The QCChart2D for .Net charting toolkit, written using C#, is for developers who want to add sophisticated interactive charting graphics to their .Net applications. The toolkit includes support for linear, logarithmic, polar and antenna coordinate systems used by engineering and scientific end users. It also includes support for advanced time/date, event, and elapsed time coordinate systems required by business end users. Advanced user interface functions allow users to interact with applications using the mouse: adding annotations, selecting, marking and moving data points, drilldown, tooltips and zooming into a particular chart region.
Anyone who purchased an earlier revision of QCChart2D for .Net  in the previous two years can upgrade for free using the the download link(s) they were sent in an e-mail at the time of the original order. Versions older than that can be upgraded.

New Features added to Revision 3.1

The current software now uses .Net Framework 6. The QCChart2D libraries, and all of the example programs have been recreated to use .Net Framework 6. All of the projects have been recreated for Visual Studio 2022.

New Features added to Revision 3

Revision 3 is mostly about the QCSPCChart products. One major change in QCChart2D is that XOR routines are now longer used, which make the software data cursor and zooming routines compatible with Windows display magnification levels other than 100%.

New Features added to Revision 2.3

Event-Based Charting

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.

Feature Summary

  • Visual Studio 2022 and higher – Starting with Revision 3.1, we have eliminated support for all versions of Visual Studio earlier than 2022. This way we no longer have to configure the libraries for the lowest common denominator of .Net, and can use new .Net features not found in original version. The software is compatible with  Visual Studio 2022,  and higher.  All example program projects are in Visual Studio 2022 format, and automatically convert to later versions of it if loaded using a later compiler. The standard DLLs are compiled for a target of .Net Framework 6. This means it should be compatible with programs written with that target or higher. There are no legacy dependencies associated with the earlier .Net runtime libraries. We have also eliminated all of the Visual Basic example projects.  And we have eliminated the Asp.Net WebForms projects, because Visual Studio 2022 and  .Net 6 no longer supports creating Asp.Net WebForms projects. See our QCChart2D for JavaScript/TypeScript if you want to add charts to any type of web page which supports Javascript.
  • Windows 32-bit/64-bit Compatible – The software will run as 32-bit on Windows 32-bit operating systems (XP and later 32-bit  versions of Windows)  and as 64-bit on Windows 64-bit operating systems. This is a feature of programs and libraries written using .Net (Version 2.0 or greater) 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-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, elapsed time, event and .Net DateTime based data. Mark data points invalid, forcing a break in plotted lines.
.Net Dataset Viewer .Net Dataset Viewer
Simple dataset viewer  Group dataset viewer
  • 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, event 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 .Net DateTime 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. Starting with Rev. 2.0, the Time/Date scale can be either horizontal or vertical.
  • Elapsed Time Coordinate System – The original Time/Date scale proved less than optimal for the display of TimeSpan 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 the .Net 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.

  • Axis Types – Linear, logarithmic, time/date, elapsed time, event, antenna, 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.
  • Axes can have decimal, exponential, time, date, elapsed time, event, string and multi-line labels. Programmers can define custom numeric and time/date axis labels.Axis Labels – Axes can have decimal, exponential, time, date, elapsed time, event, 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 – All file formats support under the .Net ImageFormat class, including JPEG, WMF, EMF, BMP, GIF, TIFF, and PNG.
  • Import .Net Image object – Use .Net 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

.Net Chart Zoom Before .Net Chart Zoom After
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.
MagniView chart MagniView chart
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.
.Net Data Cursors and Markers
   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.
.Net Chart Annotations
        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.
Bar Chart with Multi-Color Gradient

Custom Programming Services

  • QCChart2D is an extremely powerful and flexible software package. It contains over 1000 methods and properties in more than 120 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 .Net, our range of expertise includes VB, and C#  programming languages, and Xamarin cross platform development. For more information or a quote, please contact our sales department at sales@quinn-curtis.com.
