I would like to create a 4-D plot with points with different sizes for the fourth dimension. The first three dimensions are years, regions, and types of land covers. The fourth dimension contains the area for each specific land cover for regions in different years. I want to create a 4-D plot with three axes using years, regions, and types of land covers. I want to show the fourth dimension with points with different sizes corresponding to their area for each specific land cover for different regions and years. Python or Matlab preferred. Thanks in advance!!
I found a few references for creating a 4-D plot with different colors for the fourth dimension, but I want to creat a plot with points with different sizes instead of different colors.
