legend order in ggplot2
Hi,
I'd like to graph three lines on ggplot2 and I intend the lines to be
"solid", "dashed", and "dotted". The legend names are "name_b", "name_a",
"name_c". I'd like to legend to present in the order: the "name_b" at the
top, and "name_c" at the bottom.
As a consequence, the legend is indeed in the order:

legend order in ggplot2
Hi
Your approach seems to me rather complicated. I would reshape data before plotting and maybe also change order of levels in resulting variable factor
library(reshape2)
dfm<-melt(df)
dfm$variable<-factor(dfm$variable, levels=levels(dfm$variable)[c(2,1,3,4)])
p2<-ggplot(dfm, aes(x=rep(1:2,4), y=value))
p2+geom_line(aes(linetype=variable))+

legend order in ggplot2
Hi,
I ran your code, but the results were not as expected. After I ran the
code by "source", it return
No id variables; using all as measure variables
> p2
and no line or legend is on the graph (as attached)
Am I doing anything wrong?

Change the legend order by order function
Hi,
I'd like to graph three lines on ggplot2 and I intend the lines to be
"solid", "dashed", and "dotted". The legend names are "name_b", "name_c",
"name_a". I'd like to legend to present in the order: the "name_b" at the
top, and "name_a" at the bottom.
Could it be done by order function or its inverse?

ggplot2: mixing colour and linetype in geom_line
Hi all,
I try to represent a multiple curve graphic where the x-axis is the
temperature and the different y-axes are the different X (X22,X43,X44...)
some X corresponds to the same molecule (22 and 44 are for CO2 for instance)
so I use the same colour for them.
I wanna mix the linetype with the colour to be able to visually see the
difference between X43 and X45
The best I have done up to now

Change the legend order by order function
There are two key concepts you seem to be unaware of regarding ggplot: 1) you really need to put your data in long format to work with multiple curves, and 2) the column containing the names of the curves should be a factor with levels in the order you wish them to be presented in the legend (bottom to top). I am not in a position at the moment to give you a full reprex, but Google can probably

nesting scale_manual caracteristics in ggplot
Hi there,
I am having a little problem with combining three scale_manual commands in a
facet plot. I am not able to combine the three different characteristics,
instead ending up with three different descriptions next to the graph for
the same geom. I would like to see two separate labels (not three); one
describing lines 1-7 and the other 8-14. For each of the treatments (A-B) I
want a

lineplot.CI problem
Hi List,
I have a problem plotting data using the lineplot.CI command in the sciplot package.
I want to plot the data of 2 experimental cases using different lines (traces). Time is on the X-axis. The tricky thing is that the data collection in the second case started later than for the first case. This is to say: the first n data points for the second case are missing.
So far so good. However,

In this example, the author uses two colors for the two lines, but the

geom_abline does not seem to respect groups in facet_grid [ggplot2]
Just trying to understand how geom_abline works with facets in ggplot.
By way of example, I have a dataset of student test scores. These are in a data table dt with 4 columns:
student: unique student ID
cohort: grouping factor for students (A, B, . H)
subject: subject of the test (English, Math, Science)
score: the test score for that student in that subject

Hi John,
You can try the following:

="Temperature"))

Change default order of colors & line types
Dear R users,
I'd like to change the default order of colors & line types.
Especially I am using ggplot2 and using color Set1.
In Set1, the default color order is red, blue, green, violet,.. ect.
However, I want to put red in fourth (not first).
Likewise, I want to change the order of default linetype. I want to
put "solid" line in fourth.
How can I do thses?

Adding non-data line to legend ggplot2 Maximum Contaminant Level

Combining several mappings in ggplot2
Hello,
I want to be able to make a plot that has several series with
different color and linetype.
Online documentation suggest that this is possible, but I haven't found how:
"We can also create redundant mappings, mapping the same variable to
multiple aesthetics. This is most useful when producing a graphic for
both colour and black and white display."
Here's what I have to
