I have subset a shapefile of points to only include those having a value of (for example) 33 in the variable "Bout" using a rule based assignation:
Now I would like to apply a sub-category to that rule which colours the points by date like so:
However this uses the range of the original data rather than the range within the subset. Is there a way to only spread the colour values across the range of the subset data without manually creating each category? It is doable by simply removing the values from the sub-category manually and recalculating the value-based colours but I was hoping for a more elegant coded solution as I am a python amateur.
