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
}

您可以使用对数刻度配置您的y轴 - 有关如何在实时图表网站https://lvcharts.net/App/examples/v1/wpf/Logarithmic%20Scale
上执行此操作的说明以下是适用于列系列的示例:
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;
}
和XAML:
<Grid>
<lvc:CartesianChart Series="{Binding SeriesCollection}">
<lvc:CartesianChart.AxisY>
<lvc:LogarithmicAxis Base="10" />
</lvc:CartesianChart.AxisY>
</lvc:CartesianChart>
</Grid>
