我的图表在其数据更新时以及将图表下载到客户端时冻结。以下是我的更新过程。
FusionCharts.setCurrentRenderer('JavaScript');
FusionCharts.ready(function () {
var chart = new FusionCharts({
type: "dragcolumn2d",
renderAt: "chartWeightAnalysis",
id: "dragChartId",
width: '100%',
height: '500',
dataSource: "compute/" +<?php echo $_SESSION['MM_Username']; ?> + "renderChartDragColumn2d.xml",
dataFormat: "xmlurl",
events: {
'chartUpdated': function (evt, args) {
var diffWeight = args.startValue - args.endValue;
var resultXML = chart.getXMLData();
var result = JSON.stringify(chart.getData());// alert(chart.getData());
var newString = jQuery.parseJSON(result);
var weightBox = [];
var sum = 0;
var resultBox = [];
var allDataBox = [];
jQuery.each(newString, function (key, value) {
if (key !== 0 && key !== args.dataIndex) {
weightBox.push(value[1]);
sum += value[1];
}
});
for (var key in weightBox)
{
var ratio = (weightBox[key] * diffWeight / sum);
var newValue = ratio + weightBox[key];
resultBox.push(newValue);
allDataBox.push(weightBox[key], newValue);
}
var dataIndex = (args.dataIndex - 1) * 2;
allDataBox.splice(dataIndex, 0, args.startValue, args.endValue);
var matrix = listToMatrix(allDataBox, 2);
for (var key in matrix) {
resultXML = resultXML.replace('value="' + matrix[key][0] + '"', 'value="' + matrix[key][1] + '"');
}
UpdateChart(chart, resultXML);
}
}
}).render();
});
}
function UpdateChart(chart, resultXML) {
chart.setXMLData(resultXML);
}

一旦呈现,它就会变得没有反应。可能是什么问题? 同时将图表导出到客户端会导致它同样冻结。
答案 0 :(得分:2)
我找到了答案,我意识到错误来自setChartData函数,如果你使用不同的 setChartData 类型,它会变得无法响应。例如,在我的代码中,我使用 datasouce:作为XML的URL ( setXMLUrl 等价物),后来想要依次使用 setXMLData 进行更新造成了一个错误。查看更新代码;我使用ajax将更新日期保存到 相同文件 (重要!!!)。
function UpdateChart(resultXML) {
$.ajax({
type: "POST",
async: false,
url: "app_processor.php",
data: {action: "DragChartUpdate", getXMLData: resultXML},
success: function (msg) {
if (msg !== 0)
{
chart.setXMLUrl("compute/" +<?php echo $_SESSION['MM_Username']; ?> + "renderChartColumn2d.xml");
}
}
});
}
在我的php文件中:
function DragChartUpdate($getXMLData) {
if (isset($getXMLData)) {
file_put_contents("compute/" . $_SESSION['MM_Username'] . "renderChartColumn2d.xml", "<?xml version='1.0' encoding='utf-8'?>" . $getXMLData . "");
} else {
file_put_contents("compute/" . $_SESSION['MM_Username'] . "renderChartColumn2d.xml", "<?xml version='1.0' encoding='utf-8'?>");
}
}
