GD::Graph New Window

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

Hi,

Perl: ActiveState 5.6.1, OS Windows 2000, IIS 5.0

I'm having troulble outputting a chart to a new window. If I call the below sample code from a form or an image tag within the same window the pie image is successfully returned to the browser. However, if I call the code with javascript's,

window.open("pie.pl?$passstring", "window name", "width=650,height=650
+")
[download]

the output prompts me to open or save the file. I guess it doesn't know where to return the output. Any ideas on how I can tell it to output to the current window or why it's trying to output as a file?

use GD::Graph::pie(350,350);
@data=([@name], [@value]);
$graph = new GD::Graph::pie;
$graph->set(
title           => "$title",
label           => 'Label Goes Here',
axislabelclr    => 'black',
'3d'            => 1,
start_angle     => 90,
suppress_angle => 5) or warn $graph->error;
$graph->set_title_font(GD::Font->MediumBold);
$graph->set_value_font(GD::Font->Small);
$format=$graph->export_format;
print header("image/$format");
binmode STDOUT;
print $graph->plot(\@data)->$format() or die $graph->error;

Thanks.

Mitch

I am confused. You start by saying that you are having trouble outputting the chart to a new window but then later say that you are trying to output to the current window If I look at you javascript I believe that this will open a new browser window. So if this is what you are tryin to do ... have you tried ...html (anchor tag) code follows `<A TARGET="_blank" HREF=""pie.pl?$passstring"">Display Pie Chart</A>` [download] This will open the output of your pie.pl script in a NEW window.. ----- Of all the things I've lost in my life, its my mind I miss the most.

The problem is if I call the pl with the open window function it doesn't work. It only works if a pl is called with an image tag to display in the already open window. I think it might be a matter of using a "Get". I'm going to try opening a window containing a form with hidden fields and auto submit. This way the pl will be called with a "Post" instead.
