Hello,

This change can be applied with option 'adapt_depth':

draw2d(adapt_depth = 1, explicit(321.4567,x,0,1));

In the following simulation, variable 'tempos' stores execution times
for 'adapt_depth' equal to 1 thru 7:

tempos: [0.528033, 1.012063, 2.128133, 4.592288, 10.476654, 26.369647,
76.280767] $

draw2d(points_joined=true, points(tempos)) $
