Google图表 - 避免在yAxis中显示负值

Question

我有以下代码:

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'
           }
      );
}

这给了我以下图表

如何避免在yAxis中显示负值？我试过添加 vAxis: {minValue:0}没有任何运气.

Answer 1

您需要将viewWindowMode设置为显式

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

Answer 2

viewWindowMode: "explicit"在当前版本中已弃用，它使用vAxis.viewWindow.min：

vAxis: {
    viewWindow: {
        min: 0
    }
}
