# Histograms

A Histogram is a type of diagram, which graphically represents the distribution of data. Histograms are constructed in bar format and illustrate an evaluation of probability distribution of quantitative continuous data. Data is broken into intervals (bins) and is drawn with rectangles, 3D blocks, or cylinders side-by-side; with the area of each rectangle is proportional to the frequency of the observations that fall into the corresponding interval. Usually the width of rectangles on a Histogram Chart are equal in area (but it isn't a strict requirement) and the height determines the proportions of the displayed parameter.

Histograms are useful to compare data for several individual items. You can also make a Histogram to plot data that spans several periods (days, weeks, months, years) and visually depict how the values change over a time.

How to make a Histogram? Making a Histogram is an incredibly easy process when it is done with ConceptDraw PRO. The Histograms Solution enhances ConceptDraw PRO functionality with extensive drawing tools, numerous samples, and examples; also a quick-start template and library of ready vector stencils for visualization the data and professional drawing Histograms.

There is 1 library containing 8 vector objects in the Histograms solution.

## Examples

There are a few samples that you see on this page which were created in the ConceptDraw PRO application by using the Histograms 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 Histograms solution is available to all ConceptDraw PRO users to get installed and used while working in the ConceptDraw PRO diagramming and drawing software.

## Template: Histogram

This template is a ready Histogram, which requires only entering the actual and correct data at the table to refresh the information. Callouts extensively explain the principles of construction the Histograms.

## Example 1: Histogram — Mass Distribution of Food Rations

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

This Histogram illustrates the mass distribution of food rations. ConceptDraw PRO software enhanced with powerful Histograms Solution offers equal possibilities for design 2D or 3D histograms; all depends on your preferences.

## Example 2: Histogram — Age of Presidential Ascension

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

This Histogram depicts statistical data for the age of US presidents on the date of their being elected. The mean age is brightly highlighted with red, if required you can also change the color of any column according to your preference and needs.

## Example 3: Histogram — Black Cherry Tree Height

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

This example underlines the prevalence of Histograms and their applicability to huge variety of fields. It demonstrates the frequency distribution of heights of black cherry tree. Use as the base ready histograms objects offered by Histograms solution and don't afraid to experiment with look of your chart.

## Example 4: Histogram — Normal Distribution

This example was created in ConceptDraw PRO using the Histograms Library from the Histograms Solution. An experienced user spent 20 minutes creating this sample.

This Histogram is a sample of normal distribution, which is widely used in probability theory and statistics. You can see the random selection of 100 observations and their normal distribution N (0,1).

## Example 5: Histogram — Repartition of Height

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

The Histogram lets visually represent the density of data distribution. Use of color gradation on this Histogram depicting the repartition of heights for a group of population, adds the special visibility and gives the full clarity from one quick look.

## What I Need to Get Started

After ConceptDraw PRO is installed, the Histograms 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 Histograms 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 Histograms solution from the ConceptDraw STORE to use it in the ConceptDraw PRO application.

#### Start Using

Start using the Histograms 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.
