Linux Data Visualization ToolThere are a number of applications for graphical visualization of data on Linux, from simple 2-d drawings to the-to-date cartography, to scientific graphics programming and graphical simulations. Fortunately, there are many open source implementations of these tools, including Gnuplot, GNU Octave, Scilab, MayaVi, and Maxima. Each tool has its own pros and cons and is designed for different applications. Exploring these ope

HTML5 is undoubtedly the most favored technology, today recommended 8 HTML5 drawing tools, the same stunning your eyeballs! Most of these drawing tools are implemented with a HTML5 canvas (Canvas), partially supplemented by JavaScript. For every web designer, drawing and sketching is one of their favorite things in their work. Sketch and cartography are an important feature in the work of design workers. HTML5 will show a limitless future in this res

Because the screen-cutting step of Windows system is troublesome, we need a software that can quickly and conveniently cut screen. And the Scarecrow Convenience tool is a lightweight screen-cutting function of the software. In the screen, the Scarecrow not only avoids the software's own interface, but also can provide real-time resolution, improve the size of the screenshot of the controllable. Let's take a look at it in detail below. Scarecrow Convenience Tools Many people are accustom

HTML5 is undoubtedly one of the most favored technologies, and each Web designer is enthusiastically discussing the rise of this magical markup language. HTML5 is an effortlessly learned markup language, but it can provide fascinating, artistic features that help web designers complete their ideation. HTML5 can be easily understood and mastered by a designer.Sketching and mapping is an important feature in the work of design workers. HTML5 will show a limitless future in this area.Today, I've co

Theory and method of data-spatial data mining technology Gejoco (Information Institute of Southwest Agricultural University 400716) This paper briefly discusses the theory and characteristics of spatial database technology and spatial data mining technology, this paper analyzes the level and method of spatial data mining technology, and emphatically introduces the methods of spatial data mining, such as classification, clustering, association rules and so on, and points out the problems, dev

And many of the vector editing software, the Fireworks in the vector graph of objects than the bitmap object Modifiability. A lot. So the non-material cartography, more time is made into a vector graphics, to facilitate the time saved, at any time to edit. And the editor includes the object of the selection, mobile, fill, rotation, and deformation, and so on. 1And change the path Simplified path: in order to make a irregular vector path becomes more

Introduction In China, Auto CAD has been widely used in all walks of life, playing a more and more important role and become one of the design tools that engineering technicians must master. In the AutoCAD platform in the process of product design, often used in some commonly used graphical symbols, for these high repetition rate, and the use of very frequent graphics, we can make it into blocks, can be inserted at any time, so as to achieve the purpose of re-use. Tile can improve the efficienc

AutoCAD or other design software to express his design concept, the first step is to put this drawing design ideas in AutoCAD, and this expression is only a beginning, he should be in accordance with the norms of cartography, the regulation of its rules for a full expression, The process of using the idea of design as a document is usually a trivial matter and takes time. Secondly, it realizes the separation of design idea and expression form in Aut

The has n points, which can only be located on or below the midpoint of a square, and all square edges look equal and do not overlap, seeking the maximum edge length. The two-part answer. It doesn't matter if the x-coordinate of a point is not less than the length of the edge. If the is less than, consider the problem below. If the y-coordinate is less than the length of the edge, then one must be put down; if equal, one in the previous, one in the lower, and if less than twice times the
