I am using QGIS version 2.14.1 (Essen). I have symbols that I have classified according to certain value from one of the columns in my shapefile.
Is it possible to do a second classification according to a second column?
Basically, I am using data with road works and the deviations linked to roadworks. My first classification is according to the size of the roadwork and I would like the second one to be according to the type of deviation (for cars, pedestrians, buses, etc).
