for the y axis could you make it go up by $0,10,20,30,40,50,$ and could you make the blue and orange circles a bit more spread out around the graph. When i use this code i keep getting the graph that you see in the picture $,$ everything is fine i just nees the y axis to go up by $10$s starting at $0$ and ending at $50.$ And i need the blue and orange circles to be more spread out. Just fix those two things do not change anything else.

Here is the code to use on matlab :
