Thanks heaps Rocky
I'll give it a go

Darren:

I had to make a rather complicated bar graph for an app years ago and what I
decided to do, instead of drawing the lines was to start with the maximum
length line and adjust the length in the Detail_Format event.  You could do
the same by making all the lines in the report, set them to Visible No, and
visiblizing the ones you want. That's the easy way.

You can also draw stuff like this using .Line:

    ' Draw up-pointing triangle for txt box
    rptBigOne.DrawWidth = 10
    rptBigOne.Line (txtParticipantAverage.Left - 30,
txtParticipantAverage.Top + 40)- _
        (txtParticipantAverage.Left, txtParticipantAverage.Top + 100),
QBColor(0)
    rptBigOne.Line (txtParticipantAverage.Left, txtParticipantAverage.Top +
100)- _
        (txtParticipantAverage.Left + 30, txtParticipantAverage.Top + 40),
QBColor(0)
    rptBigOne.Line (txtParticipantAverage.Left - 30,
txtParticipantAverage.Top + 40)- _
        (txtParticipantAverage.Left + 30, txtParticipantAverage.Top + 40),
QBColor(0)
    rptBigOne.DrawWidth = 1

    ' Draw down-pointing triangle for txt box
    rptBigOne.DrawWidth = 10
    rptBigOne.Line (txtOrganizationAverage.Left, txtOrganizationAverage.Top 
+ 120)- _
        (txtOrganizationAverage.Left + 30, txtOrganizationAverage.Top + 60),
QBColor(0)
    rptBigOne.Line (txtOrganizationAverage.Left + 60,
txtOrganizationAverage.Top + 120)- _
        (txtOrganizationAverage.Left + 30, txtOrganizationAverage.Top + 60),
QBColor(0)
    rptBigOne.Line (txtOrganizationAverage.Left, txtOrganizationAverage.Top 
+ 120)- _
        (txtOrganizationAverage.Left + 60, txtOrganizationAverage.Top +
120), QBColor(0)
    rptBigOne.DrawWidth = 1
End If

where rptBigOne is set to the name of the report.

You can use CurrentX and CurrentY properties of the report which is a lot of
fun and print something at the current location:

    rptBigOne.CurrentY = Text109.Top + (intJ - 1) * 142
    rptBigOne.CurrentX = intLeft - 75 + intK * 1.5 / intPointMax * 1440 If
Nz(gintGraph2(ItemNumber, intJ, intK)) <> 0 Then
    rptBigOne.Print Str(gintGraph2(ItemNumber, intJ, intK)) Else
    rptBigOne.CurrentX = rptBigOne.CurrentX + 60
    rptBigOne.CurrentY = rptBigOne.CurrentY - 60
    rptBigOne.Print "."
'     MsgBox "X=" & rptBigOne.CurrentX & " " & "Y=" & rptBigOne.CurrentY & "

" & "gintgraph2=" & gintgraph2(ItemNumber, intJ, intK) End If

But I think making the lines you want to show visible in the Format event is
probably the easiest way I know of.

HTH
