如何在LiveCharts中让多个Y轴都从0开始？

var chart = new LiveCharts.WinForms.CartesianChart();

var yAxis1 = new Axis();
yAxis1.Title = "Y轴1";
yAxis1.MinValue = 0;

var yAxis2 = new Axis();
yAxis2.Title = "Y轴2";
yAxis2.MinValue = 0;

chart.AxisY.Add(yAxis1);
chart.AxisY.Add(yAxis2);

var series1 = new LineSeries
{
    Title = "数据序列1",
    Values = new ChartValues<double> { 1, 2, 3, 4, 5 },
    ScalesYAt = 0
};

var series2 = new LineSeries
{
    Title = "数据序列2",
    Values = new ChartValues<double> { 10, 20, 30, 40, 50 },
    ScalesYAt = 1
};

chart.Series.Add(series1);
chart.Series.Add(series2);

this.Controls.Add(chart);
