Plot multiple time ranges on a single line?

Hello,

I have a Nx2 timetable of start (column 1) and end (column 2) times, read from a csv file. Each of these time ranges describe a session of data collection for location 'A' An example is this:

A =

'04/19/0022 14:37' '04/19/0022 22:49'

'05/03/0022 14:47' '05/03/0022 23:01'

'05/17/0022 16:58' '05/17/0022 23:02'

'05/31/0022 15:02' '05/31/0022 23:07'

'06/14/0022 14:33' '06/14/0022 23:03'

'10/26/0022 23:28' '10/28/0022 14:14'

'11/02/0022 23:58' '11/04/0022 00:18'

'11/14/0022 17:07' '11/16/0022 01:11'

How might I best plot this data in a time series so each collection session shows as a bar/whisker line on one horizontial axis within the plot?

Additionally, if I had another location and associated variable, 'B', how would I add this second horizontial line with sessions into the graph?

I've drawn an example here (the times don't match to the above data):

I have considered Gantt charts but this seems to be built more specifically towards different mixing of 'A' and 'B' between the horizontial planes.

Thank you.

I have created a code based on the values you wrote down and the picture attached.

You can edit this code by adding the data you need.

%% data
A = {
'04/19/2022 14:37'	'04/19/2022 22:49'
'05/03/2022 14:47'	'05/03/2022 23:01'
'05/17/2022 16:58'	'05/17/2022 23:02'
'05/31/2022 15:02'	'05/31/2022 23:07'
'06/14/2022 14:33' '06/14/2022 23:03'
'10/26/2022 23:28'	'10/28/2022 14:14'
'11/02/2022 23:58'	'11/04/2022 00:18'
'11/14/2022 17:07'	'11/16/2022 01:11'};

for ii = 1:height(A)
    dnum(ii,1) = datenum(A{ii,1});
    dnum(ii,2) = datenum(A{ii,2});
end


%% figure
figure()
for ii = 1:height(A)
    % set
    hold on;
    x = [dnum(ii,1) dnum(ii,2)];
    y = [6 6];
    % plot
    plot(x,y,'k','LineWidth',5)
    % deco
    xlim([dnum(1,1) dnum(end,2)])
    datetick('x','mm-dd','keeplimits','keeplimits')
    xlabel('mm-dd (2022)')
    
    ylim([0 10])
    yticks([4 6])
    yticklabels({'B','A'})
end

Thank you! That helped me move in the right direction and your code was a great sample.
