i have bunch of monthly datetime based data points need map in line chart. trying accomplish: i need points plotted on chart i need line charts of 3 series begin on first data point @ bottom left (january 1st). the first data point needs display text phrase , rest need remain formatted date. please take @ jsfiddle. http://jsfiddle.net/fwgdw/7/ $(function () { $('#container').highcharts({ chart: { type: 'spline' }, title: { text: 'performance chart' }, subtitle: { text: 'monthly date inverval' }, xaxis: { type: 'datetime', datetimelabelformats: { month: '%b-%y', year: '%b-%y'}, /*showfirstlabel: false, startontick: true*/ }, yaxis: { min: 0 }, tooltip: { headerformat: '<b>{series.name}</b><br>', pointformat: '{point.x:%e. %b}: {point.y:.2f} m'}, seri...

i understand gmpy2 supports gmp library , numpy has fast numerical libraries. want know how speed compares writing c (or c++) code gmp. since python scripting language, don't think ever fast compiled language, have been wrong these generalizations before. i can't gmp work on computer, can't run tests. if could, general math addition , maybe trig functions. i'll figure out gmp later. numpy , gmpy2 have different purposes. numpy has fast numerical libraries achieve high performance, numpy restricted working vectors or arrays of low-level types - 16, 32, or 64 bit integers, or 32 or 64 bit floating point values. example, numpy access highly optimized routines written in c (or fortran) performing matrix multiplication. gmpy2 uses gmp, mpfr, , mpc libraries multiple-precision calculations. isn't targeted towards vector or matrix operations. the python interpreter adds overhead each call external library. whether or not slowdown significant depends on...

i made isactive function set active class on menu element. the function follow: $scope.isactive = function (path) { if (path == $location.path()) { return true; } else { return false; } } in html use: <li ng-class="{active: isactive('/page')}"> <a href="page">page</a></li> but html defined once in template. great use: isactive('/page*') so beyond '/page' url active state. does knows workaround, because haven't found yet on forums , angular documention, guess isn't there yet.. possibly ? $scope.isactive = function (path) { var strregexpattern = '\\b'+path+'\\b'; if( document.location.pathname.match(new regexp(strregexpattern,'g')) ) { return true; } else { return false; } } i don't know if can substitute document.location.pathname.match(... // vani...
