[英]LiveCharts: how to plot skewed data (i.e exponential y-axis) in column series wpf
How to set the Y-axis interval exponentially in column series? 如何在列系列中以指数方式设置Y轴间隔?
new ColumnSeries
{
Fill = new SolidColorBrush(Color.FromRgb(30,130,173)),
Width = 100,
MaxColumnWidth = 100,
Values = new ChartValues<double> {500,30,10},
DataLabels = true,
LabelPoint = point => point.Y +"",
FontSize = 20
}
You can configure your y-axis with a logarithmic scale - there's an explanation of how to do this on the Live Charts site https://lvcharts.net/App/examples/v1/wpf/Logarithmic%20Scale 您可以使用对数刻度配置y轴-在实时图表网站https://lvcharts.net/App/examples/v1/wpf/Logarithmic%20Scale中有关于如何执行此操作的说明
Here's an example adapted for a column series: 这是适合列系列的示例:
public SeriesCollection SeriesCollection { get; set; }
public MainWindow()
{
InitializeComponent();
var mapper = Mappers.Xy<double>()
.X((value, index) => index)
.Y((value, index) => Math.Log(value, 10));
SeriesCollection = new SeriesCollection(mapper)
{
new ColumnSeries
{
Values = new ChartValues<double>{500,30,10}
}
};
DataContext = this;
}
and the XAML: 和XAML:
<Grid>
<lvc:CartesianChart Series="{Binding SeriesCollection}">
<lvc:CartesianChart.AxisY>
<lvc:LogarithmicAxis Base="10" />
</lvc:CartesianChart.AxisY>
</lvc:CartesianChart>
</Grid>
