Goal: adjust overlapping 'text' items in plot so they are legible
I have located 'space' as one possible technique for decluttering
text positions on a plot. I would rather not jitter the plot point, just
the text nearby.
Are there other techniques or functions available that declutters a plot
using 'text'?
Perhaps an arrow or a line to the plot mark could be used to
lead to the text item.
The following will demonstrate my concern. If you do not see overlap
use a larger value for plot density. The plot I am attempting with the
real data has a density of 64 providing space adjacent to the point.
In the real data there are few clusters that have tighter spacing
than produced in the example below. A plotdensity value of 150 or so
will give a better visualization of the issue.
Thanks.
# EXAMPLE VIEW
plotdensity<-150
x1<-rnorm(plotdensity)
y1<-rnorm(plotdensity)
plot(x1,y1)
textLabels <- as.character(1:plotdensity)
text(x1,y1,textLabels,pos=1)
=I have also reviewed sunflowerplot.
