d3.js Radar Graph - filling in between lines

Question

I\'m trying to create a fill in between two of these triangles, for example a red fill in between the red and green triangles. Does anybody know how to accomplish this? I have s

Answer 1

To achieve this, you'll have to merge the two triangles into one path by using a custom path generator. Then you can close the path and fill it. Note that if you want the triangles to have different colours, you need to draw them separately.

You could try to cheat and simply fill the bigger triangle and then put the smaller triangle with a white fill on top of it. Then draw the grid lines. This will only work however if the triangles don't overlap.
