面积图 - 从非零 y 值开始填充

Area chart - start filling from non zero y value

我正在尝试创建一个面积图,在我使用条形图的地方看起来像这样:

 var trace1 = {
  x: ['2013-10-04 9:00:00', '2013-10-04 9:30:00', '2013-10-04 10:00:00', '2013-10-04 11:00:00', '2013-10-04 11:30:00', '2013-10-04 12:30:00'], 
  y: [20, 20, 10, 10, 20, 20], 
  type: 'bar',
  base: [5,5,5,5,5,5],
  mode: 'none'
};
var data = [trace1];
myDiv = document.getElementById('myDiv');
Plotly.newPlot(myDiv, data);

Pen

如您所见,y 轴从非零值开始。有可能吗?

谢谢

您可以添加此代码以开始 y 轴 0

var layout = {
  yaxis: {
    rangemode: 'tozero' //or below
    //range: [0, 25]
}
};

Plotly.newPlot(myDiv, data, layout);
