Hi everybody, I''m using scruffy to create some graphs, and would like to integrate them into a regular view (i.e. show them in an <img> tag). However, I get errors when using img_tag, or the image doesn''t load if I try saving the graph to disk and then loading them in html. Generating the graph and linking to it works, however then I only have the graph open in a new

Hi Folks, since I have scruffy up and running now I´d like to integrate the desired images on some of my rails views. But neither scruffy nor rails docs say something about this and I cannot find examples or help on this. So I hope somebody on this forum has experiences in integrating scruffy images on rails views. I find out how to go the easy and obvious way: Export image to a file and then

Hi- Trying to do a stacked bar chart, but nothing is rendering when I add more then 1 bar: This works: graph = Scruffy::Graph.new(:title => "My Chart") graph.add :stacked do |stack| stack.add(:bar, ''Stack1'', [10,10]) end This doesn''t: graph = Scruffy::Graph.new(:title => "My Chart") graph.add :stacked

Hello, I would like to get a window handle from another app outside of wxRuby and convert it into a wxRuby Window handle so that I can use it as the parent Window for several wxRuby child windows. Basically I want to use the FRAME_FLOAT_ON_PARENT window style so that my wxRuby windows become associated with the outside app kind of like toolbars, e.g., they don''t show up in the

Whereabouts would I want to put a Ruby file that extends a Rails class? Say, adding a method to ActiveRecord::Base or something along those lines. I''ve read that those classes go in /lib, but my application doesn''t seem to see the changes I''ve made. Obviously I''m missing something... Any suggestions would be appreciated! -Brasten

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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I would like to extract an image BLOB from my database and display it alongside some other information on my ''edit'' page.

I''m running a Rails application with WEBrick server. We are displaying an Image from the server to the Client (Browser). First time on the browser everything looks fine, upon clicking the link, it contacts the server and displays in IE brwoser the image that was stored on the server.

Hello I have been trying a number of security/login generators recently. My favourite so far is the Acts_as_authenticated. I like the fact that it is only billed as a starting point and doesn''t try to do everything. I would like to add security roles to it, so that some of my controller actions can only be used by an admin role. Has anybody implemented this using

I''m trying to display a generated .png plot via send_data(), but it results in a server error "invalid byte sequence in US-ASCII" error. I''m pretty sure this means that I need to specify the encoding somewhere, but I haven''t been able to figure out where or how to do so. Some particulars: I''m running gnuplot through a pipe to generate a plot in .png

Hi, I am a newby in rails...and i have read that scruffy is a great tool to create/display images.

I don''t believe that Rails has support for the inline editing of datetime objects or dropdown combo boxes. Does anyone have a helper function or two that would allow me to do such a thing? -- Posted via http://www.ruby-forum.com/.

Hi -- I have imagemagick and rmagick installed so that I can produce images from code to a file. Can anyone direct me to where I can find guidance on how to have those images included on a web page (e.g., <img src="my_dynamically_generated_image") instead of having them sent to a file? Thanks for any input. ... doug --~--~---------~--~----~------------~-------~--~----~ You

Hi- I have been using Scruffy for a couple days and it''s worked out really well. I am stuck though getting a bar chart to work with a single line. Here''s what I am doing: general chart stuff..graph.new...etc ... my_graph.add(:bar, ''GOAL'', [250,350]) my_graph.add(:bar, ''ACTUAL'', [150,200]) This works, but what I was is a SINGLE Bar with one

Short question: is there way to tell EM to actually send data after send_data call? I''m building a file transferring app. I send Mashal.dump''ed metadata first, and then - the file contents (chunked). I found a silly bug: receive_data() gets marshalled metadata and the first chunk of the file in a single variable. Like that: c1.send_data("meta")
