[sage-support] Contour plots of data points...

Hi all, I've looked at the help files for contour plots: http://www.sagemath.org/doc/reference/sage/plot/contour_plot.html and it's very clear how to produce contour plots of functions but I'm struggling to produce such a plot of data points. The example in the help file is as follows: sage:

FYI, I have not had a failing jmol for well over a year on Linux - Gentoo Linux x64 and Ubuntu minimal 11.10 (which was earlier 11.04). In both machines I run sun java. Currently on the Gentoo machine the java is sun-jdk-1.6.0.31. On Wednesday, April 11, 2012 10:23:11 PM UTC+8, Benjamin Jones w

Did you plot it and see the graph? Maybe this is not the graph you wanted? The following command will plot the graph for you (it looks strongly connected to me). d1.show() On Thursday, April 12, 2012 9:55:59 PM UTC+8, Samah Mohamed Osman Hassan Taha wrote: > > Hi > > sage: d1 = DiGraph({0:[1,

[sage-support] is_strongly_connected bug for directed graphs

Hi sage: d1 = DiGraph({0:[1,2],1:[2],2:[1,0]}) sage: d1.is_strongly_connected() True This graph should be connected but not strongly connected, by http://en.wikipedia.org/wiki/Directed_graph#Digraph_connectivity Or does Sage define strongly connected for digraphs differently? Regards, Samah --
