Process Control Example

This example is written in Delphi.

The program gives a demonstration of how HG can be used in a process control environment. The display was designed in Schematic (see Schematic web site for details) and was pasted into the form file. At run time the graphical objects are loaded with real-time data.

VBDemo Example

This example is written in Visual Basic .NET.

The program gives a demonstration of a very simple X-Y plot using the .NET interface. Any plotting application in .NET can use this example as the starting point.

The graph data is loaded from a text file, so despite its simplicity the program is already a useful plotting tool.

Bar Graph Example

This example is written in Delphi.

The program draws a bar graph. The user can change the orientation (horizontal or vertical), change the width of the "bars" and animate the display.

The example shows how to draw a bar graph, change its orientation, and also shows the drawing speed of HyperGraphics.

Create Database Example

This example is written in Delphi.

The program allows the user to add and position database tables in the client area. The tables can fields added to them. The user can then add constraints and link them between the fields. The completed diagram shows the structure of the database, and this can be output to a text file or saved as a HyperGraphics format file.

This example is also the subject of an article, which can be downloaded here.

Mass Spring Example

This example is written in Delphi.

The program shows a diagram of a "mass" and "spring", and a graph. If the mass is clicked, moved up or down and then released it is animated to show the real-time motion. At the same time the graph will show a moving trace of the motion. The properties for mass, friction and spring modulus can be changed and the motion of the new system can be seen by moving the mass again.

Plot It Example

This example is written in Delphi.

The program is a general purpose graphing tool allowing ASCII files (csv, txt and prn e.g. from Excel) to be plotted and annotated. The files need to be formatted as a set of columns, the first being X, the second Y1 and so on (some example files are included). The resulting graph can be annotated by using the toolbar to add arrows, pictures and text boxes. The graph can then be printed and/or exported to an enhanced metafile. There is also a print preview window allowing the graph to be positioned and sized on the paper.

Second Order System Example

This example is written in Delphi.

The program shows the response of a second order system. The three graphs show the step response, the frequency response and the position of the poles of the characteristic equation. The poles can be dragged with the mouse, and the two other graphs show the response in real-time.

WAV Viewer Example

This example is written in Delphi.

The program displays and plays WAV files. When a file is opened the left and right channels are displayed. Selecting play from the menu will play the file while showing the progress through the file. The X-axis can be zoomed using the mouse (and auto scaled using the View->Zoom out menu item). When using large WAV files the program demonstrates the graphics drawing speed of HyperGraphics (using optimised drawing when there are more data points than pixels).

The example shows how to use the Delphi component, how to draw graphs, and how to use mouse events. It also shows how to use the print preview window, printing, and copying to enhanced metafiles.

This example is also the subject of an article, which can be downloaded here.

Bitmap Zoom Example

This example is written in Visual Basic.

The program displays a bitmap on the left and a zoom box on the right. The bitmap can be zoomed and panned by resizing and dragging the square in the zoom box. The example demonstrates flicker-free drawing, and that HyperGraphics is capable of zooming a bitmap until one pixel is occupying the whole display.

The example shows how to load and zoom bitmaps.

Contour Example

Two version of this example are available, written in Visual Basic and Visual Basic .NET.

The program displays a contour graph with some "wind turbines" and a zoom box. The normal axes have been overridden to display a grid with cross hairs. The wind turbines can be selected, moved, rotated and resized. The contour lines can display height labels or a colour map.

The example shows how to override component behaviour (for the wind turbine, axes and contour lines) and how to copy a window to the clipboard.

Waterfall Example

This example is written in Visual Basic.

The program displays a waterfall plot. Pressing the Animate button displays a changing set of data. The Select button selects the graph and allows it to be moved, resized and the projection angle changed.

The example shows how to create a waterfall plot and demonstrates the drawing speed of HyperGraphics. It also shows how to copy a window to the clipboard or printer.

Visual C++ Figure Example

This example is written in Visual C++.

The program allows a figure to be drawn by adding HyperGraphics objects to a window. The program can save, load and print figures, and also has a print preview window.

The example shows how to use HyperGraphics with Visual C++.

Borland C++ Builder Figure Example

This example is written in Borland C++ Builder.

The program allows a figure to be drawn by adding HyperGraphics objects to a window. Use the File->Add menu item to add objects.

The example shows how to use HyperGraphics with Borland C++ Builder.
