The Real-Time Graphics Tools for Java charting toolkit, entirely written using Java, is for developers who want to add sophisticated real-time graphics to their Java applications and applets. The software integrates the QCChart2D charting software with real-time data structures and specialized rendering routines. It is designed for on-the-fly rendering of the real-time data using new specialized classes for scrolling graphs, gauges (bar graphs), meters, annunciators and text. Plot objects created using the QCChart2D classes can be freely mixed with the new Real-Time Graphics Tools for Java classes. Advanced user interface features such as zooming and tool-tips can used with real-time scrolling charts. A process variable class manages real-time data, an unlimited number of alarms, and data archiving. A PID (Proportional, Integral and Derivative) control class implements sophisticated control algorithms applicable in a wide array of applications. Real-Time displays can be sent to supported output devices at the resolution of the device, creating presentation quality printouts, slides, or transparencies.

Revision 2.0 adds scrolling support for elapsed time coordinate systems, vertical scrolling, a grid viewer for process variables, and a collection of “Auto” classes which simplify the creation of bar indicators, meters, dials, clocks, panel meters and scrolling graphs. Since QCRTGraph is built on top of the QCChart2D software, there are many new features associated with Revision 2.0 of the QCChart2D software.

Design Considerations

bulletUpdates of data classes are asynchronous with rendering of graphics to the screen.
bulletReal-Time plot objects are derived from QCChart2D plot objects resulting in standardized methods for setting plot object properties.
bulletAny standard plot type from the QCChart2D software package, both simple and group plot types, can be implemented as scrolling graphs.
bulletThere are no limits on the number of process variable channels, no limits on the number of alarm limits associated with a process variable, no limits on the number of real-time plots in a graph.
bulletThe update of real-time objects will not interfere or overwrite other objects and will follow the z-order precedence established when the graph was created.

 

New Features added to Revision 2.0

bulletNew scrolling support - for elapsed time coordinate systems
bulletVertical scrolling - with auto-scaling for numeric, time/date and elapsed time coordinate system.
bulletA collection of ChartView/JPanel based  “Auto” classes - simplify the creation of bar indicators, meters, dials, clocks, panel meters and scrolling graphs.
bullet RTProcessVarViewer - a class for the grid-like display of process variable historical data in a table

   

Feature Summary

bullet Includes the QCChart2D Charting Tools for Java - The Real-Time Graphics Tools for Java includes the complete QCChart2D Charting Tools for Java.
bulletWindows 32-bit/64-bit Compatible - The software will run as 32-bit on Windows 32-bit operating systems (XP and 32-bit  versions of Vista and Windows 7)  and as 64-bit on Windows 64-bit operating systems (64-bit versions of Vista and Windows 7). This is a feature of Java programs in general.
bulletJava IDE Independent - Tested and compatible with Eclipse, JBuilder and NetBeans.
bullet Based on the Java Graphics2D drawing technology - Compatible with Swing components and applications.
bullet New Features in Revision 1.7 - Two-color gradients can be applied to bars and other area objects. Also,  the QCLicense license file has been eliminated, along with  the need to purchase redistributable licenses.
bullet Process Variable and Alarms - Real-time data is stored in RTProcessVar classes. The RTProcessVar class is designed to represent a single process variable, complete with limit values, an unlimited number of high and low alarms, historical data storage, and descriptive strings for use in displays.

 

                              

                              

Clockwise from top: Solid bar indicator, segmented bar indicator, custom segmented bar indicator, horizontal solid bar indicator, and pointer indicator. Only the green bars represent the bars (and pointer) represent the bar indicators. Other items also shown include axes, axis labels, panel meters, and alarm indicators.

 

 

   

         

   

There are an infinite number of meter designs possible using a variety of meter arc ranges, meter scales, meter axes and meter indicator types

bullet Single Value Indicators - A single value indicator is a real-time display object that is attached to a single RTProcessVar object. This includes single channel bar indicators (which includes solid, segmented, custom and pointer bar indicators), meter indicators (which includes meter needles, meter arcs and meter symbol indicators), single channel annunciator indicators, panel meter indicators and scrolling graph plots based on a QCChart2D SimplePlot chart object.

 

 

   

   

The only limit to the number of annunciator cells you can have in an RTMultiValueAnnunciator graph is the size of the display and the readability of the text.

 

   

Each bar in the RTMultiBarIndicator can have individual colors and alarm limits.

 

   

The RTGroupMultiValuePlot class turns QCChart2D GroupPlot objects, like the MultiLinePlot object above, into scrolling plots.

 

bullet Multiple Value Indicators - A multiple value indicator is a real-time display object that is attached to a group of RTProcessVar objects. This includes multiple channel bar indicators (which includes solid, segmented, custom and pointer bar indicators), multiple channel annunciator indicators, panel meter indicators organized in a grid, and scrolling graph plots based on a QCChart2D GroupPlot chart object.

 

 

   

   

   

The alarm indicators can have one of three forms: pointer style symbols, horizontal or vertical lines, or horizontal or vertical filled areas.

 

bullet Alarm Indicators - Alarm indicators are used to display alarm lines, symbols and fill areas for the RTProcessVar objects associated with the single value and multiple value indicator classes.

 

 

                            

Numeric panel meters can be the primary display method for real-time data, or they can be used as adjuncts to other real-time indicators such as bar indicators and meters.

 

bullet Panel Meter Indicators - The RTPanelMeter derived classes are special cases of the single value indicator classes that are used throughout the software to display real-time data in a text format. Panel meters are available for numeric values, string values, time/date values and alarm values.

 

 

   

A useful benefit of multiple meter scales is the ability to display both Fahrenheit and Centigrade scales at the same time.

 

   

          

Meter tick mark strings can be horizontal, parallel and perpendicular to the tick mark.

 

bullet Meter Axis Objects - Meter indicators needed new classes to support the drawing of meter axes, meter axis labels and meter alarm objects.

 

              

RTFormControlGrid objects are arranged in a row x column format. Additional panel meter objects (numeric and string panel meters in the track bar example above) can be attached to the primary control grid object.

 
bullet Form Control Classes - The Java JButton and JSlider objects have been subclassed and enhanced for use in instrument panels. The RTControlButton class implements on/off colors and on/off text for momentary, toggle and radio button style buttons. The RTTrackBar class adds real-world scaling based on double values to the integer based JSlider class. RTControlButton and RTTrackBar objects can be group together in a grid, organizing the control objects functionally and visually.

 

   

A display can have multiple scroll frames. The frames can be in separate plots and update in a synchronized fashion, or they can overlap the same plotting area.

 

Vertical Scrolling Chart

A vertical scroll frame can manage a time/date, an elapsed time, or a numeric, vertical scrolling coordinate system.

 

bullet Scroll Frame -  A scroll frame manages constant rescaling of coordinate systems of plot objects that are displayed in a scrolling graph. Revision 2.0 adds a vertical scroll frame to the software.

 Auto Indicator objects

The RTAuto...Indicator objects encapulate all of the objects needed to create real-time bargraphs, dials, clocks, panel meters and scrolling graphs

 
bulletRTAuto… Indicator Classes - New classes have been added to simplify the creation of bar indicators, meters, dials, clocks, panel meters and scrolling graphs. These classes encapsulate all of the elements needed to create a particular real-time indicator type: coordinate system, axes, axes labels, titles, process variable, alarms, and panel meters for numeric readouts and alarm status. The auto-indicator classes are setup as a self contained UserControl derived objects, placeable on a form, and can be modified using methods and properties.

 

RTProcessViewer grid

The RTProcessViewer grid displays the historical data for an RTProcessVar object

 
bullet Process Variable Viewer - the RTProcessVarViewer  class displays the historical data of a process variable in a grid like table.

 
bulletDocumentation and Demo/Example Programs - The software includes a comprehensive 400 page user manual with many programming examples, Javadoc help for every class. Hundreds of programming examples in Java.

Custom Programming Services

bulletQCRTGraph for Java is an extremely powerful and flexible software package. It contains over 1500 methods and properties in more than 150 classes. The user manual and  help file documentation are more than 1500 pages. This can be overwhelming to the average programmer who wants to start programming today and have the prototype of an application working in a week.
bulletThe variety of user interfaces for real-time graphics applications is as diverse as the industries using the software. The end-user of an application in the automotive industry expects to interact with the real-time display in a manner different than that of an end-user involved in real-time stock trading. The same can be said for other industries: health care, semiconductors, quality control,  biotechnology, etc.
bulletThat is why we have written so many outstanding example programs, pulled from a wide variety of industries using many different styles of user interface.
bulletWe know that your application may be similar to, but still uniquely different from any of our example programs. To that end we offer our programming services to write for you a custom example program that demonstrates how to code the real-time display format and user interface you want. That jump start to your project can save you many weeks of work and make you look like a real-time graphics programming genius. All  you have to be able to do is describe in detail what you want the example to do.
bulletUsing QCRTGraph for Java, our expertise includes writing applications that can be run on workstations, and applets that can run in web browsers.  For more information or a quote, please contact our sales department at sales@quinn-curtis.com
