本文介绍了一种通过ColumnSeries图表展示设备特征码成功比率的方法。具体实现包括：清除旧数据、填充新数据到Successrates集合中，并将这些数据绑定到ColumnSeries上进行展示。此外，还实现了点击柱状图项时的事件响应，用于加载详细信息。

      public void T_ConditionSuccess(Object sender, GetConditionCodeRateCompletedEventArgs e)
        {
if (e.Error == null)
            {
                Successrates.Clear();

                ConditionCodeChart.Axes.Clear();
                ConditionCodeChart.Series.Clear();
foreach (MDXValue mdv in e.Result)
                {
                    ConditionRatioBind src = new ConditionRatioBind();
                    src.Title = mdv.Title;
                    src.Value = mdv.MValue * 100;
                    Successrates.Add(src);
                }
                ConditionCodeChart.Axes.Clear();
                ConditionCodeChart.Series.Clear();


                ColumnSeries cls = new ColumnSeries();
                cls.ItemsSource = null;
                cls.ItemsSource = Successrates;
                cls.IndependentValueBinding = new Binding("Title");
                cls.DependentValueBinding = new Binding("Value");
                cls.AnimationSequence = AnimationSequence.FirstToLast;
                cls.IsSelectionEnabled = true;
                cls.SelectionChanged += new SelectionChangedEventHandler(cs_SelectionChanged);
                cls.Title = "设备比例";
                ConditionCodeChart.Series.Add(cls);
//ConditionCodeChart.Title = "特征码设备比例";
                Title += "特征码设备比例";
                ConditionCodeChart.Title = Title;
            }
else
            {
                Alerts.ShowError(e.Error.ToString());
            }
        }

(ConditionCodeChart.Series[0] as ColumnSeries).SelectedItem = null;

这句话代表取消选择。

        void cs_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            ColumnSeries cs = (ColumnSeries)sender;
if ((ConditionCodeChart.Series[0] as ColumnSeries).SelectedItem!=null)
            {
string str = cs.SelectedItem.ToString();
string name = ((ConditionRatioBind)cs.SelectedItem).Title;
string param = string.Empty;
if (name.Contains("语音"))
                {
                    param = "语音";
                }
if (name.Contains("短信"))
                {
                    param = "短信";
                }
if (name.Contains("GPRS"))
                {
                    param = "GPRS";
                }

                ConditionDetailInfos tpu = new ConditionDetailInfos();
                tpu.ConditionDetailInfosLoad(null, sAreaName, sDateTime, param);
                tpu.Show();
               (ConditionCodeChart.Series[0] as ColumnSeries).SelectedItem = null;
            }
        }
