javascript - Highcharts not "graphing" in Firefox or Safari -


i'm having odd problem highcharts graph "graphing" on chrome. graph frame shows fine (the axis' names, labels, white background, etc), actual columns not animated, nor show on graph represent actual data. appears empty graph.

the data being called via ajax. on end fine. code simple, not sure causing this. here code, appreciated:

highcharts.chart('modal-graph-wrapper', {             chart: {                 type: 'column'             },             title: {                 text: 'build time vs. step'             },             yaxis: {                 title: {                     text: 'length of time (seconds)'                 },                 categories: timearray             },             xaxis: {                 categories: namearray             },             plotoptions: {                 series: {                     pointstart: 0                 }             },             series: [{                 name: 'build time (seconds)',                 data: timearray,                 linewidth: 3,                 marker: {                     radius: 3,                     fillcolor: '#337ab7'                 }             }]         });

i ended figuring out. because date.parse function not work expected in firefox or safari; whereas in chrome works anticipated. restructuring time format solved issue. thanks!

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
