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 ~

CodePudding user response:

Because of you in the previous month and close into int, prompt int has no len, if not in front of the transformation, there is no problem

I am also a beginner, here is my address code, defines two functions, a data, a drawing, the original poster of the mistakes, mainly because of drawing in the abscissa must be a string, the solution for the following

This is my run results

CodePudding user response:

Thank you, this problem for two days, and finally solved the

CodePudding user response:

And thanks for everyone, for half of the afternoon, finally solved the

CodePudding user response:

Thank you very much!!!!!! I put all function one by one, haven't found the problem, the original is a type of problem,

CodePudding user response:

Thought such broad mistakes can't search the answer on the Internet, search results will search here, thank you all for the great god

Originally there are so many friend in this book, can find the same problem, very helpful, thank you very much!

According to the above the second floor laoge method to change the source code
Line_chart. X_labels=x_unique

-> Line_chart. X_labels=[STR (_) for _ in x_unique]

This compilation type errors will not happen again
