# Basic Histograms

This solution extends the capabilities of ConceptDraw DIAGRAM with templates, samples and a library of vector stencils for drawing Histograms.

Histograms can represent data broken into intervals. A histogram is drawn with rectangles (3-d blocks, cylinders etc) side-by-side with the area of each rectangle being proportional to the frequency of the observations that fall into that corresponding interval. Histograms are useful to compare data for several individual items. They are often used to plot data that spans several periods (days, weeks, months, years).

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

## Examples

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

## Example 1: Beetles in the River Thames

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

A histogram is a graphical representation of a distribution of data. Visual design of a histogram may vary depending on the data and purpose of the diagram. This is an example of a small histogram that needs no vertical axis. All labels are placed near the columns, keeping the histogram clear and easy to read.

## Example 2: Basic Histogram — Amino Acid Length Distribution 2010

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

This histogram contains many columns. Each column has a long text label which makes the horizontal axis difficult to scale for proper visibility. Looking at the histogram, we can see how data is distributed in general, so this is a kind of compromise between visual clarity and accuracy of information.

## Example 3: Basic Histogram — FICO® Scores

This example was created in ConceptDraw DIAGRAM using the Basic Histograms Library from the Basic Histograms Solution. An experienced user spent 15 minutes creating this sample.

Using additional horizontal axes helps to collate bar heights with grades on a vertical axis. Use this trick in case you want to emphasize numbers that match each column’s height.

## What I Need to Get Started

Both ConceptDraw DIAGRAM diagramming and drawing software and the Basic Histograms solution can help creating the numerical data you need. The Basic Histograms solution can be found in the Graphs and Charts area of ConceptDraw STORE application that can be downloaded from this site. Make sure that both ConceptDraw DIAGRAM and ConceptDraw STORE applications are installed on your computer before you get started.

#### How to install

After ConceptDraw STORE and ConceptDraw DIAGRAM are downloaded and installed, you can install the Basic Histograms solution from the ConceptDraw STORE.

#### Start Using

To make sure that you are doing it all right, use the pre-designed symbols from the stencil libraries from the solution to make your drawings look smart and professional. Also, the pre-made examples from this solution can be used as drafts so your own drawings can be based on them. Using the samples, you can always change their structures, colors and data.
