gvSIG-Desktop 1.10. User Manual
It is a tool which allows thematic cartography to be carried out with relative ease.
You can choose the colour, mesh etc. which most appropriately symbolises or represents the data or variables of the elements to a layer.
To access the edit option of properties related to the symbology you must go to the “Properties” menu (click on the smaller button on the layer).
Another window will open, place the cursor on the “'tables of symbols' tab".
