创建新图表并添加系列(例如ColumnSeries)以及数据时,列将呈现为一种FadeIn动画,并在屏幕上绘制图表后立即显示。
有没有阻止这个动画发生?或者,无论如何强制图表在渲染之前完成动画?

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
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}"
)
并在Opacity="0"
<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>

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">

<VisualTransition GeneratedDuration="0:0:0.1" />
</VisualStateGroup.Transitions>
<VisualState x:Name="Normal" />
<VisualState x:Name="MouseOver">

<DoubleAnimation Storyboard.TargetName="MouseOverHighlight" Storyboard.TargetProperty="Opacity" To="0.6" Duration="0" />
</Storyboard>
</VisualState>
</VisualStateGroup>

</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
