Nalina has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks,

I am using MS Excel application to draw graph and then exporting the graph to an html page.

Part of my script which is generating Graph is as follows.

my $Range = $Sheet->Range("B1:D$row"); my $Chart = $Sheet->ChartObjects; my $AgeChartContainer = $Chart->Add(200,30,500,300); my $AgeChart = $AgeChartContainer->Chart; $AgeChart->{ChartType} = $Constant->{xlLineMarkers}; $AgeChart->Location($Constant->{xlLocationAsObject}, $Sheet->{ +Name}); $AgeChart = $Excel->ActiveChart; $AgeChart->{ChartType} = xlLineMarkers; $AgeChart->SetSourceData({Source => $Range, PlotBy => xlColumns} +); $AgeChart->SeriesCollection(1)->{XValues}= "=Sheet1!R1C1:R"."$ro +w"."C1"; $AgeChart->{HasTitle} = 1; $AgeChart->{HasLegend} = 1; $AgeChart->Legend->{Position} = xlLegendPositionTop; $AgeChart->SeriesCollection(1)->{Name} = "max"; $AgeChart->SeriesCollection(2)->{Name} = "min"; $AgeChart->SeriesCollection(3)->{Name} = "avg"; $AgeChart->SeriesCollection(2)->{MarkerStyle} = xlDiamond; $AgeChart->SeriesCollection(3)->{MarkerStyle} = xlDiamond; $AgeChart->SeriesCollection(3)->{MarkerForegroundColorIndex} = + 10; $AgeChart->SeriesCollection(3)->{MarkerBackgroundColorIndex} = + 10; $AgeChart->SeriesCollection(3)->Border->{ColorIndex} = 10; $AgeChart->ChartTitle->{Text} = "Total Memory Usage - 192.168.21 +8.135(MAPLE) $Date"; $AgeChart->Axes(xlCategory, xlPrimary)->{HasTitle} = 1; $AgeChart->Axes(xlCategory, xlPrimary)->AxisTitle->{Text} = "Dat +e\nMax = $Max Min = $Min Avg = $Avg "; $AgeChart->Axes(xlValue, xlPrimary)->{HasMajorGridlines} = 1; $AgeChart->Axes(xlCategory, xlPrimary)->{HasMajorGridlines} = 1; $AgeChart->Axes(xlValue, xlPrimary)->MajorGridlines->Border->{Co +lorIndex} = 15; $AgeChart->Axes(xlCategory, xlPrimary)->MajorGridlines->Border-> +{ColorIndex} = 15; $AgeChart->Axes(xlValue, xlPrimary)->{HasTitle} = 1; $AgeChart->Axes(xlValue, xlPrimary)->AxisTitle->{Text} = "Total +Memory Used(%)"; $AgeChart->PlotArea->Border->{ColorIndex} = 16; $AgeChart->PlotArea->Interior->{ColorIndex} = 2; $Book->SaveAs('C:\\Graph.xls'); $Book->Close({SaveChanges=>0});
I want to reduce the X-axis value font

I tried
$AgeChart->TickLabels->Font->{Size}=6;
but didn't work. How do I do it?

Regards

    I could be wrong, but I think it is
    $AgeChart->Axes(xlCategory, xlPrimary)->TickLabels->Font->{Size} = 6;
      Thanks for ur reply.

      I have one more problem. I want the series name to be vissible at the last data point.

      I tried
      AgeChart->SeriesCollection(1)->Points(30)->{ShowSeriesName} = True;
      but got an error saying
      Win32::OLE(0.1701) error 0x80020003: "Member not found" in PROPERTYPUT "ShowSeriesName" at graph.pl line 88
      Thanks & Regards

    If the desired endpoint is a webpage GD::Graph is an easy and fast way to generate png graphs. You can use GD::Graph::Map to map hotpoints and you can get the GD binary as a ppm from ActiveState. Using GD::Grpah is way simpler as well as being a lot faster.

      Hi,

      Thanks for the reply.

      I could not install GD::Graph & GD::Graph::Map on windows machine.

      Can I install it using ppm. If so please give me the url to do it.

      Thanks & Regards

      Nalina

        Unlike GD itself (which need compilation) these modules are pure perl so will install without any issues on Win32. See A Guide to Installing Modules, get nmake, get the tarballs from CPAN, perl Makefile.PL && nmake && nmake test && nmake install. There is more to life that what comes as a PPM. This is some of it.....

        cheers
