How to use set(h, 'XData', x...) when x is datetime or duration?

Hello Guys,

I have large size csv-table with timestamp and data, i want to plot it in a better way with function set(h, 'XData', ...). After reading this page How should I update the data of a plot in Matlab? - Stack Overflow i have wrote the following approach:

tic
t = readtable('data_Mat1_2022_02_11_23_31.csv');
ax = axes;
h = plot(nan, nan);
x = t.Time;
y = t.Data;
set(h, 'YDataSource', 'y');
set(h, 'XDataSource', 'x')
n = height(t);


for i = 1:n
    set(h, 'XData', x, 'YData', y);
end
toc

But when i run my code there will be the error:

Error using matlab.graphics.chart.primitive.Line/set
Value must be a vector of numeric type.

Error in plotTime (line 13)
set(h, 'XData', x, 'YData', y);

So i want to konw how to correct my code or there is another efficient way to update plot of a table, thanks for all your helps!

I do a little change to my code and it works

tic
t = readtable('data_Mat1_2022_02_11_23_31.csv');
ax = uiaxes;

Error using uiaxes (line 47)
This functionality is not available on remote platforms.

x = t.Time;
y = t.Data;
toc
tic
%plot(t.Time, t.Data)
h = plot(ax, x(1), y(1));

set(h, 'YDataSource', 'y');
set(h, 'XDataSource', 'x')
n = height(t);
set(h, 'XData', x, 'YData', y);
toc

Output

Elapsed time is 0.208487 seconds.
Elapsed time is 0.006211 seconds.

Maybe the bottleneck is the time of reading table
