# Graphing:

A **line graph** is used to show or change over time. On the **X axis (the x axis is on the bottom of a graph)** , you put the **independent variable** and on the **Y axis (the y axis is on the left of a graph)** , you put the **dependent variable**. Usually, a line graph is not the best graph to find exact numbers, because it is harder to read opposed to a bar graph. Here are two examples:

A **bar graph** is used to compare two or more things.This graph is a good example, because it has a title, and it is labeled. To have a nice and neat bar graph you should include a title, labels, key, x-axis, and y-axis. Mostly you use a bar graph to measure animals, fruit, or any other items. Here is an example:

A **Pie graph** shows you **Percentages**. You must make sure there are **Percentages** are there so the reader will know how much of what your testing has. Here is an example of one:

## What is needed to have a successful graph

There are many things needed to have a successful graph. For example, a **title** is important to have so that the reader knows what the data is about. Another thing a graph needs is a **legend/key** so the reader can identify what has been measured. Every graph has to have a **date** so that the reader knows when this data has been recorded. If you are making a line or a bar graph, you need to label your **X** and your **Y** **axis** so the reader knows what is measured and what the measurements are. A good graph also needs an **author** so that the reader knows who made it. It would also be good if your graph is **neat** and not smudged so it's easier for the reader to read the graph. You can remember some of these things will **TALDOGS **T- **tittle**, A- **author**, L- **legend/key**, D- **date**, O- **origin**, G- **graph**, S- **scale**. Those are some things to make your graph well written.

A **point graph** is kind of like a **line graph** but dosent have a line going through the points. Instead a **point graph** has dots or points to where the measuerment of something. A **point graph** is not used as often as some other graphs but usally you use this graph in school more then other graphs.
