A logarithmic scale won't work when the range of numbers to display
includes 0. 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`).
