I thought you could just add extra rrdtool graph commandline parameters to the hobbitgraph file for a graph section and hey presto it would use them. This seems to work for some and not for others. (eg -e and -A work)
It may be a more generic issue related to parameter assumptions within the code, but anyway, I added a some code to handle a couple of additional directives in hobbitgraph.cfg. (RSCALE, RFORMAT and RLABEL - in order to add a different scale to the right hand y axis.)
Should I look deeper into the code and see why --right-axis scale:shift, --right-axis-format and --right-axis-label seem to get ignored if I add them to hobbitgraph.cfg.
Or should I just use the code that I now have that uses my Hobbit specific directives.
Or am I missing something entirely altogether?
