I agree with Michael and Francisco.  RRDTOOL is the way to go for time based
graph such as that which you describe.  I was recently faced with a similar
graphing need and RRDTOOL worked exceptionally.

There is a small learning curve that is quickly overcome once you get into
the time based graphing mindset rather than the excel data driven graphing
mindset.  For your typical .csv conversion to graph, RRDTOOL is pretty much

I can send you my database creation, scripted updates and scripted graph
generating commands offlist if you would like.

Subject: Graphing Tool


I'm looking for a command-line utility to run on a Linux 
platform that can generate some line or bar graphs based on 
basic data such as number of junk e-mail messages rejected, 
etc.  I do use MRTG to monitor network devices in 5 minute 
intervals, but I'm interested in automatically generating 
some graphs based on daily totals instead of constant gauge 
readings.  Perhaps I can adjust interval settings for MRTG 
(or RRDTOOL) to accomplish this.

I don't need anything to generate the data, I can script 
that, but I'm interested in what others are using to generate 
graphs like this.  For example I may want to have a graph 
showing total junk messages rejected over the past seven days 
with one bar (or line point) for each day.  This is generally 
a job for a spreadsheet (i.e. Excel), but I want to automate 
this so I can view the output on a web interface.

What tools are people using to generate such graphs?
