Chart Combination

[titus_007]

Hello everyone,
I have problems with the implementation of a combination chart , the following information :

I have a table with ID , NAME , VALUE , TYPE , DATE (DD- MM- YYYY )
example: 1 CAPT1,10 , REAL 19-10-2015
2 CAPT1,15 , PREV , 19-10-2015
3 CAPT2,15 , REAL 19-10-2015
4 CAPT2,10 , PREV , 19-10-2015
5, CAPT1,20 , REAL 20-10-2015
6 CAPT1,20 , PREV , 20-10-2015
etc.

I wish to make a combined graph with the DATE on x, VALUE on Y and a series as area with the values ​​" REAL " and the second series as a curve with the values ​​" PREV " .

Can someone explain to me how to create this combination chart ?

Thank you in advance.
Regards
