## What part of a graph tells what the bars or lines represent?

legend

The legend tells us what each bar represents. Just like on a map, the legend helps the reader understand what they are looking at.

**What type of data are pie charts and bar graphs used for?**

There are several different graphs that are used for qualitative data. These graphs include bar graphs, Pareto charts, and pie charts. Pie charts and bar graphs are the most common ways of displaying qualitative data. A spreadsheet program like Excel can make both of them.

**How do you explain a pie chart?**

A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area), is proportional to the quantity it represents.

### What is a pie chart and what type of data is it used to represent?

Pie charts are used for nominal or categorical data. When there are many levels to your variable, a bar chart or packed bar chart may provide a better visualization of your data.

**What are the five parts of a graph?**

CARMALT – Basic parts of graphs

Question | Answer |
---|---|

5 components of a good graph are: | TITLE, AXES, INCREMENTS, LABELS, SCALE |

tells what graph is about | TITLE |

changing variable is known as _____ | INDEPENDENT |

Dependent variable is on which axis that is vertical? | Y |

**How do you describe data in a bar graph?**

Bar graphs have an x- and y-axis and can be used to showcase one, two, or many categories of data. Data is presented via vertical or horizontal columns. The columns can contain multiple labeled variables (or just one), or they can be grouped together (or not) for comparative purposes.

## How do you describe a bar graph and a pie chart?

Pie charts show how much each category represents as a proportion of the whole, by using a circular format with different-sized “slices” for different percentages of the whole. Bar graphs use a series of rectangular bars to show absolute values or proportions for each of the categories.

**When should you use a pie chart or a bar graph?**

In short, a pie chart can only be used if the sum of the individual parts add up to a meaningful whole, and is built for visualizing how each part contributes to that whole. Meanwhile, a bar chart can be used for a broader range of data types, not just for breaking down a whole into components.

**What is a pie chart explain with example?**

Pie charts are used in data handling and are circular charts divided up into segments which each represent a value. Pie charts are divided into sections (or ‘slices’) to represent values of different sizes. For example, in this pie chart, the circle represents a whole class.

### What is the importance of pie chart?

The pie chart is an important type of data representation. It contains different segments and sectors in which each segment and sectors of a pie chart forms a certain portion of the total(percentage). The total of all the data is equal to 360°. The total value of the pie is always 100%.

**What are three most important parts of a graph?**

The following pages describe the different parts of a line graph.

- The Title. The title offers a short explanation of what is in your graph.
- The Legend. The legend tells what each line represents.
- The Source. The source explains where you found the information that is in your graph.
- Y-Axis.
- The Data.
- X-Axis.

**How are the bars represented in a bar graph?**

The data is represented along the y-axis of the graph, and the height of the bars shows the values. When the grouped data are represented horizontally in a chart with the help of bars, then such graphs are called horizontal bar graphs, where the bars show the measure of data.

## How are data represented in a vertical graph?

When the grouped data are represented vertically in a graph or chart with the help of bars, where the bars denote the measure of data, such graphs are called vertical bar graphs. The data is represented along the y-axis of the graph, and the height of the bars shows the values.

**Which is the best example of a graph?**

In contrast to it, charts represent datasets that aim to make the information more understood to the users. Graphs are an excellent example of the usage of charts for data visualization. What are the different types of graphs?

**What’s the difference between a bar chart and histogram?**

The major difference between them is that they plot different types of data. In the bar chart, discrete data is plotted, whereas, in the histogram, it plots the continuous data.
