highcharts - fHighcharts Isomorphic rendering / web-workers -


we have application renders ~50 (high)charts simultaneously on dashboard. thing browser freezes when charts getting rendered. (i tried using boost , virtual scroll). makes worse our users have datalabels on.

a fiddle experiments: http://jsfiddle.net/z9msdftt/1/

var to; $('#charts').scroll((e) => {     cleartimeout(to);         = settimeout(() => {         var offset = math.floor($('#charts').scrolltop() / 400);         var start = new date();         [...array(5)].foreach((_, i) => {             renderchart(offset + i);         });         var end = new date();         $('#counter').html('time rendering: ' + (end - start) + 'ms');     }, 50); });

is there way can speed maybe by:

  1. doing initial server rendering of svg , handle further interactions on client side (isomorphic render)

or

  1. using webworkers calculations parallely , rendering charts.

any help, appreciated.

you can try highcharts boost.js speed rendering process.

this speed problem general in svg based chart libraries. performance decreases after adding couple hundreds of points chart or adding multiple charts same page.

boost.js using html5 canvas technology drawing graph on html5 canvas copying content of chart svg.

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
