Visualize ROI

In the previous chapter, we calculated ROI daily, which will help us recognize the unprofitable day. Indeed, if we know that Monday is unprofitable, we should spend less money to attract users, for example!

It is tough to conclude without graphs, so visualize ROI!

Task

Create barplot with the arguments:

df as the data parameter.
'day' column for x-axis.
'ROI' column for y-axis.

Output barplot

Task

Create barplot with the arguments:

df as the data parameter.
'day' column for x-axis.
'ROI' column for y-axis.

Output barplot

Congratulations! We figured out that Monday and Thursday are the most unprofitable days. Further, it is fantastic to find out whether these two days are similar or if we are making the same mistake on Monday and Thursday. But to do it, you should continue learning courses that will help you to become a Data Analyst.

Everything was clear?
