I'm having a little problem when generating the graph for the day 03/07, category ABC. Note that the two graphs I can generate normally, but the last graph not. This happens because I have values equal to zero for this date/category, so when it comes to `datas`

, it's was `NA`

. However, I would like to generate a graph when this situation occurs, with a point at 0 and a red line at 0, similar to the other images. I believe that to solve this it must be some small adjustment, but I couldn't do it. I appreciate any help!

Executable code below:

```

df1 <- structure(

Category = c("BCE","ABC","ABC"),
Week= c("Wednesday","Thursday","Friday"),
DR1 = c(11,5,0),
DR01 = c(10,4,0), DR02= c(2,4,0),DR03= c(0,5,0),
DR04 = c(2,4,0),DR05 = c(1,6,0)),
