(1)Powerpoint/Visio. Both are Microsoft software. Visio is best suited for block diagrams. But because it is not the basic software of office, most computers are not installed. You can use Powerpoint instead.

(2) Origin. This is a data analysis and drawing software developed by OriginLab. Easy to learn, powerful, and can easily make expert maps. The generated images can be exported to more than ten file formats such as bmp, eps, pdf, png and jepg. Ideal for drawing curves, surfaces and other numerical results.

(3)MATLAB. This is an aircraft carrier-level software. Strong data processing ability and excellent presentation ability can make you do almost anything. But to use it, we must first learn to program with MATLAB. If you don't have any foundation, but you really want to use it to draw pictures, here is a simple learning method.

First, use the plot command to draw a picture. For example: plot(x, y); %x represents x-axis data and y represents y-axis data. If you don't know this yet, you can look at the help that comes with MATLAB, which is very detailed.

Then use the editing function in the drawing window, add coordinate labels, check boxes and so on.

When you are satisfied with the drawing, use the menu file->; The generateMfile function generates an m file.

In the m file, you can see which commands are used to control which part of the picture. Using this M file as a template, you can get an ideal picture by replacing tags and data in the future.

How to draw beautiful illustrations in papers? The reason why scientific research drawing is a major that cannot be underestimated is that scientific research drawing is not a painting that emphasizes beauty and perception, but communicates with scientific research colleagues and the public in the form of images with many scientific research concepts and ideas that cannot be described in many languages. Although it is an image, it is actually a research result. Since it is a professional research achievement, there are usually many researchers in the same field who have images with the same structure in periodicals or special books. Before preparing the drawings, they should try to collect more than two published reference drawings (1). (2) Go to the online gallery or the scientific research drawing platform to be introduced in the next paragraph, and search for available drawings through keywords; (3) Determine the size of the picture to be drawn this time; (4) consider whether color is needed or black and white is better; (5) Draw a sketch of real size. If you are a master of hand-drawing, maybe when all kinds of drawing software are not very convenient, you can use hand-drawn images directly.

Many outstanding scientists are quite artistic, and Leonardo da Vinci is the representative. Looking back at the pictures of animal cells, human organs, plant vascular bundles, pictures of various viruses and DNA double helix seen in biology textbooks, it is not easy to draw these pictures beautifully and professionally. However, it is not difficult for scientists to convey new concepts or research results with images, because free or reasonable scientific research illustration drawing platforms and drawing software have sprung up. In addition to Canva and Pictochart, which are very useful in designing presentations and posters, there are many scientific drawing artifacts that researchers can't miss:

With 200,000 users, Biorender:Biorender is an online scientific research drawing platform tailored for more than 30 disciplines related to life sciences, with more than 20,000 free pictures. The latest coronavirus pneumonia-19 theme is also provided with professional pictures. As long as you have the intuition to use PPT, you can get started and provide free professional and paid use solutions. You must not miss it!

Edraw, a major in science and engineering, provides pictures commonly used in physics, mathematics and chemistry in the form of App, such as lenses, light sources, waves, molecular diagrams, chemical tests, laboratory equipment diagrams, circuit diagrams, 3D geometry, analytic geometry and so on.

Little painter in scientific research: Do you remember the little painter software in the era before Photoshop appeared? This is the free use of scientific research professional painters, who can freely illustrate, cut and adjust the size of pictures, increase the hand-drawing function, and have online communities to discuss intractable diseases in scientific research drawing.

Chart expert: For people who are used to Word, it's like making a special chart word processing page. Registration is free, with business, engineering, software and other processes and system diagrams, which can save a lot of time.

Professionals who draw scientific research illustrations need to have a university-level scientific research background, as well as the artistic ability of illustrations or designers. In North America, at present, a few colleges and universities offer professional degrees in scientific research and drawing, and the number of graduates in one unit may be less than 10. In this era of image information explosion, there are more and more job opportunities in the new field of scientific research and drawing. Slash youth with scientific research and artistic background may wish to give it a try.

How to draw beautiful illustrations in papers? Six key points allow you to effectively present charts in scientific research papers.

Charts in scientific research papers are the most intuitive way to show research results. Tables and pictures can express some complex information more clearly and intuitively. Clear, intuitive and correctly expressed pictures will enhance the persuasiveness of the article, and its effect is often better than that of a long paragraph of text description.

Nowadays, many journals have clear requirements on the resolution, format and text labeling of pictures. Therefore, after the target journal is determined, the pictures of the articles should be modified according to the submission instructions of the journal.

Tools for processing photos

The pictures in the article generally come from photos, graphics made by drawing software or mathematical processing software. Using appropriate tools to deal with different types of diagrams can achieve twice the result with half the effort. Tools for processing photos, heavyweight are

. Because it is not only a very powerful open source software, but also supports the import and export of various formats. Commonly used mathematical processing software are MatLab and Origin. Origin can make very professional graphics. Of course, Excel is also a good choice. Flowchart can meet almost all the requirements of Visio or PPT.

In the use of pictures, there are some places that are prone to problems, which need to be noted:

Make sure that the information provided by each chart is clear and credible. The original images obtained in the experiment must be preserved for a long time. All modifications and adjustments in the later period shall not distort the image or affect the authenticity of the original image. The modified image can only be saved as other files. Do not overwrite the original image.

Photographs should pay attention to the intake of reference objects, the background is clean, and the higher the resolution, the better. Don't shoot against the light.

The picture is concise and to the point. Try to delete unnecessary words in the picture. Fonts, labels and abbreviations used in charts must be consistent. In addition, the picture should be consistent with the text description in the article. In the process of modifying the article, it is easy to change the label of the chart, and there will be inconsistencies, which need special attention.

Use charts or tables? It is best to use tables for less data and graphs for more data. The comparison of trends is more suitable for charts than tables. In terms of expression, try to use the most compact format, that is to say, the same data information should be expressed in a diagram or a table, and never use both to cause repeated expression. When building a data table, we should weigh the integrity and importance of the data, and don't make the table too complicated. If necessary, a large data table should be divided into several small tables by type, so that when readers read it, important data can be seen at a glance.

Reasonable explanation. Each chart and table should have a brief description. Even if readers don't look at the content of the article, they can get some useful information only through charts and their notes. In the body of the article, you need to quote some key data in the chart, but don't list all the data in the table repeatedly.

No matter what kind of pictures have high resolution, they should be printed clearly enough. Many academic journals require 600dpi, which is also the highest resolution of printers.

Other small details:

Coordinate labels and units should be accurate.

The text in the picture should be the same size.

Different curves in the same picture should be distinguished by different lines or marks.

When distinguishing by color, we should pay attention to whether black and white can be distinguished clearly after printing. The background of the picture is preferably white, and other colors may look better on the screen, but the printed effect will not be very good.
