VENIX Graphics on the Professional
From Computer History Wiki
To take advantage of the DEC PROs graphics capabilities, VENIX/PRO UNIX has got some special drawing routines added:
* bar draw a bar chart * chart draw a flow/organizational chart * hist draw a histogram * graph draw a graph * pie draw a pie chart * scat draw a scatter graph * spline interpolate smooth curve
Some graphics handling tools have been added as well:
* erase graphics and text screen erase * plot graphics filters * pscreen screen dump to graphics line printer * setscreen set video screen mode
If you use the "demo" login, you get an impressive demo of what is possible using VENIX/PRO graphics.
All of the above has been realized with the Xhomer Professional simulator and VENIX/PRO V2.0.
The same results would have been achieved using a real DEC Professional computer (if I had one ;-)).
