Dear all,
I am having the following dataset
fc<-
ID values databases
Al 0.15 phreeqc
Al 0.6 carbfix
Al 0.47 actual
Ca 7.2 phreeqc
Ca 7.2 carbfix
Ca 0.3 actual
Na 14.4 phreeqc
Na 84 carbfix
Na 106 actual
Cl 22 phreeqc
Cl 21.9 carbfix
Cl 72.1 actual
Fe 0.05 phreeqc
Fe 0.43 carbfix
Fe 1.25 actual
Mg 0.35 phreeqc
Mg 0.17 carbfix
Mg 0.08 actual
SO4 0 phreeqc
SO4 0 carbfix
SO4 416 actual
As you can see, the values range from 0 to 400. I want it to plot it in bars; when I am plotting it as you can imagine the values near zero don't show at all. So I am trying to make the y axis logarithmic. I have created the following code but it doesn't work. I get the bars with zero above and the others on top.
ggplot(fc, aes(x = Temp, y = mean, fill = Glass)) +
geom_bar(stat = "identity", position = "dodge", aes(y=log(mean)))
+ theme_bw() + theme(panel.grid.major = element_blank(), panel.grid.minor = element_blank()) + theme(legend.position = c(0.45, 0.85), legend.title = element_blank())
+ scale_fill_brewer(palette = "Dark2") + scale_color_brewer(palette = "Dark2")
I would very much appreciate your help. I am stuck.
Kind regards,
Maria
