Barplot in 2.2.2 BA

[nmprista]

barplot does not run with setting cum_percent == 95 or NULL
for NULL issue is solved with x<droplevels(x) but this may be inconvenient (reduces x scale to available values - e.g., not all countries show up (*)
issue may be related to ifs involved in setting up colour _scale

(*) - this option is still worth adding as argument
