I’ve tried that way to fix it, but the result is:
it just add “” to the wrong “numeric” X label.
So, what can I do to let the system consider it as an String?
Or if the definition is wrong at the very beginning?
Here’s my definition code:
it’s a jsp page and al4() is an ArrayList<String> type of Java, it stores bunch of date String:
2016-08-04, 2016-08-05, 2016-08-08, 2016-08-09, 2016-08-10..
So can you give me some advise to fix it?
