Hello all, this is the first time i write here. I made this plotting and basically is the same plot but in different point of view. I would like to start the "two cycle for" simultaneously, or at least plotting the result simultaneously. I saw there is another question like this but i can't understand the answer.

%%defining variables
np=length(xT);
x=flip(xT);
y=yT;
z=zT;
%%a kind of option menú
on=1;
off=0;
enable_plot_dot_3d=off;
enable_plot_line_3d=on;
enable_plot_vertical=on;
subplot (1,2,1)
%%starting plotting first point
plot3(x(1),y(1),z(1))
view([180 90])              %set azimuth and elevation of plot
xlim([min(x) max(x)]);
ylim([min(y) max(y)]);
zlim([min(z) max(z)]);
grid
hold on
%%starting add the others point according of menú
for i=2:np-1
 %  line (i make a mistake with variable name)
 if(enable_plot_dot_3d) %un po inutile per me
    plot3(x(i:i+1),y(i:i+1),z(i:i+1),'-r','linewidth',2)
 end
 %  dots
 if(enable_plot_line_3d)
    plot3(x(i+1),y(i+1),z(i+1),'o','markerfacecolor','r')
 end
 % height marker
 if(enable_plot_vertical)
    plot3([x(i+1) x(i+1)],[y(i+1) y(i+1)],[0 z(i+1)],'b')
 end
% plot speedy
 pause(sec+0.05)
end
subplot (1,2,2)
%%starting plotting first point
plot3(x(1),y(1),z(1))
view([180 0])              %set azimuth and elevation of plot
xlim([min(x) max(x)]);
ylim([min(y) max(y)]);
zlim([min(z) max(z)]);
grid
hold on
%%starting add the others point according of menú
for i=2:np-1
 %  line (i make a mistake with variable name)
 if(enable_plot_dot_3d) %un po inutile per me
    plot3(x(i:i+1),y(i:i+1),z(i:i+1),'-r','linewidth',2)
 end
 %  dots
 if(enable_plot_line_3d)
    plot3(x(i+1),y(i+1),z(i+1),'o','markerfacecolor','r')
 end
 % height marker
 if(enable_plot_vertical)
    plot3([x(i+1) x(i+1)],[y(i+1) y(i+1)],[0 z(i+1)],'b')
 end
% plot speedy
 pause(sec+0.05)
end
%%clear temporary variables
clear enable_plot_vertical enable_plot_dot_3d...
  enable_plot_line_3d i np on off

thanks a lot Mike for the answer i made it by using

 set(h,'visible','off')
 set(h,'visible','on');

where 'h' is the plot variable

%defining variables
np=length(xT);
x=flip(xT);
y=yT;
z=zT;
h=figure();
set(h,'visible','off');                 %ths prevent figure to show data
subplot (1,2,1)
% starting plotting first point plot1
plot3(x(1),y(1),z(1))
xlim([min(x) max(x)]);
ylim([min(y) max(y)]);
zlim([min(z) max(z)]);
grid
view([180 90]) 
hold on
%starting plotting first point plot2
subplot (1,2,2)
plot3(x(1),y(1),z(1))
xlim([min(x) max(x)]);
ylim([min(y) max(y)]);
zlim([min(z) max(z)]);
grid
view([180 0])
hold on
%starting add the others point
for i=2:np-1
  subplot (1,2,1)
  plot3(x(i:i+1),y(i:i+1),z(i:i+1),'-r','linewidth',2)
  plot3(x(i+1),y(i+1),z(i+1),'o','markerfacecolor','r')
  plot3([x(i+1) x(i+1)],[y(i+1) y(i+1)],[0 z(i+1)],'b')
    subplot (1,2,2)
    plot3(x(i:i+1),y(i:i+1),z(i:i+1),'-r','linewidth',2)
    plot3(x(i+1),y(i+1),z(i+1),'o','markerfacecolor','r')
    plot3([x(i+1) x(i+1)],[y(i+1) y(i+1)],[0 z(i+1)],'b')
    pause(sec+0.05)                     %just a pause to see data better
    set(h,'visible','on')               %this show all the data again
end
%%clear temporary variables
clear enable_plot_vertical enable_plot_dot_3d...
  enable_plot_line_3d i np on off

Guiseppe, the idea is to accept the answer of Mike, not your own comment to the answer.

Basically you just want one loop with both plotting commands in it. The tricky part of that is that you're currently depending on GCA when you call plot3. If you want to combine them into a single loop, you're probably going to need to be explicit about which axes each plot goes in. That would look something like this:

%%Create 1st axes
a1 = subplot (1,2,1)
%%starting plotting first point
plot3(x(1),y(1),z(1))
view([180 90])              %set azimuth and elevation of plot
xlim([min(x) max(x)]);
ylim([min(y) max(y)]);
zlim([min(z) max(z)]);
grid
hold on
%%Create 2nd axes
a2 = subplot (1,2,2)
%%starting plotting first point
plot3(x(1),y(1),z(1))
view([180 0])              %set azimuth and elevation of plot
xlim([min(x) max(x)]);
ylim([min(y) max(y)]);
zlim([min(z) max(z)]);
grid
hold on
%%starting add the others point according of menú
for i=2:np-1
 % update 1st axes
 % line
 if(enable_plot_dot_3d) %un po inutile per me
    plot3(a1,x(i:i+1),y(i:i+1),z(i:i+1),'-r','linewidth',2)
 end
 %  dots
 if(enable_plot_line_3d)
    plot3(a1,x(i+1),y(i+1),z(i+1),'o','markerfacecolor','r')
 end
 % height marker
 if(enable_plot_vertical)
    plot3(a1,[x(i+1) x(i+1)],[y(i+1) y(i+1)],[0 z(i+1)],'b')
 end
   % update 2nd axes
   %  line
   if(enable_plot_dot_3d) %un po inutile per me
      plot3(a2,x(i:i+1),y(i:i+1),z(i:i+1),'-r','linewidth',2)
   end
   %  dots
   if(enable_plot_line_3d)
      plot3(a2,x(i+1),y(i+1),z(i+1),'o','markerfacecolor','r')
   end
   % height marker
   if(enable_plot_vertical)
      plot3(a2,[x(i+1) x(i+1)],[y(i+1) y(i+1)],[0 z(i+1)],'b')
   end
  % plot speedy
   pause(sec+0.05)
  end

The important bit here is saving the return values from the 2 calls to subplot (a1 and a2), and then using those as the first arguments in the calls to plot3. That way you can be managing multiple plots at the same time in your loop.

Does that make sense?
