Hello guys first of all, i need to plot a seesaw like can be seen below with red and i need to move it like the blue one;

_ Code Fixed and now can runable_*

Here is what i done so far but its not works like i want

cubukuzunluk = 800;
x1uzak=300;
y1uzak=50;
dongu = 90;
dongu2=dongu;
tana=0;
alfa=0;
degisy=0;
dikdegisx=0;
yukselme=0;
    F(dongu) = struct('cdata',[],'colormap',[]);
for j = 1:dongu
    clf
   axis([-cubukuzunluk/2-100 cubukuzunluk/2+100 -50 250])
 superhesaplamalar= j +5;
 if j < dikdegisx
 yukselme = j
 end
hold on
plot([-50,50,-50,0,0,50],[0,0,0,100,100,0])
hold on
%sağa eğilme
plot([cubukuzunluk/2,-cubukuzunluk/2],[100-superhesaplamalar,100+superhesaplamalar])
%sola eğilme
%plot([250,-150],[100+superhesaplamalar,100-superhesaplamalar])
hold on
%kutu 1 çiz sol tarafa
plot([-x1uzak-25,-x1uzak+25,-x1uzak+25,-x1uzak-25,-x1uzak-25],[150+superhesaplamalar,150+superhesaplamalar,100+superhesaplamalar,100+superhesaplamalar,150+superhesaplamalar])
    drawnow
    F(j) = getframe;
end

We cannot run your code, e.g. because "dongu", "cubukuzunluk" and "dikdegisx" is undefined. You do not explain, what is not working as expected and the 2 images do not clarify exactly what you want. I do not see a chance to guess, how your code should be changed to satisfy your need.

Please post details. Do this by editing the question, not by adding a comment or answer.

Ty Jan, code is now runable, "dongu"---->loops "cubukuzunluk"---->the length of seesaw arms ""dikdegisx""----> tryed something with angles but thats not important

Hello Dear,

Use this code. If you want make necessary changes as per your requirements.

 clc;
close all;
clear all;
axis([-2 12 -5 5]) 
xt = [1 0 0 1];
yt = [1 1 0 0];
hold on
t = area(xt,yt);
hold off
disp('Do you want the object to slide?');
ip=input('1. Yes     2. No');
if ip==1 
figure, 
axis([-2 12 -5 5])
xlabel('X data')
ylabel('Y data')
zlabel('Z data')
legend('Data A','Data B')
%grid on
az = 0;
el = 90;
view([az,el])
degStep = 45;
detlaT = 0.1;
fCount = 71;
f = getframe(gcf);
[im,map] = rgb2ind(f.cdata,256,'nodither');
im(1,1,1,fCount) = 0;
k = 1;
% spin 45°
for i = 0:degStep:45
  az = i;
  view([az,el])
  f = getframe(gcf);
  im(:,:,1,k) = rgb2ind(f.cdata,map,'nodither');
  k = k + 1;
end
xt = [1 0 0 1];
yt = [1 1 0 0];
hold on
t = area(xt,yt); 
hold off
for j = 1:0.01:10
    xt(1) = xt(1)+0.01;
    xt(2) = xt(2)+0.01;
    xt(3) = xt(3)+0.01;
    xt(4) = xt(4)+0.01;
    t.XData = xt; 
    t.YData = yt;
    drawnow limitrate 
end
end
