Hello everybody,
Is it possible to have multiple colors in the same layer based on the value
of the class item.
for example if I am using the humidity in soil as a factor , i would like it
to show different color for different values.
I am familiar with EXPRESSION to filter but how to use it for classifying data.
Vishal
