Subplots
The “subplot” mark would essentially be a faceted plot specification within an existing plot, but with facets positioned arbitrarily by an anchor in x and y, and with a fixed width and height. The subplots would share the same scales.
"The subplots would share the same scales."
I would very much like if I could have different scales (I guess that means axis-ranges?) in the sub-plots. The way this is done in Matplotlib is to specify whether the sub-plots should share the x and y axis ranges. Perhaps this would be possible here as well? Thanks!
I agree that it would be really useful to have subplots with different scales (or at least one different axis for my use case).
For example, I want to have several plots of time series data with over the same time scale as the x axis, but each with a different y axis. This is an alternative to having a plot with two (or more) y axis scales which is a common anti pattern in data vis.
