similar to: Gruff - using customized scale

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

Hi all, I''ve been playing around with Gruff, love the pie chart functionality! I''m having one problem though with lots of items in the legend. It seems Gruff doesn''t handle wrapping of the legend?

Hello, I used gruff library to display some of bar charts. It works fine but Gruff API documentation does not explain much like java api. So if I wanted to try some features like spacing between two bars, 3-D graph. It may be features available in Gruff library, but it is not well documented, I guess. Helpful resources would be appreciated. Thank You. Dakshesh

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? RJ -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~

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.

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.
