Hi, Have you tried:

I have many values close to zero and if I use log, they are instantly transformed to negative values and then the bars show above. The sqrt trans worked ok but when I used the pseudo_log_trans, it did the work! Many thanks. Kind regards, Maria Στις Δευτέρα 17 Ιουλίου 2023 στις 04:43:59 π.μ.

It would have worked if it was some small non-zero quantity, but an actual zero is infinitely far down; it won't fit. There is a number of transformations described in help(scale_y_continuous). You may find trans="pseudo_log" or trans="sqrt" useful. help(geom_bar) recommends geom_col() instead of geom_bar() to represent values (not counts of occurrences). We could help you more efficiently if you clarified the relationship between your data (with columns `ID`, `values`, `databases`) and your code (which mentions `Temp`, `mean`, `Glass`). -- Best regards, Ivan ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
