When I use format: 'QQQ yyyy' for haxis, there are too many grid lines showing such as
Q1 2000, Q1 2000, Q1 2000, Q2 2000, Q2 2000, Q2 2000, Q3 2000 ...
Each different quarter repeating 3 times, how to control it to only show different quarter once, such as
Q1 2000, Q2 2000, Q3 2000, Q4 2000
Also is it possible to show it in two lines,such as
Q1
2000
