我找不到正确格式的提示

foreach (RootObject o in myRootObjects)
{ 
    seriesTemperatur.Points.AddXY(DateTime.Parse(o.datum), o.temp);               
    seriesPressure.Points.AddXY(DateTime.Parse(o.datum),  o.pressure);
}

__

private void chart2_GetToolTipText(object sender, ToolTipEventArgs e)
{
    switch (e.HitTestResult.ChartElementType)
    {
        case ChartElementType.DataPoint:
            var dataPoint = e.HitTestResult.Series.Points[e.HitTestResult.PointIndex];
            e.Text = string.Format("Temperatur C:\t{1}\nData: {0}", dataPoint.XValue, dataPoint.YValues[0]);
            break;
    }
}

作为dataPoint.XValue中的日期，我得到

dataPoint {{X=43459,6591203704, Y=3,19}}, 

但是我需要X =“ 2018-11-22 HH：mm”。

var dataPoint = e.HitTestResult.Series.Points[e.HitTestResult.PointIndex];
e.Text = string.Format("Temperatur C:\t{1}\nData: {0}", dataPoint.XValue, dataPoint.YValues[0]);

我得到：

dataPoint {{X = 43459,6591203704，Y = 3,19}} System.Windows.Forms.DataVisualization.Charting.DataPoint

AxisLabel为空

    AxisLabel   ""  string
