Thanks for all who replied to my request for information on programs to convert graphs or plots into data. Here are some of the replies -- from dana@are.berkeley.edu (Dana E. Keil) >"Turn Graphs into Numbers" with FlexiGraphs, Tree Star Inc., >1802 Hillside Rd., Santa Barbara, CA 93101 (805) 682-4096. >Toll-free number (800) 366-6045 >The above is from the handout I got when they came to show off >the program at BMUG. Everyone was pretty impressed with it. As luck would have it, MacWeek reviewed FlexiGraphs the week after my question. It seems that this program can convert a line drawn freehand on a graph into some sort of mathematical relationship and extrapolate projected values. However, it cannot convert plotted points into data. I called Tree Star and was told that they will soon release a new program called Datascan, which will convert a scatterplot into numerical data. I was informed that Tree Star intends to bundle Flexigraph and Datascan both for about $99. This sounds like a good deal. Meanwhile FlexiGraphs is available discount from Mac Zone, Egghead, and Computerware. Kees Huyser <keeshu@nikhefk.nikhef.nl> at the National Institute for Nuclear Physics, Netherlands, has written a program called DataThief, which he was kind enough to send me to test. This program opens a Macpaint-format, scanned image of a scatterplot and, after you input the range of the x and y axes and click on the points of interest, outputs a table of numerical values of x and y values for the points. I have tested the program and it performs these functions admirably. Also, humorous opening screen and sounds! It also has some capablility for handling error bars, but I did not test this function. This program is free but not in the public domain. I am submitting it to sumex. Other possible leads ... from Roman Kanala, CUEPE, Univ Geneva, Switzerland, kanala@sc2a.unige.ch >I think that the company was Abacus Concepts (formerly Computer Brainware >Advisors, but am really not sure). >Street address as on May 1990: >1984 Bonita Avenue, Berkeley, CA 94704, 1-800-666-STAT from aron@garnet.berkeley.edu (Aron Roberts) >I believe the vendor of this product is Brainpower in Agoura, CA. >They're the same software company that marketed the original StatView, >so you should be able to find their number in some older Mac publications >if not from directory information.
