How do I write a line for adding a text to my plot?

Hi,

I am trying to add a text to my plot. I tried adding the following line to the code: text('k=28');

I also tried: txt= 'k=28';

Both lines didn't add the text , I am atatching my existing code below. This code is part of the function file.

fig = figure('position', utilities.centerFigPos(1500, 1200));

set(fig, 'Color', 'white', 'defaultLineLineWidth', 2, 'defaultAxesFontSize', 24);

ax = axes(fig);

scatter(ax,X,Y,'o');

line(ax, xFit, yFit);

ax.Title.String = 'Data';

ax.XScale = 'linear';

ax.YScale = 'log';

ax.XLim = [0,1];

ax.YLim = [yMin,1];

ax.YDir = 'reverse';

The text function requires x and y values (or x, y, z values).

Alternatively, use the title function if you want a title for your plot (I see you already found this by setting the Title.String property)

scatter(randn(100,1),randn(100,1))
text(2,2,"k=28")
title("My Plot")
