Bohek plot line

I tried to write these codes to display the dataseries plot, but no data was not displayed. I dont know where is the problem exactly.

data=pd.read_csv('weather.csv')[['STA','Date','Precip','MaxTemp','MinTemp','MeanTemp','Snowfall']].dropna()
data = data[data['Precip'] != 'T']
data['Precip'].astype(float)
data['STA']=data['STA'].astype("string")
data['Date']=pd.to_datetime(data['Date'])
stations=list(set(data['STA']))
stations.sort()
select_inital=select.value
colors = list(Category20_16)
colors.sort()
subset=data[data['STA']==select_inital]
initial_values= list(set(subset['STA']))
for i, j in enumerate(initial_values):
   subset=data[data['STA']==j]
   d=subset[['Date','Precip']]
   d.sort_values('Date')
   x=d['Date']
   y=d['Precip']
   d = ColumnDataSource(d)

p = figure(plot_width=700, plot_height=700, x_range=(0,200), title='Weather      Evolution',x_axis_label='Date', y_axis_label='Precip',x_axis_type='datetime')
p.line(x,y, legend_label="Evolution", line_width=2开发者_开发百科)
show(p)

This is just guessing but I believe the problem is, that you are trying to set limits to the x_range. Bokeh is evalutating dates as milliseconds and your x_range=(0,200) is also interpreted as millisecond. This means the visible ares is very small. You could use the defaults by bokeh insted.

Minimal example

This is working. This is your code for the figure except I removed the x_range.

import pandas as pd
from bokeh.plotting import figure, show, output_notebook
output_notebook()

x = pd.date_range('2022-12-01', '2022-12-24', freq='D')
y = list(range(1,25))

p = figure(
    plot_width=700,
    plot_height=700,
    # x_range=(0,200),
    title='Weather      Evolution',
    x_axis_label='Date',
    y_axis_label='Precip',
    x_axis_type='datetime'
)
p.line(x,y, legend_label="Evolution", line_width=2)
show(p)

Bokeh default x_range	x_range by user
