How to graphically represent man in MATLAB

Hello

I implemented the river problem in MATLAB and used the following function to graphically represent this problem (which Nora Khaled was kind enough to draw for me).

As you can see, people are represented in the problem with these shapes

shapes=['+' '^' 'x' 's' '*' 'd' '|' '_'];

I wanted to ask if it is possible to present this issue in a better way and with better symbols ??

function[]=Enve(A,B)

%Environment

envSize=4;

figure;

x=-envSize:0.1:envSize;

y=.5*sin(x);

plot(y,x,'lineWidth',10)

axis([-envSize envSize -envSize envSize]);

hold on;

%Input

left=A;

right= B;

% number of ppl

nL=sum(left);

nR=sum(right);

%random position for ppl

maxX=envSize-1;

minX=2*max(y);

maxY=envSize-1;

minY=-(envSize-1);

pL = [-(minX + (maxX-minX) .* rand(nL,1)), (minY + (maxY-minY) .* rand(nL,1))];

pR = [(minX + (maxX-minX) .* rand(nR,1)) , (minY + (maxY-minY) .* rand(nR,1))];

% plot

shapes=['+' '^' 'x' 's' '*' 'd' '|' '_'];

leftcounter=1;

rightcounter=1;

for i=1:1:nL+nR

if left(i) ==1

scatter(pL(leftcounter,1),pL(leftcounter,2),shapes(i),'SizeData',200)

alpha(.5)

leftcounter=leftcounter+1;

else

scatter(pR(rightcounter,1),pR(rightcounter,2),shapes(i),'SizeData',200)

alpha(.5)

rightcounter=rightcounter+1;

end

end
