Open source graphical software

On top of that, you can easily adapt the interface to your current task in order to cope with it in a stress-free way, though the original layout is clear enough, so you may instantly get down to work. It is optimized for Linux, Windows and Mac platforms and is translated into 12 languages. This open source design software was developed by George Williams with the help of the C-programming code and uses free-type rendering for creating various fonts. The most remarkable feature of this program is the variety of readable fonts, including such popular options as TrueType, CID-keyed and many more.

So, if you are interested in creating original fonts, here is a great tool to use for this task. In addition to the main toolset, there are many instruments for drawing, transformation, rounding, adding serifs, as well as copying individual elements or letter options.

This open source designing software attracts attention with its numerous handy tools that allow drawing entity relationship diagrams, flowcharts, network schemes, etc.

You can also try your hand at programming and add support for new shapes, thus advancing the capabilities of this program. If needed, you can print the result of your work. Verdict: SVG-Edit is first-rate graphic design software online, which is supported by most modern browsers.

It is aimed at an average user, containing only basic instruments in the toolset, namely, shape tools, hand-drawing tools, text and path editing means.

The program is divided into 2 interfaces, which work in conjunction for a smoother and more productive workflow. SVG-Edit may fully satisfy those graphic designers, who are looking for intuitive, simple-to-use software without bells and whistles. You can use the program to create detailed diagrams, elaborate illustrations and drawings.

It operates on interpreted languages, for instance, Python, and can ideally suit professional designers. Looking through its wide-ranging features, you will find clipmasks, gradient fills, Bezier curves and many other handy options. Each element is introduced as a mathematic description of its shape, e. This is rather an interesting approach, which sets this open source design software apart from the analog programs.

Verdict: Pencil2D is an efficient animation software with a strong emphasis on drawing. It allows using bit-map and vector graphics as a basis for hand-drawn animations.

Being very intuitive to use, this software impresses with a rich collection of high-end animation tools. What is more, Pencil2D supports layers, features a timeline, so you can tackle the pace of your animation. Considering all the benefits of Pencil2D, no wonder, I added it onto this graphic design software list.

In addition to the design tools, there are some meant for photo editing and drawing. The initial idea behind Pinta is to supply artists with a simple yet efficient program for creative work.

The available tools are robust enough for drawing any imaginable shape. Besides, there are 35 adjustments and effects that can give your images a professional look. Thanks to the multilingual support, designers from different countries can use this software.

Pinta is ideal for creative experiments, since it offers a complete editing history, enabling you to return to any necessary step. Verdict: Blender has outperformed lots of similar programs for 3D drawing and software design and occupies high positions in many ratings.

The main advantage is that Blender is compatible with all OS and does a great job at creating seamless animated films, 3D apps, and visual effects. Besides, this open source design software is very lightweight, so you may not worry about cluttering your disk space. Some other settings like the selection of colors , range , and axis can also be changed. After the setup, press OK button to view the 3D graphs. You can easily rotate and pan the graph through mouse to view it from all angles.

After obtaining the final graph, you can save it in a PDF document. SciDAVis is a free open source graphing software for Windows. Along with standard 2D graphs, it can also plot 3D graphs of four types namely Trajectory , Bars , Scatter , and Ribbons.

In order to plot graphs, first, you need to enter the coordinates in the X and Y fields of the table. In the table, you also get a Type menu from where you can change the coordinate format to Automatic E or Scientific e values. A Formula Menu is also present in the Table to enter formulas. Now, to get the graph, just go to the Plot menu and select a graph type from various available ones to get the desired graph.

Plus, for 3D graphs, it provides various additional tools to change the orientation of the 3D graph such as front grid , back grid , floor grid , reset rotation , etc. Veusz is a free open source graphing software for Windows. In it, you can plot graphs of both 2D and 3D types. 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. As soon as values of coordinate column get attached with the coordinates, you can immediately view the resultant graph.

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. 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. Xcas is a free and open source computer algebra system for Windows that can also be used as a graphing software.

Using it, you can plot graphs of various mathematical expressions related to Trigonometry , Exponential , Rational Expression , Real Expression , etc. Plus, it also provides an additional Cmds menu to add logical commands to the equation. In the Cmds menu, you get multiple commands like hbitand , bitor , re , im , abs , cross , and more representing Constants , Integers , Intervales , etc. After creating an equation using the expressions and commands, go to its graph menu to plot various different types of graphs such as 3D , Curved , Surface , Sequence , etc.

After plotting the graph, you can either save all the parameters along with the graph as SWF file or you can only export graph parameters as xcas text , maple , text , mupad text , etc. Apart from graphs, you can also use it to create advanced interactive geometry spreadsheet and as a high-end graphics calculator. Overall, it is a complex open source graphing software for advanced users.

It is DOS based graphing software through which you can plot both 2D and 3D graphs using expressions , functions , and equations. In terms of expressions, you can use complex number, unary, binary, logical operator , etc. If you want to draw graphs using functions, then you need to use either Elementary absolute, integer, floor, ceiling, sqrt, etc.
