Question

vb画坐标系，怎么让坐标系可以随着函数图像的大小自动调整？

Answer 1

Private Sub Form_Load()
Form2.AutoRedraw = True
End Sub

Private Sub Form_Resize()
Form2.Cls
Form2.Scale (-20000, 20000)-(20000, -20000)
Form2.DrawWidth = 3
Form2.Line (-15000, 0)-(15000, 0), vbBlue
Form2.ForeColor = vbBlue
Form2.Print "x"
Form2.DrawWidth = 2
Form2.DrawWidth = 1.2
Form2.Line (0, -15000)-(0, 15000)
Form2.ForeColor = vbBlue
Form2.Print "y"
Form2.CurrentX = 0
Form2.CurrentY = 0
Form2.Print "0"
End Sub

Answer 2

这个还是最好设置坐标的范围比较好
因为自动调整的话

刷新比较慢
效果不好
