MS asp.net雷达图的丑陋绘制
MS asp.net雷达图的丑陋绘制
提问于 2011-02-17 22:44:08
我正在使用MS asp.net图表控件。我用雷达图绘制了一些值，但由于某些原因，X轴的线并不在中间相交。
我已经设置了LineWidth = 1，但是线条仍然需要2个像素，并且一些标记完全关闭，或者它可能是完全关闭的线条。也许我的文字也有点错，所以请看图片，希望你能理解我的问题。=)
生成图表的代码：
// Populate series data
Chart chart1 = new Chart();
chart1.ChartAreas.Add(new ChartArea("ChartArea1"));
chart1.Height = new Unit(380);
chart1.Width = new Unit(880);
//chart1.AntiAliasing = AntiAliasingStyles.Graphics;
//chart1.BackColor = Color.Transparent;
chart1.Customize += new EventHandler(Chart_Customize);
// Show as 3D
chart1.ChartAreas["ChartArea1"].Area3DStyle.Enable3D = false;
chart1.ChartAreas["ChartArea1"].AxisY.IntervalAutoMode
= IntervalAutoMode.FixedCount;
chart1.ChartAreas["ChartArea1"].AxisY.Interval = 10;
chart1.ChartAreas["ChartArea1"].AxisY.Maximum = 100;
chart1.ChartAreas["ChartArea1"].AxisY.IsReversed = true;
chart1.ChartAreas[0].AxisY.LineWidth = 1;
chart1.ChartAreas[0].AxisY.MajorGrid.LineColor = Color.Gray;
chart1.ChartAreas[0].AxisY.LineColor = Color.Gray;
chart1.ChartAreas[0].AxisY.MajorTickMark.Enabled = false;
List<string> names = new List<string>();
int namecounter = 1;
foreach (var p in Model.Participants)
{
if (SessionHandle.ShowNamesInDiagrams)
names.Add(p.Person.Name);
else
names.Add(namecounter.ToString());
namecounter++;
}
#region firstresult
if (SessionHandle.ShowFirstResult)
{
chart1.Series.Add(new Series("FirstResult"));
List<double> firstresult = new List<double>();
foreach (var p in Model.Participants)
{
var resultSummary = from r in Model.ResultSummary
where r.userID == p.ParentID && Model
.Modules
.Where(x => x.hasResult)
.ToList()
.Exists(x => x.ID == r.moduleID)
select r;
firstresult.Add(resultSummary.Sum(x => x.scorePercent)
/ Model.Modules.Where(x => x.hasResult).Count());
}
chart1.Series["FirstResult"].Points.DataBindXY(names, firstresult);
// Set radar chart type
chart1.Series["FirstResult"].ChartType = SeriesChartType.Radar;
// Set radar chart style (Area, Line or Marker)
chart1.Series["FirstResult"]["RadarDrawingStyle"] = "Marker";
chart1.Series["FirstResult"].Color = Color.DarkBlue;
chart1.Series["FirstResult"].MarkerImage
= Url.Content("~/Content/Images/firstresult.png");
// Set circular area drawing style (Circle or Polygon)
chart1.Series["FirstResult"]["AreaDrawingStyle"] = "Circle";
// Set labels style (Auto, Horizontal, Circular or Radial)
chart1.Series["FirstResult"]["CircularLabelsStyle"] = "Horizontal";
}

WPF坐标指的是像素的中心，而不是角，所以尝试在所有坐标上加上0.5。要说明这一点，请考虑以下xaml：
<Canvas>
<Line X1="50" Y1="50" X2="100" Y2="50" Stroke="Black" StrokeThickness="1" />
<Line X1="50" Y1="50" X2="50" Y2="100" Stroke="Black" StrokeThickness="1" />
<Line X1="50" Y1="50" X2="100" Y2="100" Stroke="Black" StrokeThickness="1" />
</Canvas>在这里，它被正常渲染，然后对每个坐标应用0.5像素的偏移：
