I am plotting a circle based on list of x and y co-ordinates in a .txt as input.How can I view the points on the circle once it is plotted?

Suchita - you could can enable the data cursor mode on the figure. For example, suppose we plot the sine wave as follows
close all;
x=-2*pi:0.0001:2*pi;
y=sin(x);
h=figure;
plot(x,y)
You can then enable the data cursor mode as
datacursormode(h,'on');
Now when the cursor moves across the figure, it has the shape of the plus symbol (cross-hairs). Clicking near a point on the sine curve snaps the cross-hairs to that point and text box appears displaying the x and y coordinate.
To turn the data cursor mode off, just type
datacursormode(h,'off');

Do you know how to go to the next point on the plot without clicking on it, just starting from the initial point and using a key ? The arrow keys don't make it unfortunately.
