設置查詢範圍谷歌圖表

Question

我將如何去定義我希望我的圖表從中獲取數據的範圍。使用這個例子我在哪裏設置查詢範圍？我想開始建立一些圖表鏈接到我的電子表格數據的網頁。謝謝！

google.load("visualization", "1", {packages:["corechart"]}); 

function initialize() { 
    var opts = {sendMethod: 'auto'}; 
    // Replace the data source URL on next line with your data source URL. 
    var query = new google.visualization.Query('http://spreadsheets.google.com/tq?key=0AnD0SFr9ooPgdG83Wm&transpose=0&headers=1&merge=COLS&range=A1%3AA5%2CB1%3AC5&gid=0&pub=1', opts);   
    - 
    // Optional request to return only column C and the sum of column B, grouped by C members. 
    //query.setQuery('select C, sum(B) group by C'); 

    // Send the query with a callback function. 
    query.send(handleQueryResponse); 
} 

function handleQueryResponse(response) { 
    if (response.isError()) { 
    alert('Error in query: ' + response.getMessage() + ' ' + response.getDetailedMessage()); 
    return; 
    } 

var data = response.getDataTable(); 

var options = { 
title: 'Company Performance' 
}; 

var chart = new google.visualization.LineChart(document.getElementById('chart_div')); 
chart.draw(data, options); 
} 

    google.setOnLoadCallback(initialize); 

Answer 1

您可以選擇在查詢（通過setQuery方法）的列和過濾條件，也可以在URL的range參數中指定的片材範圍。 ！

// use setQuery 
var query = new google.visualization.Query('http://spreadsheets.google.com/tq?key=0AnD0SFr9ooPgdG83Wm&transpose=0&headers=1&merge=COLS&gid=0&pub=1', opts); 
query.setQuery('select a, b, c where d < 7'); 

或

// set range to A1:C10 
var query = new google.visualization.Query('http://spreadsheets.google.com/tq?key=0AnD0SFr9ooPgdG83Wm&transpose=0&headers=1&merge=COLS&gid=0&pub=1&range=A1:C10', opts);
