[已解决]pygal数据可视化求助！

姬姬西

请问 可视化的数据中有表情符号导致NO data怎么办？按网上的方法还是不行。。。
import sys
non_bmp_map = dict.fromkeys(range(0x10000, sys.maxunicode + 1), 0xfffd)
这个方法试过了 也是NO data

你的字典数据错误 跟图表的数据项匹配不上 应该是不满足style的条件 再加一项就可以了

1. import requests
   
2. import pygal
   
3. from pygal.style import LightColorizedStyle as LCS, LightenStyle as LS
   
4. url = "https://api.github.com/search/repositories?q=language:python&sort=stars"
   
5. r = requests.get(url)
   
6. print("Status code", r.status_code)
   
7. res_dict = r.json()
   
8. print("Total repos", res_dict["total_count"])
   
9. 
   
10. items = res_dict["items"]
    
11. 
    
12. names, plot_dicts = [], []
    
13. 
    
14. for item in items:
    
15.     names.append(item["name"])
    
16.     plot_dict = {
    
17.         "value": item["stargazers_count"],
    
18.         "lavel": item["description"],
    
19.         "xlink": item["html_url"],
    
20.         #"ntm": str(item["description"]) if item["description"] else "Nothing",
    
21.         }
    
22.     # if "Requests" in plot_dict["ntm"]:
    
23.     #     plot_dict["ntm"] = "fuck"
    
24.     plot_dicts.append(plot_dict)
    
25. my_style = LS('#333366', base_style=LCS)
    
26. my_config = pygal.Config()
    
27. my_config.x_label_rotation = 45

32. my_config.truncate_label = 15
    
33. my_config.show_y_guides = False
    
34. my_config.width = 1000
    
35. 
    
36. chart = pygal.Bar(my_config, style=my_style)
    
37. chart.title = "Most-Starred Python Projects on GitHub"
    
38. chart.x_labels = names
    
39. chart.y_label = range(0, 55000, 5000)
    
40. chart.add("", plot_dicts)
    
41. chart.render_to_file("python_repos.svg")
    
42. print(plot_dicts)

也有可能不是那个的原因，我把'ntm':repo_dict['description']删了还是NO data
