You have to decided whether you want one single plot or 23 plots (one
for each chromosome). Since I suspect that, say, copy_num at the end of
Chromosome 1 and the copy_num at the start of Chromosome 2 are not
related (like time series data) and would suggest 23 plots instead.

Dear all.
I need to draw a scatter plot of 23 chromosome copy numbers (y axes) against
chromosome and physical location within each chromosome in one plot. The
data matrix looks as below:
chr location copy_num
1 118345 1.320118
1 3776202 1.133879
1 4798845 0.989997
1 5350951
