I have 8 different equations for predictive curves, but included a shortened version of the csv I am working with here:

I have two y axes in a plot and legends to go with each. The right axis for the point is in the plot and the accompanying legend titled “I” here. In the code, it’s the scale_color_manual or color inside of guides(). I want to get rid of the dark grey square that surrounds the point in the legend. I want to keep the legend and the point. I’ve circled the symbol with red in the attached image.

I am creating a scatter plot using ggplot2 with three groups. I am then adding an additional layer to plot additional data. In both cases, I map the data to group, but in the second case I want to legend to be dissociated from groups and just be a binary black and white linetype legend. Right now the legend merges everything.

I would like to make a geom_area plot where the legend shows more colors than there is data for. I’ve provided a made-up dataset below that has two treatments, and I want the legend to show colors for both of them as well as a third treatment. I have read that the “limits” argument of scale_fill_manual can be used to force the legend to have certain values, so I prepared a named vector of values to use in scale_fill_manual, where the named vector will be the “values” argument and the names of that vector will be the “limits” argument.

I have a plot of species richness that has nine lines. I have labelled each line at the end using geom_label_repel() with the appropriate quadrate number. I want to add in my legend a similar black label box with a number 1 or a hash (#) in it with ‘Quadrat Number’ written next to it.

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)
