I know that I can create a choropleth by using the styles panel:
Basically, I pick a column attribute, choose the classification mode, and classify. This results in the legend as pictured above. However, this is bin distribution off of one attribute
POP1990, in this case the population in each state in 1990. I have attributes
POP1993, and so on. I can individually classify them, and get 4 different bin distributions. But I want to get the bin distribution off of all
POPYEAR columns so that they share one legend (like the small multiple example linked above). Is there a way to do that?
Basically, I want to create 4 individual choropleth maps per year, but I want the legend that they all use to be the same. Is there a way to do this? I know that there is this expression dialog:
But I'm not sure how I would use this to accomplish what I want. I saw this about creating small multiples with virtual layers, but I'm still not sure about the legend.
I'm new to QGIS.
