[rrd-users] RRDs:graph / windoze - size graph still a problem

[gOdot]

When using win2k and RRDs:graph (not the .exe), the exemple below does not
work?
Does anyone tried to use RRDs from windoze?

>'-h526 -w2500',
GIF Size: 495x624


> '-h600 -w800',
GIF Size: 495x698

> '-h2500 -w10000',
GIF Size: 495x2598



here are part of the script :

my @options = ("-b", $START, "-s", $STEP,
 "DS:a:GAUGE:2000:U:U",
 "DS:b:GAUGE:200:U:U",
 "DS:c:GAUGE:200:U:U",
 "DS:d:GAUGE:200:U:U",
 "DS:e:DERIVE:200:U:U",
 "RRA:AVERAGE:0.5:1:5000",
 "RRA:AVERAGE:0.5:10:500");

RRDs::create $RRD1, @options;

<fill in>

 my ($graphret,$xs,$ys) = RRDs::graph $GIF, "--title", 'Test GRAPH',
    '--base', '1024',
           '-h1200 -w1600',  "tried ' and "
          "--vertical-label", 'Dummy Units', "--start", (-$RUNS*$STEP),
          "--end", $time,
	    "--interlace", "--imgformat","GIF",
	    "DEF:alpha=$RRD:a:AVERAGE",
          "DEF:beta=$RRD:b:AVERAGE",
          "DEF:gamma=$RRD:c:AVERAGE",
          "DEF:delta=$RRD:d:AVERAGE",
          "DEF:epsilon=$RRD:e:AVERAGE",
          "CDEF:calc=alpha,beta,+,2,/,100,*,102,/",
          "AREA:alpha#0022e9:Short",
          "GPRINT:calc:MAX:Max calc %1.2lf",
          "STACK:beta#00b871:Demo Text",
          "GPRINT:calc:AVERAGE:Average calc %1.2lf",
          "STACK:beta#0ad871:Demo Text 2",
          "LINE1:gamma#ff0000:Line 1",
          "LINE2:delta#888800:Line 2",
          "LINE3:calc#00ff44:Line 3",
          "LINE3:epsilon#000000:Line 4",
          "HRULE:1500#ff8800:Horizontal Line at 1500",
          "PRINT:alpha:AVERAGE:Average Alpha %1.2lf",
          "PRINT:alpha:MIN:Min Alpha %1.2lf",
          "PRINT:alpha:MAX:Max Alpha %1.2lf",
          "GPRINT:calc:MIN:Min calc %1.2lf";
          "VRULE:".($now-3600)."#008877:60 Minutes ago",
          "VRULE:".($now-7200)."#008877:120 Minutes ago";

Sure.

Creating a 10000 x 2500 graph:

/usr/bin/rrdtool graph /tmp/9-year.gif
 -w 10000 -h 2500
 COMMENT:"                   Avg       Max   Current\n"
 DEF:line72=/var/stats/run//21/21.31.rrd:ds0:AVERAGE
 CDEF:calcedline72=line72,100,*
 LINE1:calcedline72#0000FF:"1 minute"
 GPRINT:calcedline72:AVERAGE:"    %6.2lf %s"
 [.......]


10095x2637


No problem... (it only takes some time...)
