缩放变换，一次放大（x，y）方向

Question

我在画布上有图表。当我点击图表我希望它缩放。我有这个代码。

<Canvas x:Name="SampleCanvas" Background="#F5F7F9"    MouseLeftButtonDown="brdMovable_MouseLeftButtonDown" MouseLeftButtonUp="brdMovable_MouseLeftButtonUp" MouseMove="brdMovable_MouseMove" Height="570" Width="875">
<chartingToolkit:Chart  x:Name="mcChart" Loaded="mcChart_Loaded"  Width="400" Height="250"  Canvas.Left="185" Canvas.Top="5"
     Background="LightSteelBlue">
    <chartingToolkit:Chart.RenderTransform>
        <ScaleTransform x:Name="scaleTransform"></ScaleTransform>
    </chartingToolkit:Chart.RenderTransform>
    <chartingToolkit:Chart.Series>
        <chartingToolkit:ColumnSeries Title="Experience"  IndependentValueBinding="{Binding Path=ModelName}" DependentValueBinding="{Binding  Path=SaleCount}">
        </chartingToolkit:ColumnSeries>
    </chartingToolkit:Chart.Series>
</chartingToolkit:Chart> 

在

背后的代码中

                Storyboard storyBoard = new Storyboard();

                ///////// X Transform
                DoubleAnimation ds = new DoubleAnimation();
                storyBoard.Children.Add(ds);
                ds.From  = 1;
                ds.To = 1.5;
                ds.Duration = new Duration(TimeSpan.FromSeconds(2));
                Storyboard.SetTargetName(ds, "scaleTransform");
                Storyboard.SetTargetProperty(ds, new PropertyPath("(ScaleX)"));

                ////Y Transform

                DoubleAnimation dsy = new DoubleAnimation();
                storyBoard.Children.Add(dsy);
                dsy.From = 1;
                dsy.To = 1.5;
                ds.Duration = new          Duration(TimeSpan.FromSeconds(3));
                Storyboard.SetTargetName(dsy, "scaleTransform");
                Storyboard.SetTargetProperty(dsy, new PropertyPath("(ScaleY)"));
                LayoutRoot.Resources.Remove("unique_id");
                LayoutRoot.Resources.Add("unique_id",storyBoard);

                storyBoard.Begin();

这首先在x方向显示输出，然后在y方向显示，但我一次想要两个方向。我们怎么能这样做？

感谢。

我花了一点时间发现明显的情况:)你已经设置了第一个动画的持续时间两次（并且持续时间不同）。

应该是：

dsy.Duration = new Duration(TimeSpan.FromSeconds(2));

不是

ds.Duration = new Duration(TimeSpan.FromSeconds(3));
