Question

我试图使用散景绘制折线图，但得到奇怪的图表。我对散景库没有太多经验。我创建了ColumnDataSource并将其传递给了图。以下是我的源数据。

{'x': [datetime.date(2017, 8, 8),
  datetime.date(2017, 8, 9),

 Name: num_of_times_booked, dtype: float64}

以及绘制图表的代码如下。

po = figure(title='Portland booking data', y_axis_label='Num of time Booked', x_axis_label='Time', x_axis_type="datetime", plot_width=800)
po.line(x='x', y='y', source=source_2)
po.circle(x='x', y='y', source=source_2)
show(po)

当我运行上面的代码时，我得到下面的图表。

为什么线相互交叉。我犯了什么错误吗？

Answer 1

哎呀我的错误日期没有在源中排序

散景线图未按预期工作
