Hi, I have a controller that uses gruff to create a chart. I would like to be able to return this image back to the view without having to dump the image to disk first. Does anyone have sample code for the controller and view to handle such a problem ? Thank you all !! ---

Create a specific action to generate the image and send it with [send\_data](http://api.rubyonrails.com/classes/ActionController/). –Steve Streaming.html#M000041 ---

Thanks Steve !! That helps but… send\_data will forward me to a new page. I want to be able to display the chart within the existing page ? I guess I am not really sure how to formulate the send\_data from within the page ?? ---

I’m not sure if it’s possible, as ajax only deals with text based data. However, you might be able to send an ![]() tag that loads a dynamic image… ---

hmmm, a noob ruby question. After I gem install gruff, I opened the irb to try require ‘rubygems’ and require ‘gruff’, and then I got two false. Why? I’m using ruby 1.8.3 on WinXP. I also put the sample code from gruff’s home page into a controller. It seems rails still didn’t know the name of ‘gruff’. Thanks, Sky ---

Steve : No problem. Thanks again for the help !! I think I need to dig in google map apis to try to figure this one out. It must be achievable using javascript. Sky: I have successfully installed Gruff on both linux and windows. For both of these you need to have ImageMagick or GraphMagick installed. You also need Rmagick. Somehow it was not clear from the docs that gruff had these dependencies when I started to look at it… Hope this helps…
