Hello,

Is it possible to table the top five, say, countries per continent?  To take the Insight Toy online example, would it be possible to select the top 5 countries by Gross Margin per continent -- which would mean 5 * 6 = 30 countries overall.

Having done that, would it be possible to highlight only those countries on the world map?

And given the huge dominance of the US market in that example, would it be possible to shade those countries on a logarithmic scale?  The linear scale results in only two colours.

Thanks.
