A Histogram is a type of diagram, which graphically illustrates an evaluation of the probability distribution of quantitative continuous data and is constructed in a bar format. This is one of main Seven tools of quality control. The data is broken into intervals, named bins, which are sequentially marked on the horizontal axis and above them there are drawn rectangles, 3D blocks, or cylinders side-by-side; at this, the area of each rectangle is proportional to the frequency of the observations that fall into the corresponding interval. Usually, the widths of rectangles on a Histogram Chart are equal, but it isn't a strict requirement, and their heights determine the proportions of the displayed parameter.
Actually, a Histogram is a series of bars of the same width, but with different heights, which show the distribution of data, at this, the column’s width is an interval in the range of observations and its height is an amount of data that falls on one or another part of the interval. The Histograms are useful to compare the 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.
The Histograms are a graphical way of presenting the tabular data, they are highly widespread in statistics allowing one to display graphically the statistical indicators. The diagrams of this type give an approximate idea about the density of the basic distribution of data and allow visualizing the functions of density of the probability of some random variable, built based on the selection, the distribution of individual measurements of the parameters of a product or process, as well as to identify the trends in changes of measured parameters of an object’s quality and to visually assess the law of their distribution.
How to make a Histogram? Making a Histogram is an incredibly easy process when it is done with ConceptDraw DIAGRAM. The Histograms Solution enhances the ConceptDraw DIAGRAM functionality with extensive drawing tools, numerous samples and examples; also a quick-start template and library of ready-to-use vector stencils for visualization data and professional drawing Histograms.
There is 1 library containing 8 vector objects in the Histograms solution.
There are a few samples that you see on this page which were created in the ConceptDraw DIAGRAM 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 DIAGRAM users to get installed and used while working in the ConceptDraw DIAGRAM diagramming and drawing software.
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.
This example was created in ConceptDraw DIAGRAM 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 DIAGRAM software enhanced with powerful Histograms Solution offers equal possibilities for design 2D or 3D histograms; all depends on your preferences.

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.
This example was created in ConceptDraw DIAGRAM 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.

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).
This example was created in ConceptDraw DIAGRAM 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.
After ConceptDraw DIAGRAM 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.
First of all, make sure that both ConceptDraw STORE and ConceptDraw DIAGRAM applications are downloaded and installed on your computer. Next, install the Histograms solution from the ConceptDraw STORE to use it in the ConceptDraw DIAGRAM application.
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.
