Default XL2002: XY Chart and Image Position...

Actually which object is on top and visibility is not relevant. You've got
me curious as to what you're doing with your lookup and how that relates to
a series point whose position is not easy to accurately control. If not
simple to explain I'd be pleased to look at what you're up to (my address is
disguised in the "reply to").

This macro is simplified in a number of respects but hopefully will work.
See comments about "ppp", for distribution to unknown users would require
API's. Uses brute force rather than calculating the point's position, hence
why I asked about speed. Speed could be improved by starting from top left
of the plot, though speed is better than I expected as should be fine to
"skip" pixels.

For testing I suggest make chartarea & Plot fill's invisible with the chart
"on top" so you can see what shape the point is over (you did say a single
series with single a point - right).

Sub SeriesPointOverShape()
Dim b As Boolean
Dim x As Long, y As Long, k As Long
Dim xx As Single, yy As Single
Dim elem As Long, arg1 As Long, arg2 As Long
Dim shp As Shape
Dim cht As Chart
Dim ppp As Single

' normally should get points per pixel with API's but
' but to simplify assume typical ppp for %90+ users at 0.75
ppp = 0.75

' oop pixels from top-leftt of chart until
' the series-1 is found with GetChartElement

Set cht = ActiveSheet.ChartObjects(1).Chart ' CHANGE to suit

xx = CLng(cht.Parent.Width / ppp) ' width in pixels
yy = CLng(cht.Parent.Height / ppp)

For k = 10 To 1 Step -2
'start by looping every 10th pixel to save time
For y = 1 To yy Step k
For x = 1 To xx Step k
Call cht.GetChartElement(x, y, elem, arg1, arg2)
If elem = xlSeries Then
'found the one & only series with single point, exit the loops
'(if need a particular series & point - check arg1 & arg2)
b = True
Exit For
End If
Next
If b Then Exit For
Next
If b Then Exit For
Next

If b Then
'convert chart pixel co-ord to worksheet point co-ord
xx = cht.Parent.Left + x * ppp
yy = cht.Parent.Top + y * ppp

b = False

'loop if/until our co-ord intersects a shape
For Each shp In ActiveSheet.Shapes
If shp.Name < cht.Parent.Name Then
With shp
If xx = .Left Then
If xx <= .Left + .Width Then
If yy = .Top Then
If yy <= .Top + .Height Then
b = True ' got it
Exit For
End If
End If
End If
End If
End With
End If
Next

If b Then MsgBox shp.Name
End If

End Sub

ha ha ha, thanks for the response Peter, and no, speed isn't important...
(ish)

Yes, shapes exist on the worksheet, and yes the chart order is 'on top'

Regarding visibility, it will probably be the opposite - the chart will be
visible and the shapes won't.

Once the name of the shape which the plot lies within is returned, I will
use a lookup to show a specific screen.

I'll be happy to mail the image to you on a personal e-mail if you think
it
will help.

Thanks again

Trevor

Presumably ChartArea's & Plot's Fill are invisible so you can see through
to
shapes and pictures, though that's not directly relevant.

Is speed important (say no!)

Hi All,

I have a simple XY graph, plotting 1 point only. This graph is in
front

of
an image made up of several shapes.

What I would like to do is return the name of the shape that the plot
sits
over.

Sounds simple, but where to start?

Any help appreciated.

Trevor
