<pre><code>Chart1.Series[i]["PieLabelStyle"] = "Disabled";

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

Found the answer here: <a href="http://social.msdn.microsoft.com/Forums/en-US/MSWinWebChart/thread/32ccd993-5f43-47a3-bcbc-e772a13a87fe" rel="noreferrer">http://social.msdn.microsoft.com/Forums/en-US/MSWinWebChart/thread/32ccd993-5f43-47a3-bcbc-e772a13a87fe</a>

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.

<pre><code>for (var i = 0; i &lt; chart.Series.Count; i++) 
 for (var j = 0; j &lt; chart.Series[i].Points.Count; j++)
 chart.Series[i].Points[j]["PieLabelStyle"] = "Disabled";
</code></pre>

blocks|key|1346753|text|更改图表自定义属性也可以做到这一点，并且不需要编码|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1346754|<asp:Series+Name="Series1"+ChartType="Pie"+CustomProperties="PieLabelStyle=Disabled">|code-block|syntax|javascript|1346755|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

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

<pre><code>&lt;asp:Series Name="Series1" ChartType="Pie" CustomProperties="PieLabelStyle=Disabled"&gt;
</code></pre>

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.

Anyone know what property I can use in code behind?

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

Hide labels in pie charts (MS Chart for .Net)

​​我似乎找不到控制饼图中标签可见性的属性。我需要关闭标签，因为图例中提供了相关信息。有人知道我可以在后台代码中使用什么属性吗？我尝试将系列标签设置为nothing Chart1.Series[i].Label = string.Empty;，但标签似乎无论如何都会出现。
