Unneeded line after drawing graph on picture box

[Mas Juliza Alias]

Hi,
I have a problem with the graph I drawn on a picture box for quite a while. I have two curves, elevation-storage and elevation-area curves which need to be drawn on a single graph. I managed to draw it nicely if the curves are drawn separately, but somehow when the curves are merged together (by merging the same codes as they are drawn separately) there is an unneeded line appears diagonally from min value to the max value of x,y. How can I eliminated it? Attached is the project I coded so far. Your help is highly appreciated. Thank You.

You are using the command = picture1.line -(...) !
The string "-" is for the function=

Step= Optional.Keyword specifying that the starting point coordinates are relative to the CURRENT graphics position given by the CurrentX and CurrentY properties.

The last thing you have done BEFORE to start drawing the graphic line is setting the X line for "Area".
So the last coordinates are in the right-upper corner.
The first point of the data = (0,0).
With the command .line -(0,0) you are drawing a line from the upper-right corner to 0,0.

So before you start drawing the curves, you have to reset the CurrentX and CurrentY.

Sub AreaGraph()
Dim j As Integer
   'area curve
   With Form1.Picture1
      .CurrentX = 0
      .CurrentY = 0
   End With
   With Form1.MSFlexGrid1
      For j = 1 To .Rows - 1
         Form1.Picture1.Line -(.TextMatrix(j, 1), .TextMatrix(j, 0)), vbGreen
      Next
   End With
End Sub

Also attached is your code with some modifications in calling the subroutines.
