Graphs

The first thing that you need to know about graphs is how to name the axes. the x axis is horizontal and the y axis is vertical. You may want to draw a graph that includes negative numbers, in which case the graph does not look like an 'L' but looks like a '+'.

The next thing to decide is what goes on the x axis and what goes on the y axis. Partly this is personal preference but there is a common convention that for bar charts the bars are vertical. That is the way we tend to see columns. We don't tend to see unsupported horizontal structures but there is nothing wrong with the second method.

Finally for now, you have to think about is how to make your graph look neat. How do you make the information that you have fit nicely within the graph. Well the answer is all about scale. If you are looking at 10 items for the x axis then you need space for 10. If you are looking at 100 then you need space for 100.

That sums it up.
