I have connected to SQL Server database (server-side vbscript) and read some
data from the tables. This works correctly. I now have the data in an array
(server-side).
I have to draw a line-chart based on that data, for which purpose I need to
create client-side component (this works also perfectly).
PROBLEM: I cannot use the server-side array for drawing the chart.
Here's the code shortly:

Idea.
Write out Javascript that 'creates' an array on the client side to then pass
to the component.
eg.
Response.Write "<SCRIPT language=Javascript>"
Response.Write " var parrArray = new Array();"
Response.Write " parrArray = '[12,13,14,15]';"
Response.Write "</SCRIPT>
Of course the 12...15 would be output probably by a loop of some sort.
Anyway, once you have the array at the client end then pass that to the
client-side component.
Hope this helps.

I use this technique alot ... 'cept I get lazy with my response writes
.... just throw the array into a delimited string, and write the string
into the javascript
Response.Write "var arrString = " & yourDelimitedString
then just include the split command to get this into your array

Notes:
1. When referencing a database, please provide DDL and sample data.
Here's an article: http://aspfaq.com/5006
2. Please consider using a DSN-Less OLEDB connection string. Here's an
article: http://aspfaq.com/2126
3. Please try to avoid using "SELECT *". Here's an article: http://aspfaq.com/2096
