Hi Neelakandan,

You can achieve saving the data tip values of a plot to some variables in the App Designer by creating data tips programmatically using the 'datatip' function on a plotted object and then accessing the data tip's properties.

For more information on 'datatip' function you can refer following:

https://www.mathworks.com/help/matlab/ref/matlab.graphics.datatip.datatip.html

Below are the steps, you can follow:

1. First, plot your data within the App Designer, something like below:

% Assuming ax is the handle to your UIAxes
plot(app.UIAxes, xData, yData);

2. After plotting, you can create a data tip on a specific data point by specifying the target plot and the data point index or coordinates.

% Create a data tip on the first data point of the plotted line
% Assume the plotted line object is stored in 'plotted'
plotted = plot(app.UIAxes, xData, yData);

% Create a data tip at the first data point
dt = datatip(plottedLine, 'DataIndex', 1);

3. Once you have created a data tip, you can extract its values or other required properties as per your use case and then store these values in your app's properties or use them directly for further calculations or display within the app.
