Hello,
In one of my figure I'd like to add one or more rules below the
xAxis specifying time alignment label info:
xAxis------------------------------------------------------------------
1 2 3 ...
99 100
ruler1--|------------|--------------------|----------------------|------
label1 label2 label3 label n
ruler2--------|--------------------|----------------------|-------------
label1 label2 label3
How can I do that?
Many thanks,
Zhang Le
