javascript - Angularjs and Highcharts directive in Nested object -


in application create directive draw highcharts chart . 

  app.directive('chart', [function () { return {     restrict: 'e',     scope:{         config :"=",         chartobj: "=?"     },     link: function (scope, ielement, iattrs) {         scope.chartconfiguration = {};         /*scope.$parent.$watch('conf',function(value){             console.log("aaa");         });*/         scope.$watch('config',function(value){             console.log("1111111111111");             console.log(scope.config);             if(value==null)                 return;             var b = angular.tojson(scope.config);             /*if(($('.main-div').find('pre').html())!=null)                 $('.main-div pre').remove();*/             $('.main-div pre').html("<pre class='.configuration'>"+angular.tojson(scope.config)+"</pre>");             scope.chartconfiguration.chart = scope.config.options.chart;             scope.chartconfiguration.series = scope.config.series;             scope.chartconfiguration.chart.renderto = ielement[0];             scope.chartobj = new highcharts.chart(scope.chartconfiguration);         });      } }; }])

in directive use $watch watch properties of object. it's watch on property not nested. forexample if want change $scope.conf.options.chart.type watch doesn't understand . problem create plunker

you use $watch third argument, objectequality flag, set true this:

scope.$watch('config',function(value){   // code }, true); // set objectequality flag true here

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
