What you see below is a double bar chart. Take a close look at it and study it, so you can become familiar with its features After you have examined the double bar chart above, here are a few good observations you can make from the graph: The scale is on the left of the graph and it is 10…

Making Line Graphs

Making line graphs to show change over a period of time is a straightforward process. Instead of drawing bars, a dot is used at the correct height Take a look at the following line graph. Then, we will explain some of its features The title is ” Scores on a basic math test” The scale is at the left of the graph. The distance between each square is 10, so the scale is 10 It shows scores for a student over a period of time or after taking 10 basic…
