[mapserver-users] Mapserver - classifying multiple symbol sizes with multiple colours [SEC=UNCLASSIFIED]

[Inna Nogeste]

I need to symbolise data showing both size and colour, where there are 4 different symbol sizes and 11 different colours. The 11 colours can be applied to all 4 different symbol sizes.
Is there an efficient way to code this or do I need to have 44 different styles/expressions such as the following:

EXPRESSION ([size] = 1 and [colour] = 0%)
EXPRESSION ([size] = 1 and [colour] = 10%)
EXPRESSION ([size] = 1 and [colour] = 20%)
EXPRESSION ([size] = 1 and [colour] = 30%)
to
EXPRESSION ([size] = 4 and [colour] = 100%)

In addition to this, I also need to scale the symbol [size] for different zoom levels which will increase the number of styles/expressions by a factor of at least 2 or 3 resulting in at least 88 blocks of code.

Does anyone have any suggestions for the most/a efficient way to code this?
