Hi list, I'm having difficulty setting a graph TITLE font size using the RRDTool Perl bindings (RRDs::graph).
When used in a shell with `rrdtool graph`, both "-n TITLE:7:" and "--font TITLE:7:" work as expected and give the desired result. However, both options when passed to RRDs::graph produce an error. "-n TITLE:7:" results in: Error: RRDs::graph failed, invalid text property format "--font TITLE:7:" results in: Error: RRDs::graph failed, unknown option '--font TITLE:7:' A Google search for both errors hasn't turned up anything useful, the closest I got was a posting in the Cacti forums ( http://forums.cacti.net/about28174.html) that suggested upgrading RRDTool. I am using RRDTool version 1.4.7 on CentOS 5.4 For completeness, I have included below both a dump of the array passed to RRDs::graph which produces the failure, as well as the result of the same arguments passed to `rrdtool graph` Any advice much appreciated. Thanks in advance, Darren @graph_args = ( '/home/mrtg/png/custom/brbraholid-usg-1_aux0-1376582178.png', '-s 1375134000', '-e 1375146000', '-u', 5000000, '--font TITLE:7:', '-t "brbraholid-usg-1_aux0 - 2013-07-29 13:40:00 to 2013-07-29 17:00:00 BOT"', '--lazy', '-c', 'FONT#000000', '-c', 'MGRID#000000', '-c', 'FRAME#000000', '-g', '-l', '0', '-c', 'BACK#f5f5f5', '-c', 'ARROW#000000', '-b', 1000, '-w', 400, '-h', 100, 'DEF:in0=/home/mrtg/logs/brbraholid-usg-1_aux0.rrd:ds0:AVERAGE', 'CDEF:in=in0,8,*', 'DEF:maxin0=/home/mrtg/logs/brbraholid-usg-1_aux0.rrd:ds0:MAX', 'CDEF:maxin=maxin0,8,*', 'DEF:out0=/home/mrtg/logs/brbraholid-usg-1_aux0.rrd:ds1:AVERAGE', 'CDEF:out=out0,8,*', 'DEF:maxout0=/home/mrtg/logs/brbraholid-usg-1_aux0.rrd:ds1:MAX', 'CDEF:maxout=maxout0,8,*', '-v', 'Bits per second', 'AREA:in#00cc00:In', 'LINE2:out#0000ff:Out', 'PRINT:out:MAX:%.1lf', 'PRINT:in:MAX:%.1lf', 'PRINT:out:AVERAGE:%.1lf', 'PRINT:in:AVERAGE:%.1lf', 'PRINT:out:LAST:%.1lf', 'PRINT:in:LAST:%.1lf', 'HRULE:5000000#cc0000' ); # rrdtool graph /home/mrtg/png/custom/brbraholid-usg-1_aux0-1376582307.png "-s 1375134000" "-e 1375146000" -u 5000000 --font TITLE:7: -t "brbraholid-usg-1_aux0 - 2013-07-29 13:40:00 to 2013-07-29 17:00:00 BOT" --lazy -c FONT#000000 -c MGRID#000000 -c FRAME#000000 -g -l 0 -c BACK#f5f5f5 -c ARROW#000000 -b 1000 -w 400 -h 100 DEF:in0=/home/mrtg/logs/brbraholid-usg-1_aux0.rrd:ds0:AVERAGE CDEF:in=in0,8,* DEF:maxin0=/home/mrtg/logs/brbraholid-usg-1_aux0.rrd:ds0:MAX CDEF:maxin=maxin0,8,* DEF:out0=/home/mrtg/logs/brbraholid-usg-1_aux0.rrd:ds1:AVERAGE CDEF:out=out0,8,* DEF:maxout0=/home/mrtg/logs/brbraholid-usg-1_aux0.rrd:ds1:MAX CDEF:maxout=maxout0,8,* -v "Bits per second" AREA:in#00cc00:In LINE2:out#0000ff:Out PRINT:out:MAX:%.1lf PRINT:in:MAX:%.1lf PRINT:out:AVERAGE:%.1lf PRINT:in:AVERAGE:%.1lf PRINT:out:LAST:%.1lf PRINT:in:LAST:%.1lf HRULE:5000000#cc0000 497x152 1509394.8 4679144.1 870588.4 3460818.0 630603.4 3686902.0
