AMCharts Stacked Bar Charts

I have created a stacked bar chart:
https://stackblitz.com/~/github.com/jbiddulph/stackedbarchart

I would like to have 3 shades of green and 3 seperate values in my green Active Travel bar 2.4%, 4.2% and 38.5%

Also Private Motorised should have 2 values 5% and 15% so should be pink and red

and I also need to have a legend

Can someone please help?
