Is there a way we can change what we see currently when clicking on a particular point in the plot?

When I click on a point in the graph I see X 1 and Y 0.1335 but I am interested in showing only A = 0.1335 instead and likewise if it is a B point then the same

If you are using datacursormode then supply a custom update function that returns a cell array of character vectors, one cell for each output line.
Otherwise: particular kinds of plots called "charts" support a newer mechanism that allows a different method of customization; see https://www.mathworks.com/help/matlab/creating_plots/create-custom-data-tips.html

I tested with
h(1) = plot(rand(1,20), 'DisplayName', 'A');
hold on
h(2) = plot(rand(1,20), 'DisplayName', 'B');
hold off
row1 = dataTipTextRow('A' + " = ", 'YData');
row2 = dataTipTextRow('B' + " = ", 'YData');
h(1).DataTipTemplate.DataTipRows = row1;
h(2).DataTipTemplate.DataTipRows = row2;
legend(h);
and then I used the axis toolbare to turn on datatips for the axes. Everything looked fine, with the datatip moving to the closest point to where I clicked, and using the proper "A = " or "B = " before the value.
