Python chart: Minimum value

[jamescooper]

Not sure why this doesn't work?

import pandas as pd
from datetime import datetime
import matplotlib.pyplot as plt

today_format = datetime.strptime(datetime.today().strftime('%d/%m/%Y'), "%d/%m/%Y")
filtered_df = values=df['Current price'], aggfunc='min') & (df['Date Captured'] == today_format)]
filtered_df.plot(x="Mon Year", y=["Current price"], kind="bar")
plt.title("Minimum Price")
plt.xlabel("Month Year")
plt.ylabel("Price (£)")
plt.locator_params(axis='x', nbins=12)
plt.show()

This is not working as you intended, the df_filtered is only filtering for "Mon Year" = string_date. The first filter gets overridden.

You need both simultaneously like this

df_filtered = df[(df["Date Captured"].dt.date == today) & (df["Mon Year"] == string_date)]

Thanks a lot works brilliant. When I model a graph for average the graph values come out as decimals. How would I round to the nearest integer?

Pretty sure it is on this part I need to modify the code.

fig, ax = plt.subplots()
p1 = ax.bar(grouped["Check-In"], grouped["Current price"], color='#FFA500')
ax.bar_label(p1, label_type="edge")
ax.bar_label(p1)

Many thanks.
