Using QGIS, I want to display points on a basemap, the color of the point (symbol) I need to change from a 'rule based' expression.
I have loaded a basemap, imported my data, a .csv file containing amongst others a lat column, a lon column and a 'level' column, containing values from -30 to -140.
I have selected 'rule based' and in the 'expression' I have "level" >-108. This puts me a colored dot on the map at the correct point when the value in the 'level field is greater than -108, but what I want is for the dot to be a different color if 'level is less than -108, (there are some other fields that I will deal with later, hence needing a rules based expression).
So, basically, my question is how do I make the symbol a different color depending on the value when using expressions? I have tried color_rgb and symbol_color, neither worked.
