样条图平滑拐角

我在我的项目中使用 .NET 框架中的图表控件。我已将图表控件添加到表单中并进行配置，如下所示。

// Add a new series.
chart1.Series.Add("1");
var series = chart1.Series[0];
series.ChartType = SeriesChartType.Spline;
// Hide the legend.
series.IsVisibleInLegend = false;

// configure x axis.
var cArea = chart1.ChartAreas[0];
cArea.AxisX.IntervalType = DateTimeIntervalType.Number;

cArea.AxisX.LabelStyle.Format = "00";
cArea.AxisY.LabelStyle.Format = "0.000";
cArea.AxisY.LabelStyle.IsEndLabelVisible = true;

cArea.AxisX.Minimum = 0;
cArea.AxisX.Maximum = 100;
cArea.AxisX.Interval = 20;

cArea.AxisY.Minimum = 0;
cArea.AxisY.Maximum = 100;
cArea.AxisX.Interval = 20;

数据点值如下：

chart1.Series[0].Points.AddXY(0, 5);
chart1.Series[0].Points.AddXY(5, 10);
chart1.Series[0].Points.AddXY(10, 30);
chart1.Series[0].Points.AddXY(20, 100);
chart1.Series[0].Points.AddXY(30, 100);
chart1.Series[0].Points.AddXY(40, 90);
chart1.Series[0].Points.AddXY(50, 80);

For the above data points, series is not smooth. Upper edge is getting cut. Refer attached image.

如何使其平滑以便整条线可见？

不可见因为平滑，调整比例（使用cArea.AxisX.Maximum = 150;例如）或删除平滑以使整个曲线可见。
