write indexes in a plot

23 次查看(过去 30 天)
Dear
I have a matrix P with n rows and two columns, each of the column store the x and y position of a particle.
Represent the particle postions is easy (plot(P(:,1),P:,2)), I would like to write the index of each particle just beside each point
How can I do it?
Many thanks!!

Hi,
Example code taken from above answer:
x = 1:10; y = 1:10; scatter(x,y);
a = [1:10]'; b = num2str(a); c = cellstr(b);
dx = 0.1; dy = 0.1; % displacement so the text does not overlay the data points
text(x+dx, y+dy, c);
This should resolve your problem.

yes, this is what I am looking for
But a final question, Is there any way to control the size of the numerical labels of each point?

You can specify fontsize property as follow:
text(x+dx, y+dy, c,'FontSize',k);
with k as scalar value equal to your desired fontsize.
