## best open source drafting software for windows 7 - 6+ Best Drafting Software Free Download for Windows, Mac, Linux

Here is a list of best free open source graphing software for Windows. These software are similar to standard through which you can draw various types of 2D and 3D graphs. The main difference is that these are open source which means you can download and make modifications to their source codes. Using these graphing software, you can plot graphs of various types such as Line graph, Scatter Graph, Vertical Bar Graph, etc.

You can also use various types of equations, functions, coordinates, etc. to draw graphs. In most software, the process of creating a graph is straightforward as you just need to provide the right equation, coordinate, etc. to get the respective graph. However, some of these are quite complex as they need multiple equations and commands to draw the right graph. In these software, you also get various analyzing tools to analyze graphs and output values.

Plus, fully-fledged scientific calculators to perform complex calculations are also present in some software. Plus, various common but essential tools like Zoom in/out, Pan, Graph lines, etc. are also available. After plotting the graph, you can save it in formats like PDF, EMF, PNG, SWF, etc. My Favorite Open Source Graphing Software For Windows: GraphCalc is my favorite software because it can plot both 2D and 3D graphs using various mathematical equations.

GraphCalc is a free open source graphing software for Windows. Using it, you can draw both 2D and 3D graphs of Linear, Cubic, Trigonometric, Quadratic, etc. equations. Additionally, it also provides a scientific calculator to help you solve entered equations.

This software comes with dedicated 2D and 3D graph sections. To draw a 2D graph, go to the Graph 1 tab and enter equations on available y(t) fields to immediately get the respective graph on the XY-plane. Each y(t) function is coded with a different color, to help you quickly identify the graph of a specific equation. At any time, you can change the color of a function from the Graph options.

The output graph doesn’t have any markings, so to know coordinate of a point, you need to place the cursor at that place. Similar to the 2D graph, you can also draw 3D graphs using the 3D graph tab. In this tab, you can enter equations by accessing the 3D Graph menu > Options. At maximum, you can plot graphs of 6 different equations. Some other settings like the selection of colors, range, and axis can also be changed.

In it, you can plot graphs of both 2D and 3D types. It uses coordinate files as input of CSV, TXT, HDF5, and FITS formats to plot graphs. However, if you want to plot a graph based on equation, then you can directly specify your equation along with values of its variables to plot graphs. Now to plot graphs using the coordinate file, first, you need to combine coordinate fields (X, Y, and Z) with the coordinate values of the coordinate file using the Properties field. After that, select the type of graph that you want to plot from its toolbar such as Points, Bar Chart, Function To Data, Function, Vector Field, Box Plots, etc.

As soon as values of coordinate column get attached with the coordinates, you can immediately view the resultant graph. The resultant graph can easily be exported as SVG, PDF, EMF, PNG, JPG, BMP, etc. formats. In this software, you can also create fully colored graphs by specifying different colors to different areas of the graph using the Color menu. Besides this, it also lets you add 3D elements, grid, label, shapes, etc. to existing graphs. Graph is another free open source graphing software for Windows.

It is used to draw graphs of various mathematical functions and equations like Linear Equations, Trigonometric Functions, Cubic Equations, etc. In it, you can draw multiple graphs on the same XY-plane by entering two or more absolutely different equations. In case of multiple equations, you can assign a color scheme for each equation to quickly identify graph lines of a particular equation. Besides color coding, there are some other handy features in it like Shading (to shade different parts of the graph), Series (to add colored dot on the graph), Label (to add text), Relation (to add relations between equations), etc.

Now, to plot graphs using equations, go to Functions menu and select Insert function. In Insert Function, you get a Function equation field in which you can enter one equation at a time. Color coding option is also available in this menu, so select a color for the entered equation and click on OK button to view the graph on XY plane. Repeat the same process again to plot multiple graphs by entering more equations.

After completion, you can save the final graph in various formats like SVG, BMP, JPG, PNG, etc. Xcas Xcas is a free and open source computer algebra system for Windows that can also be used as a graphing software.

Open source describes practices in production and development that promote access to the end product’s source materials. Some consider open source a philosophy, others consider it a pragmatic methodology.

Before the term open source became widely adopted, developers and producers used a variety of phrases to describe the concept; open source gained hold with the rise of the Internet, and the attendant need for massive retooling of the computing source code. Opening the source code enabled a self-enhancing diversity of production models, communication paths, and interactive communities.

Subsequently, a new, three-word phrase “open source software” was born to describe the environment that the new copyright, licensing, domain, and consumer issues created. (Wikipedia) If you are looking at open source software to make your Windows 7 experience more better, we have compiled a list of top 10 open source software for Windows 7 OS.
