Hi every body
I want to draw a bisection Y-axis plot which scaled from 0 to 100. At first section (1 to 30) it would be ranged by 2 (2,4,6,...,30)and after that it would be ranged by 10 (30,40,50,...,100). how can I draw this plot?
Thank you
Hello Mohsen,
If you are using ggplot2 you can use the following trick:
[YOUR GGPLOT2 PLOT OBJECT] + scale_y_continuous(breaks=c(seq(2,30,2), seq(40, 100, 10)))
Regards

If the axis should show one variable, I would NOT suggest to cut the axis. Instead, better use a logarithmic scale if your aim is to show small and large values on the same axis.
However, if you still want to do this, you need to invest some work to convert between coordinate systems (scales). This is all simple arthmetic. Here is an example script that will produce a scatterplot with a cut y-axis:
# x: x-values
# y: y-values
# s1, s2: scales: vectors with tickmark positions. s1 is the "lower" scale, s2 is the "upper" scale. # ratio: ratio of the length of s2 relative to s1. A ratio of 1 means that both scales will be represented with the same length
# cutw: witdth of the cutting region between the scales relative to the total height of the plotting region
# bty: box-type, by default set to "n" (no surrounding box)
# ...: other arguments passed to plot() and to points()
cutplot 0 & cutw < 0.5)
stopifnot (length(s1)>1 & length(s2)>1)
stopifnot (identical(c(s1,s2), sort(c(s1,s2))))
# get helpers for conversion from scales s1 and s2 to y-scale

Hello
Thank you all dear
All of your suggestions and procedures are applicable and worthy. Thank you again.

Dear Waldemar Koczkodaj,
Thank you, i saw gnumeric web site but there is no release for windows. I am one of the Windows users.
