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 v10 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

The samples you see on this page were created in ConceptDraw PRO using templates provided with the “Histograms” solution. These documents demonstrate some of the solution's capabilities, and the results you can achieve.

All source documents are vector graphic documents. They are available for reviewing, modifying or converting to a variety of formats (Bitmap Image, PDF, PowerPoint Presentation or MS Visio) from the ConceptDraw Solution Park. The “Histograms” solution is available for all ConceptDraw PRO v10 users.

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.

Histogram Template

Example 1: Beetles in the River Thames

This example was created in ConceptDraw PRO using the Histograms Library from the 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.

Frequency Histogram

Example 2: Amino Acid Length Distribution 2010

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 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.

Histogram of Distribution

Example 3: National Distribution of FICO® Scores

This example was created in ConceptDraw PRO using the Histograms Library from the 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.

Historgram Example

Example 4: 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.

Historgram Example

Example 5: 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.
