First, we are going to look at the chart called bar_chart.png.
The data you will need to recreate this chart is in the lists past_years_averages, years, and error.
Save your recreated chart to a file called my_bar_chart.png.
Instructions
First, create a figure of width 10 and height 8.
Plot the blue bars, which have the heights listed in past_years_averages.
Add error bars of cap size 5 and heights corresponding to the list error.
Set the axis to go from -0.5 to 6.5 on the x-axis and 70 to 95 on the y-axis.
Create an ax object using plt.subplot(). Use ax to set the x-axis ticks to be range(len(years)) and the x-axis labels to be the years list.
Add the title "Final Exam Averages", x-axis label "Year", and y-axis label "Test average".
Save your figure to a file called my_bar_chart.png.
