###########################
#==========================
# Plot 2: Barplot with scores (unordered)
# corresponds to DUET_outcome
# Stacked Barplot with colours: DUET_outcome @ position coloured by
# stability scores. This is a barplot where each bar corresponds
# to a SNP and is coloured by its corresponding DUET stability value.
# Normalised values (range between -1 and 1 ) to aid visualisation
# NOTE: since barplot plots discrete values, colour = score, so number of
# colours will be equal to the no. of unique normalised scores
# rather than a continuous scale
# will require generating the colour scale separately.
