[Gnuplot-info] Weird Gnuplot problem

[Dave H. <da...@ho...>]

Gnuplot 5.0.4, on MacOS 10.11.6.

For reasons that are not particularly germane, I am trying to determine 
the area of a square vs. a circle, given a piece of string of length "x".  
I have worked it out in simple maths, but I want to plot it.

gnuplot> set xtics 0,1,100
gnuplot> plot (x*x)/16, pi * x

But no matter what I do, I get a partial graph, no xtics on the left, 
extending to 10 on the right, with the expected parabola and angled line 
intersecting at x=0.

What I really want to see is the parabola crossing the straight line, 
around pi * 16. so where have I stuffed up?

Thanks.
