How to Make XY Graph In VB

[hellokitty]

Hi,

I have the following x and y coordinates.
x y
== ==
2 4
5 7
11 4
9 20


How to draw the x-y graphs with a straight line start from origin (0,0) connected to each coordinate (x,y). Most of the tutorial that i know don;t show details of the steps and not similar at all.

Thanks guys

Assuming you already have it scaled properly, it's pretty simple.

picturebox.line (x1,y1)-(x2,y2)

consider x1 and y1 the coordinates of the first point, and x2,y2 as the second point, connecting the two with a straight line.

I'll do the scale, the basic lines for the graph, and the first two lines. go ahead do the last two yourself, see how simple it is.

Private Sub Command1_Click()
picOutput.Scale (-2, 30)-(30, -3) 'Scales the graph
picOutput.Line (-2, 0)-(30, 0) 'Draws x-axis
picOutput.Line (0, -3)-(0, 30) 'Draws y-axis
picOutput.line (0,0)-(2,4) ' First line
picOutput.Line (2, 4)-(5, 7) 'second line
End Sub
