Origin is a software for data analysis and drawing, which has the functions of statistics, peak analysis and curve fitting, and can draw two-dimensional and three-dimensional graphics. Support Excel data import, even txt (directly drag txt data files into Origin. However, the compatibility of Origin with Chinese is not particularly good, and this method is not efficient. The interface is pure English, but don't be scared by appearances. There are not many functions used at ordinary times. As long as you know what those commonly used functions are, you can get started quickly. Do not require every function, just meet your own needs. The following is the working interface of Origin:

Add your own data in the red box to explain:

The reason for this explanation is that after you enter the content first, you don't have to change the icon, but you can do it at once. Other places basically don't need too much explanation, and everyone can have a general understanding by groping. Then you can analyze and draw the corresponding imported data.

When drawing, people who come into contact for the first time will find that they are not drawing a closed coordinate, or there are only two or three coordinate axes, and one or two sides cannot be closed, but what should I do if I want to get a closed figure? Some students may notice that there is a drawing tool next to them, so they may draw with straight lines. I tried to add axes manually, but it was also clumsy. Later, after the guidance of a brother, I finally figured it out. Do closed coordinates, put the ruler inside the coordinate axis, and you can find &; Solve it in format. In addition, the numerical range can be changed in proportion to draw a more convincing chart.

Back to the topic, how to turn the left picture into the right picture? In fact, the operation is relatively simple. Double-click or right-click on the coordinate axis and change it in the pop-up dialog box. Take adding top coordinates as an example:

Generally, the font of the chart should match the font of the paper. The default font of Origin is Arial Unicode MS, which does not meet our requirements. What should I do if I want to change to a font that matches my paper? It's too cumbersome to select the font before using it on the toolbar. Is there a better way to use it? Yes! As long as you set it once, the font behind it doesn't need to be modified. Take the font set by yourself as an example, and the settings are as follows:

Some people may ask, English and numbers in Times New Roman format meet the requirements, but can't Chinese characters use this font? The answer is yes! If in doubt, you can try. There is almost no difference between Chinese characters in Times New Roman format and Chinese characters in Song Ti format. In other words, setting Chinese characters to Times New Roman font has little effect.

The source words blend well. You can copy the original image directly into Word, and double-click the image to edit it. But the problem is coming again. Careful classmates will find that there are many blanks on the edge of the origin map, which leads to a large picture size and a large space occupation. What should I do if I drag the reduction directly? Some students probably thought of screenshots, but what they cut out was pictures, so they can't edit the content any more. If there are mistakes in it and you want to modify it, it is estimated that someone is going crazy!

In fact, the extra blank is not the problem of the origin map, but the problem of the default setting. You can completely eliminate the extra white space by changing only one setting. In addition, it would be better if you change the settings next to the font above. Although it is set in one place, it is explained separately from the above in order to let everyone know why they still know. These settings are as follows:

If there is a one-to-one correspondence between independent variables and dependent variables (like the legend above), just draw them directly. But if an independent variable corresponds to two or more dependent variables, such as the following graphs with two Y axes and three Y axes, how to draw them? It is estimated that some people will be puzzled. But it's not difficult!

The drawing method is to add a y-axis layer. If double Y-axis is needed, add another Y-axis on the basis of the previous one. If you need three Y-axes, please add another layer, and so on ... Take double Y-axes as an example, as follows:

Sometimes I accidentally lose the data, leaving only the origin map (it's an origin map file, not a map that can't be edited, so I can't extract it), or I want to extract some data from the origin map. What should I do? Powerful Origin can also do it, ensuring that your data will not be lost. The method of operation is not difficult:

Origin doesn't need to spend too much time studying, just master the basic drawing skills and meet your own needs.
