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
