# This demo draw human chromosome ideogram with ticks. Since in most
# cases ticks are not necessary for data presentation, we add ticks
# to existing ideogram instead of plotting an ideogram with ticks.
#
# Set 20 tracks inside of chromosome ideogram to get enough space
# for all chromosomes with ticks in 5MB interval
