 Subject: text in image From: Betty Vag Date: 10 Oct, 2010 12:20:04 Message: 4 of 6 how can I text the value of i ??? my command is like this: for i=1 : 10 text(10+i*50, 681, '.',...     'Color', [1 1 1], 'FontSize', 12); end i want to text the value of i next to the spot. what should I do?
 Subject: text in image From: Image Analyst Date: 10 Oct, 2010 13:41:03 Message: 5 of 6 You mean like this: for k=1 : 10     string = ['.' num2str(k)]; text(10+k*50, 681, string,...     'Color', [1 1 1], 'FontSize', 12); end Note I changed i to k since it's not a good idea to use i (the imaginary constant) as a loop iterator.
