in reply to Excel Graph *issue*


After quite a few tries (and backfires...), I've come till this, thanks to a number of "supporters".
I know this code can be made shorter, and multiple lines of code can be singled out, and all that. All my focus is on the Excel Graph, and nothing else matters right now.

use strict; use Win32::OLE; use Win32::OLE::Const 'Microsoft Excel'; # Start Excel and create new workbook with a single sheet use Win32::OLE qw(in valof with); use Win32::OLE::Const 'Microsoft Excel'; use Win32::OLE::NLS qw(:DEFAULT :LANG :SUBLANG); my (@Names); $Win32::OLE::Warn = 3; push @Names, ['loy', 13]; push @Names, ['toy', 12]; push @Names, ['mccoy', 05]; push @Names, ['roy', 47]; push @Names, ['loy', 24]; push @Names, ['toy', 05]; push @Names, ['joy', 24]; print "Start Excel\n"; my $Excel = Win32::OLE->new('Excel.Application', 'Quit'); $Excel->{Visible} = 1; $Excel->{SheetsInNewWorkbook} = 1; my $Book = $Excel->Workbooks->Add; my $Sheet = $Book->Worksheets(1); $Sheet->{Name} = 'DepOne'; my $Range = $Sheet->Range("A1:B1"); $Range->{Value} = [qw(Name Hours)]; $Range->Font->{Bold} = 1; print "Add data\n"; $Range = $Sheet->Range(sprintf "A2:B%d", 2+$#Names); $Range->{Value} = \@Names; print "Create chart\n"; $Sheet->Range("A:B")->Select; my $Chart = $Book->Charts->Add; $Chart->Chart->ChartWizard({Source =>$Sheet->Cells(15)}); $Chart->{ChartType} = xlColumn; $Chart->Location(xlLocationAsObject, $Sheet->{Name}); # Excel bug: old $Chart has become invalid now! $Chart = $Excel->ActiveChart; # Add title, remove legend with($Chart, HasLegend => 0, HasTitle => 1); $Chart->ChartTitle->Characters->{Text} = "Department One"; # Fat candles with only 5% gaps $Chart->ChartGroups(1)->{GapWidth} = 5; sub RGB { my ($red,$green,$blue) = @_; return $red | ($green<<8) | ($blue<<16); } # White background with a solid border $Chart->PlotArea->Border->{LineStyle} = xlContinuous; $Chart->PlotArea->Border->{Color} = RGB(0,0,0); $Chart->PlotArea->Interior->{Color} = RGB(255,255,255); # Add 1 hour moving average of the Close series my $MovAvg = $Chart->SeriesCollection(4)->Trendlines ->Add({Type => xlMovingAvg, Period => 4}); $MovAvg->Border->{Color} = RGB(255,0,0); $Book->SaveAs('somefile.xls'); $Book->Close;
Items Pending:

1. Fill each column bar in a chart with a particular color
2. Put this chart in the same sheet along with the data in it

All thoughts are welcome
