I'm colour blind so there's basically only three colours on this graph but what I'm assuming is showing is that windows is decreasing in popularity and apparently so is OS X. I'm assuming the other colour is Linux or Chrome but no idea which is which.
For future reference, when making graphs make them in black and white first and if they are visually distinct then you can add whatever colours you want.
