我正在尝试自定义系列具有的 ASP Web 表单 RadChart 的外观，FillType = Solid同时仍然允许在较大的点值后面看到较小的点值。我真正想要的是每个系列都在所有填充顶部放置一个轮廓（基本上是在 aChartSeriesType.Line顶部放置的效果ChartSeriesType.Area）。

我已经尝试过设置LineAppearance.Shadow、颜色透明度以及它们的组合，但仍然很难辨别背景系列值。

使用实心填充时是否没有一种简单的方法可以为每个系列打开轮廓？或者只设置背景填充的透明度，而不是边缘？

在此处输入图像描述

注意上图中的透明度。恐怕允许更高的透明度会提高背景值的可见性，但会导致可怕的柔和颜色集合。

我建议您浏览telerik文档页面RadControls for ASP.NET AJAX Documentation -Styling Chart Elements和这个很好的示例以编程方式创建 RadChart - 更复杂的示例。

代码片段：

// Define chart and titleRadChart radChart = new RadChart();
radChart.ChartTitle.TextBlock.Text = "My RadChart";
radChart.ChartTitle.TextBlock.Appearance.TextProperties.Color = System.Drawing.Color.Blue;
// Define chart series
ChartSeries chartSeries = new ChartSeries();
chartSeries.Appearance.LabelAppearance.Visible = false;
chartSeries.Name = "GDP";
chartSeries.Type = ChartSeriesType.Line;
chartSeries.Appearance.LineSeriesAppearance.Color = System.Drawing.Color.BlueViolet;
// Define the items in the series
chartSeries.AddItem(1);
chartSeries.AddItem(1.5);
chartSeries.AddItem(2.0);
chartSeries.AddItem(2.5);
chartSeries.AddItem(3.5);
// visually enhance the datapoints
chartSeries.Appearance.PointMark.Dimensions.AutoSize = false;
chartSeries.Appearance.PointMark.Dimensions.Width = 5;
chartSeries.Appearance.PointMark.Dimensions.Height = 5;
chartSeries.Appearance.PointMark.FillStyle.MainColor = System.Drawing.Color.Black;
chartSeries.Appearance.PointMark.Visible = true;
// Define chart series
ChartSeries chartSeries2 = new ChartSeries();
chartSeries2.Appearance.LabelAppearance.Visible = false;
chartSeries2.Name = "GNP";
chartSeries2.Type = ChartSeriesType.Line;
chartSeries2.Appearance.LineSeriesAppearance.Color = System.Drawing.Color.Green;
// Define the items in the series
chartSeries2.AddItem(2);
chartSeries2.AddItem(3);
chartSeries2.AddItem(3.5);
chartSeries2.AddItem(4);
chartSeries2.AddItem(4.5);
// visually enhance the data points
chartSeries2.Appearance.PointMark.Dimensions.AutoSize = false;
chartSeries2.Appearance.PointMark.Dimensions.Width = 5;
chartSeries2.Appearance.PointMark.Dimensions.Height = 5;
chartSeries2.Appearance.PointMark.FillStyle.MainColor = System.Drawing.Color.Black;
chartSeries2.Appearance.PointMark.Visible = true;
// set the plot area gradient background fill
radChart.PlotArea.Appearance.FillStyle.FillType = Telerik.Charting.Styles.FillType.Gradient;
radChart.PlotArea.Appearance.FillStyle.MainColor = System.Drawing.Color.FromArgb(65, 201, 254);
radChart.PlotArea.Appearance.FillStyle.SecondColor = System.Drawing.Color.FromArgb(0, 107, 186);
// Set text and line for X axis
radChart.PlotArea.XAxis.AxisLabel.TextBlock.Text = "Years";
radChart.PlotArea.XAxis.AxisLabel.TextBlock.Appearance.TextProperties.Color = System.Drawing.Color.Red;
radChart.PlotArea.XAxis.Appearance.Width = 3;
radChart.PlotArea.XAxis.Appearance.Color = System.Drawing.Color.Red;
// Set text and line for Y axis
radChart.PlotArea.YAxis.AxisLabel.TextBlock.Text = "%";
radChart.PlotArea.YAxis.AxisLabel.TextBlock.Appearance.TextProperties.Color = System.Drawing.Color.Red;
radChart.PlotArea.YAxis.Appearance.Width = 3;
radChart.PlotArea.YAxis.Appearance.Color = System.Drawing.Color.Red;
// Add the series to the chart, chart to page.radChart.Series.Add(chartSeries);radChart.Series.Add(chartSeries2);this.Page.Controls.Add(radChart)

希望这有帮助..
