This solution extends the capabilities of ConceptDraw PRO 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).
The samples you see on this page were created in ConceptDraw PRO using the Basic Histograms solution; they demonstrate a portion of the solution's capabilities and the professional results you can achieve.
All source documents are vector graphic documents. They are available for reviewing, modifying, or converting to a variety of formats (PDF file, MS PowerPoint, MS Visio, and many other graphic formats) from the ConceptDraw Solution Park. The Basic Histograms solution is available for all ConceptDraw PRO users.
Example 1: Beetles in the River Thames
This example was created in ConceptDraw PRO 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 PRO 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 PRO 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.
