Make Upload and Download bars different colors.
Both are currently Red. Please pick different colors for Upload and Download. Like one is red the other is green.

Because the two different shades of blue being used in the graph, it is hard to see what is downloaded and what is being uploaded. Please use clearly different colors. May I suggest green for downloading, since we are almost always sure what is being downloaded, and red for uploading, since uploading may be caused by malicious software?
