Problem related to query

Question

Hello Everybody...
I have some prblem regarding to query.
In my problem i m not getting that which query i have to apply to get solution...
My problem is this
Basic tables are
Pa_Project_all
Project_id (Primary Key)
Project_type
Task_id
Pa_location
Location_id
Location_name
pa_tasks
task_id     
task_name
pa_category
asset_category_id
cataegory_name
And here i have data in table Pa_Project_assests_all
project_id     1     2
asset_name     TRUCK     SUMO
location_id     PARIS PARIS
Asset_category_id 333     555
Asset_unit          30     10
Cap_flg N N
Cap_date 12Dec 12Dec
Est_date 15Dec 18Dec
Cap_cost 1000 1000
IMPORTANT Table:
Pa_project_assets_All_audit_table
Project_id     1     1     1     2     2     2     2
Updated_by     Xx     aa     bb     Yy     Xx     Tt     YY
Updated_date     10     11     12     10     10     12     12
Updated_time     2.00     2.05     2.10     2.0     2.05 2.10     4.00
Asset_name     Tempo               Jeep               
location_id          London                         
Asset_category_id                                   
asset_unit                    10                    
Cap_flg                         Y          
Cap_date                                   
Cap_cost                              2000     1500
USER MAKE CHANGES IN ANY FIELD IN PA_PROJECT_ASSET_All are automatically insert one record in pa_project_asset_all_audit_table for every change.
Say if user changes only asset_name from ‘truck’ to ‘tempo’ one record is inserted in audit table with system current date,time and username.
Say if user changes only asset_unit, another record is inserted to my audit table
I want the report which should print me the original record and the last updated record
From audit trail table.. see here the last 2 record of audit table, the only cap_cost is changed from 1000 to 2000 and again from 2000 to 1500.
So my record of cap_cost 1500 will only show on my report and not record with 2000.
While all other record have different changes in different column,.so in case of project id 1 all three changes record should be displayed with original information from pa_project_assets_all.
While for project_id 2 only first 2 and 4 record will display.
Please remember that 3rd record of project id 2 should not be displayed because the same column is changed again with cap_cost.so only last changes in that particular column with respective project should be shown.
I m not getting which query i have to write so i get this kind of data.
Please any 1 have idea then reply me.

Hi Upen,
1. If u want only 15 vendors to display as histogram every time for each plant then u have to restrain ur query output by filtering with appropiate characteristics.
or otherwise
2. On right clicking the chart area u can find a chart wizard from where u can select the cells of which the histogram is to be displayed.
