ggplot2_Modify axis label, move axis title, multiple graphs together

[FedeMaggio]

Good morning, everybody.
I'm making a boxplot with ggplot2 3.2.1.
I can't understand how to move the titles of the axes further away from the chart and put the black color to the values of the x and y axes. I will then have to make other equal graphs with other parameters and then put all the graphs inside the same graph window.

Thank you very much for your help.

Hi, welcome!

We don't really have enough info to help you out. Could you ask this with a minimal REPRoducible EXample (reprex)? A reprex makes it much easier for others to understand your issue and figure out how to help.

If you've never heard of a reprex before, you might want to start by reading this FAQ:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.2…

Hi,
Yes, I use these codes to create my graph

NO2 <- ggplot(data=data,aes(x=Station, y=NO2, fill=Tide)) +
geom_boxplot()+
scale_fill_manual(name="Tide", values = c("Orange", "green")) +
xlab("Stations") +
ggtitle("Nitrite") +
ylab("µmol/L") +
theme_bw() +
theme(plot.title = element_text(hjust = 0.5))

Thanks
