Question:
How can I plot the functions y=x+2; y=X^2; y=x^3 in an E3Chart?
Solution:
To do so, use Pen’s AddPoint method, via scripts, to add points to a chart.
Examples:
** To plot a Y = X + 2 chart **
Dim X
Dim Y
Dim aux
X = 1
Y = 1
Screen.Item(“E3Chart1”).Pens.Item(“Pen1”).Clear()
Screen.Item(“E3Chart1”).Pens.Item(“Pen1”).Connect()
For aux=1 to 10
X = X + 0.11
Y = X + 2
Screen.Item(“E3Chart1”).Pens.Item(“Pen1”).AddPoint X, Y
Next
Screen.Item(“E3Chart1”).FitAll([FitStyle])
** To plot a Y = X ^ 2 chart**
Dim X
Dim Y
Dim aux
X = -1
Y = 1
Screen.Item(“E3Chart1”).Pens.Item(“Pen1”).Clear()
Screen.Item(“E3Chart1”).Pens.Item(“Pen1”).Connect()
For aux=1 to 18
X = X + 0.11
Y = X ^ 2
Screen.Item(“E3Chart1”).Pens.Item(“Pen1”).AddPoint X, Y
Next
Screen.Item(“E3Chart1”).FitAll([FitStyle])
** To plot a Y = X ^ 3 chart **
Dim X
Dim Y
Dim aux
X = -1
Y = 1
Screen.Item(“E3Chart1”).Pens.Item(“Pen1”).Clear()
Screen.Item(“E3Chart1”).Pens.Item(“Pen1”).Connect()
For aux=1 to 18
X = X + 0.11
Y = X ^ 3
Screen.Item(“E3Chart1”).Pens.Item(“Pen1”).AddPoint X, Y
Next
Screen.Item(“E3Chart1”).FitAll([FitStyle])
