Switchtower for production?
Hello,
The company that I work for will be developing a large webbased survey
(for a government institution) somewhere in Q1/Q2 of 2006. I''m
investigating the technological possibilities and Rails is certainly a
candidate. The survey application will have to perform under very high
peak load, and the exact specifications of the hardware are not known
at this point. I''m assuming

Need some Gruff graphing help - custom dimensions?
I''ve been working with Gruff to do all my apps graphing and such etc. I
love it but I''m just having a hard time customizing the graphs, but this
is perhaps due to my inability to comprehend the online RDocs.
What I want to do is adjust the width / heights of my graphs or at the
VERY LEAST the heights. It seems that if you scale a graph anywhere
below 400-450px it is pretty

Ruby and charting
Hi-
I need to create simple charts on the fly - I had used JFreeChart in the
past with inJ2EE apps. Is there any equivalent here for Ruby. My
charting needs are simple: just line charts.
Also if anyone has done this, pls let me know how I should go about in
doing it.
Thanks

How can one use GRUFF with locomotive ( I guess there is a wider question here, also)
Hi:
I love Locomotive and use it exclusively for my rails projects. I''d
like to install GRUFF and give it a try (a graph image creation
package). I know I can do sudo gem install gruff from the command
line for normal ruby and rails. How do I make gems available to
Locomotive?

Gruff with PDF::Writer
Hello all
Has anyone managed to embed gruff graphs into a PDF document using
pdf::writer?
The easy way (as far as I can see) would be to just save the gruff graph
as a temporary file then read that file in pdf::writer. I was wondering
if anyone had managed to get them working together directly?

Have a quick Gruff Graphing question
I have some graphs and everything is working great, but I''d like to set
a minimum height so to speak on the vertical scale. Is there a method
to do that with Gruff? I''ve tried looking through the docs but can''t
seem to get it to work.
So for example, if the highest datapoint in my graph was say 500, is it
possible to have the minimum vertical scale on the left set

beginning a statistics application
Hi all,
I need to write an application that gets data from a database and plots
it on a graph.
I am familiar with java and know that I could do it with jfreechart -
however I am excited by RoR and would like to write the application with
RoR instead.
Is it possible to write it in RoR?

Gruff Charting Question
I am using Gruff to chart 2 sets of data and have run into a problem,
the numbers between the two sets are so far apart that the first set
appears as a mostly straight line at the top and the second a mostly

Is there a way to set the min/max vertical column values so that I can
