heatmap with varying size boxes?

Hello,

I have a list of X,Y coordinates and a ratio associated with each
coordinate. The X and Y coordinates are continuous but random from
50-500, I would like to make a continuous heatmap of the ratios at each
coordinate. One caveat is that the coordinates are clustered together
do some bixes might have too little data. I am wondering if there is a
way that R can automatically adjust box sizes? Sample data set is below

TIA

X Y RATIO
50 56 .1
50 59 .1
52 54 .2
500 393 .9
450 36 .7
250 190 .7

I'm not sure about R, this is a Python mailing list :slight_smile:

Are you trying to do something like this
http://matplotlib.sourceforge.net/examples/pylab_examples/scatter_demo2.html
or to interpolate your data from scattered points onto a regular grid?
