Values not working in scale_*_manual

[SAI_KIRAN_VOLETI]

While i'm using values in scale_*_manual getting unused value in legend in for loop. Please do the needful.

The below code is without scale_color_manual and the result attached below the code.

Inv_sub_part1[[6]]%>%ggplot(aes(x=RELATIVE_ACT_TIME,y=CONC,group=TRT))+
geom_point(aes(color=QVAL),size=4)+
geom_line(aes(color=QVAL),size=0.86)

When i use the scale_color_manual and I'm getting the additional legend, in previous versions it was not there .
After updating to latest version of ggplot2, it was started.

Inv_sub_part1[[6]]%>%ggplot(aes(x=RELATIVE_ACT_TIME,y=CONC,group=TRT))+
geom_point(aes(color=QVAL),size=4)+
geom_line(aes(color=QVAL),size=0.86)+
scale_color_manual(name="Treatment",
values = c("NON-NULL"="black","NULL"="grey60"),drop=TRUE)

Hi!

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at this guide, to see how to create one:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…
