hi Richard,
thanks for reply.
The way of Categorized Style surely make the dot seem different.But I
hope to put all thing predefined in that csv file,because
I need output the csv from another software and then import qgis to get the
glance of whole state of these dots.This operations will be a little bit
more frequent and the dot actually has three or more different states,so I
want to simply the operations as much as possible.
I guess put everything in that a single file is a simple way but i dont't
know wether it is feasible in QGIS?
