How to control the marker size in "scatter_density"?

I have the same question?

Hi, I just started to use this package as well. What do you mean with marker size? Do you mean how fine the grid is? There is a parameter called dpi which changes the grid size, see the two images bellow. The first one is with dpi=30, the second with dpi=20.

Hi, @scimax How do the values of "density", i.e. color bar, change with dpi?

[scimax]

Well, due to the more coarse binning there are more scatterers in the bin with the highest intensity:

dpi=30 case: dpi=20 case:

Thank you for your answer @scimax. By the way, if the units of x-coordinate and y-coordinate are kilometers, is there any way to express the density as "per square kilometers", i.e. km^{-2}?
