Charts... to move bars


I have a base where I have all my patients. now I have a nested IF formula where I tagged them according to age group.
in the chart the age groups are arranged “alphabetically” for example, 1-4 years old, next to 10-14 years old, and I cant change that. and 65+ years old starts the chart, and its unmovable…

a real chart would let you re-arrange your data according to your needs. for example I want to arrange them from younger to older.
