I have plotted a triangular plot,that three dimensions of which represent three herbal strategies. One dimension represents the strategy of C (competitive plant), the second dimension “S” (stress tolerant plants) and the third dimension”R” (ruderal plants), as you can see in the image below,[![enter image description here][1]][1] the points on it represent the plant species. Now I am trying to write name of the plant species outside the triangle and connect with the arrow to the corresponding point. How do I do this work? Many thanks in advance as it would help me a lot in my work.
