[rrd-users] Y-axis label is sometimes 1.0 instead of 1

[Petteri Matilainen]

Hello all,

I'm graphing temperature (gauge). I have placed Y labels with the -y 
0.5:2 parameter which gives me major grid lines every degree and minor 
grid lines ever half a degree. Labels are at every degree so they should 
always be exactly an even degree. I also use alt-y-grid.

But sometimes if I have eg. an y-range of -3 to +4 degrees the Y label 
is 0.0, 1.0, 2.0 and so on. I have also another graph (same rrdgraph 
script) for inside temperature and the values are fine: 25, 26 and so 
on. Why does rrdtool put 1.0, 2.0 and so on when the values (range?) is 
small enough? Can this be forced somehow to always display an integer 
instead of float? Thanks! Oh, and I'm using rrdtool 1.4.7.

regards,

Petteri
