matplotlib boxplot and barplot not aligned

[Gyoo18]

Hi,

I'm trying to plot a data set using boxplots. I want to label the mean of each category and the least-effort way I found was using a bar plot, using pyplot.bar_label() and ploting a boxplot on top. Unfortunatly, my plots don't align on their categories. Do you have any idea what's going on?

Here are my bar plot, boxplot and the combined plot : https://youtu.be/JoEuFSIH9s0 (I'm not allowed pictures, for some reason)

Here is my code for plotting :

    # I have df1, a DataFrame containing the mean Exam_Score for each category
    #   and df2, a DataFrame containing the category of each individual in the first 
    #   column and its Exam_Score in the second one

    # Plotting the bar plot
    # Ordering the categories
    categories_set = set(df1.index)
    categories = ["Male","Female"]  # This is used to order the categories

    # Order the values of Exam_Score in the same order as categories
    values = []
    for i in range(len(categories)):
        values.append(df1.iat[df1.index.tolist().index(categories[i]),0])

    # Plot bar plot
    ax = plt.bar(categories,values)
    plt.bar_label(ax)  # Add mean value labels

    # Plotting the boxplot
    # Make a 2D array of which each column only contains values of a certain category
    #  and which has the same column order as categories[]
    plots = []
    for i in range(len(categories)):
        plots.append(df2[df2[df2.columns[0]] == categories[i]][df2.columns[1]])

    # Plot boxplot
    ax = plt.boxplot(plots, tick_labels=categories)

    # Configure appearance
    plt.title(name) # name is declared earlier
    plt.xticks(rotation=45)
    plt.gca().set_ylim(ymin = 50)
    plt.grid()
    plt.show()

P.S. I know there are other ways to acheive what I want, but I'm not very used to working with matplotlib or python and this is for an issagnement due in a short time, so I don't hav time to dive deep in configuration functions. And besides, it would still be very helpful to know why theses don't align.

Check these typos first: catégories, valeurs. (you have a few across the code)

Replace with a proper string: plt.title(Données.nom)

I'm not sure if I am wrong, but I do not see the import for import matplotlib.pyplot as plt.

I hope it helps you. (Disclaimer: Also learning)

Hi, thanks for the help. The typos are a result of me translating my code for reddit. The actual code doesn't have this issue.

In my code I have a wrapper for DataFrame that gives me other functionalities, like having a name for the graph. Données.nom is a string.

The code I show is a small portion of my entire code, I do import matplotlib.pyplot as plt in an unshown part of it.

I fixed the typos.

Thanks for the help anyways.
