Dropped packets on negative axis

Tested on: 1.4.21

This minor change allows the dropped packets to be seen in the negative y-axis instead:

1. You must have applied the "link quality addition" modification first (obviously?)
2. Edit /usr/local/bin/makegraphs alter the procedure updatelqgraph as below:
   

   sub updatelqgraph { my $period = $_[0]; RRDs::graph ("$graphs/lq-$period.png", "--start", "-1$period", "-aPNG", "-i", "-z", "--alt-y-grid", "-w 600", "-h 100", "-u 70", "-t $tr{'lq'} ($tr{'graph per'} $tr{$period})", "--lazy", "--color", "SHADEA#EAE9EE", "--color", "SHADEB#EAE9EE", "--color", "BACK#EAE9EE", "-v pkt loss -% / ms", "DEF:roundtrip=$rrdlog/lq.rrd:roundtrip:AVERAGE", "DEF:loss=$rrdlog/lq.rrd:loss:AVERAGE", "CDEF:roundavg=roundtrip,PREV(roundtrip),+,1.05,/", "CDEF:lossavg=loss,PREV(loss),+,2,/", "CDEF:lossd=lossavg,-1,*", "CDEF:loss10=loss,-10,*", "CDEF:r0=roundtrip,20,MIN", "CDEF:r1=roundtrip,50,MIN", "CDEF:r2=roundtrip,80,MIN", "CDEF:r3=roundtrip,100,MIN", "AREA:roundtrip#EE7000:>100 ms", "AREA:r3#D88E1B:80-100 ms", "AREA:r2#B9B63F:50-80 ms", "AREA:r1#99E064:20-50 ms", "AREA:r0#80FF80:<20 ms", "AREA:lossd#FFAA33:Ave Packet loss %", "AREA:loss10#FF0000:Packet loss %\\j", "LINE1:roundtrip#707070:", "GPRINT:roundtrip:MAX:$tr{'maximal'} $tr{'linkqrt'}\\:%3.2lf ms", "GPRINT:roundtrip:AVERAGE:$tr{'average'} $tr{'linkqrt'}\\:%3.2lf ms", "GPRINT:roundtrip:LAST:$tr{'current'} $tr{'linkqrt'}\\:%3.2lf ms\\j", "GPRINT:loss:MAX:$tr{'maximal'} $tr{'linkqls'}\\:%3.2lf%%", "GPRINT:loss:AVERAGE:$tr{'average'} $tr{'linkqls'}\\:%3.2lf%%", "GPRINT:loss:LAST:$tr{'current'} $tr{'linkqls'}\\:%3.2lf%%\\j" ); $ERROR = RRDs::error; print "Error in RRD::graph for Link Quality: $ERROR\n" if $ERROR; }
