- Drawing line graphs
Information is all around us. Whether in words or in numbers,
it comes at us from the news, from the internet, from our
studies, and from conversations. Having all the facts is a good
thing, but only if you can make sense of all of it. One of the
ways to help us make sense of all the information coming at
us is to represent it in a well-designed chart or graph. Visual
representations of data are often easier to understand than
tables full of numbers.
In this chapter, you’ll look at those charts and graphs from
both sides. One of the most useful skills you can have is the
ability to read a graph and pull the important information
from it. Knowing what distinguishes a good graph from a not
so good one is important, too. Sometimes the responsibility is
on you to produce a graph, and whether you do that by hand
or with the help of a computer, you need to know how to do it
correctly. This chapter will look at several different types of
graphs, how to read them, how to make them, and what kinds
of information they best represent.
