我目前正在使用下面显示的代码来格式化图表系列的点系列,但是我看不到任何更改点标签文本字体的方法。有人知道哪里可以访问点标签的字体属性吗?
'set the series point color dependent on value and retrieve the best & worst values
Dim bestval As Double = 0.0
Dim worstval As Double = 0.0
For Each pt As DataPoint In cht.Series("MonthPL").Points
'pt.IsValueShownAsLabel = True
pt.Label = "#VALY{C0}"
pt.LabelToolTip = "#AXISLABEL 's P/L is #VALY{C0}"
If pt.YValues(0) < 0 Then
If pt.YValues(0) < worstval Then worstval = pt.YValues(0)
pt.Color = Color.Red
pt.LabelForeColor = Color.Black
Else
If pt.YValues(0) > bestval Then bestval = pt.YValues(0)
pt.Color = Color.DarkGreen
pt.LabelForeColor = Color.GhostWhite
End If
Next
您应该在这里看到它
pt.Font
我在C#中使用的实际代码是
Chart1.Series[0].Points[0].Font
声明新字体,并使用它:
Font myFont = new Font(FontFamily.Generic.SansSerif, 14, FontStyle.Bold);
然后将数据点的font属性设置为:
pt.font = myFont;
添加为Font =“ Zurich BT,11pt,style = Bold”的系列标签
