Details:

When I make a scatter plot by using "|" as a symbol,as shown in attached
figure, I find no way to deal with it.
This problem has been solved in matlab 20b version as mentioned in
https://de.mathworks.com/help/releases/R2020b/matlab/release-notes.html?category=graphics&rntext=marker&startrelease=R2015b&endrelease=R2020b&groupby=release&sortby=descending.

There is a way to achieve this function by using text() as shown in followed
codes:

x = 1:50;
y = rand(size(x));

figure
plot(x, y, '.', 'Color','none')
axis([0  50    0  1])
text(x, y, '|', 'VerticalAlignment','middle', 'HorizontalAlignment','center',
'Color','r')

However, if the data is large, this will take long time to run the program.
Can this function be added in the Marker type list?
