Winform Chart控件绘制阴影区域

先来看看效果

公司电力项目需要绘制这种工业图表，之前同事用Series绘制的 有点麻烦 需要计算起始点位置，后来我发现Chart控件本来就提供了这种阴影属性，简单方便

直接上代码

private void InitChart()
        {
            ChartArea chartArea2 = new ChartArea();

            chartArea2.AxisX.Minimum = 10;
            chartArea2.AxisX.Maximum = 100;
            chartArea2.AxisX.Interval = 10;
            chartArea2.AxisX.IsStartedFromZero = true;
            chartArea2.AxisX.Title = "主 X 轴";
            chartArea2.AxisX.Enabled = AxisEnabled.True;
            chartArea2.AxisX.TitleAlignment = StringAlignment.Near;
            chartArea2.AxisX.MajorGrid.LineColor = Color.Brown;
            chartArea2.AxisX.MajorGrid.LineDashStyle = ChartDashStyle.Solid;

            chartArea2.AxisY.Minimum = 10;
            chartArea2.AxisY.Maximum = 100;
            chartArea2.AxisY.Interval = 10;
            chartArea2.AxisY.IsStartedFromZero = false;
            chartArea2.AxisY.Title = "主 Y 轴";
            chartArea2.AxisX.Enabled = AxisEnabled.True;

            chartArea2.Name = "chartArea2";

            Series m1 = new Series();
            m1.Points.AddXY(0, 100);
            m1.Points.AddXY(85, 100);
            m1.ChartType = SeriesChartType.Area;
            m1.Color = Color.Red;
            m1.BackHatchStyle = ChartHatchStyle.DarkDownwardDiagonal;

            Series m2 = new Series();
            m2.Points.AddXY(10, 30);
            m2.Points.AddXY(35, 55);
            m2.Points.AddXY(65, 55);
            m2.Points.AddXY(85, 65);
            m2.ChartType = SeriesChartType.Line;
            m2.Color = Color.Blue;
            m2.BorderWidth = 2; 

            Series m5 = new Series();
            m5.Points.AddXY(10, 30);
            m5.Points.AddXY(35, 55);
            m5.Points.AddXY(65, 55);
            m5.Points.AddXY(85, 65);
            m5.ChartType = SeriesChartType.Area;
            m5.Color = Color.Purple;
            m5.BackHatchStyle = ChartHatchStyle.DarkDownwardDiagonal;

            Series m6 = new Series();
            m6.Points.AddXY(10, 20);
            m6.Points.AddXY(35, 45);
            m6.Points.AddXY(65, 45);
            m6.Points.AddXY(85, 55);
            m6.ChartType = SeriesChartType.Line;
            m6.Color = Color.Blue;
            m6.BorderWidth = 2; 

            Series m3 = new Series();
            m3.Points.AddXY(10, 20);
            m3.Points.AddXY(35, 45);
            m3.Points.AddXY(65, 45);
            m3.Points.AddXY(85, 55);
            m3.ChartType = SeriesChartType.Area;
            m3.Color = Color.Green;
            m3.BackHatchStyle = ChartHatchStyle.DarkDownwardDiagonal;

            this.chart1.Series.Add(m1);
            this.chart1.Series.Add(m2);
            this.chart1.Series.Add(m5);
            this.chart1.Series.Add(m6);
            this.chart1.Series.Add(m3);

            this.chart1.ChartAreas.Add(chartArea2);
        }
