APEX

Here I am trying the APEX assistant in APEX to turn natural language to visible result likes report/sheet or chart (bar or pie). I try to provide prompt and rag in the AI configurations. But the output of the AI assistant hard to fix my expected. The data in table/sheet are OK, but most of the charts are not.

Here is the sample result. I ask a question but the bar chart is hard to shown.

Sometimes, the bar chart can be shown properly.

Sometimes the charts are not shown with error as below.

I tried different prompt and RAG configuration, but most of them are hard to give me the expected result.

below is one kind of my prompt (with the sample data DEPT and EMP).

<div class="ai-assistant-prompt">
  <h3>Oracle APEX Departments & Empolyees Information System</h3>
  
  <div class="assistant-role">

below is the RAG I created based on the SQL query that I used in the top sreenshot, the DEPT and EMP join query.
