Abstract : A BASIC computer program has been developed for drawing either half-or full-page-size report-quality graphs of externally generated data on a Finnigan 4010 Gas Chromatograph/Mass Spectrometer Data System. Up to five sets of results can be linearly, logarithmically or inversely presented. As well as drawing the borders and printing labels supplied by the user, the program selects appropriate divisions for the axes and scales the data accordingly. Either solid straight lines joining all points or solid or dashed straight lines resulting from an internal linear least squares calculation can be included on the graph. Provision has also been made for the inclusion of threshold lines on the graph if desired and for the separate printing of lines of alphanumeric and plotting characters for use in captions or headings. A listing, flow-chart and set of simplified instructions for its use are included. (Author)
