Add text to data points in a circle plot

Hello,

I have a 26x26 matrix called mdist of distances of 26 banks with themselves which i plot like this:

figure;
    x=graph(mdist);
    plot(x,'layout','circle');

The thing is that i need to put the names of each bank in the data points so it looks like the following(mine does not have those names)

You can generally use the text function to insert texts to your plot.

yeah, but i have no idea how to use it in this case, if it was a scatter plot with 2 axis i would just put the values in the x,y of the text function, but in this case as i have a distances matrix, i do not know how to asign each dot its respective name, Thanks!

If you get the handle of GraphPlot

p = plot(G,'layout','circle');

Then you can get the x and y location of each node using

X = p.XData
Y = p.YData

However, If you want to add text at an arbitrary point, then you can make the xtick values visible and then use text() to add the text at the location you want

figure;
ax = axes();
A = randi([1 10], 50);
G = graph(A,'upper');
p = plot(G,'layout','circle');
ax.XAxis.TickValuesMode = 'auto';
ax.YAxis.TickValuesMode = 'auto';

text(0, 0.5, 'myText', 'FontSize', 14, 'Color', 'r')

And then you can again make them invisible using

ax.XAxis.TickValues = []
ax.YAxis.TickValues = []

Clever interpretation!
