python - Animating a geographical heatmap
问题描述
I am using Python and I would like to represent a set of time series on a heatmap.
My static representation of the geographical space, which is a "fixed-time slice" of all the time series, looks like this:
Each time serie corresponds to a cell, and every cell is associated to a specific geometric shape on the plot above. Here is an example of one of the time series:
Is there any way I can "animate" the heatmap above or at least set a time parameter that I can regulate in order to see the time evolution of the entire map? Obviously the arrays have all the same length and are stored as NumPy arrays in a DataFrame like this:
SQUAREID

and SQUAREID is matched with the cellId column in a GeoDataFrame that looks like this:
