Visual Graph Getting Started - Use Line Vertexes

Now we make a sinusoid by a line and its vertexes.

Please follow these steps to make it.

1. Create a new file in Visual Graph IDE.

2. Draw a line and rect (basic elements in library group) in this document, right-click the rectangle to execute Add text command, and the paste the following text to rectangle:

Line1.PointCount=121
i=0
while i <= 120
Line1.X[i]=100+2*i
Line1.Y[i]=100+50*sin(i*3.1416/60)
i=i+1
wend
Line1.Refresh()


3. Click Program -> Command line menu item, input Execute (rect1.text) in the opened window and press <Enter>, the line will change to a sinusoid, like this:

Use Line Vertexes 1

4. Change rect1.text as below:

Line1.PointCount = 122
pi = 3.14159265359
i = 0
while i <= 120
Line1.X[i] = 100 + 50 * cos( i / 60 * pi )
Line1.Y[i] = 100 - 50 * sin( i / 60 * pi )
Line1.Bytes[i] = 6
Line1.X[i+1] = 100 + 60 * cos( i / 60 * pi )
Line1.Y[i+1] = 100 - 60 * sin( i / 60 * pi )
Line1.Bytes[i+1] = 2
i = i + 2
wend


input Execute (rect1.text) in the Command line window and press <Enter> again, the line will change as below:

Use Line Vertexes 2
