enter image description here

what I wanna do is extract some information from this graph. little bit about this data is the x is the amount of stuffs that ppl buy and y is how much they pay. and the colors show the different genre of stuff.

I thought use k-means to cluster theses data by genre using x and y but I'm not sure. Multiple regression might work as well but first I need you guys to tell your thoughts.

pls tell me any ideas about this graph

Depends on what you want to do.

  1. Regression: predict average price or amount given that you know the kind and the other value.
  2. Classification: given the price and amount, predict the type.
  3. Clustering: forget that you already know the kind, and try to rediscover it.

Clearly, as you already have the colors, 3 does not make much sense. But I doubt that either 1 or 2 is particularly interesting on this data either. Looks very much fake data anyway. But you'd need many more attributes to find any interesting learning task beyond computing the average price/quantity for each genre.
