The KL Group, Toronto, Ontario, has developed what it believes is the first commercial extension to Sun Microsystems Inc’s XView Open Look windowing toolkit. XRT/graph adds plot, bar chart and pie chart objects to XView, and includes a prototyping and development tool called Builder. Builder generates C code from graphs designed by manipulating XRT/graph’s objects, which can then be embedded into other applications. XRT/graph runs on Sun workstations with Open Windows, on X-terminals, personal computers with X Window server software and other workstations supporting X11 release 4. XRT/graph costs from $1,300 and is available now.
