Hi,
This issue has been signalled before and don’t know how to correct it…
But we will look into it again.
To clearly demonstrate the issue :
#####
size 400,400
xrange -10,10
yrange -10,10
noreset
dashtype 6,6
dashed
arrow -10,4,10,-9,10,blue
arrow -10,4,10,-8,10,blue
arrow -10,4,10,-7,10,blue
arrow -10,4,10,-6,10,blue
arrow -10,4,10,-5,10,blue
arrow -10,4,10,-4,10,blue
arrow -10,4,10,-3,10,blue
arrow -10,4,10,-2,10,blue
arrow -10,4,10,-1,10,blue
arrow -10,4,10,0,10,blue
arrow -10,4,10,1,10,blue
arrow -10,4,10,2,10,blue
arrow -10,4,10,3,10,blue
arrow -10,4,10,4,10,blue
arrow -10,4,10,5,10,blue
arrow -10,4,10,6,10,blue
arrow -10,4,10,7,10,blue
arrow -10,4,10,8,10,blue
arrow -10,4,10,9,10,blue

Using a smaller dashtype (2,2) will make things even worse…
