谷歌圖表錯誤？軸未從0開始

Question

下面的例子是谷歌創建一個使用谷歌圖表一的ColumnChart

function drawVisualization() { 
// Create and populate the data table. 
var data = google.visualization.arrayToDataTable([ 
['Year', 'Austria', 'Belgium', 'Czech Republic', 'Finland', 'France', 'Germany'], 
['2003', 1336060, 3817614,  974066,  1104797, 6651824, 15727003], 
['2004', 1538156, 3968305,  928875,  1151983, 5940129, 17356071], 
['2005', 1576579, 4063225,  1063414,  1156441, 5714009, 16716049], 
['2006', 1600652, 4604684,  940478,  1167979, 6190532, 18542843], 
['2007', 1968113, 4013653,  1037079,  1207029, 6420270, 19564053], 
['2008', 1901067, 6792087,  1037327,  1284795, 6240921, 19830493] 
]); 

// Create and draw the visualization. 
new google.visualization.ColumnChart(document.getElementById('visualization')). 
    draw(data, 
     {title:"Yearly Coffee Consumption by Country", 
     width:600, height:400, 
     hAxis: {title: "Year"}} 
); 
} 

這完美的作品，但是，我只希望每列的值，所以我將其更改爲：

function drawVisualization() { 
// Create and populate the data table. 
var data = google.visualization.arrayToDataTable([ 
['Month', 'How many'], 
['07', 193], 
['08', 114], 
['09', 158] 
]); 

// Create and draw the visualization. 
new google.visualization.ColumnChart(document.getElementById('visualization')). 
    draw(data, 
     {title:"Yearly Coffee Consumption by Country", 
     width:600, height:400, 
     hAxis: {title: "Year"}} 
); 
} 

現在垂直軸不是從0開始，而是接近最低值，在這種情況下是114 - 這是一個錯誤嗎？我仍然希望它顯示從0，因爲它很容易混淆像這樣快速瀏覽

任何想法？

Answer 1

繪製圖表時，需要將另一個參數作爲選項的一部分。

vAxis: {minValue: 0} 

這將迫使垂直軸從0開始，你可以在這裏看到其他可能的選項：https://google-developers.appspot.com/chart/interactive/docs/gallery/columnchart#Configuration_Options

Answer 2

如果你有在圖形vAxis: {minValue: 0}不是數據也無濟於事。所以，你可以使用配置選項viewWindow：

var options = { 
    vAxis: { 
     viewWindow: { 
      min:0 
     } 
    } 
}; 
var chart = new google.visualization.ComboChart(document.getElementById('chart_div')); 
chart.draw(dataTable, options);
