1. Ubuntu Server 10.10 Perl v5.10.1 for x86_64-linux-gnu-thread-multi RRDtool 1.4.3 RRDs module - I don't know if it has a separate version number but as far as I know it is a Perl only module. So my RRDs::graph commands are all in Perl. http://www.mrtg.org/rrdtool/prog/RRDs.en.html
My main concern is that the documentation here, http://www.mrtg.org/rrdtool/doc/rrdgraph.en.html does not specify how to use the 'Right Y Axis' option from within the RRDs Perl module. Most of the other options for example, show [-t|--title string] where -t is used within the Perl module and --title string is used from the command line, at least that's been my experience so far. As I said earlier, when I use the '--right-axis-label "Relative Humidity"' option with 'rrdtool graph' from the command line, I get the expected results. But I can not find any reference in any documentation for how to implement that same option from within the RRDs Perl module. The following code works from within Perl. How do I add the right-axis-label option to it? RRDs::graph "test.png", "-s 24hr", "-t Outdoor Temperature/Humidity: 24hr", "-h 120", "-w 830", "-a", "PNG", "-v deg C", "DEF:OutTemp=$rrd/Weather.rrd:OutTemp:AVERAGE", "DEF:OutHum=$rrd/Weather.rrd:OutHum:AVERAGE", "CDEF:nan=OutTemp,UN,INF,UNKN,IF", "AREA:nan#FF000070", "LINE1:OutTempM#32CD32:Temperature C", "GPRINT:OutTemp:MAX:Max\\: %5.1lf %s", "GPRINT:OutTemp:AVERAGE:Avg\\: %5.1lf %s", "GPRINT:OutTemp:MIN:Min\\: %5.1lf %s", "GPRINT:OutTemp:LAST:Last\\: %5.1lf %s\\l", "LINE1:OutHum#4169E1:Humidity % ", "GPRINT:OutHum:MAX:Max\\: %5.1lf %s", "GPRINT:OutHum:AVERAGE:Avg\\: %5.1lf %s", "GPRINT:OutHum:MIN:Min\\: %5.1lf %s", "GPRINT:OutHum:LAST:Last\\: %5.1lf %s\\l"; Matt On 11/1/2010 1:48 PM, Steve Shipway wrote: > In order to help you, it would be good if you could post -- > 1. which version of RRDTool you are using, and are you using it from command > line or from C, Perl, Python, etc etc > 2.
