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

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.
