问题描述
我如何可以检索和使用数据集的谷歌图表,如果它是一个独立的JSON文件?我试过的jQuery的getJSON但无法得到它的工作..谷歌的Viz应该使用JSON绘制条形图是否有原生的谷歌API的方式?或者我能找到使用jQuery以及如何呀?谢谢
//将可视化的API和饼图包。
google.load('可视化','1.0',{'包':'corechart']});
//设置一个回调,当谷歌可视化的API被加载运行。
google.setOnLoadCallback(drawChart);
//回调创建并填充数据表,
//实例化的饼图,传递数据和
//绘制它。
功能drawChart(){
//创建的数据表。
VAR数据=新google.visualization.DataTable();
data.addColumn('串','产品');
data.addColumn('编号','自动');
data.addRows([
['产品1',85],
[产品2,75],
['产品3',90]
['产品4',40],
['产品5',40]
]);
//设置图表选项
VAR pie_options = {'标题':'多少自动我们的产品?,
宽:520,高度:300
};
VAR bar_options = {'宽度':620,高度:300,
'标题':'产品',
hAxis:{'标题':'%自动化','titleTextStyle:{颜色:红色,fontSize的:16}}
}
//实例化和绘制我们的图表,传递一些选项。
VAR图=新google.visualization.PieChart(的document.getElementById('piechart_div'));
chart.draw(数据,pie_options);
VAR图=新google.visualization.ColumnChart(的document.getElementById('barchart_div'));
chart.draw(数据,bar_options);
}
新google.visualization.DataTable(JSON)
和
看的输出<一个href="https://$c$c.google.com/apis/chart/interactive/docs/reference.html#DataTable"><$c$c>dataTable.toJSON()为正确的结构来使用。
所以,如果你有你的服务器上getjson.php脚本返回格式正确的JSON,你可以这样做:
$。的getJSON('/ getjson.php',函数(JSON){
VAR的dataTable =新google.visualization.DataTable(JSON);
});
How can I retrieve and use a dataset for google charts if it was a separate JSON file?? I tried jQuery getJSON but couldn't get it worked.. Google Viz should use the JSON to draw a bar chartIs there a native google API way? or can I find a way using jQuery and how?Thanks
// Load the Visualization API and the piechart package.
google.load('visualization', '1.0', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawChart);
// Callback that creates and populates a data table,
// instantiates the pie chart, passes in the data and
// draws it.
function drawChart() {
// Create the data table.
var data = new google.visualization.DataTable();
data.addColumn('string', 'Products');
data.addColumn('number', 'Automated');
data.addRows([
['Product 1', 85],
['Product 2', 75],
['Product 3', 90],
['Product 4', 40],
['Product 5', 40]
]);
// Set chart options
var pie_options = {'title':'How Much Automated our Products are?',
'width':520,'height':300
};
var bar_options ={'width': 620, 'height': 300,
'title': 'Products',
'hAxis': {'title': '% Automated', 'titleTextStyle': {'color': 'red', 'fontSize': 16}}
}
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.PieChart(document.getElementById('piechart_div'));
chart.draw(data, pie_options);
var chart = new google.visualization.ColumnChart(document.getElementById('barchart_div'));
chart.draw(data, bar_options);
}
new google.visualization.DataTable(json)
works.
Look the output of dataTable.toJSON()
for the correct structure to use.
So, if you have a getjson.php script on your server that returns correctly formatted json, you could do that:
$.getJSON('/getjson.php', function(json) {
var dataTable = new google.visualization.DataTable(json);
});
