teechart y=f(x)功能
vb下teechart y=f(x)功能用例程 不能绘制出曲线
有何错??
Private Sub UpdateChart()
'Force the recalculation function
TChart1.Series(0).FunctionType.BeginUpdate
TChart1.Series(0).FunctionType.EndUpdate
End Sub
Private Sub Command1_Click()
TChart1.ShowEditor 0
UpdateChart
End Sub
Private Sub Form_Load()
UpdateChart
End Sub
Private Sub TChart1_OnFunctionCalculate(ByVal SeriesIndex As Long, ByVal X As Double, Y As Double)
Y = Sin(X / 10)
End Sub
