Diagramming program. Graph for plotting mathematical functions

Graph – an application for building mathematical graphs, which are based on a function. The program is executed with open source code. Any existing functions are supported here, and for convenience, they are divided into categories. You can create any graph, be it sine, cosine, algorithm, etc. The graph itself is also customizable; you can set the thickness of its lines and their color, or specify the indentation with which the data will be displayed. Graph allows you to display function conditions, such as equality or vice versa.

You can save the schedule anywhere graphic format. Moreover, you will be able to export the coordinate system and the graph itself to a file, which other programs can then work with, for example, . The graph builder can also display their values, recalculate the data, insert comments, make custom functions, set animation and much more.

Advantages of Graph:

• simplicity - you can understand the program in a matter of minutes;
• supported simple functions, parametric and polar;
• the ability to construct any auxiliary lines;
• You can add any inscription near the graph;
• it is possible to copy the result as a picture;
• the ability to build a graph using points or tabular data;
• There is a print to file function.

Let's finish

The first impression of a charting program is deceiving, and contrary to the belief that it is difficult to understand, you will be able to figure it out quickly in the fall. After just two minutes of investigation, we managed to build a simple linear graph. Moreover, everyone is supported here possible methods data output. This is both a simple printout and transmission of the result third party programs. The coordinate system itself is also very flexible.

The application will be useful not only for students who learn all the tricks of mathematics, but also for their teachers. In addition, you do not need to register for the program. Click the button below to download for free latest version programs via direct link.

Any freelancer has encountered a situation where he needed to quickly solve a problem, but he did not have the necessary tools. Today, with access to the Internet, many of the tasks can be solved directly in the browser - there are many services on the network for adjusting images, working with audio and video files, text, tables, and so on. In addition, there is often a need to illustrate the created content with graphs and diagrams. The graphs are very informative and allow you to display the relationship between various types data, it is difficult to do without them when creating presentations or reviews and they must be used if possible. FreelanceToday presents 10 tools for creating graphs and charts.

Most of the tools presented are quite simple, so mastering them will be very easy.

Chart Maker is a simple and intuitive tool for creating charts. With Chart Maker, the user can create five types of charts: line, pie, bar, Venn and scatter charts. When finished, you can specify exact size diagrams in pixels and either save it on your computer’s hard drive or publish it on the Internet - the service generates a link to the image.

The ChartGo tool allows you to create colorful and informative charts. You can work with different types of charts, including histograms, line graphs, pie charts and area plots. Using the settings, you can adjust the color and size of the image, change the font style (italics and bold), and also mention the source of information. Using the service, you can create your own investment and stock charts, Forex charts, and also illustrate any data related to finance.

One of the features of ChartGo is the ability to edit a saved graph or chart. The image is stored on the ChartGo server and can be modified. The server generates a link to the chart, so when the original image changes, the chart published on the website or blog page also changes.

The diagram is in a great way for visual presentation of information. Using free tool Online Charts you can create the most different graphs and charts: line, pie, radar, pyramid, area charts and many others. It is possible to work with color and font type. You can also choose appearance diagrams: 2D or 3D. The finished schedule can be saved in PNG formats, JPG, PDF and CSV. A link to the chart is also provided. The diagram can be posted on a website or blog, or shared on social networks Facebook, Twitter and Google+.

A very easy to use chart generator created by John Winstanley. The mention of Google in the name of the tool is explained simply - the generator uses the Google API. Using the service, you can create accurate, vivid and informative graphs and charts. The finished result can be saved on your computer or published on the Internet. The service also generates an HTML image tag. The user has relatively few tools at his disposal, but all the necessary types of charts and graphs are available. You can create charts with multiple data sets, grouped histograms (vertical and horizontal), and choose a 2D or 3D appearance.

Line graphs are indispensable when you need to display certain types of data or demonstrate current trends. Line Graph Maker is a very easy to use tool for creating line graphs. You can also create simple pie charts and histograms using the service.

The RAW tool is a powerful platform for creating colorful graphs and charts. The tool allows you to display information 16 in various ways. The creators of the service did a good job on the functionality; the platform can be used in serious research, since Raw is an intermediate option between professional spreadsheet editors and vector graphic editors. Any person working with confidential information, will be glad to know that Raw processes data only through the browser and does not store it on its servers. The platform does not allow you to create simple line graphs and histograms; the creators of the service suggest using other tools for this. available tools. But if you need to create an alluvial diagram, a circular dendrogram, or something else complex and unusual, then you can use Raw.

amCharts is designed to create modern and stylish chart templates that can be used in presentations, conferences, and to illustrate content. There are several initial diagrams; the platform interface can be fully configured in a couple of minutes. The main advantage of the service is the ability to create interactive charts and diagrams, however this will require the user to at least basic knowledge HTML, since you will have to work with generated HTML code that interacts with JavaScript libraries.

If you need an easy-to-use tool for creating charts, then you should pay attention to the Plotvar online service. The tool is ideal for illustrating financial analysis, presentations, forum posts or social networks. You can create line graphs, histograms, and pie charts. It is also possible to create dynamic graphs. A “live” chart will allow you to present information in dynamics, which will be appreciated by those users who work with constantly changing data.

Infogram is known as one of the leading infographic creation apps. But it also has tools for creating charts and graphs, with more than 30 variations. Infogram is a premium tool, it is paid, so you should create charts in it only if absolutely necessary. As a last resort, you can sign up for a 30-day trial period. The service has very broad functionality; the capabilities of the platform allow Infogram to compete even with such professional graphic editors, like Photoshop.

IN Google online service Charts can create almost any graph or chart. The tool also supports interactive dynamic charts. All graphics are created using HTML5/SVG, so no additional plugins are required to display information correctly. There is no simpler and convenient tool, if you want to create an interactive and scalable chart.

As you know, among GNU/Linux users there are quite a lot of people from the academic environment, that is, those people who observe, measure, calculate, compare and ultimately write scientific articles. This work usually involves graphical representation of information or visualization. In common parlance - by constructing graphs. It is about the programs intended for this that we will talk.

I compared 9 free software for visualizing two-dimensional and one-dimensional data. All of these programs are available on GNU/Linux, and many are available to users of other operating systems. All 9 programs allow you to build graphs that are not embarrassing to show or print. This is what is called “publication quality”.

The choice of programs is limited to those designed for visualizing one-dimensional or two-dimensional data. By one-dimensional (1D) data I mean a mapping from one one-dimensional set to another, e.g. functional dependence. By two-dimensional (2D) data I mean a mapping from a two-dimensional set to a one- or two-dimensional one, for example a functional dependence or a vector-valued function defined on a plane. In my opinion, visualization of one- and two-dimensional data is the most common task.

Programs focused primarily on visualizing multidimensional data are excluded from the comparison. However, all these programs deserve mention: OpenDX, VTK, MayaVi,. All this is interesting, but a completely different story. Also, programs for constructing graphs and other, exotic, visualization methods were not included in the comparison. Of these, graphviz and prefuse are worth mentioning.

So, the comparison involved:

• gnuplot- an industry veteran, so almost everyone who needs charts is familiar with it and can work with it; I myself use it with pleasure, because with just one or two short commands you can display the data reasonably well;
• Gri- a lesser-known project, actually a programming language for drawing scientific graphs; initially it was actively used to present geographical information, so there is complete order here with isolines and color maps;
• matplotlib- a relatively young, but rich in opportunities and actively developing project, is a library for Python language; matplotlib feature - syntax close to MATLAB; hence the second name of the project: pylab;
• PyX- another visualization package with using Python; the choice between matplotlib and PyX is largely a matter of taste, but it should be noted that some things are more natural to do in one, and others in the other (see table);
• Tioga— a library for the Ruby language that uses PDFLaTeX for drawing graphs; as a result, a high-quality result that pleases the eye, but a rather steep learning curve (in addition to mastering Ruby, you will need to understand Tioga itself);
• Ctioga— the same Tioga for those who want it now and immediately; graph parameters are set from command line, and Tioga is already used to draw it; Unfortunately, Ctioga is only suitable for one-dimensional data, but for them it can easily replace gnuplot;
• GNU plotutils- they are also the graph utility; Personally, I find its interface less intuitive and easy to use, and its capabilities more limited than other programs; however, the libplot library included in the same package may be interesting from the point of view of writing your own programs for plotting;
• plotmtv- is far from a new project, and, as it seems to me, is stagnating; copes well with two-dimensional scalar and vector data; main disadvantage: commands for plotting must be embedded in data files; but if you already have files in plotmtv format, it’s easy to build graphs, the quality is quite decent, and the main parameters of the graph can be changed using GUI;
• Grace- the only program among those considered in which you can completely control the construction of graphs using a graphical interface; unfortunately, that’s why I still haven’t managed to make friends with her; its capabilities are quite decent, but it is only suitable for visualizing one-dimensional data;

I personally have used and still use gnuplot, Gri, matplotlib, Tioga and Ctioga - and am happy with each of them. If you need to draw something quickly (for yourself), usually gnuplot, Gri or Ctioga are my choice. I also use Gnuplot if I need to draw the surface of a level. If you need to draw isolines or color maps from 2D data, Gri and Tioga do the job best. matplotlib can also do this, but I became familiar with it relatively recently and have only used it for various diagrams so far.

In comparison, perhaps, one could also add programs

Advanced Grapher is a function graphing program. The utility plots a function specified by the user. The application can build functions Y(X), X(Y) in Cartesian coordinates, in the polar coordinate system - R(a), parametric equations - X(t) and Y(t), equations and inequalities, direction field - dy/dx and dx/dy, and also draw graphs using a table. With the Advanced Grapher program it is possible to: calculate tangent and normal equations, find derivatives, zeros and extrema of functions, search for intersection points of graphs and numerical integration. At the same time, the program can build up to 30 function graphs. The program implements the function of printing, saving function graphs to a file and copying them as images to the clipboard.

Function graph program

Function graphs are scaled, you can set the color and thickness of lines for plotting, the application supports transition to " full screen". The program has a help file that makes it easier to work with Advanced Grapher. The developer offers to use the program for free if the user chooses the Russian interface language and uses the utility for non-commercial purposes.
