As I was typing some of my data into this reply I realized that maybe it was a function of the wrong dates ( I had not corrected for difference between MatLab and Excel). I fixed this and the dates display properly.
However, now I'm trying to get all of the data points to show up. Currently, only about 4 or 5 out of the 12 data points (ticks) are being displayed. If you would like to comment on this feel free. Otherwise, thanks for you help on the previous question.
