text: user285: I'm trying to replicate the figure given in this paper using this table which they have given.
  
  So what i understand from the figure is they have calculated the zscore between two condition and plotted the same.
  Now How is the length of each bar which is the peptide here is variable is it the zscore or the actual peptide length?
  Small subset of the data

  Any suggestion or help would be really appreciated
  
  user14577: The length of the bars and their placement on the x-axis represents the length of the peptide and mapping to the source protein, respectively. The coloring represents the average difference in peptide MS intensity between the control and two experiments.
