  Hi swatantra ,thanx for your replay it is some what helpfull also i have modified your example like this

='Server Size: ' & Q_CPU1 & chr(13) &

'Finance Type:' & N_FINCG_TYP1& chr(13)&

'Total Servers: ' & Num(Count(SERVER), '#,##0') & chr(13) &

in chart it  displays this Server Size: Small

                                   Finance Type: Leased

                                   Total Servers: 10000

Actually we have catagorized the server size as below small: Between 0 and 2

                                                                           Medium: Between 3 and 4......etc

here i want to show add one more line to the above number of CPU's: 0 to 2 for small,, 3 to 4 Medium....etc

how can we add this info also........
