Today, Xiaobian will share with you the relevant knowledge points on how to draw violin diagrams based on Matlab. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you will gain something after reading this article. Let's find out together.

How to use violinChart

Write a matlab drawing violin diagram function:

1. The fiddle-shaped region in the figure is a nuclear density curve.

2. White squares are 25%, 75% quantiles.

3. The middle line is the median.

4. White points are outlier points.

5. The vertical black lines are the upper and lower limits of the points after removing outliers.

Base usage, Y is matrix X=1:5;Y=randn(100,5);violinChart(gca,X,Y,[0 0.447 0.741], 0.6);

X |abscissa.

Y |Data sets.

FaceColor |The color, for example, is [0 0.447 0.741].

width |The width of the violin graph, which is 0.6 here, is 0.6 times the distance between two violin graphs as the upper limit of the probability density of 1.

Base usage, Y is vector, X is label X=[1.* ones(1,50),2.* ones(1,30),3.* ones(1,20),4.* ones(1,50),5.* ones(1,50)];Y=randn(1,200)+sin(X);violinChart(gca,X,Y,[0 0.447 0.741]);

Basic use, multiple images drawn, and add legend X1=[1:2:7,13];Y1=randn(100,5)+sin(X1);X2=2:2:10;Y2=randn(100,5)+cos(X2); figureHDL1 =violinChart(gca,X1,Y1,[0 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)'});
