Hi sir i want to communicate with you,can you please share your mail id?
These are the core calculations for above gantt chart. You can duplicate this chart to crosstab to understand individual calculations.
I first built a cross tab with calculations and then converted it to chart.
I would suggest try removing each element from the chart step by step to understand its function. that would help you understand it better.
