[rrd-users] Some advice.

[Winton Davies]

Hi,

   I've been experimenting with RRD as a way of graphing Price data. I 
don't need averages or anything like that. Basically I need RRD to 
simply store and graph daily data.


  Day 1 $70
  Day 2 $80
  Day 3 $75

The Graph would show Day 1 = 70, Day 2 = 80, and Day 3 = 75
 
I'm hoping that RRD will just efficiently store my data and give me graphs :)

  Cheers,
    Winton



This is a script I created:
rrdtool create new1.rrd --start 960830287 --step 86400 
DS:a:ABSOLUTE:86400:U:U RRA:MAX:1:1:9
rrdtool update new1.rrd 961089487:79
rrdtool update new1.rrd 961348687:73
rrdtool update new1.rrd 961607887:83
rrdtool update new1.rrd 961867087:88
rrdtool update new1.rrd 962126287:73
rrdtool update new1.rrd 962385487:70
rrdtool update new1.rrd 962644688:69
rrdtool update new1.rrd 962903888:78
rrdtool update new1.rrd 963163088:57
rrdtool fetch new1.rrd MAX --resolution 86400 --start 960830287 --end 963163088


Which results in the following list...
