我使用angularjs绘制高清数据。我想根据具体价值自定义标记符号 这是代码
/ Directive Highchart
App.directive('hcChart', function ($parse) {
'use strict';
return {
restrict: 'E',
replace: true,
template: '<div><div class="chart"></div></div></div>',
link: function (scope, element, attrs) {
attrs.chart = new Highcharts.chart(element[0], {
xAxis: {
title: {
text: "Date"
}
},
yAxis: {
title: {
text: "Value"
}
},
dataLabels: {
enabled: true
}
,
title: {
text: ""
},
chart: {
opacity: 0.51,
backgroundColor: "#FFFFFF",
plotBackgroundColor: 'rgba(0, 0, 0, 0.7)',
width: 1600,
height: 800,
zoomType: 'xy',
resetZoomButton: {
position: {
x: -140,
y: 0
}
}
},
tooltip: {
crosshairs: {
width: 2,
color: 'black',
dashStyle: 'shortdot'
}
}
,
exporting: {
buttons: {
contextButton: {
enabled: false
},
exportButton: {
text: 'Download',
tooltip: 'Download',
menuItems: Highcharts.getOptions().exporting.buttons.contextButton.menuItems.splice(2)
},
printButton: {
text: 'Print',
onclick: function () {
this.print();
}
}
}
}
});
Scope to watch categories
scope.$watch(function () {
return attrs.categories;
}, function () {
if (attrs.chart.xAxis.length === 0) {
attrs.chart.addAxis($parse(attrs.categories)(scope));
} else {
attrs.chart.xAxis[0].setCategories($parse(attrs.categories)(scope));
}
});
scope to watch series
scope.$watch(function () {
return attrs.series;
}, function () {
var i;
for (i = 0; i < $parse(attrs.series)(scope).length; i++) {
if (attrs.chart.series[i]) {
attrs.chart.series[i].setData($parse(attrs.series)(scope)[i].data);
} else {
attrs.chart.addSeries($parse(attrs.series)(scope)[i]);
}
}
// remove series if new array passed is smaller
if (i < attrs.chart.series.length - 1) {
var seriesLength = attrs.chart.series.length - 1;
for (j = seriesLength; j > i; j--) {
attrs.chart.series[j].remove();
}
}
});
}
};
}).controller('IndicatorAnalyticsDashboardController', function ($scope, $filter, $http, $timeout) {
$scope.dateBegin = moment().subtract(17, "days");
$scope.dateEnd = moment();
$scope.aggregationSelected = "hourly";
$http({
})
.then(function (listIndicatorsResult) {
$scope.indicators = listIndicatorsResult.data;
$scope.idIndicatorSelected = listIndicatorsResult.data[3];
$scope.idIndicatorChanged();
});
// Chart series default view-------------------------------------------
$scope.myCategories = [];
var opacity = 1;
$scope.mySeries = [
{
type: "area",
name: 'red',
lineWidth: 0,
fillOpacity: 0.65,
color: '#FF0000',
data: [],
marker: {
enabled: false
}
},
{
type: "area",
name: 'amber',
fillOpacity: opacity,
lineWidth: 0,
color: '#e7cd2c',
data: [],
marker: {
enabled: false
}
},
{
type: "area",
name: 'green',
fillOpacity: 1,
lineWidth: 0,
color: '#00ad02',
data: [],
marker: {
enabled: false
}
},
{
type: "area",
name: 'light green',
fillOpacity: opacity,
lineWidth: 0,
color: '#66cd67',
data: [],
marker: {enabled: false}
},
{
type: "spline",
name: 'Actual',
color: "black",
lineWidth: 3.2,
data: [],
我试过这个来更新标记
marker: {
enabled: true,
symbol: this.y > 40 ? "square" : "triangle"
}
},
{
type: "spline",
name: 'Moving Median',
data: [],
color: "#00f6ff",
visible: false,
marker: {
symbol: 'triangle',
width: 16,
height: 16
}
}
];
//and inside function series has been update using:
// // Assign values
$scope.myCategories = $scope.dateData;
$scope.mySeries[4].data = $scope.actual;
// $scope.medianValue = $scope.median.map(Number);
$scope.mySeries[5].data = $scope.median;
$scope.mySeries[0].data = $scope.red;
$scope.mySeries[1].data = $scope.amber;
$scope.mySeries[2].data = $scope.green;
$scope.mySeries[3].data = $scope.lightGreen;
// $scope.mySeries[4].marker = {
// enabled: true,
// symbol: this.x > 4 ? 'circle' : 'square'
// };
console.log($scope.mySeries[4].marker.symbol);
$scope.mySeries[3].marker.enabled = "true";
有人能建议如何根据angularjs中的某些条件更新特定点的标记符号吗?我已经尝试在angularjs控制器中添加内部highchart指令和更新功能。

您可以使用render
事件更新标记:
var redrawEnabled = true;
(...)
chart: {
events: {
render: function() {
if (redrawEnabled) {
redrawEnabled = false;
this.series[0].points.forEach(function(p) {
p.update({
marker: {
symbol: p.y > 100 ? "square" : "triangle"
}
}, false);
});
this.redraw();
redrawEnabled = true;
}
}
}
}
我迭代所有点并根据点的值设置符号。 redrawEnabled
标志用于防止无限递归循环 - redraw
函数调用render
事件。

我们可以使用Angular foreach函数根据控制器内的某些条件更改点的标记符号...
angular.forEach($scope.array, function (value, i) {
$scope.actual[i] = {
y: value.VariableName,
marker: someCondition ? {
symbol: 'url',
width: 23,
height: 23}})
