Dear APEX gurus, I am new to APEX.
I am working on a data visualization project, I have a bar chart showing the data for EASTERN and WESTERN area, each area contains a number of districts, and each district contains a number of sites.
I want to click on EASTERN and the data for every district of EASTERN to show up, clicking one of the district of EASTERN, then the site data for the district shows up. is it doable in APEX? how to implement it step by step? is ojgroupdrill relevant to this application? any input or advice or suggestion is welcome. Thank you in advance.
