javascript - Highcharts bar chart animation only working on 1 series -


i refreshing data bar chart every x seconds webservice , color coding bar based on value. angular $interval using looks this:

    maininterval = $interval(function() {       console.debug("interval");       (x = 0; x < 5; x++) {         var temp = math.random() * 100;         if (temp > 75) {           $scope.chart.series[x].update({             color: "red"           });           $scope.chart.series[x].setdata([temp]);         } else if (temp > 50) {           $scope.chart.series[x].update({             color: "orange"           });           $scope.chart.series[x].setdata([temp]);         } else if (temp > 25) {           $scope.chart.series[x].update({             color: "yellow"           });           $scope.chart.series[x].setdata([temp]);         } else {           $scope.chart.series[x].update({             color: "grey"           });           $scope.chart.series[x].setdata([temp]);         }       }      }, 5000);

but issue having once goes through interval first time, animation no longer shows bottom 4 bars, top one. example if change interval to

    maininterval = $interval(function() {       console.debug("interval");       (x = 0; x < 5; x++) {         var temp = math.random() * 100;           $scope.chart.series[x].setdata([temp]);         }     }, 5000);

the animations between cycles works colors don't change obviously. ideas address this? here plunker working on.

the problem series.update() remove nice animation. workaround first update colors, setdata(). example: http://plnkr.co/edit/nbzypwoldcrghq4itf59?p=preview - 2 separate for's , need call twice chart.redraw(). it's matter between performance vs design ;) 

    maininterval = $interval(function() {        (x = 0; x < 5; x++) {         var temp = math.random() * 100,             color;         if (temp > 75) {           color = "red";         } else if (temp > 50) {           color = "orange";         } else if (temp > 25) {           color = "yellow";         } else {           color = "grey";         }           $scope.chart.series[x].update({             color: color,             nextdata: [temp]           },false);       }        $scope.chart.redraw();        $.each( $scope.chart.series, function(i, s) {         s.setdata(s.options.nextdata, false);       });        $scope.chart.redraw();      }, 5000);

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
