open_flash_chart's Introduction

OpenFlashChart  Version 2.0.0  11/14/2008 
==============

1) rails ofc2_test_app
2) cd ofc2_test_app
3) script/plugin install git://github.com/pullmonkey/open_flash_chart.git
3.1) If the install didn't copy the contents of the assets directory to your RAILS_ROOT/public directory, make sure to do so.
4) script/generate controller test_it

5) Add the following to the test_it_controller.rb in RAILS_ROOT/app/controllers:
class TestItController < ApplicationController
  
  def index
    respond_to do |wants|
      wants.html {
        @graph = open_flash_chart_object( 600, 300, url_for( :action => 'index', :format => :json ) )
      }
      wants.json { 
        chart = OpenFlashChart.new( "MY TITLE" ) do |c|
          c << BarGlass.new( :values => (1..10).sort_by{rand} )
        end
        render :text => chart, :layout => false
      }
    end
  end

end

6) Add the following to index.html.erb in RAILS_ROOT/app/views/test_it/:
<html>
<head>
  <script type="text/javascript" src="/javascripts/swfobject.js"></script>
</head>
<body>
<%= @graph %>
</body>
</html>

7) script/server
8) Let me know how it goes, thanks.


Example
=======

Example above and more to follow here - http://www.pullmonkey.com/projects/open_flash_chart

Notes
======
The plugin breaks if the json gem is included, because of the way that the gem generates json vs the rails native json generator.

Not tested, but klochner claims to have implemented a fix for it here - http://github.com/klochner/open_flash_chart/commit/00cf531387880af8c49ed5118737f0492b437f75

open_flash_chart's Issues

Can't render more than one graph per page using js helpers

When one tries to render more than one graph js loading function override each other.

I am using the latest version of open_flash_chart on Ubuntu 10, ff 3.5.9. I am loading graphs dynamically using the technique mentioned here http://pullmonkey.com/2008/09/23/open-flash-chart-ii-javascript-part-3/comment-page-2/#comment-11768. and I notice everytime I do that, there is big cpu spike in firefox, obviously because of swfobject. Has anyone else seen this?

set_lables goes in reverse order

I am creating a horizontal bar graph and setting the values - here is my pseudocode
loop...
b.append_value(v)
labels << lable corresponding to value v
end loop

After all the values are built, I want to set custom labels for the Y axis.
y.set_labels( labels )

The labels show up in reverse order to the values I set. So I have to set labels like this...
y.set_labels( labels.reverse )

Possibly this is a bug?

Rails 3

Heads up: If you want the graph to display in Rails 3.0, your template must use <%= @graph.html_safe %>

Update readme documentation

Hi, great job.

You should add to readme that is you need to copy the contents of the 'assets' folder of the plugin to the 'public' folder of redmine, this way will be very easy to deploy your plugin.

Thanks

how to change background color?

Issue with Bar3d

The following json should show two 3d bars (Energy and Water Efficient) with values 253, 400 and 48, 400. But I see two bars labelled (Energey and Water Efficieny, which is correct), with values 253,48 and 400,400.

Is my assumption correct or is this json being rendered incorrectly?

{"title":{"text":"Eco points by category"},"colours":"#38E081","elements":[{"text":"Energy","colours":"#38E081","font-size":3,"type":"bar_3d","values":[253,400],"grid-colour":"#000000"},{"text":"Water Efficieny","colours":"#38E081","font-size":3,"type":"bar_3d","values":[48,400],"grid-colour":"#000000"}],"y_axis":{"steps":100,"max":500,"min":0},"grid-colour":"#000000","bg_colour":"#ffffff","x_axis":{"labels":{"labels":["Energy","Water Efficieny"]}}}

Horizontal Bar Graph Tooltips

Hi - this is a fantastic plugin!

I am having a problem with horizontal bar graphs. If I set all starting values to zero, the mouseover tooltip gets confused and jumps around oddly. If I stack all of the bar values so there are no overlaps, the mouseover works fine. I think this is a bug in the SWF maybe?

thanks!

Can't set y label color

YAxis labels seem to be pretty buggy in general.. but specifically:

I can't figure out how to get even simple labels (step) to work on the y-axis with a color other than #FFFFFF. My graphs are using black as the background color, so the labels just won't show up.

I've tried hacking it in several different ways but with no positive result. Some help would be appreciated!

how to set label unix dates

Hello,
I found this http://teethgrinder.co.uk/open-flash-chart-2/x-axis-date.php
instructions for using dates for labels, but don't know how to do this with the rails plugin
x = XAxis.new
x.set_labels( ["a", "b"])
and the result is strangely (includes labels twice)
..
"x_axis":{"labels":{"labels":["a","b"]}},
..

x.set_labels expects an array of label strings, not sure how to set the label text format to #date:l jS, M Y#

Do you have an example on a line chart with dates for x axis from unix dates?

thank you !

Pb with LineDot and LineHollow

I'm trying to render the multiple lines example but the only line I'm seeing is the "Line.new".
LineDot and LineHollow can't be seen.

Is there any way to make it possible?

problem with scatter - hidden points

Hello,
I experienced a problem with scatter points. If the mouse is on the plot the dots appear, but they suddenly disappear if the mouse goes out.
If the mouse is out nothing appear at all.
If I go on the supposed point location the point comes out with the correct label.
I tried with all sfw files I could download, from both this repository and teethgrinder) and I tried all combination of tips, no tips, and kind of data.
I also copied and pasted the example code and it behaves not like in your example page, but like my disappearing ones.
Any suggestions?
Thanks a lot
Gianluca
