我有以下XAML
定义:
<Charting:Chart x:Name="ColumnChart"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Width="Auto"
Height="Auto"
Padding="50"
Title="100 random numbers">
<Charting:ColumnSeries Title="Skills"
IndependentValuePath="Name"
DependentValuePath="Pts"
IsSelectionEnabled="True">
</Charting:ColumnSeries>
</Charting:Chart>
如何旋转标签(让我们说-90度)以使它们更具可读性?
答案 0 :(得分:3)
可以旋转标签。它需要几个步骤,不幸的是,由于WinRT XAML布局中缺少一个特性,可能是一个自定义类。
找到核心理念here。
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Charting:Chart x:Name="ColumnChart"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Padding="50"
Title="100 random numbers">
<Charting:ColumnSeries Title="Skills" x:Name="theColumnSeries"
IndependentValuePath="Name"
DependentValuePath="Pts"
IsSelectionEnabled="True">
<Charting:ColumnSeries.IndependentAxis>
<Charting:CategoryAxis Orientation="X">
<Charting:CategoryAxis.AxisLabelStyle>
<Style TargetType="Charting:AxisLabel">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Charting:AxisLabel">
<TextBlock Text="{TemplateBinding FormattedContent}">
<TextBlock.lay
<TextBlock.RenderTransform>
<RotateTransform Angle="-60" />
</TextBlock.RenderTransform>
</TextBlock>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Charting:CategoryAxis.AxisLabelStyle>
</Charting:CategoryAxis>
</Charting:ColumnSeries.IndependentAxis>
</Charting:ColumnSeries>
</Charting:Chart>
</Grid>
我使用的C#代码:
public sealed partial class MainPage : Page
{
public MainPage()
{
this.InitializeComponent();
this.Loaded += MainPage_Loaded;
}
void MainPage_Loaded(object sender, RoutedEventArgs e)
{
var rnd = new Random(444);
ObservableCollection<Demo> values = new ObservableCollection<Demo>();
for (int i = 0; i < 15; i++)
{
values.Add(new Demo() { Name = (rnd.NextDouble() * 100).ToString(), Pts = i });
}
((ColumnSeries)ColumnChart.Series[0]).ItemsSource = values;
}
}
class Demo
{
public string Name { get; set; }
public double Pts { get; set; }
}
但不幸的是,它并不完全是你想要的。问题是没有像WPF中存在的LayoutTransform。如果您运行上面显示的代码,标签将被旋转,但它们将与其他内容重叠。
该博客的作者编写了一个LayoutTransformer类可以帮助解决问题,虽然它是为Silverlight设计的(因此它可以是可移植的并且可以与WinRT XAML一起使用)。
