Visual Graph is a standard ActiveX component for developing graphics-related applications of various industries such as power coal chemical automation monitor simulation graphical modeling graphical topology analysis vector drawing tables geographic information system (GIS) workflow etc. very wide range of applications particularly suitable for developing the WEB-based B/S network applications. Visual Graph is so powerful but has the small size it can implement almost any operation industrial instrument without any third-party technology such as knife switch instrument panel temperature meter cylinder liquid tank conveyor belt for coal mine fan LED display slider signal light special-shaped button histogram pie chart curve and so on. So it is very suitable for industrial automation monitor simulation power coal chemical trades. Visual Graph has the similar designer as Visio it can convert the vector graphics from AutoCAD MapInfo Visio CorelDraw and other popular graphics software allows users to easily create their own vector graphic symbols. Besides supports drawing tables and you can create the topological connection between graphs. Visual Graph has an easy to learn script language and can compose its basic graphs to a new graphic element you do not need to know the implementing detail of the new element just use it like basic graph. Visual Graph has many basic properties for graphic element so as to meet various application requirements. Besides you can add two types of custom properties one is saved as data another can change the internal structure of an element for instance: change Value property of a dashboard will let the pointer deflects. Visual Graph has complete interactivity the running graph can respond many mouse and keyboard events even each graphic element can respond their own events. In addition you can create many common Windows interface elements such as dialog boxes menus popup windows.
