There are three parts to this.

1. Look at the labels of the axis of the graph. Generally these will have a text which says "Time" "Weight" "Age" or something similar and they are naturally ordered. In these cases it will also have the units (seconds, pounds, years). In other cases the order is arbitrary (cities, politicians, products).

2. Think about the graph as a sentence. The axis on the bottom is the independent variable which causes something to change in the dependent variable represented by the other axis. The purpose of the graph can be described by filling these variables into a sentence:

The (independent variable) affects (dependent variable) by ....

For example if the bottom axis is age and the other axis is weight, the sentence might be The age of a person affect his or her weight by...

3. The third part is the legend. It will tell you the differences between the several lines, colors or symbols. Each one might be a different gender, product or characteristic of the relationship between the variables. This could mean that the graph really represents several sentences. In the example above it might be best to separate men and women into two different lines. So now there are two sentences "The age of a woman affects her weight by...." and "The age of a man affects his weight by....".

From there on you are on your own. Look at the line and fill in the rest of the sentence. If the two lines in this example jumped up from the ages 0 to 18, stayed level through the twenties and gradually went up and then down peaking at 45, the whole sentence might read "The age of a man affects his weight by rising quickly in the pre-adult years, leveling during the twenties, increasing into middle age and dropping off in the later years of life." Thinking of the lines/symbols as representing a sentence may help you to understand the purpose and interpretation of the graph.

There is also the title part of the graph which tells you what the data is about.
