R devel - Sep 2004 - Wishlist: axis() and line widths (PR#7223)

Full_Name: Tom Short
Version: 1.9.1
OS: Win2000 & Debian
Submission from: (NULL) (64.65.255.41)


WISHLIST:

axis() has a default parameter of "lwd = 1". I want skinnier lines as
the
default. If I change the default lty, it doesn't change what axis uses.

The following code produces a graph with a box around it, but the axis lines are
twice as thick as the box around the plot, so it looks funny. I can manually add
axes and explicitly set line widths, but that's a pain. The box() function
does
not set lty, so it uses the default par()$lwd.
> par(lty = 0.5)
> plot(c(1,2,3)) 
RECOMMENDATION: In axis(), change the default for "lwd" from 1 to
par()$lwd.

Looks like you are confusing lty and lwd???

Anyway, both lty and lwd work fine:

  plot(1:10)
  axis(1, lty=2, col="red")
  axis(2, lwd=2)

For sure you mean

par(lwd=0.5)
plot(1:3)

But that won't work on arbitrary devices (AFAIR), because 0.5 is smaller 
than 1 - and it's hard to draw things that are smaller than one point.

No. If you want to change line widths of stuff within your plot, you 
don't want to change it for your axes as well.
