I have a barplot with smoothing lines from ggplot. But for some reason, blue lines appear in the legend on top of the barplot colors and I don’t understand where they come from and how to remove them. Especially because it is a shade of blue I did not use in the code.

I have a bar plot using ggplot() in which I have truncated the y-axis using coord_cartesian() so that differenes between the bars are more easily visible. In other words, the y-axis does not start at 0. I want to highlight this adjustment by adding two parallel diagonal lines in the lower end of the y-axis. How can I add these so that they are visible even in the negative quadrant?

The data and code for this question were adapted from:

Data set
I want to make a group bar plot with ggplot. but i want to reorder the bar according to the specie, for example first bars belong to sp1 and then sp2 should be shown in a decsending order in the graph.
So far I am able to plot the graph like this

but genotype belong to sp1 should come first and then genotype belong to sp2.
I am using this code

I’m graphing a large number of bars in a barplot (>1000), and want to color a subset of them black to highlight them. However, with this large number I run into what I think is an issue with screen resolution. When I zoom in some black bars appear or disappear (notice the rug plot without corresponding black bars above it), and white bars appear (which should not be there).

I created the bar char as below:

Basically, I have a dataset with three variables im interested in plotting. One is called subgroup which has the name of subgroups that the strains belong to. At least two of them share the same subgroup. Currently, when I bar plot them,and fill by subgroup I get coloured bars accroding to the subgroups but they dont appear next to eachother (and instead do by strain name in alphabetical order). I want a barplot that has any strain from the same subgroup together.

library(ggplot2) series <- data.frame( time = c(rep(1, 4),rep(2, 4), rep(3, 4), rep(4, 4)), type = c(1984:1987), value = rpois(16, 10) ) series %>% ggplot(aes(time, value, group=factor(type, levels=1987:1984)))+ geom_col(aes(fill= factor(type)))+ guides(fill=guide_legend(title=”type”)) I want to reorder the order of the fill between different groups, like the figure below that I have edited in Paint. How can I […]

I want to rearrange the bars in the following graph. i want to show CT and HS bars side by side , for example first 1DAS CT and HS bar then 15DAS CT and HS bar and so on. I am using the following code

That is a random data
