Thanks for your advice, but my data is not decimals, so I don't need to round the values. Instead, what I need to really do is "group" the values into larger "blocks".
My data looks sort of like this: x y z 0 0 687 0 1 64 0 2 71 0 3 55 0 4 52 0 5 51 0 6 38 0 7 38 0 8 54 0 9 49 ......... ......... ......... 987 988 1 999 998 1 999 999 1 But what I need to do is make it so that on the graph rather than having tiny little dots for each point (as shown in the bigplot diagram), there are bigger points, so say 0<=x<10, 0<=y<10 is one point in the lower left, rather than having 100 points for each x,y value. The same strategy should then be applied to the whole graph. Any ideas how to achieve this? I'm sure this is quite a common thing to do want to with heatmaps??
