我試圖在餅圖中爆炸或爆炸爆炸點。
但是,當我爆炸一個點時,它'知道'它會爆炸,但它不會在圖表上出現。質譜圖控制不爆炸餅點
Protected Sub Chart2_Click(sender As Object, e As ImageMapEventArgs) Handles Chart2.Click
Dim pointIndex As Int32 = Int32.Parse(e.PostBackValue)
If pointIndex >= 0 & pointIndex < Series1.Points.Count Then
If Series1.Points(pointIndex)("Exploded") = "True" Then
Series1.Points(pointIndex)("Exploded") = "False"
Series1.Points(pointIndex).MapAreaAttributes += "onclick=""alert('Test explode alert');"""
Else
Series1.Points(pointIndex)("Exploded") = "True"
End If
End If
End Sub
我確實得到了「測試爆炸警報」,但此時餅圖點並沒有在視覺上爆炸。
刪除Series1.Points(pointIndex)("Exploded") = "False"
使點看起來爆炸,但不會爆炸/不爆炸它們。
我該如何爆炸或爆炸爆炸點?
