I've been strugling for weeks trying desperatly to get a simple bar-chart out of a MySQL database. The data base keeps the results of a simple test with : date, first name, last name, and the number of points for each answer to the 20 questions.

The problem is that I can't get a chart out one single row with 20 series (the results of one candidate), I get only one bar.

When I use :

   result = mysql_query("SELECT * FROM  xxxx");

I get a chart with the results of all candidates to the first question (1 bar for each).

With the following code :

   result = mysql_query("SELECT * FROM  xxxx WHERE id=1");

I obtain one and only bar.
