隐藏饼图中的标签（.Net的MS图表）

I can't seem to find the property that controls visibility of labels in pie charts. I need to turn the labels off as the information is available in the legend.

我似乎无法找到控制饼图中标签可见性的属性。我需要关闭标签，因为图例中的信息可用。

Anyone know what property I can use in code behind?

任何人都知道我可以在代码背后使用什么属性？

I tried setting the series labels to nothing Chart1.Series[i].Label = string.Empty; but the labels seem to show up anyway.

我尝试将系列标签设置为无Chart1.Series [i] .Label = string.Empty;但无论如何，标签似乎都出现了。

6 个解决方案

#1

Chart1.Series[i]["PieLabelStyle"] = "Disabled";

works too, and doesn't need to be set for each datapoint.

也适用，不需要为每个数据点设置。

It turns out there is an obscure DataPointCustomProperty called PieLabelStyle that governs label visibility in pie charts. Worse still, the property must be set on each data point.

事实证明，有一个名为PieLabelStyle的模糊DataPointCustomProperty控制饼图中的标签可见性。更糟糕的是，必须在每个数据点上设置属性。

for (var i = 0; i < chart.Series.Count; i++) 
    for (var j = 0; j < chart.Series[i].Points.Count; j++)
        chart.Series[i].Points[j]["PieLabelStyle"] = "Disabled";

Changing chart custom properties will do the trick as well and no coding is needed

更改图表自定义属性也可以解决问题，无需编码

<asp:Series Name="Series1" ChartType="Pie" CustomProperties="PieLabelStyle=Disabled">

May be this website solve your problem

可能是这个网站解决了你的问题

protected void Page_Load(object sender, EventArgs e) {
// Insert code to create basic pie chart // See my blog post entitled "Pie Charts in ASP.NET" for full source code

protected void Page_Load（object sender，EventArgs e）{//插入代码以创建基本饼图//查看我的博客文章“ASP.NET中的饼图”获取完整源代码

     // Set pie labels to be outside the pie chart
     this.Chart2.Series[0]["PieLabelStyle"] = "Outside";

     // Set border width so that labels are shown on the outside
     this.Chart2.Series[0].BorderWidth = 1;
     this.Chart2.Series[0].BorderColor = System.Drawing.Color.FromArgb(26, 59, 105);

     // Add a legend to the chart and dock it to the bottom-center
     this.Chart2.Legends.Add("Legend1");
     this.Chart2.Legends[0].Enabled = true;
     this.Chart2.Legends[0].Docking = Docking.Bottom;
     this.Chart2.Legends[0].Alignment = System.Drawing.StringAlignment.Center;

     // Set the legend to display pie chart values as percentages
     // Again, the P2 indicates a precision of 2 decimals
     this.Chart2.Series[0].LegendText = "#PERCENT{P2}";

     // By sorting the data points, they show up in proper ascending order in the legend
     this.Chart2.DataManipulator.Sort(PointSortOrder.Descending, Chart2.Series[0]);
 }

...and Ben's answer in VB.NET format:

...和Ben的VB.NET格式答案：

Chart1.Series(0)("PieLabelStyle") = "Disabled"

works fine for setting whole series

适用于设置整个系列

#6

objChart.ChartAreas[0].AxisY.LabelStyle.Enabled = false;

#1

Chart1.Series[i]["PieLabelStyle"] = "Disabled";
