Hi all,
I am have some difficulty with the legend function.
I need to add a legend to describe the different line types in a plot. The
legend box is small.
It did not include sufficient length of each line type to help distinguish
the differnt line types.
Is there a way to fix this.
Thank you
Hannah
If I understand correctly, you want to have longer
line segments in your legend. I agree that this is
sometimes desirable but, with the current code,
it's not possible - the segment length is hard-coded.
If it matters enough to you, you can easily modify the
code to achieve your aim: search for the following two
lines and in each replace the '2' with a greater value,
say '3'.
First line:
w0 <- w0 + (2 + x.off) * xchar
Second line:
seg.len <- 2
I don't think that this will have any undesirable side
effects, but I haven't given it much thought. I haven't
had any problems with this version of legend().
