有没有办法直接关闭Xaml中的动画?动画真的很迟钝,因为我的图表有很多分数。

我已在http://wpf.codeplex.com/SourceControl/list/changesets

下载了最新的源代码

我的想法是,通过更改不同图表系列的样式(图表点,DataPointStyle)来删除动画

charting:PieDataPoint

的示例

尝试删除所显示数据的动画,并使用给定的键(x:key =“myStyle” - > DataPointStyle="{StaticResource myStyle}"

采用自己的风格

并在Opacity="0"

删除<Grid x:Name="Root" Opacity="0">

从您的样式中删除此可视状态组

<VisualStateGroup x:Name="RevealStates">
    <VisualStateGroup.Transitions>
        <VisualTransition GeneratedDuration="0:0:0.5" />
    </VisualStateGroup.Transitions>
    <VisualState x:Name="Shown">
        <Storyboard>
            <DoubleAnimation Storyboard.TargetName="Root" Storyboard.TargetProperty="Opacity" To="1" Duration="0" />
        </Storyboard>
    </VisualState>
    <VisualState x:Name="Hidden">
        <Storyboard>
            <DoubleAnimation Storyboard.TargetName="Root" Storyboard.TargetProperty="Opacity" To="0" Duration="0" />
        </Storyboard>
    </VisualState>
</VisualStateGroup>

修改

这是改变的风格。

<!--  charting:PieDataPoint  -->
<Style TargetType="charting:PieDataPoint">
    <Setter Property="Background" Value="Orange" />
    <Setter Property="BorderBrush" Value="White" />
    <Setter Property="BorderThickness" Value="1" />
    <Setter Property="IsTabStop" Value="False" />
    <Setter Property="RatioStringFormat" Value="{}{0:p2}" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="charting:PieDataPoint">
                <Grid x:Name="Root" Opacity="0">
                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup x:Name="CommonStates">
                            <VisualStateGroup.Transitions>
                                <VisualTransition GeneratedDuration="0:0:0.1" />
                            </VisualStateGroup.Transitions>
                            <VisualState x:Name="Normal" />
                            <VisualState x:Name="MouseOver">
                                <Storyboard>
                                    <DoubleAnimation Storyboard.TargetName="MouseOverHighlight" Storyboard.TargetProperty="Opacity" To="0.6" Duration="0" />
                                </Storyboard>
                            </VisualState>
                        </VisualStateGroup>
                        <VisualStateGroup x:Name="SelectionStates">
                            <VisualStateGroup.Transitions>
                                <VisualTransition GeneratedDuration="0:0:0.1" />
                            </VisualStateGroup.Transitions>
                            <VisualState x:Name="Unselected" />
                            <VisualState x:Name="Selected">
                                <Storyboard>
                                    <DoubleAnimation Storyboard.TargetName="SelectionHighlight" Storyboard.TargetProperty="Opacity" To="0.6" Duration="0" />
                                </Storyboard>
                            </VisualState>
                        </VisualStateGroup>
                    </VisualStateManager.VisualStateGroups>
                    <Path x:Name="Slice" Data="{TemplateBinding Geometry}" Fill="{TemplateBinding Background}" Stroke="{TemplateBinding BorderBrush}" StrokeMiterLimit="1">
                        <ToolTipService.ToolTip>
                            <StackPanel>
                                <ContentControl Content="{TemplateBinding FormattedDependentValue}" />
                                <ContentControl Content="{TemplateBinding FormattedRatio}" />
                            </StackPanel>
                        </ToolTipService.ToolTip>
                    </Path>
                    <Path x:Name="SelectionHighlight" Data="{TemplateBinding GeometrySelection}" Fill="Red" StrokeMiterLimit="1" IsHitTestVisible="False" Opacity="0" />
                    <Path x:Name="MouseOverHighlight" Data="{TemplateBinding GeometryHighlight}" Fill="White" StrokeMiterLimit="1" IsHitTestVisible="False" Opacity="0" />
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

在我第一次尝试删除动画后,我想放弃,因为它没有用。

然后我用源代码的反射器看着我,并找到了一种方法,它仍然有效。

遗憾的是,设置DataPointStyle是不够的,我认为这是一个错误。

<chartingToolkit:Chart Margin="8">

  <chartingToolkit:Chart.Series>
    <chartingToolkit:BarSeries x:Name="barSeries"
                                Title="Experience"
                                DataPointStyle="{StaticResource myBarStyle}">
    </chartingToolkit:BarSeries>
  </chartingToolkit:Chart.Series>

</chartingToolkit:Chart>

在包含图表的控件的构造函数中,只需执行以下操作。

this.barSeries.RefreshStyles();

希望这会有所帮助
