Thread Subject: How to display values on a plot

hi,

is there a way to display a value instead of circles for
points on an x-y plot?

as an simple example, suppose my data points are numbered:

indic x y
1 1.2 0.66
2 2.7 0.58
3 3.6 0.44
...

I want each the value in indic to show up in the plot
instead of default circles so that i know where each pair
of values are on the plot directly.

any way to do this?

Did you try 'text' funtion?

text(x,y,num2str(indic),'HorizontalAlignment','center')

then set scaling for the x- and y-axes by axis function

axis([min(x) max(x) min(y) max(y)]

Or combine plot and text functions

plot(x,y,num2str(indic),'.')
text(x,y,num2str(indic),'HorizontalAlignment','center')
