Thank you very much for your answer.

I’ve changed a bit my code

1- is my load function

function displayChart(datapointss){
alert(datapointss);
var chart = new CanvasJS.Chart(“chartContainer”,
{
zoomEnabled: false,
animationEnabled: true,
title:{
text: “PROJECTS”
},
axisY2:{
valueFormatString:”0.0 days”,
interlacedColor: “#F5F5F5”,
gridColor: “#D7D7D7”,
tickColor: “#D7D7D7”
},
theme: “theme2”,
toolTip:{
shared: true
},
legend:{
verticalAlign: “bottom”,
horizontalAlign: “center”,
fontSize: 15,
fontFamily: “Lucida Sans Unicode”
},
data:[{
datapointss
}
]
,
legend: {
cursor:”pointer”,
itemclick : function(e) {
if (typeof(e.dataSeries.visible) === “undefined” || e.dataSeries.visible) {
e.dataSeries.visible = false;
}
else {
e.dataSeries.visible = true;
}
chart.render();
}
}
});

chart.render();

}

2 – ajax function

function function1(tab){
return $.ajax({
type: ‘POST’,
url: ‘php/load.php’,
dataType: ‘json’,
data: ‘projet=’+ tab,
error: function(){
alert(‘impossible de chercher ce project’);
},
success: function(json){}
});
}

3 – the data construction function in JSON format

function getConsolidation(){
var results = [];
var list = [“SFR” , “MANAGEMENT”];
for(f in list){
results.push(function1(list[f]));
}
$.when.apply(this , results).done(function() {
var table = [];
var values = “”;
for (var i = 0; i < list.length; i++) {
values += ‘”type” : “line”, “showInLegend” : “true”, “name” : “‘+ list[i] +'” ,”dataPoints” : ‘+ results[i].responseText +’,’;
}
//for (var i=0; i<values.length; i++) {
console.log(values);
displayChart(values);
//}

//displayChart(values);
//values.replace(/(\s+)?.$/, ”);// Pour supprimer ‘,’ a la fin de la chaine
});
}

and this is JSON :

[{“type” : “line”, “showInLegend” : “true”, “name” : “name1″ ,”dataPoints” : [{“x”:”2015-3-01″,”y”:34},{“x”:”2015-4-01″,”y”:41},{“x”:”2015-5-01″,”y”:23.800000026822}]
,”type” : “line”, “showInLegend” : “true”, “name” : “name2″ ,”dataPoints” : [{“x”:”2015-2-01″,”y”:14},{“x”:”2015-3-01″,”y”:37},{“x”:”2015-4-01″,”y”:39.20000000298},{“x”:”2015-5-01″,”y”:50.10000000149}]
}]

and of course once again it does not work with any error HELP ME
