Create a custom axis line in a combo chart

Greeting all 

im trying to make a combo chart with a custom axis column for one of my client ! 

let's say i have a table that contain this column : Offer name | Status | duration of publishing 

=> i want to calculate  the number of offers that have a status= false  and i want them to be distributed in a combo chart according to the following  :  2 week of publishing , 1 month of publish , more than 1 month of publishing 

Well the first part is pretty easy but how im gonna distribute the number of offers in the combo box ? is there a way to create a custom one ? or a way to control the axis line ! 

Thanks in advance !
