删除(折叠) LineSeries 中的数据点? [英] Removing (collapsing) DataPoints in a LineSeries?
问题描述
我想从 Silverlight 图表中的 LineSeries 中删除数据点标记.我在网上找到的唯一方法是将 VisibilityProperty 设置为 Collapse.
I'd like to remove the datapoint markers from a LineSeries in my Silverlight chart. The only way i found on the web is to set the VisibilityProperty to Collapse.
//不适用于当前的 SL 工具包版本var collapseDataPointSetter = new Setter(Control.VisibilityProperty, Visibility.Collapsed);
//not working in the current SL toolkit release var collapseDataPointSetter = new Setter(Control.VisibilityProperty, Visibility.Collapsed);
但这不适用于当前版本的 SL 工具包.如何在当前版本中删除或隐藏数据点标记?
But this isn't working for the current release of the SL toolkit. How can i remove or hide DataPoint Markers in the current release?
推荐答案
pantarhei,
使用以下图表样式(带有参考模板)隐藏数据点.我已经包含了 LineSeries 和 AreaSeries 的样式.
Use the following chart styles (with referenced templates) to hide the data points. I have included styles for both the LineSeries and the AreaSeries.
祝你好运,吉姆
