Using link to change source data of another chart

[andy_c]

Hello,

I am having trouble getting a link to work with some javascript in
ZiYa. Basically what I envision is there will be 5 links on a chart
and if the user clicks these links it will change the source data for
another chart. I was trying to do this using a javascript. Below is
what I have so far:

views folder
_chart.html.erb file:
#######################################################
<center>
<div class="charts">
<div class="chart">
<%= ziya_chart load_chart_url, :id => 'test_chart', :size =>
'1000x550' %>
</div>

<div class="chart">
<%= ziya_chart load_chart_2_url, :id => 'test_chart_2', :size =>
'1000x550' %>
</div>
</div>
</center>
#######################################################

index.html.erb file:
#######################################################
<div id="workspace">
<center>
<%= render :partial => "chart" -%>
</center>
</div>
#######################################################


themes folder -> default folder
floating_bar_chart.yml (ignoring how the spacing appears wrong here,
it is correct)

Also the data for the graph is being generated in the controller. How
do I have the javascript change which set of data is being used for
the graph when this data is being generated in the controller?
Currently this data is randomly being generated and the first chart
updates every 5 seconds to show the changes. Below is the controller
code if needed (the second chart currently uses the same data as the
first chart):


blee_controller.rb
#######################################################

Thanks

[andy_c]

Oops, I realized I did not put double quotes in the javascript alert
call. Original= url: 'javascript:alert('Test')' Correct= url:
'javascript:alert("Test")'

However I am still a bit puzzled how to have the javascript change

which set of data is being used for the graph when this data is being
generated in the controller?

Thanks.

[andy_c]

I think I figured this out. Sorry to waste any one's time. One
question though, I can pass an array from the controller to the style
sheet or does it have to be a hash? Thanks.

Hi Andy,

  Assumed you saw this link http://www.maani.us/xml_charts/index.php?menu=Reference&submenu=Javascript_to_Flash

  You can pass whatever object you want in the user_data directive.

I having issues with passing an array to the style sheet. I do not
know how to access the individual elements of the array. Here is what
I have:

Controller:

chart.add :user_data, :tooltip, @@test_names # test_names is an array
of strings

Style sheet (ignore how the spacing appears here, it is correct in the
yml file)

<%=comp :link %>
areas:
- <%=area :area %>

x: 825
y: 150
width: 40
height: 20
url: 'javascript:update_data_2( )'
tooltip: <%=options[:tooltip[1]]%>

Using <%=options[:tooltip[1]]%> does not seem to work. How do I
access the individual elements?
Thanks.

You mean options[:tooltip][1] ?

[andy_c]

Oops, I feel stupid. I misplaced the brackets. Thanks so much!
