# Line Graphs

What is a Line Chart? Line Chart or Line Graph is a basic type of diagram, which depicts information as series of data points connected by straight line segments. Line Charts depict quantitative metrics and assist one in visualizing changes of data over time intervals.

A Line Graph is used to compare two variables (independent or dependent) which can be plotted on a 2D graph to visually show how one variable is affected by another. The Line Chart is useful in displaying information or data that change continuously over the time. Line Charts allow one to effectively predict results of data, which are not yet recorded and also to self-regulate values of the main variable at each segment. Line Graphs are used in mathematics, statistics, business, mass media, and many other fields; they are also useful for visualization of data and results of experiments for reports and other documents.

How to draw a Line Graph with ease? The Line Graphs solution extends the capabilities of ConceptDraw PRO with professionally designed templates, samples, and a library of vector stencils for drawing perfect Line Graphs.

There is 1 library containing 5 objects in the Line Graphs solution.

## Examples

There are a few samples that you see on this page which were created in the ConceptDraw PRO application by using the Line Graphs solution. Some of the solution's capabilities as well as the professional results which you can achieve are all demonstrated here on this page.

All source documents are vector graphic documents which are always available for modifying, reviewing and/or converting to many different formats, such as MS PowerPoint, PDF file, MS Visio, and many other graphic ones from the ConceptDraw Solution Park or ConceptDraw STORE. The Line Graphs solution is available to all ConceptDraw PRO users to get installed and used while working in the ConceptDraw PRO diagramming and drawing software.

## Template: Line Graph

This Line Chart template is ideal for quick-start in drawing a Line Chart. Filling the table with new data will lead to automatically reflection the changes on chart, equally as the change of colors in the table’s head.

## Example 1: Line Graph — Relative Price Changes

This example was created in ConceptDraw PRO using the Line Graphs Library from the Line Graphs Solution. An experienced user spent 10 minutes creating this sample.

This sample represents the line graphs of changes of prices depending by year for different groups of goods. Different coloring is used for easy visual assessment and comparison of the dynamics with one look.

## Example 2: Line Graph — Number of Airlines Departures in the Given Years

This example was created in ConceptDraw PRO using the Line Graphs library from the Line Graphs solution. An experienced user spent 5 minutes creating this sample.

Line charts are incredibly helpful in various fields; they can be used to illustrate economic principles and trends. This chart depicts a period of seven years and the corresponding statistical data on the number of airline departures for each of these years.

## Example 3: Line Graph — France Export of Goods and Services

This example was created in ConceptDraw PRO using the Line Graphs Library from the Line Graphs Solution. An experienced user spent 5 minutes creating this sample.

This Line chart demonstrates the data from the European Economic Forecast for the exporting of different goods and services by France. ConceptDraw PRO lets to design similar graphs for other countries in minutes and then visually compare them.

## Example 4: Line Graph — Steps Walked in a Week

This example was created in ConceptDraw PRO using the Line Graphs Library from the Line Graphs Solution. An experienced user spent 10 minutes creating this sample.

This sample shows the steps walked in a week in form of Line Chart and is based on the statistical data from the website of the Bureau of Labor Statistics, U.S. Department of Labor. Varied colors are used for additional visuality, especially on the segments that practically match.

## Example 5: Line Graph — Percent of Students a 36 on ACT

This example was created in ConceptDraw PRO using the Line Graphs library from the Line Graphs solution. An experienced user spent 5 minutes creating this sample.

This Line graph sample represents the percent of students achieved a 36 on ACT (American College Testing) at the period from 1997 to 2011, the data are marked as points on chart and connected with line segments.

## What I Need to Get Started

After ConceptDraw PRO is installed, the Line Graphs solution can be purchased either from the Graphs and Charts area of ConceptDraw STORE itself or from our online store. Thus, you will be able to use the Line Graphs solution straight after.

#### How to install

First of all, make sure that both ConceptDraw STORE and ConceptDraw PRO applications are downloaded and installed on your computer. Next, install the Line Graphs solution from the ConceptDraw STORE to use it in the ConceptDraw PRO application.

#### Start Using

Start using the Line Graphs solution to make the professionally looking numerical data by adding the design elements taken from the stencil libraries and editing the pre-made examples that can be found there.
