New Features added to Revision 2.3
QCChart2D now supports event-based plotting. In event-based plotting, the coordinate system is scaled to the number of event objects. Each event object represents an x-value, and one or more y-values. Since an event object can represent one or more y-values for a single x-value, it can be used as the source for simple plot types (simple line plot, simple bar plot, simple scatter plot, simple line marker plot) and group plot types (open-high-low-close plots, candlestick plots, group bars, stacked bars, etc.). Event objects can also store custom data tooltips, and x-axis strings. The most common use for event-based plotting will be for displaying time-based data which is discontinuous: financial markets data for example. A more detailed description of Event-based charting is found in this white paper on the subject: An Event-based Coordinate System for Use in the Plotting of Discontinuous Time Data.
- Remove arbitrary (non-periodic) days, holidays for example, from the time/date scale.
- Allow for a sub range of a day which crosses 24:00, i.e. 18:00 to 3:00.
- Allow for multiple, active time ranges within the same 24-hour period, i.e. 9:00 to 12:00 and 14:00 to 18:00.
- Smooth panning and zooming of data across discontinuous time boundaries.
- Allow for exceptions to the predefined set of rules. For example, be able to include a weekend day, or a specific set of hours normally excluded from the scale.
- Java IDE Independent – Tested and compatible with Eclipse, JBuilder and NetBeans.
- Windows 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 to Windows 10). This is a feature of Java programs in general.
- Plot Types – Line plots, area plots, bar plots, line marker plots, floating bars, scatter plots, group plots, open-high-low-close plots, error bar plots, pie charts, contour plots, candlestick plots, line gap plots, cell plots, histogram plots, arrow plots, bubble plots, polar plots, multi-line plots, stacked line plots, box and whisker plots, floating stacked bar plots, ring plots, antenna plots, versa plots.. An unlimited number of plot types can be combined in the same chart.
- Datasets – Datasets hold the data plotted in the chart. Charts can plot an unlimited number of datasets, each dataset can contain an unlimited number of data points. Datasets can hold numeric and Java GregorianCalendar date/time based data with millisecond resolution. Mark data points invalid, forcing a break in plotted lines.
- Dataset Viewer – A new dataset viewer class will display simple and group datasets in a grid-like table. The grid can be positioned anywhere on the chart. Individual grid cells can be edited and the associated chart immediately updated using the synchronize feature.
- Coordinate Systems – Linear, logarithmic, time/date and polar coordinate systems. An unlimited number of coordinate system, and axes, can be overlaid in the same plotting area of a graph.
- Time/Date Coordinate Systems – The time/date scale is specified using Java GregorianCalendar objects. The time/date scales take into account the varying number of days in months and years. The scales can also take into account non-continuous time/date scales where a 5-day week is used, or where a full day consists of a specific time interval that can be something less than a 24-hour day. For example, it is possible to define a time/date scale where weekends are excluded and the day consists of the hours between 9:30 AM and 4:00 PM.
- Elapsed Time Coordinate System – The original Time/Date scale proved less than optimal for the display of time span data, i.e., time values not associated with a specific calendar date. Starting with Rev. 2.0, the software supports elapsed time plotting, based on a simple TimeSpan class. The elapsed time scale can be either horizontal or vertical. This includes new dataset types (ElapsedTimeSimpleDataset, ElapsedTimeGroupDataset), a new coordinate system class (ElapsedTimeCoordinates), a new axis class (ElapsedTimeAxis) and a new axis labels class (ElapsedTimeAxisLabels).
- Event-Based Coordinate System – Event-based charting further expands the plotting capability of QCChart2D – adding features important to the financial services industries. The includes new dataset types EventSimpleDataset, EventGroupDataset), a new coordinate system class (EventCoordinates), a new axis class (EventAxis) and a new axis labels class (EventAxisLabels). For more information see: An Event-based Coordinate System for Use in the Plotting of Discontinuous Time Data.

|More date axes||Standard time axes||Time axes with custom range||Elapsed time axis||Axis labels|
- Axis Types – Linear, logarithmic, time/date, event, elapsed time and polar axis types. All axis types have manual and auto-scaling modes for setting axis ranges. Axis auto-scaling modes handle multiple datasets, group data and contour data. A chart can have an unlimited number of axes.
- Axis Labels – Axes can have decimal, exponential, time, date, string and multi-line labels. Programmers can define custom numeric and time/date axis labels.
- Chart Titles – Charts can have a main title, a subhead and a footer. Axes can have horizontal and vertical titles.
- Grid Options – Grid lines of any line style and color can highlight major and minor axis tick marks.
- Export Chart Images – using the JPEG format.
- Import jpeg Image objects – Use jpeg image objects as plot elements in a chart, or as a background object.
- Legends for All Plot Types – Position horizontal and vertical legends anywhere in a chart. A chart can have an unlimited number of legends.
- Mouse Support – A group of classes implementing mouse event delegates can locate, select and move chart objects like data plots, axes, titles, and legends.
|Simple zooming – before picture||Simple zooming – after picture|
|Super zooming – before picture||Super zooming – after picture|
- Simple and Super Zooming – Zoom a simple xy axis pair, or simultaneous zoom an unlimited number of x- and y-axes.
|The MagniView cursor magnifies what is under it||The MagniView class works with charts that overlay multiple coordinate systems|
- MagniView – Similar to zooming, the mouse controls a “magnifying” rectangle as it passes over an existing chart. The area of the chart within the bounds of the magnifying rectangle is “magnified” and continuously redrawn in a separate window. The MagniView class works with charts that use a simple xy axis pair, and charts that combine one or more coordinate systems.
- Panning – Use the new MoveCoordinates class to pan data in the x- and y-dimension. Click and drag in the plot area and rescale the graph proportionally.
|Example of a data cursor and markers – click to enlarge|
- Data Cursors – XOR data cursors are used to position the mouse cursor over data points in a plot.
- Data Markers – Drop special marker symbols on to the data presented in a graph, much like a bookmark in a word processing document.
|Examples of a annotations – click to enlarge|
- Graph Annotations – Add an unlimited number single and multi-line text objects, arrows and geometric objects to a chart.
- Data ToolTips – Select a data point with the mouse and popup a tooltip window that displays the data x- and/or y-values for the data points. Programmers can create custom information displays for tooltip windows.
- Data Compression – Large datasets can be compressed, increasing display speed without loss of detail.
- Based on the Java Graphics2D API – Compatible with Java components and applications.
- High Resolution Printing – Since the underlying 3D graphics kernel uses Java Graphics2D primitives (lines, polygons and text), printer output is recreated on the printer, through Java and the operating systems printing engine, at the printer resolution and does not pass through an intermediate bitmap that can drastically lower printer output resolution.
- 100% Java Code – The software is entirely written in Java, resulting in better performance and scalability. Managed Java code makes applications easier to deploy and maintain.
- Documentation and Demo/Example Programs – The software includes a comprehensive 400 page user manual with many programming examples, Javadoc help for every class and 75 complete demo programs.

Custom Programming Services
- QCChart2D for Java is an extremely powerful and flexible software package. It contains over 1000 methods and properties in more than 100 classes. The user manual and help file documentation are more than 1000 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.
- The variety of user interfaces for charting applications is as diverse as the industries using the software. The end-user of an application at a mutual fund expects to interact with the chart in a manner different than that of an end-user in health care. The same can be said for other industries: semiconductors, quality control, teaching, biotechnology, etc.
- That is why we have written so many outstanding example programs, pulled from a wide variety of industries using many different styles of user interface.
- We 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 chart 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 chart programming genius. All you have to be able to do is describe in detail what you want the example to do.
- Using QCChart2D for Java, 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 firstname.lastname@example.org.
