How to Draw a Pie Chart Using ConceptDraw PRO

A pie chart represents data, in a clear and easy to read round (pie) form. A circular pie chart is divided into sections (slice). Each "slice" depicts the It reflects the proportion of each component in the whole "pie". This type of chart is most often used for the visualization of statistical data. That is why pie charts are widely used in marketing. As pie charts show proportional proportional parts of a whole, they are good for various visual comparisons. For example, it is difficult to imagine a more intuitive way to show segmentation and market share. ConceptDraw PRO allows you to draw a simple and clear Pie Chart using the Pie Charts solution.

Data structure diagram with ConceptDraw PRO

Data structure diagram (DSD) is intended for description of conceptual models of data (concepts and connections between them) in the graphic format for more obviousness. Data structure diagram includes entities description, connections between them and obligatory conditions and requirements which connect them. Create Data structure diagram with ConceptDraw PRO.

IDEF4 Standard

Use Case Diagrams technology. IDEF4 standard implies not only graphical presentation but the additional information about diagrams of heredity, methods systematization and types which are contained in specifications.

Directional control valve

"Directional control valves are one of the most fundamental parts in hydraulic machinery as well and pneumatic machinery. They allow fluid flow into different paths from one or more sources. They usually consist of a spool inside a cylinder which is mechanically or electrically controlled. The movement of the spool restricts or permits the flow, thus it controls the fluid flow. ...
The spool (sliding type) consists of lands and grooves.The lands block oil flow through the valve body. The grooves allow oil or gas to flow around the spool and through the valve body. There are two fundamental positions of directional control valve namely normal position where valve returns on removal of actuating force and other is working position which is position of a valve when actuating force is applied. There is another class of valves with 3 or more position that can be spring centered with 2 working position and a normal position. ...
Directional control valves can be classified according to:
(1) number of ports;
(2) number of positions;
(3) actuating methods;
(4) type of spool." [Directional control valve. Wikipedia]
