I have created GUI, in that I wanted add a feature that it should read the coordinates from the graph in MATLAB 2018 version. In this version there is no 'Current point' , and 'datacursor mode' is also not working for the app.UIFigure. Is there any alternative way to read the coordinates from the graph?

What errors are you observing in the 2021 version?

It would be better if you thoroughly describe the functionality you had/have/and wish to have. First you talked about a graph, now you talk about showing images. Describe, in detail.

If you make a simple graph:
ph = plot(X,Y);
Then you can always extract the data-points from the plot-handle ph:
xGraph = get(ph,'XData');
yGraph = get(ph,'YData');
From there you can display them any whichever way you see fit. However, a lot more can be presented in a graph, and this makes your question impossible to answer in a way that covers all graphs in general. Hopefully this is useful to your case.
