similar to: gruff send_data

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

Hi, I am using "gruff" lib for creating the graphs. I have got the success to create the graph, but my problem is I don''t want to store it, I want that they should be displyed on the browser it self. I have tried this:- " send_data(g.to_blob, :disposition => ''inline'', :type => ''image/png'', :filename =>

Dears, Got a controller witch do a send_data for displaying a chart. like : send_data(g.to_blob, :filename => "any.png", :type => ''image/png'', :disposition=> ''inline'') I actually do a <img src="http://myhost:3000/stats/make_graph" /> Is there any way more clean to do that ? At minima don''t hardcode the beginning

Hi all, I hope somebody can help me out here, since the issue has been killing me for the last three days. Here is the issue: It seems that gruff kills rails/webrick whenever it''s used on win32. I installed gruff per instructions and it seems to be working. The sample controller generates a nice grpah with send_data and all. The issue started once I try to use any other

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

I have installed Gruff and am trying to get an example to work i found at http://tomcopeland.blogs.com/juniordeveloper/2006/02/charts_and_grap.html. I have the following code in the controller: # Send a graph to the browser def crumpetchartaction days = 5 g = Gruff::Line.new(500) g.title = "Crumpets over the past #{days} days" g.theme_keynote crumpets_to_date = []

I am using rmagick to convert files stored as a tiff to either pdf or jpg for display to the user. A snippet of test code from the controller follows. It works OK. ( it does need a sanitizer ) require RMagick def pdf @sdoc = Sdoc.find(params[:id]) @fname = ''/var/www/images/'' + @sdoc.fname @nf = Magick::ImageList.new(@fname)

Hi All, I am new to both Ruby and Rails, so please be patient with me. I am currently working on a view for a controller and I have used the following excerpt: <td><%= link_to_image "b_edit", :action => ''edit'', :id => part_prefix %></td> The image is being displayed and the link is working. However, the formatting of image rendered

Hi, I am looking for the best solution to resize images to fit within a certain area. The images will only be made smaller if they will not fit within a fixed size area. It is important to maintain the same proportions. This ImageMagick extension looks promising: http://vantulder.net/rails/magick/ However, I believe it may be overkill for just resizing images sometimes. I have also seen a

I know that Zed has made mention of the fact that using RMagick with mongrel and rails is a bad thing. I''m currently using FlexImage (which in turn uses RMagick) on my application and really haven''t had too many problems. We get a restart for memory usage every 8-10 hours on one mongrel of twelve running, but I''m not sure if that''s an RMagick issue. Either way,

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. I did a test controller method that rendered the fruit pie chart as per the examples on the gruff site. This worked. However, when I refreshed

In http://dev.rubyonrails.org/changeset/5358 and the new alternative deprecation method, deprecate :link_image_to => :link_to_image should probably use the message version, as both link_image_to and link_to_image should be deprecated (according to the comments at least): deprecate :link_image_to => "Use link_to(image_tag()) instead"

Hello, I am having a strange problem with Gruff not always displaying the graph on the page. On some pages, the graph is displayed fine. On others, however, I just get the number relating to the id of the requested item - in my case, report. Does anyone know how to solve this problem? I have the following in my controller: def create_graph g = Gruff::Line.new(290) g.title =

Greetings all, This is the first release of the SuperImage plugin. The idea is you upload images to the database, and then pull them out at any size you want. Combine this with caching and it will stay light and fast.

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.

I am trying to dynamically set the compression or quality of an image when displaying it. I have seen in the RMagick documentation how to set the quality only when writing the file to disk. How can I set the quality dynamically or set the compression? The method "image.quality=" does not exist and "image.compression_type=" is not in the documentation. I have tried

Hello Railslist, I''m trying to get Gruff running on OSX Tiger (intel) with edge Rails. I''ve installed ImageMagick, Rmagick, FreeType and all their dependencies, or so I believe. (I''ve compiled them from source mostly, following a recent tutorial for Rails and ImageMagick on Intel Macs) While following the sample on the Gruff downloadpage (the one with the fruit), Rails
