The rough edges include absence of ~addons/ide/jhs/jplotdemos.ijs . I found jplotdemo.ijs and tried it instead. After several iterations of installing addons required by jplotdemo.ijs I was able to do
plotdemo NB. requires JAL graphics/plot and graphics/afm installs NB. requires JAL general/misc and math/misc installs NB. plotdemos 0 through jplot 54 create html plot files plot 10?10 plotdemos 1 plotdemos 10 plotdef 'show';600 300 NB. jhsshow width height plotdemos 10 plotdef 'link';400 200 NB. jhslink plotdemos 25 plotdef 'none';600 300 NB. create ~temp/plot.html without show or link plotdef 'show';600 300 NB. jhsshow plotdemos 54 but none of the listed commands would work correctly with Google Chrome. For example, plot 10?10 led to a window with address http://127.0.0.1:65001/~temp/plot.html and Chrome error message No data received Unable to load the webpage because the server sent no data. Here are some suggestions: Reload this webpage later. Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data. This was a typical response to the commands I tried. However, when I used Windows Explorer to find file C:\Users\Kip Murray\j701-user\temp\plot.htm and clicked on the file name in Windows Explorer, a J Plot window opened showing a jagged line plot passing through ten random points, on a "graph paper" grid with labels i.10 on the x and y axes. So something is working! It appears to me ~temp/plot.html was incorrect identification of the html file.
