In IRC we updated the page with a CQL example (I did not understand that
Interpolate was causing problems as an example; I was just using it as an
example of how to use Parameter):
If you are interested the above interpolate function can be used as in
this CQL example (to repalce a lot of code you often use Rules for):
Interpolate(POP_CNTRY,
0,'#ffffff',1000000,'#cccccc',10000000,'#9999aa',1000000000,'#5555ff',''linear','color')
Note the "table" parameter must have a minimum of 4 values to form an
interpolation range. The above example has 4 pairs forming three smooth
gradients. Choosing a different MODE would result in a smoother shift
between the gradients.
