Hello,
I am currently using the polar.plot function in the plotrix package to graph
data. Unfortunately, it seems that the default for the labels is to have a
background color that is covering the line representing my data, making it
difficult to read. Is there a way to make this label background transparent?
Hi Jimmy,
The easiest way is to change the following lines near the bottom of the
radial.plot function:
boxed.labels(grid.pos-radial.lim[1],ypos,radial.labels,border=FALSE,
cex=par("cex.lab"))
to
text(grid.pos-radial.lim[1],ypos,radial.labels,cex=par("cex.lab"))
If this is a Good Idea, I'll add an option to do one or the other.
Jim
