This method creates a plot similar to the variation frequency plot in Roche's GS Amplicon Variant Analyzer. The plot shows the reference sequence along the x-axis and indicates variants as bars at the appropriate positions. The height of the bars corresponds to the percentage of reads carrying the variant. A second y-axis indicates the absolute number of reads covering the variant.
