Hi,
I am using VS 2010.I am new to this (AJAX RAD Controls/AJAX RAD Charts).I am having an xml file having 3 tables.Now my requirement is to plot a Stacked bar Chart dynamically retrieving values from different tables.Kindly help me out.

I have retrive values from different table into One Datatable named "ValuesToDisplay"

05:30  06:00  06:30  07:00  07:30  08:00  08:30  09:00  09:30  10:00  
 01     02     01     04     04     02     03     04     03     05     
 02     04     01     04     05     03     01     04     01     01     
 03     03     02     02     01     04     02     02     03     05    

Now on X-axis should be the Time(ie 05:30 ......) and on Y-axis the values(ie 1 2 ...). Graph should be in this format:
