Plot command, horizontal line as a marker

Hi,

I am combining a bar plot with a line plot and want to use the '_' as the marker for the line plot. However when I run the command, I get the following error

plot(1:1:4,1:1:4,'k','LineStyle','none','Marker','_')
Error using plot
'_' is not a valid value. Use one of these values: '+' | 'o' | '*' | '.' | 'x' | 'square' | 'diamond' | 'v' | '^' | '>' | '<' | 'pentagram' | 'hexagram' | 'none'.

The Matlab help for the line specfication says that '_' is an option but it somehow does not work.

There's a demo of the '_' marker combined with a bar plot in this community highlight (r2020b or later required).

The '_' (and '|') markers were introduced in R2020b. So to use it, you will need to upgrade to the latest release. (The online documentatiion is for R2020b.)
