Devexpress Chart series 点击时获取SeriesPoint的值
在这里做个备注：
public partial class XtraForm2 : DevExpress.XtraEditors.XtraForm
{
private LabelControl _labelControl;
private int xpoint;
private int yponit;
public XtraForm2()
{
InitializeComponent();
_labelControl = new LabelControl();
chartControl1.Controls.Add(_labelControl);
chartControl1.MouseClick += new MouseEventHandler(ChartControl1MouseClick);
}
void ChartControl1MouseClick(object sender, MouseEventArgs e)
{
xpoint = e.X;
yponit = e.Y;
}
private void ChartControl1ObjectSelected(object sender, DevExpress.XtraCharts.HotTrackEventArgs e)
{
if (e.AdditionalObject == null) return;
SeriesPoint point = (SeriesPoint)e.AdditionalObject;
string ms = string.Format("Value{0},argument:{1}", point.ValuesSerializable, point.Argument);
_labelControl.Text = string.Empty;
_labelControl.Location = new Point(xpoint, yponit);
_labelControl.Text = "值:" + point.ValuesSerializable;
}
}
