How do i reorder the bars in a grouped barplot
I want the bars to be in the order:10% runoff, 20% runoff, NOEC, LC50. Thank you in anticipation.
Below is my code:
ggplot(pest_ana, aes(x = Pesticides, y = `Concentration (ug/L)`, fill= Concentrations)) +
geom_bar(stat = 'identity', position='dodge') + scale_x_discrete(guide = guide_axis(n.dodge=2)) + scale_y_continuous(trans = log10_trans(),
breaks = trans_breaks("log10", function(x) 10^x),
labels = trans_format("log10", math_format(10^.x)))
Pesticides Concentrations Concentration (ug/L) Individual
Cypermethrin NOEC 4.8 1
Deltamethrin NOEC 3.37 2
Actara NOEC 20000 3
Carbofuran NOEC 40.6 4
Methomyl NOEC 260 5
Endosulfan NOEC 10.2 6
Fenvalerate NOEC 6.02 7
Glyphosate NOEC 5000 8
Mancozeb NOEC 301 9
Cypermethrin LC50 0.03 1
Deltamethrin LC50 0.032 2
Actara LC50 322000 3
Carbofuran LC50 500 4
Methomyl LC50 4015 5
Endosulfan LC50 0.05 6
Fenvalerate LC50 15 7
Glyphosate LC50 36800 8
Mancozeb LC50 11680 9
Cypermethrin 20% runoff 3.95 1
Deltamethrin 20% runoff 0.69 2
Actara 20% runoff 3.95 3
Carbofuran 20% runoff 78.99 4
Methomyl 20% runoff 10.86 5
Endosulfan 20% runoff 41.47 6
Fenvalerate 20% runoff 8.85 7
Glyphosate 20% runoff 14.22 8
Mancozeb 20% runoff 74.05 9
Cypermethrin 10% runoff 1.97 1
Deltamethrin 10% runoff 0.35 2
Actara 10% runoff 1.97 3
Carbofuran 10% runoff 39.49 4
Methomyl 10% runoff 5.43 5
Endosulfan 10% runoff 20.73 6
Fenvalerate 10% runoff 4.42 7
Glyphosate 10% runoff 7.11 8
Mancozeb 10% runoff 37.03 9

you need to make Concentration (ug/L) as a factor, with levels ordered according to your need
pest_ana[["Concentration (ug/L)"]] = factor (pest_ana[["Concentration (ug/L)"]] , levels =c("0% runoff", "20% runoff", "NOEC", "LC50"))

Hello Efolorunso!
We believe that this post does not fit the main topic of this site.
Please browse the web on how to change order of bars in ggplot.
There are many threads on that in StackExchange.
You will have to set the levels of the column to the desired order.
