So when I finished this project, I checked the solution video and found that I hadn’t quite done it right. Step 6 says “You are going to create a bar chart visualizing how many goals were scored each year the World Cup was held between 1930-2014.” I took ‘how many goals were scored each year’ to indicate that they wanted a total of goals for each year. So I used
ax = sns.barplot(data = df, x = ‘Year’, y = ‘Total_Goals’, estimator = sum, ci=None)
I changed the estimator to sum to get the goal totals and got rid of the error bars since sums don’t create error. Apparently, the project actually wanted the averages to be graphed. I realize that average is the default estimator for the barplot function, but thought using a different estimator might be part of the challenge.
So just in case anyone else found that confusing or misleading, I thought I’d post about it.
