Hi,
I'm building two graphics just changing the scale to show the graphic
illusion.
The first graph would be 'correct'.
atend = c(410,430,450,408,408,405)
names(atend) = c('Janeiro', 'Fevereiro', 'Março', 'Abril', 'Maio', 'Junho')
barplot(atend, las=1, xlab='Meses', ylab='Número de atendimentos',
col='LightYellow', yaxt='n', space=0.6)
axis(2, at=seq(0,450, by=50), las=1)
abline(h=0, col='black', lwd=1)
How should I do to get the second graph in the range 400 and Y in the
columns with values below 400 do not appear on the chart?
If I understand correctly, you should be able to just subtract 400
from atend and adjust the axis() command:
barplot(atend-400, las=1, xlab='Meses', ylab='Número de atendimentos',
col='LightYellow', yaxt='n', space=0.6)
axis(2, at=seq(0,50, by=10), lab=seq(400,450, by=10), las=1)

atend = c(410,430,450,408,408,405)
names(atend) = c('Janeiro', 'Fevereiro', 'Março', 'Abril', 'Maio', 'Junho')
barplot(atend, las=1, xlab='Meses', ylab='Número de atendimentos',
col='LightYellow',ylim=c(400,450), yaxt='n', space=0.6)
axis(2, at=seq(400,450, by=10), las=1)
abline(h=400, col='black', lwd=1)
Thanks,
