Feedback for the Course Project 1

Hi, 
In order to give you a useful feedback, I saw the following issues:
- You didn't save the plots as is required in the assessment: "Construct the plot and save it to a PNG file with a width of 480 pixels and a height of 480 pixels."
- Your legends for plot 3 and plot 4 are wrong, since they have lines not points.
- For plot 4, you forgot to remove the box around the legend.  
- I didn't penalize the color background, but the Instructor's plots are transparent.
Best regards,
Stagirite
