* Do not always show graph title. Setting the default title too early cause the titles to always be shown. AFAIK, they should only be shown when: - title is set by the user or graph itself (not 100% sure) - the title variable is set * Use default for empty titles too * Don't clean titles so aggressively * Only show title if explicitly shown * A little more consistent default titles * use built-in escape * Actually show user titles if set Handle single quotes in title * initialize title * $title doesn't need to be nullable add method getTitle() to always get some text * Revert incorrect formatting change * whitespace fix
