Plot animation with Struct. Variables

4 views (last 30 days)
I was trying to turn this sequence for a single plot into a movie. Beam.x and Beam.y is a 100 spot vector. My original code is:
plot(x,y,'--r','LineWidth',3); % This is the original position of the Beam
hold on % Holds only the axes values
line(Beam.x,Beam.y,'color','b','linewidth',2); % The New position of Beam
xlabel('Beam Length (in.)','Color','g');
ylabel(bstr,'Color','g');
ylim([-(Beam.y(10)) max(Beam.y)]);
legend('Without Deflection','With Deflection');
title(astr,'Color','y','fontweight','b');
set(S.ax,'YDir','reverse');
set(S.ax,'XGrid','on');
set(S.ax,'YGrid','on');
hold off
Anytime I try to turn it into a movie or anything of the sort I get the error:
The following error occurred converting from struct to double:
Error using double
Conversion to double from struct is not possible.
OR:
Error using capturescreen
Figure destroyed during getframe
Error in getframe (line 103)
x=builtin('capturescreen', varargin{:});
Any ideas?

Which line of code shows the problem about converting struct to double? How are you trying to turn it into a movie?

% Data
clear; close all;
M = zeros(1,100);
x = linspace(1,100);
y = linspace(50,100);
% figre
figure(1);
set(gcf,'Renderer','OpenGL');
h = plot(x(1),y(1),'-r','linewidth',6);
set(h,'EraseMode','normal');
% Animation
j = 1;
for j = 1:100
set(h,'XData',x(j))
set(h,'YData',y(j))
plot(h)
M(j) = getframe;
end
movie(M,2)
The Code above is what I have been messing with to figure the animation thing and it keeps on returning the first error.
