主题：移动开发-自定义函数衔接

3楼是你函数的代码？如果是，不可能报错。如果不是，贴出你函数的代码。

执行这个代码，不可能报错

Dim Chart As ChartBuilder = Functions.Execute("task")

实例发上来测试

Dim Chart As New ChartBuilder
Dim Series As WinForm.ChartSeries
Chart.PrintWidth = 140
Chart.PrintHeight = 100
Chart.VisualEffect = True
For n As Integer = 0 To 1
    Series = Chart.SeriesList.Add()
    Series.Length = 10
    For i As Integer = 0 To 9
        Series.X(i) = i
        Series.Y(i) = i + n * 2 + Rand.Next(5)
    Next
Next
chart.HeaderText = "可以利用Foxtable的ChartBuilder动态生成图表"
Return Chart
