ggplot make boxplots more wide

Question

[Nona]

Good afternoon,

Could anyone advice me on how to to make the boxplot more wide so that you can actually see the colour of the legend?

Current plot:

Current code:

ggplot(data = metadata, aes(x=location, y=gene)) + geom_boxplot(aes(fill=Day),show.legend = TRUE)

Thank you very much!

If there is no interquartile range in the data then you cannot magically create it. Consider maybe stat_summary(aes(color=Day), geom="line", fun = mean) to plot a line for the mean.

[ATpoint]

geom="point" to make it a dot.

If you have 1 value for each location/day, you will get a line. Prefer just plotting a dot.

What is in metadata ?

[Nona]

Yes its actually just one sample per location / day. Location is e.g. lung and liver and day is day 1,2,3 and gene is gene expression for this location/day.

How can I change it to a dot instead of a line?

Set colour to Day as well:

ggplot( data = metadata, aes(x = location, y = gene, fill = Day, colour = Day)) +  geom_boxplot()

To get more specific answer, please provide example data: dput(head(mydata, 10))

Thank you everyone.
