Real-Time Graphics ActiveX is the most flexible set of real-time display controls available. Each has a unique data display and property page interface and the properties can also be set via methods. These include axes scaling, precision & labeling, graph position & size, colours, line styles and font attributes. It includes these controls:
Scrolling Graph displays analogue data like an oscilloscope or strip chart recorder. Includes line, bar, sweep, XY & stacked line graphs. Can be horizontal or vertical. Displays up to 32 channels of data
Dynamic Bar Graph is modeled on process control style face plates. Displays dynamic bars, alarm limits, plus current values & alarm status. Up to 8 channels of data. Can be horizontal or vertical
Meter displays analogue data in an arc, pie or needle meter. The meter arc starting and ending locations, radius, range, colours & alarm limits are all programmable, letting you simulate a wide variety of meter & gauge types
PID includes the Quinn-Curtis PID algorithm with anti-reset windup, output limit and rate clamping features, with an optional PID bar graph
Annunciator displays the current values & alarm states of real-time data in text form. Up to 32 channels of data
Buttons - single (on/off, momentary) and group buttons (radio button logic)
Integrated Printer Support outputs to any Windows supported printer at the device resolution
Serialisation is designed into every object in the control. Any chart can be serialised regardless of its complexity. A single call will save or restore all of the defining attributes for all of the charts and legends
Other Features include on-line help, save graph image as a DIB or copy to clipboard, refresh data without redrawing entire graph, legends
Real-Time Graphics ActiveX is also available in source code form (Visual C++) as the Real-Time Graphics ActiveX Developers Kit. |
