Graph with raw data points for four groups in three treatments

I need matlab code to make a graph that displays my raw data points not just the averages. There are four groups ( A, B C and D) and each group has three treatments (high, middle, and low). I need the data for each group to be overlayed for each treatment but have the data with different colors or shapes so A is distinguishable from B etc. high middle and low need to be the x axis and the y axis is numerical (0-140). Thanks in advance for any help!
