This function employs rc.plot.histogram
to plot heat-map. Every row of Data
will be plotted as heat-map in one track. The column names of Data
must be the chromosome ids.
If color.gradient
is not NULL
, the data will be scaled to positive integers in the range of 1~length(color.gradient) to index the colors in vector color.gradient
. If color.gradient
isNULL
, the input Data
must be a matrix of colors or anything that can be converted to colors.
