How to display graphically

Hello

I want the conditions of an issue to be graphically displayed at each step of the program. For example, in the case of a River crossing puzzle, I want to show which people (variables) are on which side of the river at each step.

Thanks

What data you have? You can display that using plot with some markers color depending on people are on which side.

In this case we have eight people

I considered each side an 1*8 representation

We move people according to the input received from the user

For example, if the first 2 people go from left to right, the situation will be left

001111111

The position will be on the right

11000000

How can I graphically show this situation now?

not sure this is what you had in mind ...

%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=[0 0 1 1 1 1 1];
right= [1 1 0 0 0 0 0 0];

% 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
scatter(pL(:,1),pL(:,2),'filled','SizeData',200)
alpha(.5)
scatter(pR(:,1),pR(:,2),'filled','SizeData',200)
alpha(.5)

the output looks like this

Thank you Thank you

This is exactly it

Thank you very much

Is it possible for each point to have a specific color ??

[Nora Khaled]

you could plot them in a loop like

for i=1:1:nL
    scatter(pL(i,1),pL(i,2),'filled','SizeData',200)
    alpha(.5)
end

for i=1:1:nR
    scatter(pR(i,1),pR(i,2),'filled','SizeData',200)
    alpha(.5)
end

in this case you will not need the alpha(.5) to change the transparency.

Thank you very much

[Nora Khaled]

you're welcome

[lech king]

Thank you for your help

In this case, each point indicates an independent person. Is it possible that each person has a unique shape ??

For example, the first person is a triangle and the second person is a square and .......

[Nora Khaled]

Yes

shapes=['o' '+' 's' 'd' '.' '>' 'x' '*' '^'];

for i=1:1:nL
    scatter(pL(i,1),pL(i,2),shapes(i),'SizeData',200)
    alpha(.5)
end

for i=1:1:nR
    scatter(pR(i,1),pR(i,2),shapes(i+nL),'SizeData',200)
    alpha(.5)
end

However, in this case you can not use the property filled.

you can see all shapes avalible here:

That's it

Thank you very much for your kindness

[Nora Khaled]

Sorry, I just realized... this just control the shape of the plot but does not mean that if a circle person moved from the left to the right that person will remain a circle.

If you want to assosiated the shape with the person... try this

shapes=['o' '+' 's' 'd' '.' '>' 'x' '*' '^'];

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

hope it helps.
