you implement function catch search defining category in category__in array.

global $wp_query; if(is_search()) :     $cat = array(         'category__in' => array(5) // 5 id of music category     ); $args = array_merge( $wp_query->query, $cat ); endif; query_post($args);

or

you way through hidden field - value 22 category

<form method="get" id="search form" action="/"> <div> <input type="text" value="" name="s" id="s" /> <input type="hidden" value="22" name="cat" id="scat" /> <input type="submit" id="search_submit" name="search" value="search"/> </div> </form>

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 .
