php - Filtering the $allowedtags global in WordPress -


i'm trying filter $allowedtags global in wordpress users can submit html elements in comments.

this how i'm doing it:

function my_allowed_tags() {     global $allowedtags;     $allowedtags['pre'] = array( 'style' => array() ); } add_action( 'init', 'my_allowed_tags' );

this allows use of <pre> tags in comments along default list of tags allowed $allowedtags such <p>, <a>, <img> etc.

how can initialise $allowedtags global no tags allowed default?

ref: http://codex.wordpress.org/global_variables#admin_globals

add filter resets global empty array before current action fires.

function reset_allowed_tags() {     global $allowedtags;     $allowedtags = array(); } add_action('init', 'reset_allowed_tags', 0);

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
