标签:style   color   使用   width   数据   os   

1、调用wcf 获取信息

private void svc_GetSingleChartDataCompleted(object sender, GetSingleChartDataCompletedEventArgs e)
{
ObservableCollection<ListItem> lBaseOilBar = e.Result;
CreateChart(this.gridVisifire, lBaseOilBar);
}

2、构造图表 ,根据解析xml获得的ListItem 画图

public void CreateChart(Grid oGrid, ObservableCollection<ListItem> lBaseOilBar)
{
foreach (ListItem li in lBaseOilBar)

#endregion

chart.AxesX.Add(axisX);
#endregion
#region Y 坐标轴
