amCharts avec AngularJS
Je cherche encore à faire fonctionner d'autres bibliothèques avec AngularJS en raison de la logique différente de celle des autres bibliothèques. Je dois visualiser les données avec amCharts Stock, mais rien ne permet de les comparer.
Comment puis-je faire ce travail avec angularjs: http://jsfiddle.net/922JW/
var chart = AmCharts.makeChart("chartdiv", {
type: "stock",
"theme": "none",
pathToImages: "http://www.amcharts.com/lib/3/images/",
categoryAxesSettings: {
minPeriod: "mm"
},
dataSets: [{
color: "#b0de09",
fieldMappings: [{
fromField: "value",
toField: "value"
}, {
fromField: "volume",
toField: "volume"
}],
dataProvider: chartData,
categoryField: "date"
}],
panels: [{
showCategoryAxis: false,
title: "Value",
percentHeight: 70,
stockGraphs: [{
id: "g1",
valueField: "value",
type: "smoothedLine",
lineThickness: 2,
bullet: "round"
}],
stockLegend: {
valueTextRegular: " ",
markerType: "none"
}
},
{
title: "Volume",
percentHeight: 30,
stockGraphs: [{
valueField: "volume",
type: "column",
cornerRadiusTop: 2,
fillAlphas: 1
}],
stockLegend: {
valueTextRegular: " ",
markerType: "none"
}
}
],
chartScrollbarSettings: {
graph: "g1",
usePeriod: "10mm",
position: "top"
},
chartCursorSettings: {
valueBalloonsEnabled: true
},
periodSelector: {
position: "top",
dateFormat: "YYYY-MM-DD JJ:NN",
inputFieldWidth: 150,
periods: [{
period: "hh",
count: 1,
label: "1 hour",
selected: true
}, {
period: "hh",
count: 2,
label: "2 hours"
}, {
period: "hh",
count: 5,
label: "5 hour"
}, {
period: "hh",
count: 12,
label: "12 hours"
}, {
period: "MAX",
label: "MAX"
}]
},
panelsSettings: {
usePrefixes: true
}
});
Merci.
Je voudrais créer une directive de base (isolate scope) qui reçoit les paramètres de graphique et l'utiliser comme modèle:
<div id="container"></div>
De plus, nous pouvons écrire plusieurs observateurs pour écouter les actions des utilisateurs.
Voici un exemple de travail Comment l'utiliser:
(Ce n'est pas basé sur vos paramètres mais vous pouvez utiliser le même flux)
Démo Fiddle
Directive
myapp.directive('myElem',
function () {
return {
restrict: 'E',
replace:true,
scope: {
config: '='
},
template: '<div id="container" style="min-width: 310px; height: 400px; margin: 0 auto"></div>',
link: function (scope, element, attrs) {
var chart = false;
var initChart = function() {
if (chart) chart.destroy();
var config = scope.config || {};
chart = new Highcharts.Chart(config);
if(config.loading) {
chart.showLoading();
}
};
initChart();
scope.$watch('config.loading', function (loading) {
if(loading) {
chart.showLoading();
} else {
chart.hideLoading();
}
});
scope.$watch('config.series[0].type', function (type) {
chart.series[0].update({type: type});
});
scope.$watch('config.series[0].dataLabels.enabled', function (enableDataLabels) {
chart.series[0].update({dataLabels: {enabled: enableDataLabels}});
});
}//end watch
}
}) ;
L'usage:
<my-elem config="chartConfig"> </my-elem>
[EDIT]
Démo 2 FIddle
HTML
<div>
<my-elem ></my-elem>
</div>
JS
var myapp = angular.module('myModule', []);
myapp.directive('myElem',
function () {
return {
restrict: 'E',
replace:true,
template: '<div id="chartdiv" style="min-width: 310px; height: 400px; margin: 0 auto"></div>',
link: function (scope, element, attrs) {
var chart = false;
var initChart = function() {
if (chart) chart.destroy();
var config = scope.config || {};

Utilisez le module https://github.com/natanielpaiva/angularAmChart
ou
exemple de projet https://github.com/natanielpaiva/angularAmChartSimples
Simple:
<amchart ng-model = "objectLiveAmchart"> </ amchart>
En Javascript:
$ scope.objectLiveAmchart = {type: serial, ...}
Je me rends compte que la solution fournie ne fonctionnait pas pour moi.
En particulier, le graphique n'indiquait pas si l'identifiant dans le modèle n'était pas codé en dur.
Cela semblait être un problème avec la fonction AmCharts.makeChart() qui n'était pas capable de trouver le chardiv_iddans le DOM.
J'ai trouvé que placer la fonction initChart() dans une scope.$watch('element') (après avoir associé element à la portée de la fonction de liaison) était la solution qui me convenait le mieux.
Je pense que cela est dû au fait que, après la création de element (après l’appel de la montre), il est présent et visible dans le DOM, afin que la fonction AmChart puisse le visualiser et restituer correctement le graphique.
J'espère que cela a aidé quelqu'un!
