1. The problem statement, all variables and given/known data Hi, this isn't really a homework assignment but just a question that will help with some of my homeworks I do get given. I am struggling with understanding about where to start graphs on the x-axis. If I plot a graph where I have the values 90,100,110,120,130 and 140 on the x axis then if I start at zero on the x-axis my graph ends up on one side. 2. Relevant equations None 3. The attempt at a solution There are two ways I know of to go about correcting this but have no idea which one to use and why there are two! First method - start the x axis at 90 (i.e. where it would normally be x=0) since this is my first data point. Second method - start the x-axis at x=0 then draw a little squiggly line thing (no idea what they are called) and then start at 90 after the squiggly line. From looking around online a lot of people seem to do the squiggly line thing but I have no idea why because why would you ever do method 2 when you could do method one? Method two seems pointless and a waste of space on the graph when you can just start your graph at 90 or am I missing something? Which one should I use?
