TeeChart Pro charting component library offers hundreds of Graph styles in 2D and 3D for data visualization, 54 mathematical, statistical and financial Functions for you to choose from together with an unlimited number of axes and 30 Palette components.

Fast speed and small memory size consumption.
The Chart graphical code speaks directly to Windows GDI API. Data is stored in dynamic arrays that are very closely mapped to memory which makes access and modifying the arrays almost as fast as the computer processor. The code is streamlined as much as possible to increase internal speed, especially when re-drawing. Other rendering outputs are OpenGL (3D), SVG, DirectX, etc but they aren't as fast as plain old GDI for realtime charting.
Divided into several modules (units) to reduce executable size.

A chart using the basic styles ( line, bar, area, pie, point ), has an executable size of only 190Kb. Packages (groups of units), are logically grouped depending on the category of each feature. Developers can create custom packages or .Net assemblies to group modules as per their own needs.

Easy to use at design and run-time.
TeeChart includes powerful and complete editor dialogs, for almost every component and sub-component. These editors are available at design-time and also at run-time. The TeeCommander component (a toolbar with charting specific buttons) provides one-click access to TeeChart editors, print preview dialogs and common features.

Complete Object Oriented API.
The architecture of TeeChart is fully Object Oriented. Almost everything is an object or belongs to an object class. Properties, methods and events follow a general, consistent style. Technically speaking, TeeChart Pro consists of 161 modules (units) and 90 form screens, totalling 798 object classes. Each class has properties that in many cases are other sub-classes, either from TeeChart API or from Embarcadero's VCL set of classes.
