[rrd-users] Re: Trouble with RRDs::graph

Yesterday you sent me mail regarding [rrd-users] Trouble with RRDs::graph:

*> Hi!

hi M@,

would be able to produce a bit of code which first sets up the RRD, then
updates it with data and then creates the graph and segfaults ... 

best would be a shell script ... perl will work as well ...

thanks very much
tobi

PS Please use rrdtool-1.0.9 for your tests ... The code above would not be
allowed in 1.0.9 ... you would be required to use %5.2lf or something like
it ... 


cheers
