I can't change the border color even though I declared it as black.

fig=plt.figure(figsize=(25, 10), tight_layout = True, edgecolor = 'black')
plt.title('Distribution of Item Type')
plt.xlabel('Item Type')


plt.hist(BigMart_Data_Encoded['Item_Type'],bins = 15)

Try defining the edgecolor parameter inside the .hist() function instead of figure:

fig=plt.figure(figsize=(25, 10), tight_layout = True)
plt.title('Distribution of Item Type')
plt.xlabel('Item Type')


plt.hist(BigMart_Data_Encoded['Item_Type'],bins=15, edgecolor='black')
