I would like to create a dynamic representation of a dataset along the time in QGIS.

I have my data in a layer and a table with a relation from one to many:

TABLE_1 TABLE_2 id_city ---> id_city city year population

My idea is to make some kind of animation that represent the values of population with a range of colors along the time.

To do that I've created a new layer with the geometry of every city duplicated as many times as years and the data of TABLE 2, but I have some doubts...

  • Anyone knows if is there any way to do this representation with QGIS?
  • Is it possible to do it just seting the relation and without a new layer with duplicated geometries?

I have tried the Time manager plugin of QGIS, but as long as i know it shows new geometries along the time, and does not show the same polygon with different values of population (in this case...).

As far as I'm aware, there is no alternative to TimeManager and there you indeed need to duplicated the geometries.
