Line chart displays date in the incorrect format. It should respect the formatter options.

Currently:
-Choosing Plain as the formatter displays the date in YYYY-MM-DD HH:MM:SS format.
-Choosing Date & Time as the formatter displays the date in the correct format, but shows the HTML tag surrounding the field, whether or not you've set the Style Settings to strip out all html or not. It'd be fine to keep the html if it used it to format the field, but it just displays the tags before the date information.
