directory of data.php

i prepared a chart for gather data from mysql database table and paste javascript code in javascript space ‘AmCharts.loadJSON = function(url) {
// create the request
if (window.XMLHttpRequest) {
// IE7+, Firefox, Chrome, Opera, Safari
var request = new XMLHttpRequest();
} else {
// code for IE6, IE5
var request = new ActiveXObject(‘Microsoft.XMLHTTP’);
}

// load it
// the last “false” parameter ensures that our code will wait before the
// data is loaded
request.open(‘GET’, url, false);
request.send();

// parse adn return the output
return eval(request.responseText);
};

AmCharts.ready(function() {
// load the data
var chartData = AmCharts.loadJSON(‘data.php’);

// this is a temporary line to verify if the data is loaded and parsed correctly
// please note, that console.debug will work on Safari/Chrome only
console.debug(chartData);

// build the chart
// …
});

var %CHART%;

// create chart
AmCharts.ready(function() {

// load the data
var chartData = AmCharts.loadJSON(‘data.php’);

// SERIAL CHART
chart = new AmCharts.AmSerialChart();
chart.pathToImages = “https://www.amcharts.com/lib/images/”;
chart.dataProvider = chartData;
chart.categoryField = “category”;
chart.dataDateFormat = “YYYY-MM-DD”;

// GRAPHS

var graph1 = new AmCharts.AmGraph();
graph1.valueField = “value1”;
graph1.bullet = “round”;
graph1.bulletBorderColor = “#FFFFFF”;
graph1.bulletBorderThickness = 2;
graph1.lineThickness = 2;
graph1.lineAlpha = 0.5;
chart.addGraph(graph1);

var graph2 = new AmCharts.AmGraph();
graph2.valueField = “value2”;
graph2.bullet = “round”;
graph2.bulletBorderColor = “#FFFFFF”;
graph2.bulletBorderThickness = 2;
graph2.lineThickness = 2;
graph2.lineAlpha = 0.5;
chart.addGraph(graph2);
