[rrd-users] Junk characters instead of graph

[Chitman Kaur]

 Hi All
I am trying to write a perl script which queries the RRD and displays the graph on the standard output... i.e. my webpage which called this perl file...
But no image is displayed.... only junk characters....

Something like below...

1sJh rŒ‘Æ#¡1A† ƒ„ANZíÅYoÞýCq$9h !`“V{qÖ›wÿÁPÉò‚ŒANcÌ”ÆH 4! ƒ”ÆÌ)‘ÆŒ Æ„`L0&À` rÒ*±Ôi  Æ„`LÁ¤4f#™SBc`Ó˜`L0F ƒ1&Œ1Áä¤Õ^œõæÝ0G’‚ˆ”!Œ!  rÒj/Îzóî?Š#Y^ÿ10HiŒ™Æ#„Æ„¤ AJ[1] Á˜B0Ƙ`€FÊ C0ÈI«4ÆRc¤)™ÆLiÌ4Є` rJc¨4ÆÐi  Æ„`L0&  rÒj/Îzóî?Š#IA$„@BCä¤Õ^œõæÝ0G²¼ 
My code is...

my(@args) = (        "--start","$start",
        "--end","$end",
        "--imgformat","GIF",
        "--height","150",
        "--width","540",
        "--color","BACK#FFE2C6",
        "--color","MGRID#000000",
        "--color","SHADEA#999999",
        "--color","SHADEB#000000",
        "--color","GRID#999999",
        "-t $cust  $host  $ifindex $ran",
        "-v $t1",
        @DEF1,
        @DRAW

        );

#print "Content-type: image/gif\r\n\r\n";

RRDs::graph( '-', @args);
my $ERR=RRDs::error;
print "$ERR" if $ERR;

I tried putting Content type to image but its still giving junk characters...

Any ideas...

Regards

Chitman
