Perhaps you need a "movie"? You can use different colours to show the
progression of values at the spatial points as well.

Something I've used in the past to visualise space-time datasets is Xgobi (or Ggobi). Feed it a dataframe of x, y, t, numbers then set up two plots:


 * an x-y plot - the "map"
 * an x-t or y-t plot - it doesn't matter as long as 't' is on one axis.

Now make a long, thin brush so that when placed on the x-t plot it highlights a small amount of t-space but all the x-space. This will then select all the points in a small time-space.

With linked plots, you can either set transient highlighting and see points come-and-go in the map as you drag the brush on the time-plot, or persistent highlighting and then start at t=0 and drag up to t=tmax, showing the birth of points in time building up the final pattern.
