|Simple Plot calculates DNA sequence composition using a sliding window that moves along the sequence at 1 bp intervals. The results are returned as a set of ranges and y-values. The range is the group of bases used in the calculation, and the y-value is the result of the calculation. A horizontal bar proportional in length to the y-value is also shown. Use Simple Plot when you are looking for segments of a DNA sequence with a particular base composition, rather than a specific sequence of bases.
