R help - Mar 2011 - Help with Time Series Plot‏

Dear List,

This is an embarrassing question, but I can seem to make this work…How do I
change the font size on the xlab and on the numbers shown in the x-axis on
the time series plot below. The arguments cex.lab and cex.axis do not seem
to be 'passing' to the plot function.

plot(ts(rnorm(100), start=2004, freq=12),
      ylab="RQI", xlab="My X lab", col="black",
cex.lab=0.1, cex.axis=0.7)
Thanks,
Axel.

Hi:

Try this:
plot(ts(rnorm(100), start = 2004, freq = 12), xaxt = 'n', yaxt =
'n',
      xlab = '', ylab = '')
axis(1, at = c(2004:2012), cex.axis = 0.7)
axis(2, cex.axis = 0.7)
title(xlab = 'My X lab', ylab = 'RQI', cex.lab = 0.1)

The illegible dots in the region where the axis labels would normally be is
the consequence of cex.lab = 0.1 :)

This appears to be a consequence of plotting a time series with plot.ts().
In a basic scatterplot, such as
plot(1:10, 1:10, cex.axis = 0.7, cex.lab = 0.5)

the cex arguments for both axis and lab are respected.

HTH,
Dennis

This seems to be a result of the way plot.ts is coded.
It does seem unnecessarily restrictive to me, but there
may be a good reason and it's easy to work around.

If you want both axes/labels to be scaled the same way,
just do:

  op <- par(cex.axis = 0.7, cex.lab = 0.1)
  plot(tsobject)
  par(op)

For more control over the axes, skip labelling with the
plot call and add the axes/labels with axis() and title():

  plot(tsobject, ann=FALSE, axes=FALSE, frame=TRUE)
  axis(2, cex.axis=0.5)
  axis(1, cex.axis=1.2)
  title(xlab="this is X", cex.lab=0.8)

?axis
?title
