Gruff gives font-related error
Hello Railslist,
I''m trying to get Gruff running on OSX Tiger (intel) with edge Rails.

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?

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

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

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
straight line at the bottom.
Is there a way to set the min/max vertical column values so that I can
squeeze the data closer together so that there is more ''movement''? If

pie chart as per the examples on the gruff site. This worked. However, when
