Hi - I am creating bar and stacked bar charts in Gruff, but the problem I am having is that zero data is showing up as a thin bar. (It also seems to be that way in examples I have seen online where a zero value still shows as a thin bar or slice) It''s not a major issue to see a thin sliver on a plain bar chart, but on my stacked bar chart if I have more than one zero value in a

Hi I searched through the forum for the answer but couldn''t find any pointers. I have created an application using the gruff graphs. The problem is that these charts automatically calculates the y-axis scale. The requirement is to be in multiple of 100''s but internally it by default calculates something else which is not very convenient to read. Can someone please post some

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. 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

Has anyone achieved a stable deployment of Gruff with Rmagick on Windows? I''ve been playing around with this on Instant Rails and after installing the RMagick win 32 gem (local gem install as per instructions on web) and then Gruff on top of that.

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

Hello list, I''m having a problem getting Gruff working with Rails on a Windows XP box. I installed RMagick, then Gruff via the win32 gem, and it seemed to go OK. From irb, I can do the following - require ''rubygems'' ##### This returns ''false'', but seems to work OK - require ''gruff'' ####### Ditto - g = Gruff::Bar.new etc., and I get

This is off-topic because it''s installation specific, but I wondered if anyone could point me in the right direction. I installed ImageMagick and RMagick on my MacBook Pro using Darwin Ports and the normal gem install, respectively. I got the dreaded "bus error."

Unfortunately a number of our clients need extensive reporting capabilities. There are a number of Java 3d graphing libraries like the link below and PHP offerings out there. http://big.faceless.org/products/graph/index.jsp .Net has its new report viewer control for ASP.net 2.0 which allows you to create 2d/3d reports containing pie charts, line graphs etc. Whats cool about this control is

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?
