Aiming at the problem that plot3 function drawing in MATLAB only outputs points instead of line

项目场景：

• Data processing stage mapping stage

---

问题描述

• In the MATLAB environment plot3 plot output is only points rather than lines

• figure
  for i6=1:step
   
  plot3(DiscretePoint_CP{i6,1}(1,1),DiscretePoint_CP{i6,1}(2,1),DiscretePoint_CP{i6,1}(3,1),'ro')
  hold on
  grid on
  
  end

---

原因分析：

• The plot3 function under the for loop is a dot - by - dot plot

---

解决方案：

• The drawing data is stored as an array, and the plot3 function is directly used for array drawing without using for loop

• for i11=1:50
      
  X_point(i11,1)=DiscretePoint_CP{i11,1}(1,:);
  Y_point(i11,1)=DiscretePoint_CP{i11,1}(2,:);
  Z_point(i11,1)=DiscretePoint_CP{i11,1}(3,:);
  
  end
  plot3(X_point(:,1),Y_point(:,1),Z_point(:,1),'r-')%
