gtkscope - Project Hosting on Google Code gtkscope is a simple program to read and display analog data captured from a Comedi device. Think of this as a gtk oscilloscope Reason xoscope is just plain ugly ;) Just kidding, all aside xoscope works relatively well however there appears to be substantial lag when sampling at high frequencies (~30 kHz). I needed a program that would allow me to monitor physiological data sampled at a high frequency (~30 kHz) on several channels (>8). Relational Relational an educational tool to provide a workspace for experimenting with relational algebra, an offshoot of first-order logic. It provides GUI that can be used for executing relational queries, and also provides a command line interface. Provides a standalone Python module that can be used for executing relational queries, parsing relational expressions and optimizing them.

Numerical Algorithms Group IRIS Explorer is NAG's powerful tool for developing customized visualization applications. Its visual programming environment enables you to develop, prototype and build these applications quickly and easily. IRIS Explorer, with its broad range of visualization techniques, from simple graphs to multidimensional animation, enables you to readily discern trends and relationships in your data. IRIS Explorer is a standards-based package that utilizes the Open Inventor™, ImageVision™ and OpenGL™ libraries, together with NAG's world-class numerical libraries. It is available on a broad range of Windows PC, Unix and Linux platforms. Its easy to use point-and-click interface means that users spend less time programming and developing customized visualization applications.

plot3d (1E) In the splot , the zero-point of Z-Axis is placed above the XY plane. To move this origin onto the XY plane, use set ticslevel . When ticslevel=0, the zero of Z-Axis moves to on the XY plane. gnuplot> set ticslevel 0 gnuplot> splot (x**2)*(y**2)

Plot your graphs with command line gnuplot February 12th, 2009 mysurface Posted in Developer, gnuplot | Hits: 235527 | 14 Comments » gnuplot is a command line driven graph plotter tools for us to generate graphs. The common graphs that we are looking forward to present the resource performance per seconds, hours, days, weeks or months are usually plot graphs, which it consist of lines and dots. gnuplot allows us to read the data from text files which contains values in tabular format. For example, I have a module that extract raw values into logs based on the specified interval.

Gscope: A Software Oscilloscope Library Copyright © 2000 by Ashvin Goel Gscope is a software oscilloscope library build using the GTK and GNOME graphical toolkits. The scope displays signals in real-time and allows recording and playback of signal data. It can be used to simultaneously display multiple signals and for modifying signal parameters on the fly. In general, the scope can be used to monitor, display and debug various types of "real-time" data. In addition, the scope can be used for plotting or graphing file data that is in a tuple format.

GNU Octave GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. Protovis Protovis composes custom views of data with simple marks such as bars and dots. Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction. Protovis is free and open-source, provided under the BSD License. It uses JavaScript and SVG for web-native visualizations; no plugin required (though you will need a modern web browser)!
