python - 在 map Bokeh 上执行面积图时，它显示空白框并且不起作用

Question

我试图绘制特定地铁站每天的出行率。我尝试使用 Bokeh 来绘制它。当我使用 Bokeh 示例数据时，它工作正常，但是，当我传递必须为其绘制 Bokeh 的数据时，它会显示空白的 Bokeh 图。

我正在使用以下代码:

from bokeh.io import show
from bokeh.models import (
    ColumnDataSource,
    HoverTool,
    LogColorMapper
)
from bokeh.palettes import Viridis6 as palette
from bokeh.plotting import figure

palette.reverse()

county_xs = stop_frame['latitude'].tolist()
county_ys = stop_frame['longitude'].tolist()

county_names = stop_frame['stop_name'].tolist()
county_rates = stop_frame['Rate'].tolist()
color_mapper = LogColorMapper(palette=palette)

source = ColumnDataSource(data=dict(
    x=county_xs,
    y=county_ys,
    name=county_names,
    rate=county_rates,
))

TOOLS = "pan,wheel_zoom,reset,hover,save"

p = figure(
    title="Busy Stops of MBTA", tools=TOOLS,
    x_axis_location=None, y_axis_location=None
)
p.grid.grid_line_color = 'Red'

p.patches('x', 'y', source=source,
          fill_color={'field': 'rate', 'transform': color_mapper},
          fill_alpha=0.7, line_color="black", line_width=0.5)

hover = p.select_one(HoverTool)
hover.point_policy = "follow_mouse"
hover.tooltips = [
    ("Stop Name", "@name"),
    ("Number", "@rate%"),
    ("(Long, Lat)", "($x, $y)"),
]

show(p)

This is the plot I got I want plot like this

我在绘图中使用以下数据:

请建议我如何查看正确的 Bokeh 图

Answer 1

尝试运行您的示例时我注意到两个问题:

1. 尝试绘制缺失值时会出现错误，要消除它们，您可以使用

   stop_frame.dropna(inplace=True)
   

   或者使用一些合理的默认值填充它们

   stop_frame.fillna(0, inplace=True)
   

2. 您的纬度和经度坐标只是标量值。在 texas示例(您正在修改)lats 和 longs由定义县边界的 float 列表组成。

   因此，尝试使用 patches(需要列表列表)会抛出JS 控制台中的错误无法设置初始范围...

   将其修正为patch仍然无法填充面部在

   中的 fill_color 选项中传递一个字典

   p.patch('x', 'y', source=source,
           fill_color={'field': 'rate', 'transform': color_mapper},
           fill_alpha=0.7, line_color="black", line_width=0.5)
   

   将其更改为 fill_color='blue' 将绘制线条连接您的站点。

   更好的解决方案是使用scatter或circle，即

   p.circle('x', 'y', source=source,
            fill_color={'field': 'rate', 'transform': color_mapper}, 
            fill_alpha=0.7, line_color= 'black', line_width=0.5) 
   

   更好的是，您可以使用速率的对数来缩放圆半径(或其他一些功能)

   source = ColumnDataSource(data=dict(
       x=county_xs,
       y=county_ys,
       name=county_names,
       rate=county_rates,
       log_rate=np.log(county_rates),
   ))
   
   ...
   
   p.circle('x', 'y', source=source,
            radius='log_rate',
            fill_color={'field': 'rate', 'transform': color_mapper}, 
            fill_alpha=0.7, line_color= 'black', line_width=0.5) 
   

编辑:回答评论中的问题。您可以通过修改德克萨斯州的示例来绘制马萨诸塞州的县。您可以在绘制止损点之前轻松插入这段代码。

from bokeh.sampledata.us_counties import data as counties

ma_counties = {
    code: county for code, county in counties.items() if county["state"] == "ma"
}

ma_county_xs = [county["lats"] for county in ma_counties.values()]
ma_county_ys = [county["lons"] for county in ma_counties.values()]
ma_county_names = [county['name'] for county in ma_counties.values()]

ma_source = ColumnDataSource(data=dict(
    x=ma_county_xs,
    y=ma_county_ys,
    name=ma_county_names
))

p.patches('x', 'y', source=ma_source,
         fill_color='gray', 
         fill_alpha=0.7, line_color= 'black', line_width=0.5)

注意:根据您的设置，您需要放大才能查看 map ，因为您的列表中几乎没有异常站点。
