Plotting Grouped Boxplot with ggplot2

Hi there,

I like to prepare a grouped boxplot for multiple columns (T1 to T6) from DF below. That can show high and low expression at each time point (T1 to T6). The R script I am using shows only one separate plot at a time e.g. T1 for Exp (High and Low). Any suggestions on how I can combine all columns (T1 to T6) to represent in one plot.

ggplot(DF, aes(x=Exp, y= T1, fill=Exp)) +
geom_boxplot()+
labs(x="T time point", y= "Expression")

DF

Exp T1  T2  T3  T4  T5  T6
High    0.23    0.64    0.00    0.09    0.00    0.36
High    0.12    0.00    0.32    0.05    0.00    0.56
Low 0.01    0.47    0.00    0.41    0.28    0.17
High    0.12    0.04    0.29    0.05    0.13    0.49
Low 0.15    0.00    0.24    0.12    0.00    0.59
