d = {
    'x': [1, 2],
    'y': [0, 0],
    'c': [1, 2]
}
ggplot(d, aes(x='x', y='y')) \
    + geom_point(aes(color=as_discrete('c', label="CCC", levels=[2, 1]))) + ggtitle("label='CCC', levels=[2, 1]")

Expected - legend title "CCC" with legend rows 2 and 1

Actual - rows order is 2 and 1, but title is "c":
