ggplot2 line graph - scaled?

[Lighton Phiri]

I am having trouble telling ggplot2 to graph this dataset [1]. The
resulting plot [2] is nothing compared to what I get [3] when I use R
base graphics.

I suspect ggplot2 is automatically scaling the data; how do I go about
getting the results I get when I use base graphics?

ggplot2 code

Accidentally hit the send button before I finished writing... the
ggplot2 code I used is below

ggplot(data=info, aes(x=Workload, y=value, color=variable)) +
geom_line(aes(group=variable)) + geom_point()

Your base graphic seems to use a log scale for the x axis.

HTH,

Is there a way around getting ggplot2 do what base graphics are doing?
Incidentally, using LibreOffice Impress results in a plot similar to
that of base graphics...

Here's the easiest way....

ggplot(data=tst.melt, aes(x=as.factor(Workload), y=value, color=variable)) +
+ geom_line(aes(group=variable)) + geom_point()

Neat! Exactly what I wanted --thank you very much Adam. I am curious as to why ggplot2 behaves like it did by default though...

ggplot2 is not doing anything unusual. You mapped a numeric vector on
the x axis, and did not change the default x-axis scale, so you got a
plot where the x-axis intervals map to the numeric difference between
each successive x-axis value. If that's not what you want you can
change it--either by telling ggplot to ignore the numeric values of
Workload (as Adam suggested) or by using a log scale (as baptiste
suggested)--but it is the reasonable default.

Best,

That makes sense, thank you for this.
