Editor to share with you Matlab how to draw scatter density map, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to understand it!

Effect.

The principle is also very simple: get the density of each point of the mesh through the ksdensity of matlab, fit the surface through the density, then calculate the corresponding probability of each data point, and map the probability to the color.

In case you can't find the function, the tool function will be put at the front this time.

1 the complete code of the tool function function [CData,h,XMesh,YMesh,ZMesh,colorList] = density2C [XMesh,YMesh] = meshgrid (XList,YList); XYi= [XMesh (:) YMesh (:)]; F=ksdensity ([Xpencil Y], XYi); ZMesh=zeros (size (XMesh)); ZMesh (1:length (F)) = Fentinh interp2 (XMesh,YMesh,ZMesh,X,Y); if nargin
