  1. POHow to get chartdata from ajax call into javascript
    primarykey
    data
    text
    <p>I am working with amcharts and i have a file (data.php) that contains some php code used to produce the "var chartdata=[''];" for the chart. It also has the javascript for drawing the chart. It takes 3 variables, user-id, dateStart and dateEnd. I have also this second file (view.php) that has a form which submits its data to the file above via $_GET method. In this file i have a space to draw chart right below the form. </p> <p>What i want to do is for the user to enter user-id, dateStart, dateEnd then submit,, and get the chart shown below the form (in the 'div') the chart should redraw every time user hits submit. For it i thought using jQuery $.ajax but i can't draw the chart. In the specified div, it brings only the "var chartdata=[' all chart data here '];"</p> <p>here is the ajax code in view.php: </p> <pre><code>$.ajax({ type: "GET", url: "data.php", data: {user: $("#user").val(), dtStart: $("[name=dtStart]").val(), dtEnd: $("[name=dtEnd]").val()}, dataType: "html", success: function(data) { $("#chartdiv").html(' '); $("#chartdiv").html(data); } }); </code></pre> <p>and here is the code for drawing the graph: </p> <pre><code>var chart; var average = 90.4; AmCharts.ready(function() { // SERIAL CHART chart = new AmCharts.AmSerialChart(); chart.pathToImages = "http://www.amcharts.com/lib/images/"; chart.autoMarginOffset = 5; chart.marginTop = 0; chart.marginRight = 10; chart.zoomOutButton = { backgroundColor: '#000000', backgroundAlpha: 0.15 }; chart.dataProvider = chartData; chart.categoryField = "date"; // AXES // category var categoryAxis = chart.categoryAxis; categoryAxis.parseDates = true; // as our data is date-based, we set parseDates to true categoryAxis.minPeriod = "mm"; // our data is daily, so we set minPeriod to DD categoryAxis.dashLength = 1; categoryAxis.gridAlpha = 0.15; categoryAxis.axisColor = "#DADADA"; categoryAxis.equalSpacing = false; // value var valueAxis = new AmCharts.ValueAxis(); valueAxis.axisColor = "#DADADA"; valueAxis.dashLength = 1; valueAxis.logarithmic = true; // this line makes axis logarithmic chart.addValueAxis(valueAxis); // GUIDE for average var guide = new AmCharts.Guide(); guide.value = average; guide.lineColor = "#CC0000"; guide.dashLength = 4; guide.label = "average"; guide.inside = true; guide.lineAlpha = 1; valueAxis.addGuide(guide); // GRAPH var graph = new AmCharts.AmGraph(); graph.type = "smoothedLine"; graph.bullet = "round"; graph.bulletColor = "#FFFFFF"; graph.bulletBorderColor = "#00BBCC"; graph.bulletBorderThickness = 1; graph.bulletSize = 1; graph.title = "Price"; graph.valueField = "price"; graph.lineThickness = 2; graph.lineColor = "#00BBCC"; chart.addGraph(graph); // CURSOR var chartCursor = new AmCharts.ChartCursor(); chartCursor.cursorPosition = "mouse"; chartCursor.categoryBalloonDateFormat = "DD MMM, JJ:NN:SS"; chart.addChartCursor(chartCursor); // SCROLLBAR var chartScrollbar = new AmCharts.ChartScrollbar(); chart.addChartScrollbar(chartScrollbar); // WRITE chart.write("chartdiv"); }); &lt;/script&gt; </code></pre> <p>can you give me some help please? I'm unfamiliar with jQuery and i'm trying my best to figure out how to solve this.. Thanks Regards</p>
