I am using QGIS for visualizing the health conditions of elderly living in an old age home, some of the elderly have multiple medical device with them and I want to show them on the map.
Suppose I have one bed for each elderly, I have created a centroid for each bed using
ftool, then I join this label with my csv table, and then use
Style tab in the layer properties.
In the csv table, I have 4 columns named
D and each represent the presence/absence of a medical device. Currently I am using
rule-based in the
Style tab and use
Offset X,Y to fine tune the position of the dots so that they don't overlap with each other completely.
I don't like the
Offset X,Y method, because if I need to change the position of those symbols, I need to do it manually one by one, and I have 30 elderly homes that I need to work on. Is there a better way?
