I am having an issue where I am plotting data using datetime (converting from excel) and it is giving me the date stamp of the current day on the plot. I need to specify the date I want and stamp it onto the plots without interfering with the data. How can I do this?

So, you are reading a date and time from Excel into a datetime variable, but the datetime variable is for the current day not the day in the Excel file. It might help if you provide the data and your code.

Hi Scott. That is exactly right except the data conversion only has the time, not the date. I am unable to provide the data due to confidentiality reasons, but here is a graph that has the date. This is by no means the data I am trying to plot but it is a plot of the time from the datetime conversion with the date at the top. That is the date I would like to change.

The only way I can devise to delete the date is to create new y-tick labels and use them instead —
F = openfig('untitled.fig');
Ax = gca; % Axis Handle
yt = Ax.YTick; % Y-Tick Values
ythm = compose("%02d:%02d", [hour(yt); minute(yt)].') % Create New Ones
Ax.YTickLabel = ythm; % Use Them For The New Y-Ticks
text(min(xlim), max(ylim), 'Your Date Here', 'Vert','bottom', 'Horiz','left')
The new plot —

Added text call to insert ‘Your Date Here’ date information.

plot(1:10, 1:10)
title("This plot was created at " + string(datetime('now')))
