i need some help doing an area chart on apexcharts, i'm passing an irregular series

[
    {"name":"Fase 1","data":[140,140,null,null,null,null]},
    {"name":"Fase 2","data":[null,140,150,150,null,null]},
    {"name":"Fase 3","data":[null,null,null,150,160,160]}
]

actually using xaxis type categories with this categories:

['00:00:00', '00:15:00', '00:15:00', '00:30:00', '00:30:00', '00:45:00']

At the moment i'm able to see this graph

and I want to achieve this more aggressive stroke angle
