This week I was using Sage on cocalc.com to generate some graphs for a Calculus I final. Earlier in the semester, I had generated some graphs with discontinuities and I used the point() function to draw some open circles and closed circles that denote closed and open endpoints of a graph segment, respectively. I was surprised to find that the commands that worked earlier this term no longer worked. Specifically,
p1 = plot(2*x, x, 0, 1) p2 = plot(-x+3, x, 1, 2) p3 = plot(-(x-3)^3+2, x, 2, 3) pt1 = point((0, 0), rgbcolor='black', pointsize=30) pt2 = point((1, 2), rgbcolor='white', faceted=True, pointsize=30) pt3 = point((1, 3), rgbcolor='black', pointsize=30) pt4 = point((2, 1), rgbcolor='black', pointsize=30) pt5 = point((2, 3), rgbcolor='white', faceted=True, pointsize=30) pt6 = point((3, 2), rgbcolor='black', pointsize=30) (p1+p2+p3+pt1+pt2+pt3+pt4+pt5+pt6).show(xmin=0, xmax=3, ymin=0, ymax=3) no longer generates an open circle for either pt2 or pt5. Is there something in the most recent version of Sage that has changed this functionality? I managed to work around this problem with the circle() function, but I wanted to put this question out there in case it's an unintentional 'feature' of the new version of Sage.
