-5,0,0,0"></Setter>
    <Setter Property="Foreground" Value="{DynamicResource AccentBaseColorBrush}"/>
</Style>

When the GrowBy property on NumericAxis3D is specified, a tooltip modifier on the same 3D chart shows over data points that are not those under the mouse pointer.

To replicate the issue:

  1. Clone the examples project from GitHub and open the SciChart2D3D.Examples solution.

  2. In UniformColumn3D.xaml change the XAxis, YAxis, ZAxis and ChartModifier elements to the following, from line 101 onwards:

    <s3D:SciChart3DSurface.XAxis>
        <s3D:NumericAxis3D AutoRange="Always"  />
    </s3D:SciChart3DSurface.XAxis>
    
    <s3D:SciChart3DSurface.YAxis>
        <s3D:NumericAxis3D AutoRange="Always" />
    </s3D:SciChart3DSurface.YAxis>
    
    <s3D:SciChart3DSurface.ZAxis>
        <s3D:NumericAxis3D AutoRange="Always" />
    </s3D:SciChart3DSurface.ZAxis>
    
    <s3D:SciChart3DSurface.ChartModifier>
        <s3D:TooltipModifier3D HoverDelay="150" CrosshairMode="Lines" ShowTooltipOn="MouseOver" />
    </s3D:SciChart3DSurface.ChartModifier>
    
  3. Run the application and observe that the 3D Charts -> Basic Chart Types -> Uniform Column 3D chart shows a chart with correct tooltips appearing when the mouse is hovered over columns on the chart.

  4. Add GrowBy=”0.1, 0.1″ to each axis property as follows:

    <s3D:SciChart3DSurface.XAxis>
        <s3D:NumericAxis3D AutoRange="Always" GrowBy="0.1,0.1"  />
    </s3D:SciChart3DSurface.XAxis>
    
    <s3D:SciChart3DSurface.YAxis>
        <s3D:NumericAxis3D AutoRange="Always" GrowBy="0.1,0.1" />
    </s3D:SciChart3DSurface.YAxis>
    
    <s3D:SciChart3DSurface.ZAxis>
        <s3D:NumericAxis3D AutoRange="Always"  GrowBy="0.1,0.1"/>
    </s3D:SciChart3DSurface.ZAxis>
    
  5. Run the application again and hover the mouse over the same chart. Note that the tooltop is now shown for a data point different to whichever one the mouse is over at the time, which is incorrect.

I am trying to produce a ScatterChart that has point markers colors that are dependent on a list of color datapoints. I have created a custom IPointMarkerPaletteProvider that has the PointPaletteinfo function defined as:

    public PointPaletteInfo? OverridePointMarker(IRenderableSeries series, int index, IPointMetadata metadata)
    {

        return new PointPaletteInfo()
        {
            Fill = ((BondMetaData)metadata).Color,
            Stroke = ((BondMetaData)metadata).Color,

        };
    }

It works, however, the panning feature becomes extremely laggy as though it is resetting the color of every point everytime the chart is moved.

What should I do to improve the performance?

I am trying to make a custom Label Provider by extending NumericLabelProvider as it is described here:
https://www.scichart.com/documentation/android/current/webframe.html#Axis%20Labels%20-%20LabelProvider%20API.html

private class PercentLabelProvider : NumericLabelProvider
{
    public override string FormatLabel(Java.Lang.IComparable dataValue)
    {
        return string.Format("{0:P0}", dataValue);
    }
}

However, this is not possible, because FormatLabel can not be overridden.
This is the error message:
“cannot override inherited member ‘FormatterLabelProviderBase.FormatLabel(IComparable)’ because it is not marked virtual, abstract, or override”

DateLabelProvider has the same problem.

I need need to use both.

Is there a solution for this issue?

On Android, the docs say that AnnotationSurfaceEnum should have the “BelowChart” enum case, but it is actually missing in the code. It is there on iOS but not on Android.

I need this particular enum case, because otherwise the annotation boxes are hiding the data series and the grid lines.

What should I do?

I created a CustomRenderableSeries to put TextAnnotations on surface for every drawn point.

I discovered that Draw method is not called when no points are to be drawn in the visible range, so i can’t do any cleanup of the annotations i created in a previous pass.

Is there a way to force Draw method to be called anyway upon surface redraw (for example when zooming)?

Thank you

My issue is that the Pointmarker does not draw when I attempt to implement a custom renderable series view model. I’ve isolated it to the fact I am subclassing because the same code will draw if I replace my custom subclass with the base class.

I subclassed XyScatterRenderableSeriesViewModel like so:

public class CustomSeriesViewModel : XyScatterRenderableSeriesViewModel
{
    public CustomSeriesViewModel ()
    : base()
    {
    }
}

It is created like this:

return new CustomSeriesViewModel ()
        {
            // Note: the Pointmarker is created in the Xaml. See styles.
            StyleKey = "CustomSeriesStyle",
            DataSeries = dataSeries,
            IsSelected = true,
        };

And added into a list of type List IRenderableSeriesViewModel

If I replace the line new CustomSeriesViewModel () with new XyScatterRenderableSeriesViewModel(), the Pointmarker is drawn successfully. This is confusing to me, as there’s no other code in the subclass than the constructor, so I would expect it to be substitutable.

The style is responsible for defining the Pointmarker and looks like this:

 <Style x:Key="CustomSeriesStyle" TargetType="s:BaseRenderableSeries" >
    <Setter Property="s:TooltipModifier.TooltipTemplate" Value="{StaticResource CustomTooltipTemplate}" />
    <Setter Property="s:TooltipModifier.TooltipContainerStyle" Value="{StaticResource CustomTooltipStyle}" />
    <Setter Property="PointMarker">
        <Setter.Value>
            <s:SpritePointMarker>
                <s:SpritePointMarker.PointMarkerTemplate>
                    <ControlTemplate>
                        <Grid>
                            <Ellipse Width="13" Height="13" Fill="White"/>
                            <Ellipse Width="9" Height="9" Fill="{StaticResource CustomBrush}"/>
                        </Grid>
                    </ControlTemplate>
                </s:SpritePointMarker.PointMarkerTemplate>
            </s:SpritePointMarker>
        </Setter.Value>
    </Setter>
</Style>

Hi, I want to draw a chart like the attached image.

This is a chart with XyDataSeries, it show as vertical line at each data point and verticle line is a dotted line in order to separated from other series.
Since the OHLC chart will have the open, close on the data point and an impulse chart is forced to draw from an axis, is there any better way that can achieve a series like this? Thank you!

Good morning,

i need to draw a bitmap (specifically a RenderTargetBitmap object) to a surface during a Draw method of a CustomRenderableSeries, so using the IRenderContext2D argument.

I see there is a DrawTexture method but can’t find any example on this.
Can you provide a snippet to show the correct use of this method?

Thank you.

I’ve just downloaded the new v6 SDK and tried to use the tooltip feature both in my existing application and in the examples suite, and in both cases tooltips do not appear at all. The example suite for both .NET Framework and .NET Core crashes and the solution export feature produces a solution that does not build in Visual Studio.

The first example, 3D Charts -> Tooltips and Hit Test 3D Charts -> Series Custom Tooltips 3D Chart, crashes the example suite if I hover over a data point. The application closes with no error message.

The second example, 3D Charts -> Tooltips and Hit Test 3D Charts -> Series Tooltips 3D Chart, does not show any tooltips at all, in contrast to the same example from the v5 example suite. The application in this case does not crash, though.

In my own application the tooltip does not show whereas with the previous version of SciChart it did. I cannot see an exception raised.

Dear SciChart Team:

I have two questions to ask:

Question 1

I can use renderableSeries.PointMarker, like this:

renderableSeries.PointMarker = new EllipsePointMarker()
                            {
                                Fill = Colors.LightSteelBlue,
                                Stroke = Colors.White,
                                StrokeThickness = POINTMARKER_STROKETHICKNESS,
                                Width = POINTMARKER_WIDTH,
                                Height = POINTMARKER_HEIGHT,
                            };

But I only want to set some points to PointMarker, not all points. How can i do?

Question 2

I want to drag data-points, and I have referenced this example: Custom ChartModifiers – Select and drag a point
But I only want to move the specified data points, not all the points. What should I do?

We are using HorizontalLineAnnotation and VerticalLineAnnotations on a chart. We have subclassed these classes so that we could use our own AnnotationLabels that display text instead of the value of the line position.

something like this:

`
<s:HorizontalLineAnnotation.Resources>

</s:HorizontalLineAnnotation.Resources>

<s:HorizontalLineAnnotation.Stroke>
    <SolidColorBrush Color="{Binding Color}"/>
</s:HorizontalLineAnnotation.Stroke>

<s:HorizontalLineAnnotation.ToolTip>
    <ToolTip Content="{Binding Label}"  
             Visibility="{Binding Label, Converter={StaticResource EmptyStringToVisibilityCollapsedConverter}}"/>
</s:HorizontalLineAnnotation.ToolTip>

<s:AnnotationLabel x:Name="_annotationLabel" LabelPlacement="Axis" BorderThickness="0" Text="{Binding DataContext.Label}" 
Background="Transparent">
    <s:AnnotationLabel.Foreground>
        <SolidColorBrush Color="{Binding DataContext.Color}"/>
    </s:AnnotationLabel.Foreground>
</s:AnnotationLabel>

`

Now we want to use our own custom control similar to a TextBlock as the axis label. Is it possible to template the AnnotationLabel or maybe another way to accomplish this? The custom control we have is used to highlight part of the text in the textblock (using Runs) for search highlighting so even if we have to do it a different way, that would acceptable.

What I would like to do:
.
.
.

<s:AnnotationLabel x:Name="_annotationLabel" LabelPlacement="Axis" BorderThickness="0" Text="{Binding DataContext.Label}" Background="Transparent">
    <s:AnnotationLabel.Foreground>
        <SolidColorBrush Color="{Binding DataContext.Color}"/>
    </s:AnnotationLabel.Foreground>
    <s:AnnotationLabel.Style>
        <Style TargetType="s:AnnotationLabel">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="s:AnnotationLabel">
                        <controls:HighlightingTextBlock Text="{TemplateBinding Text}" HighlightedText="{Binding 
                                                                                                                    DataContext.HighlightedLabelText}"/>
                    </ControlTemplate>

Hello,
I want to use SubDayTextFormatting in android so that when the visible range reaches the same day, e.g. as I zoom, it switches from dd:MMM:yyyy to HH:mm.
How can I do that?

Hello

I was wondering if it would be possible to create a simple clean looking chart like described in the attached image. I am looking for a “SuccessRateChart” that has some similarity to the PieChart but does not use the whole circle to describe its content. I would also need a way to adjust the visible radius of the Pie. In means of information visualization you often hear the term “doughnut chart”…

On way could be to draw some circle stacked over the chart itself, but there should be a better solution.

Would love to hear from you,

Kind regards,
Stephan

Hello 🙂

We have a chart setup like in the Custom Overview Control example. The RenderableSeries property of both charts is bound to the same ObservableCollection of IRenderableSeries. So if I change a property of the series like the thickness or point marker the change is visible in both charts accordingly.
Is there an easy way to accomplish that the series is drawn only with default thickness and without a point marker in the overview chart but with a point geometry and thickness in the main chart ?

Thank you.

Hi all,

I’m currently evaluating SciChart for use within our company. While trying to preserve our current chart look and feel, I noticed that the border settings for the GridLinesPanelStyle do not seem to be working.
I was just following the theming and styling tutorial, where a border is added to the GridLinesPanel and is clearly visible in the screenshot of the theming and styling demo in the tutorial. After noticing this, I opened up the demo application myself and noticed that also in the demo the border is not showing up.

Is this a known issue? And if so, what is a possible work-around for this?

Thanks in advance,
Cédric

I’m using Xamarin.iOS and the SciChart.iOS NuGet. When adding a LabelProvider to an axis the iPhoneSimulator with iOS 13.2 crashes without warning or exception back to the phone menu. This issue is not present on Android using the same API usage pattern.

This effect is not just in my own apps but can be replicated by running the latest Examples app on the same simulator. Examples which demonstrate the same behaviour include “Custom Theme”, Stacked Column Side by Side Chart”, “Using Theme Manager”, all of which set the LabelProvider in the source code.

Is this a known bug? Maybe an incompatibility with the latest version of Xamarin.iOS.

I noticed that this issue has been reported before.

This is a deal breaker for us at the moment as formatting axis labels is pretty crucial.
