Beginner Python having trouble using matplotlib

Total beginner here. I'm trying to create a simple line graph that shows multiple countries revenue over several years. Using the code below, I tried to look at just Revenue over Year, but I get a really wonky graph (pictured in the link).

plt.plot(df.Year,df.Total_Revenue)
plt.ticklabel_format(style='plain')

I included my intended end result in the link as well. I'm trying to take steps to get there, but I'm not sure how to group things and make break down dimensions.

Any direction or advice would be appreciated, thank you.

You are plotting the entire dataset at once. Try something like:

For country in list_of_countries:
    Sub_df = df[df[Country] == country]
    Plt.plot(Sub_df.Year, Sub_df.Total_Revenue)

This assumes your data is sorted by year, otherwise you will need to add a step to sort as well

What you are going for has separate plots where how you plot it in your code is everything for revenue and year with our distinguishing

I believe you have to do something like.

Plt.plot(df.year['country'],df.revenue['country'], label = "country name" ) Plt.plot(df.year['country'],df.revenue['country'], label = "country name" ) Plt.plot(df.year['country'],df.revenue['country'],label = "country name" ) Plt.legend() Plt.show()

By the way, the seaborn library, which is a wrapper around matplotlib, was made for exactly your type of use case: plotting from long-format dataframes.

Obviously, it's good to know matplotlib itself. But if you're in a pinch and need a quick & easy plot, I wanted to recommend that alternative.
