Is figdraw donation export permanent?
Yes. The opportunity to export is limited. Once exported, it is permanent. As long as it is exported through formal channels, it will be automatically authorized. There is no need to worry about any risk of infringement or retraction. Figdraw donation export is permanent. Figdraw is the first open online scientific research drawing platform in China. Anyone can use the original materials on the platform to recreate. It is suitable for paper illustrations, magazine covers, medical illustrations and more scenes. How to draw beautiful illustrations in papers
The reason why scientific research drawing is a profession that cannot be underestimated is because scientific research drawing is not a painting that emphasizes beauty and perception, but combines scientific research concepts and many words that cannot be described The ideas are communicated with research peers and the general public in the form of images. Although they are images, they are actually research results. Since it is a professional research result, there are usually many researchers in the same field who have images with the same structure in journals or special books. Before preparing the drawing, you should try to (1) collect more than 2 published reference images; (2) ) Go to the online gallery or the scientific research drawing platform introduced in the next paragraph, and search for available pictures with keywords; (3) Decide the size of the picture you draw this time; (4) Consider whether color is needed or whether black and white is better, (5) )Draw an image at its true size. If you are a hand-drawing expert, you may be able to directly use hand-drawn images if you are not comfortable with various drawing software.
Many outstanding scientists have artistic talents, and Leonardo da Vinci is a representative figure. Think back to the animal cell diagrams, human organ diagrams, plant vascular bundle diagrams, and various diagrams you saw in biology textbooks. Pictures of various viruses, as well as DNA double helix diagrams, it is not easy to draw these patterns beautifully and professionally, but in today's world where image communication media is changing with each passing day, it is not difficult for scientists to convey new concepts or research results through images. , because free or reasonably priced scientific research illustration drawing platforms and drawing software have mushroomed in the scientific community. In addition to Canva and Pictochart, which are very useful for designing presentations and posters, there are also many scientific research drawing artifacts that scientific researchers cannot miss:
Biorender, which has 200,000 users: Biorender is used for more than 30 types of life science related Xuemen's tailor-made online scientific research drawing platform has more than 20,000 free pictures. The latest COVID-19 theme also has professional pictures available. As long as you have the intuition to use PPT, you can get started. It provides free to professional and paid usage plans. It is absolutely Don't miss it!
Edraw for science and engineering: Provides commonly used pictures in the three fields of physics, mathematics, and chemistry in the form of App, such as lenses, light sources and waves, molecular diagrams, chemical tests, and laboratory equipment illustrations. Circuit diagrams, 3D geometry, analytical geometry, etc. are all available.
Scientific Research Painter: Do you still remember the Little Painter software in the era before Photoshop appeared? This is a free scientific research professional painter. You can freely insert pictures, crop and resize pictures, and add hand-painted pictures. function, as well as an online community to discuss the intricacies of scientific research drawing.
Diagram Expert: For people who are accustomed to using Word, this is like a word processing layout dedicated to charting. It is free to register and has various process and system base diagrams for business, engineering, software, etc., 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 art ability of an illustrator or designer. In North America, a few universities currently have special scientific research drawing degrees. The unit may only have less than 10 graduates a year. In this era of explosion of image information, job opportunities in the emerging field of scientific research and drawing are growing. Young people with a background in scientific research and art may wish to give it a try. Graphpad, a beginner’s study of the classic drawing tool
Most scientific research articles are inseparable from graphs, especially graphs. Being familiar with some graphing software and displaying graphs in articles and PPT is an important part of scientific research training. . Beautiful articles with pictures can add a lot of points to your work. Shengxinbaodian launched a series of R tutorials called ggplot2 Efficient and Practical Guide (visual scripts, tools, routines, color matching) to explain how to draw high-looking pictures through R language.
Later, in order to make it more convenient to use, the Shengxin Baodian team developed an online drawing tool that supports 14 common graphics and partial amplicon analysis. It is very popular, with an average of 400 visits per day and hundreds of thousands of visits in total, covering all continents of the world. Functions are also constantly being added and improved.
Many friends in the background said that there is a need for more drawings, so I organized the use of
Graphpad
. One is to spread knowledge, and the other is to introduce excellent software to Learn to make online drawing better and better.
Graphpad, Origin and SigmaPlot
They are three statistical drawing software commonly used in scientific research. They each have their own advantages and disadvantages and often need to be used together.
Today I will introduce to you the basic use of Graphpad
The following is the welcome interface of Graphpad
From
Box 1< /p>
It can be seen that GraphpadPrism6 provides users with
6 kinds
basic statistical chart choices;
Box 2
is an explanation of the selected type of chart, click Learnmore to view the official help document;
Box 3
You can select a subcategory under a certain type of chart;
Box 3
p>
Box 4
A demonstration data set is provided to facilitate novices to get started.
The description of the 6 statistical chart types and the statistical methods used are introduced below:
Select the second ready-made data set provided under grouped for charting demonstration. After selecting, just click create.
After the previous step, we entered the main interface of graphpad operation.
Box 1
displays our data. Each large group represents Three different cell lines (wild-type cells, GPP5cellline and GPP7cellline); each row represents a different treatment (serum starvation and normal culture); each group has 5 parallel replicates.
There are missing values ??in this experimental data, such as A:Y4 in the first row.
Box 2
There is a
Directory tree
After importing the data, click Graphs to output the graph, as follows:< /p>
In this interface, you can change the type of graph according to your own needs. Beginners should dare to
make some mistakes
and try different options on their own to know the function of each part. (Try to find out the truth)
The preliminary statistical chart above does not show the statistical analysis results such as the differences between groups, so how do we add * to show the differences between groups?
There is an enterandploterrorvaluesalreadycalculatedelsewhere option on the welcome interface, which indicates that statistical analysis results done elsewhere can be imported from the outside. Does that mean that you have to do the calculations elsewhere and then draw the graph?
No! Because it can be done on Graphpad. Do statistical analysis directly!!! Although you can do the analysis elsewhere, it is not recommended. It is more convenient to do it directly.
First determine the goals of our analysis:
1) Assess whether differences between cell lines are greater than expected;
2) Assess whether differences between treatments More than expected by chance;
3) Assess whether differences between treatments are consistent with each cell line;
4) Calculate 95% confidence in differences between cell lines with different treatments interval.
So we need to perform
two-factor analysis of variance
, click Analyze, select Two-way ANOVA from the Grouped analysis list, and accept the dialog box All default options. The user-friendliness of Graphpad is that it will automatically identify the data structure of the current analysis and show the user the optimal default analysis options.
The subsequent specific analysis will require a certain amount of statistical knowledge. Don’t be afraid of trying it. You will find that when you click on different options, the icons will change accordingly, which is very convenient for users to understand.
1) The first part: Experimental design. It is mentioned at the beginning that this set of data is unpaired, so choose the first one;
2) The second part: Multiple comparison selection, which is what you want Do you want to compare horizontally, vertically or diagonally;
3) Part 3: Select some parameters for statistical analysis.
After setting all the above, click OK. The analysis results will be displayed on the main operation interface and saved to the Results folder under the directory tree on the left.
1. Introduction to the graphics editing toolbar
1) Part 1: Document operation module, similar to office, such as opening, creating, saving, copying and pasting, etc.;
< p>2) The second part: data analysis, that is, the statistical analysis of the input data demonstrated previously;3) The third part: graphic editing, this part is the essence of the software. You can edit and change graphics such as graphic type, coordinate axes, error bars, graphic size, color, etc.;
4) Part 4: Text editing, you can illustrate lines, add text, etc. on statistical charts;
5) Part 5: Graphic output, you can export, print or output the completed graphics to word/PPT.
2. Based on the previous statistical analysis results, use text editing tools to add signs of differences between groups to the statistical charts
1) draw: You can insert lines of different shapes;
2)write: edit text, insert formulas, etc.;
3) Double-click any element in the graphic to edit the shape, size, thickness, etc. of text, lines, etc.
3. Coordinate axis adjustment
Click on the
second icon in Change
, or double-click on the picture
Coordinate axis
, call up the coordinate adjustment tool;
The overall setting of the coordinate axis and the X-axis setting, see the diagram, generally do not make too many changes;
Key points Explain how to set the Y-axis and make a
truncated graph
, which is a common problem in statistical graphing.
The previous data was not very different and not suitable for demonstration, so another histogram was generated. The value of the column on the left is too large, the value of the column on the right is too small, and the column on the right almost disappears, making the graph look very uncoordinated. Making a
truncated graph
can solve this problem very well.
1) Click LeftYaxis in the coordinate settings (generally, only the left Y-axis is generated by default for drawing);
2) Select Twosegments at GapsandDirection, which will break the Y-axis into two parts ( According to the actual data, you can also choose to break the Y-axis into 3 segments);
3) At Segment, set the parameters (Rang) for the Y-axis of the lower segment (Bottom) and upper segment (Top) respectively;< /p>
4) Then set the Y-axis value label at the Majorticksinterval under Regularlyspacedticks;
length: 50%, half the length of the upper and lower segments;
minimum: lower segment Minimum value 0, minimum value in the upper section 150;
maximum: maximum value in the lower section 10, maximum value in the upper section 200;
Majorticks: size of each grid in the lower section is 2, size of each grid in the upper section is 10 .
In this way, the middle part of the Y axis 10-150 is cut off, and the whole picture looks much better.
4. Color modification
Click the
last icon in Change
, or in the picture
Double-click the column
to bring up the tool box for adjusting parameters;
The basic operations of using graphpad to make statistical charts are probably the above. It is not difficult to master the use of a tool. You will know if you try more. The difficulty lies in the statistical knowledge behind it. How to choose the appropriate statistical analysis method for your own data? Once you understand which data structures are suitable for different analysis methods, you can draw inferences from one example and conduct appropriate analysis on the data of different experimental designs.
