Highcharts: Stacked bar chart display categories data, not series -


i have 2 js associative arrays this:

var distrodates = [ {     name: 'exdate',     data: [         '06/25/2013',         '12/17/2012',         '06/20/2012',         '12/19/2011',         '06/21/2011',         '12/20/2010',         '06/21/2010',         '12/21/2009',         '06/22/2009',         '12/22/2008',         '06/23/2008',         '12/24/2007',         '12/21/2006',         '12/23/2005',         '12/23/2004',         '12/22/2003',         '12/23/2002'     ] }, {     name: 'record date',     data: [         '06/27/2013',         '12/19/2012',         '06/22/2012',         '12/21/2011',         '06/23/2011',         '12/22/2010',         '06/23/2010',         '12/23/2009',         '06/24/2009',         '12/24/2008',         '06/25/2008',         '12/27/2007',         '12/26/2006',         '12/28/2005',         '12/28/2004',         '12/24/2003',         '12/26/2002'     ] }, {     name: 'payable date',     data: [         '07/02/2013',         '12/24/2012',         '06/27/2012',         '12/29/2011',         '06/27/2011',         '12/30/2010',         '06/25/2010',         '12/31/2009',         '06/26/2009',         '12/31/2008',         '06/27/2008',         '01/04/2008',         '12/28/2006',         '12/30/2005',         '12/30/2004',         '01/02/2004',         '01/02/2003'     ] } ] var distrodata = [ {     name: 'income',     data: [         0.3908,         0.4948,         0.2311,         0.3342,         0.245,         0.2213,         0.19,         0.1404,         0.2014,         0.2266,         0.2131,         0.2328,         0.1288,         0.0044,         0.6248,         0,         0     ] }, {     name: 's.t. capital gains',     data: [         0,         0,         0,         0,         0,         0,         0,         0,         0,         0,         0,         0,         0,         0,         0,         0,         0     ] }, {     name: 'l.t. capital gains',     data: [         0,         0,         0,         0,         0,         0,         0,         0,         0,         0,         0,         0,         0,         0,         0,         0,         0     ] }, {     name: 'return on capital',     data: [         0,         0,         0,         0,         0,         0,         0,         0,         0,         0,         0,         0,         0,         0.0202,         0,         0,         0     ] } ]

the distrodata array used series. distrodates used categories. want categories display in tooltip (rather usual series data) , want tooltip update category values hover on each bar along x-axis.

the following code accomplished using highcharts v2.1.4/highstock v1.2.5 (both loaded):

            tooltip: {             formatter: function() {                 var s = '<table class="tooltip distro"><tbody>';                 var chart = this.points[0].series.chart; //get chart object                 var categories = chart.xaxis[0].categories; //get categories array                 var index = 0;                 var distrodatapoint;                 while(this.x !== categories[index]){index++;} //compute index of corr y value in each data arrays                 $.each(distrodates, function(i, categories) { //loop through categories array                     s += '<tr><td>'+ categories.name +':</td><td>' + categories.data[index] + '</td></tr>'; //use index peg categories , distro data series                     distrodatapoint = '<tr><td>distribution:</td><td>$' + distrodata[0].data[index] + '</td></tr>';                 });                 s += distrodatapoint + '</tbody></table>'                 return s;             },             shared: true         },

however, when upgraded highstock 1.3.4 (which includes highcharts) while statement locked browser (ff , chrome). browser gave familiar "script non-responsive" alert assume because caught in expensive loop.

any ideas how can rewrite or substitute while performance acceptable?

why don't use shared tooltip? set tooltip.shared = true , work fine. see example how format shared tooltip here.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
