i have a problem with rrdcgi:

i want to draw a graph of 4 lines, where 2 lines come from 1 rrd and 2 from another.
ther graph works.
i print the average, max and last-values on the bottom of the graph.

so far, so good, but:

when using rrdtool to draw the graph and the stats, all works fine

when using rrdcgi, the stats of the last 2 lines are the stats of the first...!

in rrdtool:
           max   avg   last
link1 in:    1     2      3
link1 out:   4     5      6
link2 in:    7     8      9
link2 out:  10    11     12

in rrdcgi:
           max   avg   last
link1 in:    1     2      3
link1 out:   4     5      6
link2 in:    1     2      3
link2 out:   4     5      6

perl example for rrdtool:
# create lines and legends (also summary info)
  push @args, "LINE2:inutil1#00cc00: Link 1  in";
  push @args, "GPRINT:inutil1:MAX:MAX %3.1lf%%";
  push @args, "GPRINT:inutil1:AVERAGE:AVG %3.1lf%%";
  push @args, "GPRINT:inutil1:LAST:NOW %3.1lf%%\\l";
  push @args, "LINE2:oututil1#0000cc: Link 1 out";
  push @args, "GPRINT:oututil1:MAX:MAX %3.1lf%%";
  push @args, "GPRINT:oututil1:AVERAGE:AVG %3.1lf%%";
  push @args, "GPRINT:oututil1:LAST:NOW %3.1lf%%\\l";
  push @args, "LINE2:inutil2#00ff00: Link 2  in";
  push @args, "GPRINT:inutil2:MAX:MAX %3.1lf%%";
  push @args, "GPRINT:inutil2:AVERAGE:AVG %3.1lf%%";
  push @args, "GPRINT:inutil2:LAST:NOW %3.1lf%%\\l";
  push @args, "LINE2:oututil2#0000ff: Link 2 out";
  push @args, "GPRINT:oututil2:MAX:MAX %3.1lf%%";
  push @args, "GPRINT:oututil2:AVERAGE:AVG %3.1lf%%";
  push @args, "GPRINT:oututil2:LAST:NOW %3.1lf%%\\l";

example rrd-cgi:
	GPRINT:inutil1:MAX:"MAX %3.1lf%%"
	GPRINT:inutil1:AVERAGE:"AVG %3.1lf%%"
	GPRINT:inutil1:LAST:"NOW %3.1lf%%"
	GPRINT:oututil1:MAX:"MAX %3.1lf%%"
	GPRINT:oututil1:AVERAGE:"AVG %3.1lf%%"
	GPRINT:oututil1:LAST:"NOW %3.1lf%%"
	GPRINT:inutil2:MAX:"MAX %3.1lf%%"
	GPRINT:inutil2:AVERAGE:"AVG %3.1lf%%"
	GPRINT:inutil2:LAST:"NOW %3.1lf%%"
	GPRINT:oututil2:MAX:"MAX %3.1lf%%"
	GPRINT:oututil2:AVERAGE:"AVG %3.1lf%%"
	GPRINT:oututil2:LAST:"NOW %3.1lf%%"
