There was an alternative - the Calcomp plotter. You wrote commands to move a pen around with the tip either up or down and could draw whatever complexity of graphics you needed. In my case, when I did my M.Sc. in 1971 I was developing a continuous simulation hydrologic model that could calculate flows at a point on a river over a long period of time using various meteorological data. It had a version which produced hourly flow estimates. With maybe 20 years of data, the hourly output was a lot of numbers. To illustrate the results for my thesis, I plotted a graph of the observed flows and the simulated flows on the Calcomp plotter. The x-axis was about 8 foot long. The first time it ran, the plotter operators turned it off as they thought I'd programmed an infinite loop and was going to ruin an entire roll of their very expensive plotter paper!
