[rrd-users] Unable to print date to the graph

[Sebastian John]

Hello,

thanks for the link. I found the solution. Is is not necessary to use
perl. But I have to write an other GPRINT link this:

GPRINT:tmax:"  max\: %10.2lf °C" 
GPRINT:tmax:"um %H\:%m Uhr\n":strftime

I have to add the ":strftime" on the GPRINT. 

Sebastian
