How to make a grouped BarChart with ios-charts?

Question

I am using ios-charts library.

I would like to group my inverter values so that each year is one group. Unfortunately, the number of monthly values per year may vary

Answer 1

if you have noticed in above code in function chart. There is let

 groupSpace = 0.3
 let barSpace = 0.05
 let barWidth = 0.3
 // (0.3 + 0.05) * 2 + 0.3 = 1.00 -> interval per "group" 

which will make equation (groupSpace * barSpace) * n + groupSpace = 1

you need to play around this equation for n number of bars
