Abstmct: 72PLOT is a software suite designed to drive the Hewlett-Packard 7202A X-Y digital plotter to produce graphs with data points (any ASCII character, or special graphpoint shapes), or as lines between data points, or as a histogram plot. The user can select all axes parameters (scales, logarithmic or linear, linear increment etc.) on a variety of axed formats, and define a graph title and X and Y axes titles. A simple linear regression analysis permits plotting of the best straight line on a scatter diagram. For the histogram option, a Gaussian curve equal in area to the histogram can be drawn. Original data can be disk, tape, or keyboard sourced; output can be the plotter, disc or tape. An accessory program allows reorienting of the plot (from a prepared plot file) to give a vertical rectangular format. For accurate scientific graph plotting, a graph paper option is included which allows plotter settings to be aligned with printed grids.
