谷歌圖表 - 避免在Y軸

Question

負值我有以下代碼：

function drawVisualization() { 
    // Create and populate the data table. 
    var data = google.visualization.arrayToDataTable([ 
    ['Year', 'People'], 
    ['2010',0] 
    ]); 

    // 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"}, 
      backgroundColor: 'none' 
      } 
    ); 
} 

這給了我下面的圖表

我該怎麼做才能避免顯示在Y軸負值？我已經嘗試加入 vAxis: {minValue:0}沒有任何運氣。

Answer 1

您需要設置viewWindowMode爲明確

vAxis: {viewWindowMode: "explicit", viewWindow:{ min: 0 }} 

Answer 2

viewWindowMode: "explicit"在目前的版本已經過時，它使用：vaxis.viewWindow.min：

vAxis: { 
    viewWindow: { 
     min: 0 
    } 
}
