Rails - Sep 2007 - Need assistance figuring out the logic for my controller

Good afternoon,

I''m working on a small app that generates some dynamic charts using
JFreeCharts.

I have a view that contains some different chart links in a side bar.
Then in the center of the page I have a div for the charts.  When
clicking a chart link I would like to do the following:

- Place a spinner in the chart display div
- Generate CSV file of data to disk (I''ve got an array with the data,
writing it is no problem)
- Generate chart from CSV file (done using this technique:
http://wiki.rubyonrails.org/rails/pages/HowtoGenerateJFreeCharts)
- Display chart in the main div

Can this be done using an RJS template?

I built a skeleton RJS template so it would mimic what I ultimately
want to do for my page:

page.replace_html :chartStatus, ''<h2>Generating your chart
data.</h2>''
page.visual_effect :highlight, ''chartStatus'', :duration =>
3
page.replace_html :chartDisplay, ''<img src="../../images/
spinner.gif">''
 page.delay(5) do
    page.replace_html :chartStatus, ''<h2>Done.  Click chart for
larger
version or right click to save.</h2>''
    page.visual_effect :highlight, ''chartStatus'', :duration
=> 3
    page.replace_html :chartDisplay, ''Chart goes here.''
 end

I''ll plug away and see if I can find any other instances of this,
thanks in advance for any help.
-Matt
