Change Y axis labels in C3 charts

Is it possible to change or categorize the Y axis labels in C3 line chart.

Is it possible to categorize and display the Y axis labels as "Beginner","Intermediate", "Advanced" and "Mastery" where the values would be ranging between 0-25, 25-50, 50-75, 75-100 respectively?
