Charts and Graphs-Types of Graphs Free Download. The use of graphs and charts are a great way for users to comprehend information. There are numerous types of charts and graphs which organize data in different ways and are often employed for business use.

It is essential to understand the various kinds of charts and graphs so that you can select the most appropriate one to present your data particularly when you are creating professional presentations. This article we’ll look at different graphs, charts and their numerous applications.

What are graphs and charts?

Charts and graphs are visuals which show the relationships between data . They are intended to show the data in a manner that is simple to comprehend and to remember. The majority of people use graphs and charts to show patterns, trends and connections between different sets of data.

Charts can be a good choice for certain kinds of data, whereas charts are suitable for other types of data. The graph or chart you select will largely depend on the main factors you want other people to take away from the data you’ve accumulated.

## Graphs and charts How do you tell the differences?

Many people refer to “graph” and “chart” interchangeably, they are two distinct visuals. Charts are diagrams, tables or images that help organize huge quantities of data in a clear and succinctly. Charts are used to understand the current information and make predictions. The graphs, however, concentrate on raw data, and demonstrate patterns across time.

## Different kinds of graphs

You can select from a variety of kinds of graphs to show data, such as:

### 1. Line graph

Line graphs demonstrate how similar data is changed over a particular amount of time. One axis may show a number, and another axis displays the timeline. Line graphs can be useful to illustrate trends such as temperature variations on certain dates.

### 2. Bar graph

Bar graphs are a straightforward way to evaluate numbers of all kinds such as inventory levels, group sizes and financial forecasts. Bar graphs are available both vertical and horizontal. The one axis is used to represent the categories, and the other is how much each of them is worth. The length or the height of each bar corresponds directly to the value it holds. Marketing firms often employ bar graphs to show scores and responses to surveys.

### 3 . Pictograph

Pictographs use symbols or pictures to display information instead of bar. Each pictograph represents a particular quantity of things.

Pictographs are beneficial when you wish to present data in a visually appealing format like an info graphic. For instance, you can make use of a photo of a book in order to display how many books the store sold in just a few months.

### 4. Histogram

A histogram is a different kind of bar graph which illustrates the distribution of numerical data across various categories. The majority of people use histograms to show the statistical aspects of a situation.

A histogram, for instance, could display the number of people who are in a particular age group within a particular population. The length or height of each bar on the histogram indicates the number of people who belong to the respective grouping.

### 5. Area graph

Area graphs depict the change within one or more variables over a specific duration of time. They can be useful when showing patterns and trends. Like the line graph the area graph uses dots joined by a line. But an area graph is characterized by coloring the lines along with the horizontal line.

You may use several lines and the colors between them to illustrate the way that multiple numbers are a part of a larger picture. For instance, a retail store could use this technique to present the earnings of various stores within the same time frame.

### 6. Scatter plot

Scatter plots employ dots to illustrate the relation between two variables. One could use the scatter plot graph to demonstrate the relationship between weight and height, as an instance. The procedure involves plotting one variable on the horizontal axis, while the other is plotted on vertically.

The resultant scatter plot shows the extent to which one variable impacts the other. If there isn’t any correlation then the dots appear randomly within the plot. When there’s a significant correlation, the dots appear close and create a line across the graph.

## Different kinds of charts

There are seven standard charts that you can employ to present data:

### 1. Flowchart

Flowcharts can help you organize the steps, decisions , or actions of a process from beginning to conclusion. They typically have multiple starting points or endpoint, and show the various ways you can go within a procedure to get from beginning to conclusion.

Flowcharts are often used to illustrate complex situations. They make use of specific shapes to show various aspects of the process. Furthermore, they usually include a legend explaining the meaning behind each shape.

### 2. Pie chart

Pie charts show the various components of a complete. It appears to be a circular shape split into many pieces similar to the slices of a pie. The pieces have different sizes depending on the proportion of the total they make up.

Every piece typically has the label that represents its value in relation to the total. Professionals may use pie charts in presentations for business to illustrate the different segments of the population or market research responses, as well as budget allocations.

### 3. Gantt chart

Gantt charts illustrate project schedules. The horizontal axis is the timeline for the project in terms of days months, weeks, days or years. The chart shows each project task as a bar along the vertical axis.

Bar length is based on the beginning and ending date of the task however sometimes there’s an axis of vertical lines for that day’s date. Project managers utilize Gantt charts to keep track of the progress and the status of every project.

### 4. Waterfall chart

Waterfall charts display variations across time. They show both the positive and negative effects of different variables on the initial value like the balance at opening. Waterfall charts can be useful when showing financial statements, studying the performance of a business and comparing profits.

It is possible to use this chart to show the budget in relation to the amount you spend. The negative and positive values typically are represented by a color code. illustrate how the value grows or decreases as a result of various changes over time.

### 5. Gauge chart

Gauge charts display information by readings on the dial. They indicate where a particular data point falls within a certain minimum or maximum range. A needle shows the value of a scale. A lot of people utilize gauge charts to show the speed, revenue goals, and temperatures.

### 6. Funnel chart

Funnel charts show the way values change over different stages. They are the widest at the top, and the most narrow at the lowest. Funnel charts are particularly useful in tracking sales processes.

They can also be used to show the traffic on websites, such as the amount of people who visit the site as well as the pages visited and the downloads that were made. Order fulfillment is a different usage of funnel charts because they are able to easily display that “number of orders that were placed that were cancelled and then delivered.

### 7. Bullet chart

A bullet chart is a way to evaluate the effectiveness of a particular objective or goal. Certain bullet charts, for instance ones that show profits, have targets that are high. Other charts have lower goals, such as those that show expenses. Many people use bullet charts in dashboards to show the performance in the key performance indicators (KPIs). Bullet charts are similar with a bar chart. It comprises three parts:

• A line that shows the desired value
• A bar in the center that shows the real value
• Bars with colored bars that show the performance indicators
