Free graph editor software for windows

The user-friendly application "Graph vX" makes it possible to display the overlaying oscillation of two sine waves easily.
Each of the two waves can be edited in amplitude, frequency, horizontal and vertical shifting.
The whole graph can be animated for a better comprehension and later be exported as .pict- or .bmp-file.
The well-structured interface and many preferences make it really easy to work with "Graph vX".
This application is a need not only for physicists, teachers or students, but for every engeneer who has to deal with linear and overlaying oscillations.

Medusa is a front end (interface) to the STRING protein interaction database. Medusa is also a general graph visualization tool.
The STRING web interface, while extensive, is static. It does not allow users to create their own networks, enhanced with STRING interactions. Medusa will allow you to experience a greater freedom in manipulating all your STRING data.
As a general tool, Medusa is very easy to use and flexible. Users can load their own data or interactively add or delete nodes and edges. It is also free for academic use and easy to install.
Medusa was originally a house tool at EMBL and has been used in a number of successful scientific projects.

Create graphs of many types of equations in minutes. It can graph multiple equations at one time. It also has the ability to save graphs.

Bar Graph MDI browses the web using GRML. GRML splits file and web page content into a form AND a view. The form is used for input controls, to handle user input for web requests.
The view is used for display controls to show web page results. The results are dsplayed using 6 different graphs. Reading either the GRML, CSV or character-delimited formats, content is displayed using a bar, pie, stacked bar, 3D bar, 3D pie, or 3D stacked bar graph.
HTML defines HOW web page content appears. There is one way HTML is displayed. This is called a display definition markup language. GRML defines WHAT web page content is. It is called a data definition markup language.
In HTML, regardless of how many web browsers there are, they all try to display a web page the same way. In GRML, the web browser decides the way to display a web page.
Why? GRML does not define a specific view of a web page. That means different GRML web browsers display the same web page differently.
GRML content consists of input controls, columns, and results. The columns and results create the view. By removing the input controls from the view, the columns and results are able to be arranged in multiple ways. This approach allows different graphs to be used on the same columns and results, each providing different information.
Unlike HTML, GRML supports "named" content. This means support for multidimensional views of a web page. To view 2 pages of message board results, or 4 pages of auction listings, or 6 pages of headlines, a HTML web browser loads each page.
Viewing each web page requires navigating between them. Using GRML, load the content in one web page, each with its own "name". Then, use a drop-down list to display the content based on its "name".
Separating the form from other web page content, support for multiple AND multidimensional views, and compatibility with other data definition formats means GRML web browsers offer another way to browse the web.

Graph CoOrdinates was written in order to allow Excel to easily find the co-ordinates of any point on an XY (Scatter) graph Graph CoOrdinates was developed for allowing MS Excel to simply search and find the co-ordinates of any point on an XY (Scatter) graph.
Currently Excel will show the co-ordinates of a data point on a series, but if there is no data point at the location you want to find, it is not so easy.
