Re: How to roll up multiple Line calls into a loop

Show all headers | View raw

Hi,

or as an excercise in Part (although the Cases approach is more versatile):

g = Graphics[{Line[{{0, 10}, {1, 0}}], Line[{{0, 9}, {2, 0}}],
    Line[{{0, 8}, {3, 0}}], Line[{{0, 7}, {4, 0}}],
    Line[{{0, 6}, {5, 0}}], Line[{{0, 5}, {6, 0}}],
    Line[{{0, 4}, {7, 0}}], Line[{{0, 3}, {8, 0}}],
    Line[{{0, 2}, {9, 0}}], Line[{{0, 1}, {10, 0}}]}];

g[[1, All, 1, -1]]

Out[3]= {{1, 0}, {2, 0}, {3, 0}, {4, 0}, {5, 0}, {6, 0}, {7, 0}, {8,
  0}, {9, 0}, {10, 0}}

Regards,
Yves
