Time-variying Map with Slider

Hello. I have a dataset that changes over time. I am using this dataset to make a world map. What I want to do is instant change of the map created using a slider. After creating my data as below, I want to exchange this data with the dates they represent on the slider.But in the meantime, I couldn't figure out how to handle the dates in the slider bar. If I get the date value from the Slider bar, it will be very easy to associate it with the data of that date. Will you help me with this problem?

Place these commands in callback after loading the data_struct variable

            % Convert structural array, data_struct, into a table
            t = struct2table(data_struct);
            % Read dates from table heading
            dates = t.Properties.VariableNames;
            % Convert to datetime
            dates = datetime(dates,"Format","MMMMuuuu");
            % Change datetime format
            dates = datetime(dates,"Format","MMM-uuuu");

            app.Slider.Limits = [1, length(dates)];
%             app.Slider.MajorTicks = 1:1:length(dates);
%             app.Slider.MajorTickLabels = string(dates);
            app.Slider.MajorTicks = 1:5:length(dates); % you can adjust the increment to best suit your data
            app.Slider.MajorTickLabels = string(dates(1:5:end));
            app.Slider.MinorTicks = [];           
            imshow(data_struct.(t.Properties.VariableNames{app.Slider.Value}),"Parent",app.UIAxes)

For slider callback:

            imshow(data_struct.(t.Properties.VariableNames{app.Slider.Value}),"Parent",app.UIAxes)
