LiveCharts 中运行时的多轴
Multiple Axis at Runtime in LiveCharts
我正在尝试编写一个 WPF 应用程序来为我拥有的一系列数字绘制折线图。这些数字列在 .CSV 文件中，我将在 运行 时阅读该文件。因此，我不知道我将拥有的系列数，也不知道每个系列的 max/min 值。
为了演示和简洁起见，请看下面的示例。将这些系列值视为我将从我的实际应用程序中的 .CSV 文件中读取的值。
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
SeriesCollection = new SeriesCollection
{
new LineSeries
{
Title = "Series 1",
Values = new ChartValues<double> { 4, 66, 5, 2, 4 },
},
new LineSeries
{
Title = "Series 2",
Values = new ChartValues<double> { 6, 7, 3, 4, 6 },
},
new LineSeries
{
Title = "Series 3",
Values = new ChartValues<double> { 4, 2, 7, 2, 7 },
}
};
DataContext = this;
}
public SeriesCollection SeriesCollection { get; set; }
}
我的XAML看起来很简单，像这样：
<Window x:Class="WPFCharts.MainWindow"
...
Title="MainWindow" Height="450" Width="800">
<Grid>
<lvc:CartesianChart Series="{Binding SeriesCollection}"/>
</Grid>
</Window>
如您所见，如果我使用默认 LiveCharts 设置将其绘制在折线图中，则一个系列中的一个值与其他值相比超出了图表：
所以我想给用户机会把这样的折线图放在他们自己的坐标轴上。通过阅读 LiveCharts 文档，我发现 as shown here，您可以使用 ScaleXAt 和 ScaleYAt 属性将不同的线系列放在不同的轴上。
然而，该示例在 XAML 中设置了轴，而我想动态地执行此操作。所以我尝试在后面的代码中设置上述 属性 ，如下所示：
SeriesCollection = new SeriesCollection
{
new LineSeries
{
Title = "Series 1",
Values = new ChartValues<double> { 4, 66, 5, 2, 4 },
ScalesYAt = 0
},
new LineSeries
{
Title = "Series 2",
Values = new ChartValues<double> { 6, 7, 3, 4, 6 },
ScalesYAt = 1
},
new LineSeries
{
Title = "Series 3",
Values = new ChartValues<double> { 4, 2, 7, 2, 7 },
ScalesYAt = 2
}
};
但是当我这样做时，运行 应用程序出现异常：
System.ArgumentOutOfRangeException: 'Index was out of range. Must be non-negative and less than the size of the collection.'
我在这里做错了什么？我如何使用代码设置它，而不是 XAML?
如果你想使用不同的Y轴，那么你需要声明它们，也许你错过了。所以你的模型会变成这样：
public class ViewModel
{
public ViewModel()
{
SeriesCollection = new SeriesCollection
{
new LineSeries
{
Title = "Series 1",
Values = new ChartValues<double> { 4, 66, 5, 2, 4 },
ScalesYAt = 0
},
new LineSeries
{
Title = "Series 2",
Values = new ChartValues<double> { 6, 7, 3, 4, 6 },
ScalesYAt = 1
},
new LineSeries
{
Title = "Series 3",
Values = new ChartValues<double> { 4, 2, 7, 2, 7 },
ScalesYAt = 2
}
};
AxisYCollection = new AxesCollection
{
new Axis { Title = "Y Axis 1", Foreground = Brushes.Gray },
new Axis { Title = "Y Axis 2", Foreground = Brushes.Red },
new Axis { Title = "Y Axis 3", Foreground = Brushes.Brown }
};
}
public AxesCollection AxisYCollection { get; set; }
public SeriesCollection SeriesCollection { get; set; }
}
而 XAML 将是：
<Grid>
<lvc:CartesianChart Series="{Binding SeriesCollection}" AxisY="{Binding AxisYCollection}" />
</Grid>
当然你需要设置一个ViewModel class的实例作为你的Window的DataContext:
public MainWindow()
{
vm = new ViewModel();
InitializeComponent();
DataContext = vm;
}
如果您不在绑定 AxesCollection 中声明 "enough" 轴，将找不到它在 n 索引处的元素，您将陷入 ArgumentOutOfRangeException.希望对你有帮助。
我正在做类似的事情；现在一团糟，我把它作为一种学习经验。

我正在尝试编写一个 WPF 应用程序来为我拥有的一系列数字绘制折线图。这些数字列在 .CSV 文件中，我将在 运行 时阅读该文件。因此，我不知道我将拥有的系列数，也不知道每个系列的 max/min 值。
