Hi,
Sometimes I get a graph like the attached one. The data type could
have something to do with it. This graph does not use the color and does
not draw
a line. Earlier I used to convert the factors in the data frame to another
data type and drew the correct graphs.
Any idea why this happens ?
Thanks,
Mohan

Hi Mohan,
If you pass a factor as the "x" value to plot, it assumes that the
values of the factor are nominal or at best ordinal and does not try to
connect them into a metric scale. You can get a "line" with:
plot(as.numeric(data$Var1),data$Freq,ylim=c(0,700),col="green",type="o",
ylab="",xlab="",las=2,lwd=2.5,xaxt="n")
...
but think carefully about whether this means anything sensible.
Jim
