Improving the visualization of my bar chart (ggplot2)
how should I improve the visualization of my bar chart (as attached), I would like to label my x-axis with specific time points (0, 0.5, 8, 24, 48) instead of the default value as shown in the image. In the image, the bars are packed and quite close to each other at 0 and 0.5 time point, also the bars' width are so narrowed and thin to the extent that they are hard to be differentiated between different factors. My script is as per below, thanks in advance! p.s. I'm a beginner in R
ggplot(data=Exp1, mapping = aes(x = time, y = npq)) +
geom_bar(stat = "identity", aes(fill = growth_condition), position = "dodge") +
labs(title= "NPQ", x= "Time (hours)", y="NPQ", fill= "Growth condition")
Solution
"aes(x = time, y = npq)" to "aes(x = factor(time), y = npq)"
