Oracle APEX Chart Conditional Bar Colors

 


 Here I am giving an example to change the chart bar colors based on the conditions in Oracle APEX.

Step 1: Create a new blank page.

Step 2: Create a bar chart region and your bar chart series query would then look something like this,

SELECT fund_id, 
       fund_name, 
       to_char(start_date,'DD-Mon-RRRR') start_date, 
       case when percent_complete >= 75 then '#d1f5e0' --light green
            when percent_complete >= 50 then '#fff4dd' --light orange
            when percent_complete <= 50 then '#fdd5cc' --light red
       else 'blue'
        end as color,
       percent_complete
FROM fxgn_fund_progress order by fund_id ASC

Step 3: Do the column mappings. (Label and Value must be mapped)

Once you done the above setup, then your bar chart would then look like this,

Step 4: [Enable Conditional Bar Colors] 

Click on the chart series and look for the attribute "Color" (Which you could find under the option "Appearance") and Substituting your value using the syntax &COLUMN_NAME. 

Output: Output would then look like this,


The demo is here.

That's it. I hope this example will help you to understand how colors of the chart bars can be changed based on the conditions. 

Happy APEXing!!!...

Here I am giving an example to save selected interactive grid records into a oracle apex collection. Step 1: Create a new blank page. Note: Mine was page 20. You will need to update reference to " P20 " with your page number if it's different. Step 2: Create a new interactive grid report region to the page using below query. Set Static Id "EmpDetails" to the region. SELECT  *     FROM   ( SELECT  emp . empno ,                emp . ename ,                emp . JOB ,                dept . dname department ,                dept . loc  LOCATION ,                mgr . ename  manager ,                emp . hiredate ,                 nvl ( emp . sal , 0 )  salary ,                 nvl ( emp . comm , 0 )  commission            FROM  eba_demo_chart_emp emp ,                eba_demo_chart_dept dept ,                eba_demo_chart_emp mgr           WHERE  emp . deptno = dept . deptno             AND  emp . mgr      = mgr . empno  ( + )           ORDER   BY  emp . ename
