I want to create axis (X,Y) with dateticks.
I want to plot the data with axis(xlim and dateticks - hh:mm:ss.SSS) but I am getting an error
Edited
ans =
101×1 duration array

Check out your values of xstart xend. Then look at the error message and ask yourself what requirements you're not fulfilling. There are 3 requirements according to the error message.
To address the 1st point, size([xstart xend]); is that 1x2?
To address the 2nd point, class(xstart) and class(xend); is it numeric?
To address the 3rd point, xend>xstart; is it true?

- Sorry, xstart and xend should each be 1x1. The [xstart, xend] should be 1x2 which looks OK in your data above.
- If your x-data are duration, your x-limits need to be durations, too. That's directly from the documentation. "You can specify the limits as numeric, categorical, datetime, or duration values. However, the type of values that you specify must match the type of values along the x-axis."
- The 2nd value of your x-axis limit must be greater than your first value. That makes sense because you're setting the [lower, upper] bounds of the x-axis.
So you need to fix #2 and #3. My answer has a function demo.

I see your data are durations along the x axis. To set the axis limits,
- Use xlim() where the first input is your axis handle and your 2nd input is a [1 x 2] vector of durations
- The 2nd value of your x limit must be larger than the first value
Here's a demo
% Create data and plot it on UIAxes
h = duration([9 17 54;12 32 3]);
app.uiax = uiaxes();
plot(app.uiax,h,[0,1], '-o')
% Create the [start,end] x-limits
xstart = duration(9,0,0);
xend = duration(13,0,0);
% Set the x limits: xend must be larger than xstart
xlim(app.uiax,[xstart, xend])
If your are plotting this : [c{range,1},range]
then you minimum and maximum durations would be
xstart = min([c{range,1},range]);
xend = max([c{range,1},range]);
