Please find the below examples that explain the use of legends in Matlab: To plot two lines and display the legend in the present chart. plot(a,y) The properties that legends do not share with axes are: You can use a legend's handle to set text properties for all the strings in a legend at once, rather than looping through each of them. . In the above example, another line is added to an existing plot using the legend label in the plot command as shown in the highlighted part. Then, add a legend. Is it possible to define, that the legend will have an calculated data in it? MATLAB displays only one legend per axes. To plot two lines and display the legend in the present chart. When plotting filled areas (patch or surface objects), the legend contains a sample of the face color next to the text label. refreshes the specified legend. MATLAB provides us with plenty of functionalities, useful in various computational problems. >> Legend=zeros(1,10); >> Legend(1,8) = 'test' Subscripted assignment dimension mismatch. toggles the legend on or off. Double-clicking a label allows you to edit the label. You can move the legend by pressing the left mouse button while the cursor is over the legend and dragging the legend to a new location. y2 = sin(3*a); legend legend positions the legend based on a variety of factors, such as what objects the legend … As we have learned in our previous articles, we can create vector plots in MATLAB using the ‘plot’ function. makes the legend in the current axes or the axes specified by axes_handle visible. legend places a legend on various types of graphs (line plots, bar graphs, pie charts, etc.). with no arguments refreshes all the legends in the current figure. Graphs are the graphical form of the explained data in the data set. leg1=legend(legend); ... here's an updated solution for Matlab r2020b or later. legend installs a figure ResizeFcn, if there is not already a user-defined ResizeFcn assigned to the figure. legend(string_matrix) orientation can be vertical (the default) or horizontal. In this article, I cover the basic use of the legend() function, as well as some special cases that I tend to use regularly.. This ResizeFcn attempts to keep the legend the same size. plot ([1, 2, 3]) ax. legend (['A simple line']) Plot legend below the plot. hold on Location is one of the main property of the legend which decides the location of the legend. 转自:http://blog.sina.com.cn/s/blog_7db803c10102weyk.html Matlab中legend默认的位置在NorthEast,如图所示: 然而,我们却可以通 For each line plotted, the legend shows a sample of the line type, marker symbol, and color beside the text label you specify. 用Matlab画图时,有时候需要对各种图标进行标注,例如,用“+”代表A的运动情况,“*”代表B的运动情况。 legend函数的基本用法是: LEGEND(string1,string2,string Specify the legend labels as inputs to the legend function. a = linspace(0,2*pi); legend('toggle'), legend(axes_handle,'toggle') y = sin(a); Create a figure with a line chart and a scatter chart. In the above example, the legend for the two lines is shown in the top right corner of the plot, one line depicting the values for the function sin(a) and the other line depicting the values for the function sin(2a). For example: ax. legend(...,'Orientation','orientation') By closing this banner, scrolling this page, clicking a link or continuing to browse otherwise, you agree to our Privacy Policy, New Year Offer - MATLAB Training (3 Courses) Learn More, 3 Online Courses | 1 Hands-on Project | 8+ Hours | Verifiable Certificate of Completion | Lifetime Access, R Programming Training (12 Courses, 20+ Projects), All in One Data Science Bundle (360+ Courses, 50+ projects).

DisplayName 속성을 원하는 텍스트로 설정하여 플로팅 명령 중에 범례 레이블을 지정합니다. In this article, we will learn how to put Legends to the plots created in MATLAB. Three years ago I explained how we can use a couple of undocumented hidden properties of the legend in order to add a legend title (the legend object had no Title property back then – this was only added in a later Matlab release, perhaps as a result of my post). legend('boxoff'), legend(axes_handle,'boxoff') For each legend, there is a legend key that is linked to every data displayed in the chart. The legend function in Matlab creates a legend in the current axes of the current figure. If no legend exists for the current axes, one is created using default strings. hold on There are various properties of the legend in Matlab which are discussed below. Luckily, MATLAB/Octave include the legend() function which provide some flexible and easy-to-use options for generating legends. By default, the legend annotates the current axes. Legends can be used in various graphs or charts like a bar graph, line graph, pie chart, etc. ALL RIGHTS RESERVED. Otherwise, legend constructs a sting of the form data1, data2, etc. plot(a,y1) ... MATLAB displays only one legend per axes. Introduction to MATLAB Plot legend. Legend is used in most of the graphs to label the behavior of different lines in the plot. creates a legend with the legend items arranged in the specified orientation. 플로팅 명령 중에 범례 레이블 지정하기. Plot two lines. legend(h,string_matrix) ts me again with an maybe simple question for you. Añada una leyenda con una descripción para cada gráfica. Create a figure with a line chart and a scatter chart. legend('off'), legend(axes_handle,'off') [legend_h,object_h,plot_h,text_strings] = legend(...) legend(li_object,M) Especifique las etiquetas de la leyenda como entradas para la función legend. Specify the legend labels as inputs to the legend function. 그런 다음, 범례를 추가합니다. legend(li_object,string1,string2,string3) returns the handle to the legend on the current axes or empty if no legend exists. end. Add a legend with a description for each chart. % Plot random data in each subplot. Learn more about plot, legend MATLAB How to modify the legend in MATLAB ® graphs. The axes of a plot are a separate object in Matlab, and can be controlled by using set, get and other commands. In this example, we have added another line to the existing line as mentioned in the above example. y1 = sin(2*a); Using one of the ...Outside values for location assure that the colorbar will not overlap the plot, whereas overlaps can occur when you specify any of the other cardinal values. creates a legend for legendinfo objects li_objects with strings string1, etc. There are many other locations apart from this which are also used in Matlab. legend(target,___)给特定轴添加图例; % Create a figure with two subplots and return the two Axes objects, ax1 and ax2. any help will be greatly appreciated :) legend('string1','string2',...) Legend Position on a plot. Here we discuss the introduction and working of Matlab Legend with examples. legend('sin(a)','sin(2*a)') displays a legend on the plot containing the objects identified by the handles in the vector h and using the specified strings to label the corresponding graphics object (line, barseries, etc.). returns. ... Bug and workaround in timeseries plot – Matlab's internal hgconvertunits function has a bug that affects timeseries plots. uses location to determine where to place the legend. x = linspace (0,pi); y1 = cos (x); plot (x,y1, 'DisplayName', 'cos (x)' ) hold on y2 = cos (2*x); plot (x,y2, 'DisplayName', 'cos (2x)' ) hold off legend. x = linspace (0,pi); y1 = cos (x); plot (x,y1, 'DisplayName', 'cos (x)' ) hold on y2 = cos (2*x); plot (x,y2, 'DisplayName', 'cos (2x)' ) hold off legend. Add a legend to a graph showing a sine and cosine function: In this example, the plot command specifies a solid, red line ('-r') for the cosine function and a dash-dot, blue line ('-.b') for the sine function. legend('sin(a)','sin(2*a)'). location can be either a 1-by-4 position vector ([left bottom width height]) or one of the following strings. . By default, the legend annotates the current axes. associates each row of the matrix string_matrix with the corresponding graphics object in the vector h. legend(axes_handle,...)
