As a reminder, here is the way of simply I did use previously to draw a Highcharts chart from JSON data :
$(document).ready(function() {
var options = {
chart: {
renderTo: 'graph_retard_refund',
type: 'area',
marginRight: 130,
marginBottom: 25
},
title: {
text: 'Nbre Commandes en Retards de remboursement par mois',
x: -20 //center
},
subtitle: {
text: '',
x: -20
},
xAxis: {
categories: []
},
yAxis: {
title: {
text: 'Nb de Commandes'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
formatter: function() {
return '<b>'+ this.series.name +'</b><br/>'+
this.x +': '+ this.y;
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -10,
y: 100,
borderWidth: 0
},
plotOptions: {
area: {
stacking: 'normal',
lineColor: '#666666',
lineWidth: 1,
marker: {
lineWidth: 1,
lineColor: '#666666'
}
}
},
series: []
}
$.getJSON("http://localhost/boot/late_payment.php?function=controle_remboursement_retard¶m=graph", function(json) {
options.xAxis.categories = json[0]['data'];
options.series[0] = json[1];
chart = new Highcharts.Chart(options);
});
});
Now, if you want an automatic refresh of the graph every minute, you will to use the "destroy()" function from HighCharts and the well-known setinterval JavaScript function :
( see http://stackoverflow.com/questions/11752320/auto-refreshing-highcharts-with-php-js)
$(document).ready(function() {
var options_payment = {
chart: {
renderTo: 'graph_retard_payment',
type: 'area',
marginRight: 130,
marginBottom: 25
},
title: {
text: 'Répartitions du nbre Commandes en Retards de paiements dans le temps',
x: -20 //center
},
subtitle: {
text: '',
x: -20
},
xAxis: {
categories: []
},
yAxis: {
title: {
text: 'Nb de Commandes'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
formatter: function() {
return '<b>'+ this.series.name +'</b><br/>'+
this.x +': '+ this.y;
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -10,
y: 100,
borderWidth: 0
},
plotOptions: {
area: {
stacking: 'normal',
lineColor: '#666666',
lineWidth: 1,
marker: {
lineWidth: 1,
lineColor: '#666666'
}
}
},
series: []
}
$.getJSON("http://localhost/boot/late_payment.php?function=controle_paiement_retard¶m=graph", function(json) {
// $('#graph_retard_payment').highcharts().destroy();
// if(chart) chart.destroy();
options_payment.xAxis.categories = json[0]['data'];
options_payment.series[0] = json[1];
chart = new Highcharts.Chart(options_payment);
$("#hour_retard_payment").text('à '+ getActualHour());
});
var autoRefreshGraph_retard_paiement = setInterval(function() {
$.getJSON("http://localhost/boot/late_payment.php?function=controle_paiement_retard¶m=graph", function(json) {
// $('#graph_retard_payment').highcharts().destroy();
if(chart) chart.destroy();
options_payment.xAxis.categories = json[0]['data'];
options_payment.series[0] = json[1];
chart = new Highcharts.Chart(options_payment);
$("#hour_retard_payment").text('à '+ getActualHour());
});
} , delay);
}
);
