Question

我无法让Bokeh显示我的情节。这是我的Python代码。

我检查了我的Chrome浏览器Inspect Element，控制台显示以下内容。

赢得Seasons.html：17 [散景]无法设置初始范围 e.set_initial_range @Winsins对齐Seasons.html：17

这似乎只是在我从文件中读取时发生的。硬编码x和y坐标有效。

我检查了其他帖子，但没有一个修复工作。我的所有套餐都是最新的。

这是我正在阅读的文件

import pandas as pd
from bokeh.plotting import figure, ColumnDataSource
from bokeh.io import output_file, show


if __name__ == '__main__':
    file = 'Overview Data.csv'
    overview_df = pd.read_csv(file)
    overview_ds = ColumnDataSource(overview_df)
    output_file('Wins across Seasons.html')
    print(overview_ds.data)
    p = figure(plot_width=400, plot_height=400)

    # add a circle renderer with a size, color, and alpha
    p.circle('Season', 'Wins', source = overview_ds, size=20, color="navy", alpha=0.5)

    # show the results
    show(p)

这是print语句的输出。

Answer 1

除非你告诉它，否则Bokeh不知道如何处理这些字符串日期。有两种基本的可能性：

将它们保留为字符串，并将它们视为分类因素。您可以通过告诉Bokeh创建绘图时的因素来做到这一点：
```
p = figure(plot_width=400, plot_height=400, 
           x_range=list(overview_df.Season.unique()))
```
这导致了这个数字：

如果您想要不同类别的订单，可以根据需要重新订购x_range。
将它们转换为实际日期时间值并使用datetime轴。您可以通过告诉Pandas将第0列解析为日期字段来执行此操作：
```
overview_df = pd.read_csv(file, parse_dates=[0])
```
告诉Bokeh使用日期时间轴：
```
p = figure(plot_width=400, plot_height=400, x_axis_type="datetime")
```
这导致了这个数字：

Answer 2

您可以将“季节”列转换为日期时间以获得输出。

overview_df = pd.read_csv(file)
overview_df.Season = pd.to_datetime(overview_df.Season)
overview_ds = ColumnDataSource(overview_df)
