AUTOPLOT V3.0 Menlo Systems 3790 El Camino Real Suite 221 Palo Alto, CA 94306 (415) 856-0727 AUTOPLOT is a program for plotting data using the TRS Model 100 and the small color graphics printer CGP115. The program is powerful, fast and easy to use. I was able to plot a set of X,Y paired data 15 minutes after opening the package. (However I was hung up for over an hour trying to plot two or more curves on the same plot...the DOC's didn't tell me that the curves must have an equal number of points. It is easy to provide dummy points once you know they are necessary.) Options are chosen from a very clever menu. Axes are automatically scaled or may be selected manually. The axes may be marked with hash-marks, extended into a grid, or suppressed. Data may be plotted in MANY forms including curve, dash, box and bargraph. Even "mark and range," with three data points defining a vertical line and mark is provided, e.g. for HI-LOW-CLOSE. Lines, bars etc can be produced in different colors using the four ball point pens of the CGP115. Equations with two or more variables are easily graphed. A single curve with axes is executed in about 30 seconds. Labelling takes longer but is fun and versatile. A Text menu allows you to enter the text string, size, color, emphasis, direction etc. The cursor keys are used to position the starting place for the text, then hit to print it. Any number of labels may be printed on one graph. The standard graph measures 3 1/4" x 4 3/4". Options permit square and smaller graphs. Graph quality is excellent if you keep a supply of fresh pens on hand. The program loads into 10,511 bytes but expands into 15,358 bytes while drawing one curve with 12 points, into 18,574 bytes drawing two such curves. My only complaint is with the DOCs, which are generally good but do not cover all kinds of plots. The X-axis placement of the colored bars on the bargraph plot is neither intuitive nor explained...you must experiment to get the desired result. I called the author to find out how to enter the three Y-values required for "mark and range, (easy...just enter them)! The author was most helpful, and the program more powerful than I had expected. I am not the vendor, but in 3/84 I paid $39.50 + $3.00 S&H for this program, which more than lived up to my expectations. (Satisfied Customer)
