R help - Nov 2009 - Overlapping x - axis lables

Dear R helpers

Suppose I am plotting a simple scatter plot where no of paired observations
(x,y) are say 100.


month          length
1                   10
2                   12
3                   17
4                   21
5                   13
..........................
..........................
..........................

100              16



when i run the command

plot(month, length)

the required plot is generated. But the problem is that on  the X - axis, month
values are also printed and it becomes difficult to read the month values on the
graph.
 
(Actually I am working on a stacked graph where I am facing this problem.)

So, how to display only few month values (say 1, 5, 10 and so on) without
affecting the original graph i.e. the graph should display all the data 100
points but on x - axix only few month values should be displayed in order to
improve the readability.

Thanking in advance

Julia

Hi Julia,
Try this:

plot(month,length,xaxt="n")
axis(1,at=seq(1,100,by=5),labels=seq(1,100,by=5))

If the labels are still crowded, increase the "by" value.

Dear Sir,

Thanks again for your help. Sir, actually I am working on a data containing 84
months and the corresponding savings (core) balances and non-core balances and I
am plotting a stacked bar.

The original code I am using is as follows

x = read.csv('core-noncore.csv')

x2 <- data.frame(rep(x$month, 2), stack(x, select = -month))   
names(x2) <- c('month', 'Count', 'Type')
library(lattice)
barchart(Count ~ month, groups = Type, data =x2, horizontal = FALSE, stack
=TRUE, auto.key = list(columns = 2))       # stacked  vertical bar chart

However, when I try to apply the code given by you, its showing the error 
"plot.new has not been called yet"

Sir, is it that the command works only with plot command and not with barchart.

Warm regards

Julia

Hi Julia:

Two things:
  (i) use axes = FALSE in your initial call to plot();
  (ii) use axis(1, at = 10 * (0:10))   if you want it by tens, for example
                axis(2)      # use default
                box()         # if you want a box around the plot.

?axis is your friend here.

HTH,
Dennis
