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?

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.

I''m just getting started with GD2 and have successfully made a few dynamic PNGs. I need to make some fairly detailed line graphs on the fly and I know that GD2 is capable of what I want but I strongly suspect I''m reinventing the wheel badly. Are there gems or other projects that help creating complex charts? I''ve used GDChart in the distant past but I

Hi, As a long time Java/J2EE exponent I wanted to give Rails a fair crack of the whip and after we evaluated it for several weeks I have to say I like it. The installation process for the base system/framework is straightforward on the two platforms we''ve tried (Windows and Mac OS X). However, the charting components available, relying on ImageMagick or GraphicsMagick seem less clear

Hello everyone, I''m looking to produce some graphs broadly like the ones shown here: http://www.dotnetcharting.com/gallery/List.aspx?gal=6 No prize for guessing what type of app it is... This particular graphing library is .NET-specific, but as you can see the results it produces are really nice. More than likely, they''re several notches above what I''ll be able to

Hi, for those with experience of Gruff module: suppose I want to send image from server straight to the browser (as example on gruff web site): send_data(g.to_blob, :disposition => ''inline'', :type => ''image/png'', :filename => "gruff.png") the server seems sending this binary data ok, but I am having

Hi, I am working on a project where I need to generate a chart (a bit like a pie chart, but very customised) and insert this into a PDF document. Does anybody have any advice on ruby libraries (or other techniques) for doing this? Open to suggestions? The resulting PDF will be designed for printing and so ideally should be vector throughout (or any raster images 300dpi). I was thinking of some

I read the 13th recipe in the book "Rails Recipes" from Chad Fowler. I install with gem the gruff-library (gem install gruff). After the installation, I download the "rmagick-win32-1.13.0_IM-6.2.9-3.zip" file and install it on my win32-machine. It was successfully! So, I create a controller with script/generate. In a method, which I wrote after the creation, I''ll make

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/. --~--~---------~--~----~------------~-------~--~----~

Hi all, This might be OT. Wondering what are available charting solutions that work well with Ruby on Rails. I''ve seen reference to a few but they all seem to rely on integration with a program written in another language (requiring a seperate process per chart), Perl''s GD module for instance. Is there a 100% Ruby charting library that is freely available? Thanks, Dave

Hi, I''m fairly new to Rails and am moving from PHP. I am looking for a way to generate generate image plots on a Webpage. I have looked at SVG::Graph, but it doesn''t look nearly as flexible or functional as jpGraph, which I use in PHP (http://www.aditus.nu/jpgraph/). I also generate some more complex graphs using matplotlib via Python

Hi, I''m developing a budget planner for myself and do have a table for recurring expenses, as well as a transaction table for my bank account CSV file uploads.
