Hi
I am having a difficult time getting Excel automation to work
correctly.specifically, i've become hung up on creating multiple
charts.
I am able to make a basic XY Scatter plot with the following code:
==
$Sheet-Range(A:A,D:D,K:K,R:R)-Select;
$Chart = $Book-Charts-Add;
$Chart-{ChartType} = xlXYScatter;
$Chart-{Name}=Temperature;
==
and it correctly charts D, K, and R column data (temperatures) versus
the A column data (time)
but if i want to make another (separate) chart plotting E, L, and S
column data (conductivity) versus the A column data (time), and i
follow the above code with a similar block:
==
$Sheet-Range(A:A,E:E,L:L,S:S)-Select;
$Chart = $Book-Charts-Add;
$Chart-{ChartType} = xlXYScatter;
$Chart-{Name}=Conductivity;
==
it fails, with the following error message
OLE exception from Microsoft Excel:
Unable to get the Select property of the Range class
Win32::OLE(0.1704) error 0x800a03ec
in METHOD/PROPERTYGET Select at hexconvert.pl line 322
(where line 322 is in the second block:
$Sheet-Range(A:A,E:E,L:L,S:S)-Select; )
Can someone point out where I'm going wrong?
Also, If I could just find a reference of Excel OLE properties and
methods I think I could hack my way through it. But I haven't been
able to find anything like that.
does anyone know if such a list exists?
thanks,
rob
I know I've faced this in the past after converting recorded macro
verbatim. I can't easily test a
solution based on your example because it is not 'complete and
working'... ;-) A couple of things
that might help:
A snippet of mine that sets a range as source for a chart:
$range = A25: . $endCol . 26;
$Excel-ActiveSheet-ChartObjects('Chart 1')-Activate();
$Excel-ActiveChart-SetSourceData({Source = $pSheet-Range($range),
PlotBy = 2});
As I recall, it is possible to skip the ...Activate line and reference
the ChartObjects(...) instead
of ActiveChart in the line following it.
The VBA editor itself has the Object Browser documentation built-in -
right-click in editor pane.
Often, pasting the error right into Google yields valuable pointers or
solutions.
Even though I use perl almost exclusively over VBA I have had excellent
method advice from contributors
over on microsoft.public.excel.misc.
