如需将IF函数的图形化显示，可以通过
excel的
VBA编辑器来实现。首先，在
excel中打开“数据”选项卡，并点击“数据工具”按钮，选择“创建表”并点击“确定”。接着，在
VBA编辑器中输入以下代码：Sub IfChart()Dim x As DoubleDim y As DoubleDim i As IntegerFor i = 1 To 10x = iIf x > 20 Theny = x * 0.1Elsey = x * 0.2End IfNextReDim x(1 To 10, 1 To 1)x(1, 1) = xFor i = 1 To 9x(i + 1, 1) = x(i, 1) * 0.1NextFor i = 1 To 9x(i + 1, 2) = x(i, 1) * 0.2NextSheet1.Shapes.AddLine x(1, 1), x(10, 1), x(1, 2), x(10, 2).Left, x(1, 2).WidthSheet1.Shapes.AddLine x(1, 1), x(10, 1).Bottom, x(1, 2), x(10, 2).Bottom, x(1, 2).Height, x(10, 2).HeightSheet1.Shapes.AddLine x(1, 1), x(10, 1).Left, x(1, 2), x(10, 2).Left, x(1, 2).Width / 2, x(10, 2).Width / 2Sheet1.Shapes.AddLine x(1, 1).Bottom, x(10, 1).Bottom, x(1, 2).Bottom, x(10, 2).Bottom, x(1, 2).Height / 2, x(10, 2).Height / 2Sheet1.Shapes.AddLine x(1, 1).Right, x(10, 1).Right, x(1, 2).Right, x(10, 2).Right, x(1, 2).Width / 2, x(10, 2).Width / 2Sheet1.Shapes.AddText "x", 100, 100, "Arial", 12Sheet1.Shapes.AddText "y", 100, 120, "Arial", 12Sheet1.Shapes.AddText "y*: x > 20", 100, 140, "Arial", 12Sheet1.Shapes.AddText "y*: x
