We’ve just got down with the first implementation of  
ZiYa. This rails plugin allows you to display elegant  
charts on your webapps, the easy way…

Check out at the details at [http://liquidrail.com](http://liquidrail.com).

Best wishes to all for the new year !!

Take a look at SWF/XML Charts ( [maani.us](http://www.maani.us/xml_charts/) ) to  
get more info on how the charts are constructed. The answer is “sort  
of”: the Flash chart component reads the XML data when it is rendered  
on the screen (the URL to the XML appears in the HTML which embeds the  
Flash object).

I am glad to see this plugin released as it means there is one less  
thing I have to maintain in my code base. 🙂

Make sure this gets listed on the plugins site. If I understand  
correctly, this plugin sends down some XML data to the client that gets  
rendered in a SWF client. Is that right?

Thanks !!

We have tried to list the ZiYa plugin in most sites we knew off. If you  
have suggestions  
about other sites, we could list on that would be great.

Indeed ZiYa leverages XML/SWF Charts but hides the XML generation part  
from the  
developer. Within a couple of API calls you should be able to have a  
chart rendered in  
you web app. For instance in you controller you can do something like  
this:

```
def sales
   chart = Ziya::Charts::Bar.new
   chart.add(:axis_category_text, %w{ 2002 2003 2004 2005 2006 })
   chart.add(:series, "Sales", [10, 15, 20, 25, 30])
   render :text => chart
end

```

Then in your view code:

```
<%= gen_chart( "sales_chart",
                 url_for( :controller => 'my_controller', :action =>

```

‘sales’ ),  
“#ffffff”, 400, 300 ) %\>

We’ve also leveraged YAML and ERB to enable you to style the chart  
just like  
you would for HTML and stylesheets. The cool thing here ( so we  
think… ) is  
that you can dynamically style your charts based on some model  
state.  
For example, if you want a certain aspect of the chart to change  
color based  
on some threshold, you could override the style sheet with something  
like this:

\<%=comp :series\_color%\>  
\<%if @options[:sales] \> 10%\>  
colors: ff0000,aa0000  
\<%else%\>  
colors: 0000bb,00cc00  
\<%end%\>

```
 If this looks less than ideal you can also define a ZiYa helper

```

function which would render  
the code above as such:

```
<%=comp :series_color%>
    <%= custom_colors @options[:sales]%>

```

There is more info about that in the rdocs.  
[http://ziya.liquidrail.com/rdoc](http://ziya.liquidrail.com/rdoc).

Thanks for checking us out !!
