    Abstract: A method and apparatus for merging specifies an inset chart shape and at least two chart scale values. A chart retriever retrieves data files defining a low-scale chart and a high-scale chart, and a chart processor identifies portions of the low-scale data files from which data is deleted and merges the modified low-scale data files with high-scale data files which provide high-scale data for the inset chart shape.
