This command:
FL=animatedline('LineWidth',5)
Compare to:
FL=animatedline('LineWidth',25)
Gives FL 25 size both x and y direction.
Meaning it never shows smaller than 25 y direction, and visually never 'goes away'.
Why?

Hi Steinar ,
I think you are missing the coordinate the point for which you want to join by the line. The commands you have provided gives only the axes and line width of the axes does not change with parameter. For example, you may try the following for illustration:
>> FL=animatedline([1 2],[15 16],'LineWidth',5,'LineStyle','-')
as compared to
>>FL=animatedline([1 2],[15 16],'LineWidth',25,'LineStyle','--')
You may consider contacting MathWorks Technical Support of you region if you have more assistance.

Sorry, here are som more info.:
forcevector=animatedline('LineWidth',5,'color','b');
clearpoints(forcevector);
FrontLine=animatedline('LineWidth',25,'color','blue');
clearpoints(FrontLine);
BackLine=animatedline( 'LineWidth',25,'color','red');
clearpoints(BackLine);
for i=1 : 20 : length(Fres) addpoints(forcevector,[ResX Fres(i,1)+ResX],[ResY Fres(i,2)+ResY]) drawnow
addpoints(FrontLine,[FrontX FrontX],[FrontY Front2(i)+FrontY])
drawnow
addpoints(BackLine,[BackX BackX],[BackY Back2(i)+BackY])
drawnow
M = getframe(gca);
writeVideo(mov,M);
clearpoints(forcevector);
clearpoints(FrontLine);
clearpoints(BackLine);
end
But the line's are squared in size, not only width...
