当然可以，

要显示在X轴上提示

Chart1.Series["SeriesName"].LabelToolTip = "#VALX [#VALY]";

和在Y轴

Chart1.Series["SeriesName"].ToolTip = "#VALX [#VALY]";

VALX - > X轴值
VALY - > Y轴值
有很多也喜欢
＃百分
#AVG等等等等

VALX --> X-axis value VALY --> Y-axis value there are many as well like "#PERCENT" "#AVG" etc etc

您可以把电气特性的提示，只要你喜欢。

you can put anyother tooltip as you like.
