Graph Gridlines and Axis Ranges Help

[jennacapra]

I am making a graph in excel and I am wanting the tick lines at the bottom of my chart to be full lines. Is this possible on excel? I am also wanting my y-axis to start at 1 instead of having all of that blank space at the bottom of my graph. I am also wanting to put those lines in there that create a right angle. I have inserted a picture of my current graph and a picture of what I am wanting it to look like in the end. Any help on this will be so greatly appreciated.
