I'm wanting to show BarChart Data and StackedBarChart data like PieData, I want to show the total value of each data section. any code examples?

B4X:
Sub BarChart_MouseMoved(Event As MouseEvent)
    Dim BC As BarChart = Sender

    Dim AxisCoord As XYCoord = BC.MouseToAxis(Event)
    Dim XAxis As CategoryAxis = BC.XAxis
    Dim YAxis As CategoryAxis = BC.YAxis
    Dim XValue As String = XAxis.GetValueForDisplay(AxisCoord.X)
    Dim YValue As Double = YAxis.GetValueForDisplay(AxisCoord.Y)
    lbDashboardInfo.Text = BC.Title & ", " & XValue & " = " & NumberFormat(YValue, 1, 0)
    
End Sub

I'm showing in lable: ChartName, Column, Legend = Value

Solved my issue..

B4X:
Sub BarChart_MouseMoved(Event As MouseEvent)
    Dim BC As BarChart = Sender   
    Dim AC As XYCoord = BC.MouseToData(Event)
    
    If AC = Null Then
        lbDashboardInfo.Text = QVdashText
    Else
        lbDashboardInfo.Text = BC.Title & ", " & AC.X & " = " & NumberFormat(AC.Y, 0, 2)
    End If   
End Sub
