Why date in x label does not match with it's bar chart?


I am trying to make bar chart with x axis is date and y axis is total sales.

Here is the code:

import pandas as pd
import plotly.express as px

df = pd.read_csv("data-sales.csv")
fig = px.bar(data_frame=df, x="Basedate", y="Sales")

Here is the result:

Here is the data:


The data above is from dummy database that created myself and then I download it as csv file, but if I create exactly the same data manually in excel, the result is different.

What’s wrong with the data from the database?
