Plug In: Heat Map Report

It's a Heat Map (or heatmap) Report Plug-In. It's a representation of data where values are depicted by color. It makes the visualize of complex data easy and understand it at a glance.

This has been inspired by Special thanks to Oracle APEX Product Development team, who brought this solution.

Plug-In Details:

DB versions:,,,,,,,

APEX versions:,,  21.1.0


Go to GitHub and export plugin file "region_type_plugin_orclking_heatmap_report.sql" from Source directory and import it into your application.

Steps to Achieve:

Step 1: Export a script "Script to Populate Sample Data.sql" from directory and compile it in your schema.

Step 2: Create a new blank page.

Step 3: Export plugin file "region_type_plugin_orclking_heatmap_report.sql" from GitHub source directory and import it into your application.

Navigation: Shared Components ==> Plug-ins ==> Import

Plugin will be listed under plug-ins bucket after successful installation.

Step 4: Create a region to the page. Change region type to Heat Map Report [Plug-In].

Step 5: Construct Oracle SQL query and copy and paste it in region SQL Query section.

Query Template:

SELECT 1 heat_map_id, -- Primary key of the Table   
       'Product A' heatmap_tootltip,          
        apex_string.get_initials('Product A',6) heatmap_label, -- Initials          
        apex_util.prepare_url ('f?p='||:app_id||':1:'||:app_session
||':::1:P1_ID:'||1) heatmap_link,          
        1000 heatmap_value -- Note: It must be a number field          
  FROM dual
 WHERE 1 = 1;

Sample Query to Render a Report:

Note: Populate sample data by exporting a script "Script to Populate Sample Data.sql" from GitHub directory and compile it in your schema.

WITH final_data AS    
(SELECT dt.dept_id,     
        count(*) total_tasks       
  FROM dept_tasks dt
 GROUP BY dt.dept_id
   SELECT dept.dept_id heat_map_id, -- Primary key of the Table
          dept.dept_name heatmap_tootltip,         
          apex_string.get_initials(dept.dept_code,6) heatmap_label, -- Initials          
          apex_util.prepare_url ('f?p='||:app_id||':1:'
                                 ||:app_session||':::1:P1_ID:'||1) heatmap_link,          
          fd.total_tasks heatmap_value -- Note: It must be a number field          
     FROM department_master dept,     
          final_data fd          
    WHERE 1 = 1    
      AND dept.dept_id = fd.dept_id      
    ORDER BY fd.total_tasks DESC;

Output: Then you output would display like this,

The demo is here.

That's it.

Happy APEXing!!!...
