I’m trying to remove the gray box behind the color icon in the legend of this graph. Wondering if the issue is that I’m using geom_col() so the color aesthetic is just the outline of the column. Does anyone know if I can keep my use of geom_col() and just remove this background?

I am trying to modify my figure legend to change the title of the legend and the item names within the legend. The code noted below will not change the names, the figure remains the same. We have tried using fill = SamplerNum instead of color = or group = and then it removes the legend and makes the lines on the graph grey. Have also tried scale_color_manual and guides() (see guides() code below)

I’ve put together this graph and I would like to be able to add a legend to it but can’t seem to figure out why it’s not showing up and how to easily add it.

I have the following graph.

I have a data set with a big negative value, so I used gg.gap package to make a discontinuous y-axis. The code worked well but after adding the function gg.gap the legend was deleted.
I tried adding a legend using the add.legend argument but it didn’t work.
Am I doing something wrong?
Here is a sample code

Is there a way to change the orientation of the items in the legend of ggplot2 chart?

I have a problem making the plot legend to show. I’ve checked other posts and most of them mention that color should be defined within the aes() of the ggplot.

With the following data, I am trying to create a plot as shown, but the order of legends as: mgCST Group, CST Group, Treatment Status. However, ggplot is ignoring all attempts to order the legends
