Although I am not claiming to be the inventor, as far as I knew, this was the first time when digital computer was used to draw such plotting with line printer which fed continuous paper only in one direction. As soon as I presented its plotted results at a conference of SCI, this plotting subroutine was copied immediately among simulationists, and spread like a wild fire in the dry hay field -- a forerunner of shareware -- the rest is the history. It was a kid's play compared with nowadays' dazzling multimedia graphics on a desktop computer.
With my previous experience with analog computers, such graphical plotting was by nature. However, other colleagues who never had analog computer experiences clung with tables of rows and columns of numbers printed by digital computer. They insisted to have many digits by digital computer, even though 3, or at the best, 4 digits were mostly good enough in chemical fields due to crude measurement equipments. I learned how difficult it was to change "mind" for new technology, even among high-tech specialists on computer programming.
When I went back to Japan in 1972, I was surprised to find that Japan Club of Rome led by a professor of the University of Tokyo used MIDAS to simulate world dynamics in three dimensional mode, i.e., with the use of a mathematical model which consisted of several partial differential equations. They were several years behind of the U.S. on the use of simulation languages, and their use of partial differential equations were mere mathematical play -- not simulation, since there is no continuous diffusion of socio-economic activities across national boundaries, except climatological consideration. Yet, a Japanese industrial group led by Koji Kobayashi, then CEO of NEC and a senior alumni of my Matsumoto junior college, spent millions of dollars to support their activities.
Such misleadings of the Japanese national policies and projects by the graduates of the University of Tokyo were common; e.g., (a) the designs of the world largest battleships, Musashi and Yamato, of Japanese Navy were led by Rector Hiraga of the university, which big guns were no use when aircraft was a major decisive factor -- they should had been converted to aircrafts, (b) Japanese Zero fighter pilots were surprised to find American and British fighters already waiting when they flew to Manila, Philippines or Singapore. They later found a strange electronic equipment in their air bases, and that was a radar with Yagi antenna invented by the president Hidetsugu Yagi of my alma mater, Tokyo Institute of Technology, which later became household use for TV reception throughout the world. A TV documentary told me that, since Japanese Navy did not have the radar, they lost Midway sea-battle which became a turning point of the World War II, i.e., Japanese lost their war because they did not use their own technology effectively, (c) now defunct NHK's analog-oriented High Definition TV (HDTV) project with $3 to 5 billion dollar R&D funds, (d) the 5th Generation Computer project with $300 to 500 million dollars, (e) political and financial scandals of Japanese Ministry of Finance and prominent banks and security firms such as Sumitomo, Daiwa, Dai-ichi Kangin, Nomura, etc., etc.
No body whistles a blow to them lest they should risk their lives -- in Japanese society, such whistle-blowers were often assassinated or murdered by mafia (yakuza) -- see "BlackMail" in Business Week, July 21, 1997, Page 42-43.
Similar incidents: When I attended the national conference of Fulbright Association in Washington, D.C. a few years ago, an elegant lady approached me and thanked me earnestly. I could not get why. She was expressing her sincere gratitude for the deed what Mr. Sugihara, Japanese Consulate General in Lithuania, did for Jews just prior to the World War II. He issued visa to thousands of Jews so that they could escape the holocaust of Nazi, via the Siberian railroad to Japan and then to Shanghai or Hong Kong. Since he did so against the instruction from the Japanese Ministry of Foreign Affairs (which minister, Mr. Matsuoka, made a Japan-Germany pact with Hitler), he had hard time to find his living after he came back to Japan at the end of the war.
I told the lady of his aftermath, and said to her that I was also in the same situation, e.g., a black sheep among Japanese or even expelled from her society, after expended my efforts of extending U.S. data telecommunications networks to Japan and of de-regulating the Japanese telecommunications policies on the use of e-mail. The lady then said to me with a solemn face, "That's because you believed in the Absolute God!" I was shocked to hear that, because I did not tell her that I was educated to be a Christian by my mother who was educated by the father of Ambassador Reischauer at Tokyo Women's University and was one of the close disciples of Kanzo Uchimura, who was educated by Professor Clark from Amherst College and who originated the so-called "Mukyo-Kai = non-churchism" Christianity in Japan. After hearing her voice, Bible's words flashed my mind; "Blessed are those who hunger and thirst for righteousness, For they shall be filled" and "Bless are those who are persecuted for righteousness' sake, For theirs is the kingdom of heaven." I felt that I might have lived to fulfill God's will.
