I have a point vector layer with several attributes in QGIS Dufour.
One of them is satellite name, and the other is date. I want to display different dates with different colors (using some gradient) while the satellite name rules the type of symbol.
For example GOES-13 is a square, AQUA a dot, TERRA a triangle.
Satellite date
goes-13 01/01/2014
goes-13 01/01/2014
aqua 01/01/2014
aqua 01/01/2014
terra 02/01/2014
… and so on
I know how to change the size or rotation of the symbol, but not the type.
