[rrd-users] HRULE and VRULE legends

[Petteri Matilainen]

Hi!

I'm using rrdtool 1.4.7 on debian linux. I'm graphing temperatures with 
GAUGE. Everything is working fine except recently I found out that my 
HRULE legends did not print.

After awhile I found this option, -F (--force-rules-legend). So this 
allowed the legends to print again as I had set the upper limit of the 
graph to 24 and I got around 28-30. But, I don't know if this is 
expected behaviour that even though the HRULE lines and main graph line 
print because of autoscale the legends don't. The help says:

[-F|--force-rules-legend]

Force the generation of HRULE and VRULE legends even if those HRULE or 
VRULE will not be drawn because out of graph boundaries.

So according to this the legend is not printed if the lines are not 
printed. But for me the lines are printed but the legend is not. So all 
it takes is that -l or -u definitions that are out of range. The graph 
may still print okay.

Please excuse me if this have been addressed in 1.4.8, I have not 
checked the changelog.

regards,
