我正在使用Google chart tool來編寫條形圖。我的數據在哪裏?
這裏是我的代碼:
function drawBar(){
var data2 = new google.visualization.DataTable();
data2.addColumn('string', 'Project');
data2.addColumn('number', '2011 Fiscal Spending');
data2.addRows(5);
// Gather Data
$.getJSON("/Organizations/TopFiveSpending",{orgName : "Office of Technology"},function(data){
$(data).each(function(i,e){
//data2 is populating fine here when i debug
data2.setValue(i,0,e.ProjectName);
data2.setValue(i,1,e.TotalFYSpending);
})
});
barGraph = new google.visualization.ColumnChart(document.getElementById('portfolio-total-spending'));
var options = {width: 250, height: 190, legend: 'none',
hAxis: {title: 'Project', titleTextStyle: {color: 'red'}}
};
//data2 has null data here
barGraph.draw(data2,options);
google.visualization.events.addListener(barGraph, 'onmouseover', function(e) {
console.log('barGraph hover '+e['row']);
table.setSelection([{row:e['row']}]);
});
}
我的圖表繪製從來沒有任何東西,我不會在我的控制檯得到任何錯誤。當我調試代碼時,我不是那個data2
正在填充正確的數據。但是,當調用barGraph.draw()
函數時,數據不見了。我在代碼中發表了這方面的評論。任何想法如何解決這個問題?
看起來像這樣做。謝謝! – ZeroDivide
