Why can you help me look at the code error, error is this line "line_chart. X_labels=x_unique", is wrong type attributeerror: 'STR' object has no attribute 'x_labels,

The import json
The import math
The import pygal
# to load data into a list
Filename='btc_close_2018. Json'
With the open (filename) as f:
btc_data=https://bbs.csdn.net/topics/json.load (f)

# to create five list, storage date and the closing price
Dates=[]
Up=[]
Weekes=[]
Weekdays=[]
The close=[]

Every day # traversal information
For btc_dict btc_data in:
Dates. Append (btc_dict [' date '])
Have append (int (btc_dict [' month ']))
Weekes. Append (int (btc_dict [' week ']))
Weekdays. Append (btc_dict [' weekday '])
Close. Append (int (float (btc_dict [' close '])))

The from itertools import groupby

Def draw_line (x_data y_data, title, y_legend) :

For x, y in groupby (sorted (zip (x_data y_data)), key=lambda _ : _ [0]) :

Line_chart=pygal. Line ()
Line_chart=title
Line_chart. X_labels=x_unique

Return line_chart

In this line of code: line_chart x_labels=x_unique
Is your x_unique plastic tuple
The plastic tuples into type String list
Then assigned to line_chart. X_labels was no problem ~
Line_chart. X_labels=STR (x_unique)
