Simple way to "shrink" the dashes on a line

I want to make the dashes on my lines a lot smaller than they are.

Here is a sample for line of code I used for each line:

plot([2.5 5],[4.71 4.71],'--k')

Here is my current graph:

I want my dashes to be small like this graph has it

I think there might be a way to do, but if my memory is correct, it would not be a simple way, and would involve modifying completely undocumented internal properties inside of completely undocumented internal properties. Using struct() to get access to the private properties might be involved.

I would need to check the details and test (it would not be the first time that properties exist but do nothing when you modify them because you cannot find the right callback to trigger)

Can using linewidth make it happen?

No, line width does not control the ratio of line to gap for dashes, just how thick the line is.
