% Plot the waveform.
subplot(rows, rows, k);
tDouble = (1 : length(y)) / fs; % Get time axis as a double. Convert number of elements into actual seconds (still a double though).
tDouble = tDouble / 60; % Convert to minutes (still a double though).
tMin = datetime(0,0,0) + minutes(tDouble); % Convert variable class from "double" to "duration".
plot(tMin, y(:, 1)); % Display waveform.
% Make the plot fancy.
% Make the time axis show up in mm:ss format
ax = gca;
% xt = datetime(0,0,0) + minutes(0 : 0.5 : max(tDouble)); % Tick marks every 30 seconds.
xt = datetime(0,0,0) + minutes(0 : 1 : max(tDouble)); % Tick marks every 1 minute.

% Have it end on the last element, not necessarily on minute boundaries.
xlim([datetime(0,0,0), tMin(end)]);
ylim([-1, 1]);
drawnow; % Force display to update immediately.
The above shown is my code when i run it shows error like this

Error using uicontrol
There is no verticalalignment property on the UIControl class.

There is no VerticalAlignment property for uicontrol objects (neither in R2018a or R2021b). A center alignment is the default. For other object with such a property this is generally called middle.
There is a property HorizontalAlignment. The default value is center, so you don't need to specify it.

Why did you unaccept this answer? Why is it now incorrect?
