我想创建area range chart如下所示link http://jsfiddle.net/D4w7G/3
我想使用数据循环将数据添加到范围。应该是什么类型ranges创建图表？
请建议。提前致谢。这是 JSFiddle 代码：

这是一个生成图表图形的示例，就像链接图像中的图表图形一样。
注意：在创建了一些测试数据后，我计算了一个具有透明颜色的虚拟系列，这将使整个数据堆叠起来，以便“中性”系列的中位数很好地位于一条水平线上。
int numPoints = 30; // create some test data
List<int> neutralData = new List<int>();
List<int> negativeData = new List<int>();
List<int> positiveData = new List<int>();
List<int> dummyData = new List<int>();
for (int i = 0; i < numPoints; i++)
{
// the real data series, using a Random R:
positiveData.Add(R.Next(i + 22));
neutralData .Add(R.Next(i + 33));
negativeData.Add(R.Next(i + 44));
// calculate the transparent bottom series:
dummyData.Add( - neutralData[i] / 2 - negativeData[i]);
}
// set up the Chart:
chart1.ChartAreas.Add("StackedArea"); // if necessary
Series s0 = chart1.Series.Add(" ");
Series s1 = chart1.Series.Add("negative");
Series s2 = chart1.Series.Add("neutral");
Series s3 = chart1.Series.Add("positive");
foreach (Series s in chart1.Series) s.ChartType = SeriesChartType.StackedArea;
s0.Color = Color.Transparent;
s1.Color = Color.FromArgb(200, Color.Red);
s2.Color = Color.FromArgb(200, Color.LightSlateGray);
s3.Color = Color.FromArgb(200, Color.Green)
// now add the data points:
for (int i = 0; i < numPoints; i++)
{
s0.Points.AddXY(i, dummyData[i]);
s1.Points.AddXY(i, negativeData[i] );
s2.Points.AddXY(i, neutralData [i]);
s3.Points.AddXY(i, positiveData[i]);
}
如果您想显示与示例中的工具提示类似的工具提示，您可以将其添加到 AddXY 循环中：
int a2 = dummyData[i] + negativeData[i];
int a3 = a2 + neutralData[i];
int a4 = a3 + positiveData[i];
string tt = string.Format( "Data Point {0}\r\nPositive: {1} - {2}\r\n"
+ "Neutral: {2} - {3}\r\nNegative: {3} - {4}", i, a4, a3, a2, dummyData[i]);
s1.Points[i].ToolTip = tt;
s2.Points[i].ToolTip = tt;
s3.Points[i].ToolTip = tt;
