# Angular gridlines in sage plot

 0 My ubuntu sage installation still has some problems. So I installed it on my mac to get started. I was wondering if there is some way to make non-vertical gridlines in Sage. For example, I used show(L,gridlines=True) for some graphics object L. Now I want to rotate just the y axis gridline by 30 degrees. How can I do it? Thanks. asked Jun 10 '11 Yayu 5 ● 1 ● 3

 2 I don't know any option to do that at once, but you can use something like: var('x y') line = 2*x + y p = plot(...) grid = sum(implicit_plot(line+k,...) for k in srange(-1,1,0.2)) (p + grid).show()  to add the grid manually. posted Jun 17 '11 pang 167 ● 3 ● 10 http://www.uam.es/persona...
