Hi I am trying to plot a scattered line graph that contains nearly 4000 points on the y axis. The points represent a day. The x axis is the percentage belonging to that day. The problem that I am having is that the graph looks squashed together and the line is very thick because of this. One of the reasons for this is that a lot of the 4000 points have similar percentages so the line just moves a tiny bit. Is there a way that I can make the graph look more presentable? Thanks

The following is a picture of how it looks. You may need to enlarge it to see it properly.
