Hi,

I was trying to draw scatter plots with smooth lines using ggplot2. When I transpose X/Y axis (data), the smooth line didn't.

I thought smooth lines were to show the trend of data. Am I misunderstanding?

When I changed below

```
p <- qplot(
log2(countsNormalized[,1]+1),
log2(countsNormalized[,4]+1),
xlab="A",
ylab="B",
alpha=0.9)
p +
geom_smooth(method="lm",se=F) +
geom_abline(intercept = 0,linetype="dotted") +
geom_point(size=3) +
stat_smooth_func(geom="text",method="lm",hjust=0,parse=TRUE)
```

to next

```
p <- qplot(
log2(countsNormalized[,4]+1),
log2(countsNormalized[,1]+1),
xlab="A",
ylab="B",
alpha=0.9)
p +
geom_smooth(method="lm",se=F) +
geom_abline(intercept = 0,linetype="dotted") +
geom_point(size=3) +
stat_smooth_func(geom="text",method="lm",hjust=0,parse=TRUE)
```

the smooth line stayed the same.

Any ideas would be helpful. Thanks.

By the way, how can I put picture here?
