LiveCharts:如何绘制扭曲的数据(i)。e指数y轴)在列系列wpf中。

How to set the Y-axis interval exponentially in column series?

如何在列级数中指数地设置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

你可以用对数尺度来配置你的y轴——有一个关于如何在实时图表网站https://lvcharts.net/app/examples/v1/wpf/logmic%20scale上做到这一点的解释

Here's an example adapted for a column series:

下面是一个适合于列系列的示例:

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;
}

and the XAML:

XAML:

<Grid>
    <lvc:CartesianChart Series="{Binding SeriesCollection}">
        <lvc:CartesianChart.AxisY>
            <lvc:LogarithmicAxis Base="10" />
        </lvc:CartesianChart.AxisY>
    </lvc:CartesianChart>
</Grid>
