How to draw Violin Picture by Matlab
This article mainly shows you "how Matlab draws violin pictures". The content is simple and clear. I hope it can help you solve your doubts. Let the editor lead you to study and learn this article "how to draw violin pictures in Matlab".
1 the basic use of the example, Y is the matrix Xuan 1, Hdl1=violinChart, [0 0.447 0.741], 6)
X: Abscissa
Y: dataset
FaceColor: color, example is [0 0.447 0.741]
Width: the width of the violin picture, which is 0.6, that is, the upper limit of the probability density is 0.6 times the distance between two violin pictures.
For basic use, Y is a vector, X is the tag X = [1.*ones (1Magi 50), 2.*ones (1Mague 30), 3.*ones (1Mague 20), 4.*ones (1Mague 50), 5.*ones (1Magazine 50)]; Y=randn (1200) + sin (X); Hdl=violinChart (gca,X,Y, [0 0.447 0.741])
Base on using multiple images and add legend X1 = [1 cos 2) + sin (X1); X2 drawing 2) + cos (X2); figureHdl1=violinChart (gca,X1,Y1, [0.447 0.741]); Hdl2=violinChart (gca,X2,Y2, [0.850 0.325 0.098]); legend ([Hdl1.F_legend,Hdl2.F_legend], {'randn+sin (x)', 'randn+cos (x)'})
