How to read the coordinated from the plot in MATLAB 2018 version?
1 view (last 30 days)
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?

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.
