Insert text to the image in for loop

9 views (last 30 days)
Hi,
I am trying to insert text to the series of images being generated for each iteration in for loop. For instance, lets say for f = 1:1:200, at f = 1 ieration i need to insert text of t = 0 s likewise t = 0.0002 s, t = 0.0004 s, t = 0.0006s for f = 2, 3, 4 ans so on respectively..
Please help me with this..

for g = 0:0.00002:0.04

end

Instead of recreating graphics object every iteration of your loop, it is often faster to create the object once and then update the properties:
text_handle=text(25,-35,'');
for g = 0:0.00002:0.04
text_handle.String=sprintf('t= %.5f',g);
drawnow % force graphics update
end

Yes.. I have sorted the issue..
I am using as follows, now its better
t = 0.0002 * (i);
text(5,-35,[sprintf('t = %g s', t)],'FontSize',18,'Color','b','Interpreter','latex');
