chromosome distribution without centromere

Introduction
Chromosome distributions of peaks, SNPs, genes.
Input data instructions
Chromosome length data contain two columns: the first column is chromsome name, and the second column is length.
Genomic location data contain 3 columns (column 3 is optional): the first column is chromosome name, the second column is location and the third column is categories, such as up, dn. At most 6 categories, i.e. 6 user-defined colors.
