How can i use bulletgragh?

My license version is 2018.2.620.45

I can't use RadHorizontalBulletGraph control even if I add reference Telerik.Windows.Controls.DataVisualization.

There is an error ''QualitativeRanges' property does not support the value of the 'QualitativeRange' format.'

I can't use that control even if drag and drop.

If i delete 'QualitativeRanges' property, I can't see that control.

So, what should i do?

Customizing BulletGraph

Hi,

I'd like to know if it is possible to customize some aspects of the BulletGraph control:

1. When I set the value of Minimum property to a value higher than zero, an oval is shown instead of the bar for the FeaturedMeasure, is it possible to show the bar even when the Minimum property value is higher than zero?

2. Is it possible to hide the axis of values?

3. Is it possible to change the width of the FeaturedMeasure bar? I am using a RadVerticalBulletGraph.

Thanks,

Alberto Martinez

Bullet chart reference line in cluster chart

Hello ,

I have a cluster Bar series with 2 clusters or may 3 clusters. Now I want one more reference line, like we have on the bullet chart on these clustered bar series. Is it possible in telerik? . I think its combining the cluster bar series feature and reference line feature of bullet chart.

Please see the attachment of the kind of graph I am expecting.

BulletGraph Programmatically

Hi, I am new using Telerik controls and WPF, I saw the executive dashboard demo and I would like to create a chart like the one showing sales by product. I am reviewing the code but I don´t really understad it, I think the control that is used is a BulletGraph.

There is this Page where you can see how to create a BulletGraph, but I don't know how to show the lines for the actual value and the target value.

Does anyone have an example to achieve a chart like that one?

Thanks,

Alberto

Dragable ComparativeMeasure and other regions

I know there is not direct support to allow dragging of the ComparitiveMeasure line in BulletGraph. However what I'd like to know if it is possible to do this via some kind of workaround?

Thanks,

QualitativeRange binding doesn't work

Hello,
I am attempting to use a RadVerticalBulletGraph but there is a problem with the QualitativeRange object.I am attempting to implement a BulletGraph in an MVVM pattern such that the ViewModel only needs to provide the Value while the Brush is specified within the XAML (via styling). So my requiements are:

1. QualitativeRange Brush defined in XAML
2. QualitativeRange Value bound to a property on the ViewModel

Unfortunately this appears to be impossible. All working examples I've been able to find either create the QualitativeRange objects in code behind (unacceptable due to the color being defined in code) or have the value and brush hard coded (also unacceptable due to the binding requirement).

If anyone is able to provide an example that meets my two requirements I would be extremely grateful to see it. Thanks,
Jason

Comparative Measure with label

I would like to add some static text to the Comparative Measure element. I have re-templated the bullet graph, but my attempts to add the text does not seem to work. I would like the text to float at the top right of the line. Is this possible?

Here is my style template:

<Style x:Key="RadHorizontalBulletGraphStyle" TargetType="telerik:RadHorizontalBulletGraph">

<Setter Property="ComparativeMeasureThickness" Value="1"/>

<Setter Property="FontSize" Value="10"/>

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="telerik:RadHorizontalBulletGraph">

<Grid>

<Grid.RowDefinitions>

<RowDefinition Height="5*"/>

</Grid.RowDefinitions>

<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="White" Grid.Row="0">

<Grid>

<Grid.Resources>

<Style TargetType="telerik:BarItem">

<Setter Property="LengthPercent" Value="1" />

</Style>

</Grid.Resources>

<Grid.RowDefinitions>

<RowDefinition Height="5*" />

</Grid.RowDefinitions>

<telerik:FeaturedMeasurePresenter Grid.Row="0" Content="{TemplateBinding FeaturedMeasureInternal}" Margin="0,5" />

<telerik:FeaturedMeasurePresenter Grid.Row="1" Content="{TemplateBinding ProjectedMeasureInternal}" Margin="0,5" />

</Grid>

<StackPanel HorizontalAlignment="Stretch">

<telerik:ComparativeMeasuresContainer ChildrenSource="{TemplateBinding MergedComparativeMeasures}" Range="{TemplateBinding Range}" Margin="-15" />

</StackPanel>

</Grid>

</Border>

<telerik:QuantitativeScaleContainer Grid.Row="1" TextFormatString="{TemplateBinding TextFormatString}" Visibility="{TemplateBinding QuantitativeScaleVisibility}" Opacity="0.5" RenderTransformOrigin="0.5,0.5" Range="{TemplateBinding Range}" >

<telerik:QuantitativeScaleContainer.RenderTransform>

<TranslateTransform Y="5"/>

</telerik:QuantitativeScaleContainer.RenderTransform>

</telerik:QuantitativeScaleContainer>

</Grid>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

<SolidColorBrush x:Key="ActualBrush" Color="Green" />

<SolidColorBrush x:Key="TargetBrush" Color="Red" />

And here is my control definition:

<telerik:RadHorizontalBulletGraph TextFormatString="${0}"

ProjectedValue="150"

FeaturedMeasure="200"

ComparativeMeasure="175"

Height="100"

Style="{StaticResource RadHorizontalBulletGraphStyle}"

FeaturedMeasureBrush="{StaticResource ActualBrush}"

ProjectedValueBrush="{StaticResource TargetBrush}"

Step="200" />

NullReferenceException when navigating away from BulletGraph

Hi,

I'm using a TileView and have a RadHorizontalBulletGraph that I only display when the TileView item is in the maximized state. When I maximize an item, the bullet graph displays correctly, but when I go to minimize the item, I get a NullReferenceException. There's not much of a stack trace, but here it is:

   at System.Windows.StyleHelper.FindNameInTemplateContent(DependencyObject container, String childName, FrameworkTemplate frameworkTemplate)
   at System.Windows.TemplateNameScope.System.Windows.Markup.INameScope.FindName(String name)
   at System.Windows.FrameworkElement.FindName(String name)
   at Telerik.Windows.Controls.ChildrenOfTypeExtensions.GetChildByName(FrameworkElement element, String name) in c:\TB\117\WPF_Scrum\Release_WPF_40\Sources\Development\Core\Controls\Extensions\ChildrenOfTypeExtensions.cs:line 42
   at Telerik.Windows.Controls.BulletGraph.RadBulletGraphBase.ToggleAxis() in c:\TB\117\WPF_Scrum\Release_WPF_40\Sources\Development\Controls\DataVisualization\BulletGraph\Base\RadBulletGraphBase.cs:line 925
   at Telerik.Windows.Controls.BulletGraph.RadBulletGraphBase.SynchronizeFeaturedMeasures() in c:\TB\117\WPF_Scrum\Release_WPF_40\Sources\Development\Controls\DataVisualization

Here's a simplified version of my XAML. Any ideas?

<DataTemplate x:Key="MachineTileLarge">

<Grid>

<Grid.RowDefinitions>

<RowDefinition/>

</Grid.RowDefinitions>

<telerik:RadHorizontalBulletGraph Grid.Row="1" Maximum="100"

ComparativeMeasureBrush="CornflowerBlue" FeaturedMeasureBrush="SeaGreen"

ComparativeMeasure="32" FeaturedMeasure="75" />

</Grid>

</DataTemplate

>

<DataTemplate x:Key="MachineTemplate">
    <telerik:RadFluidContentControl ContentChangeMode="Manual" TransitionDuration="0:0:.5"
        State="{Binding State, Converter={StaticResource tileConverter}}"
        SmallContentTemplate="{StaticResource MachineTileSmall}"
        ContentTemplate="{StaticResource MachineTileNormal}"
        LargeContentTemplate="{StaticResource MachineTileLarge}" />
</DataTemplate>
 
<Style TargetType="telerik:RadTileView">
    <Setter Property="PreservePositionWhenMaximized" Value="True" />
    <Setter Property="telerik:TileViewPanel.IsVirtualized" Value="True" />
    <Setter Property="IsAutoScrollingEnabled" Value="True" />
    <Setter Property="TileStateChangeTrigger" Value="SingleClick" />
    <Setter Property="MinimizedColumnWidth" Value="200" />
    <Setter Property="MinimizedRowHeight" Value="225" />
    <Setter Property="RowHeight" Value="330" />
    <Setter Property="ColumnWidth" Value="290" />
    <Setter Property="ContentTemplate" Value="{StaticResource MachineTemplate}" />
    <Setter Property="ItemTemplate" Value="{StaticResource MachineTileHeader}" />
</Style>
 
<telerik:RadTileView ItemsSource="{Binding Path=MachineStatusItems}"                                    
     TileStateChanged="tileView_TileStateChanged"
     TileStateChangeTrigger="SingleClick"
     MaximizeMode="ZeroOrOne"
     IsItemDraggingEnabled="True"
     PreservePositionWhenMaximized="True"/>

QualitativeRange Error on Binding

Hello,

in my scenario i try to visualize the variance of a production cyle within a radgridview. For this i want to show a warning/error range.

<telerik:RadHorizontalBulletGraph Width="150" Height="20"

QuantitativeScaleVisibility="Collapsed"

FlowDirection="LeftToRight"

FeaturedMeasure="{Binding Input0TimeLast}"

ComparativeMeasure="{Binding Auftrag.ZyklusIstSoll}">

<telerik:RadHorizontalBulletGraph.QualitativeRanges>

<telerik:QualitativeRange Brush="Red" Value="{Binding ZyklusErrorBound}" />

<telerik:QualitativeRange Brush="Yellow" Value="{Binding ZyklusWarningBound}" />

<telerik:QualitativeRange Brush="Green" Value="{Binding ZyklusOkBound" />

</telerik:RadHorizontalBulletGraph.QualitativeRanges>

</telerik:RadHorizontalBulletGraph>

public int ZyklusErrorBound

{

get

{

var x = this.Auftrag.ZyklusIstSoll - this.Auftrag.ZyklusIstToleranz;

return x;

}

public int ZyklusWarningBound

{

get

{

var x = this.Auftrag.ZyklusIstSoll - (this.Auftrag.ZyklusIstToleranz / 2);

return x;

}

When i bind the three QualitativeRange`s i get a exception "Sequence contains no elements". If i set instead of ZyklusOkBound a fixed value for example, no exceptions is thrown. But the two other values are not called from my Itemssource (i´ve checked that by setting a breakpoint on my getters). Instead of a message shows up in my console:

System.Windows.Data Error: 2

:
Cannot find govening FrameworkElement or FrameworkContentElement for
target element. BindingExpression:Path=ZyklusWarningBound;
DataItem=null; target element is

'QualitativeRange' (HashCode=7579691); target property is 'Value' (type 'Double')

System.Windows.Data Error: 2

: Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=ZyklusErrorBound; DataItem=null; target element is

'QualitativeRange' (HashCode=7579691); target property is 'Value' (type 'Double')

What is absolutely remarkable, if i bind ZyklusErrorBound or ZyklusWarningBound to FeaturedMeasure the value is retrieved..

Thanks in advance for your help.
