Within each of the 20 plots, each symbol has a pair of coordinates, one for x value and the other for y value. Now order the 20 plots in any order (subplot order is fine). For each of the four classes, go through the plots and list off the x coordinate and then the y coordinate. For each of the classes this would be a list of 40 numbers: x1 y1 x2 y2 x3 y3... x20 y20
You would have this list of 40 numbers for each class.
Now you can interpret that list of 40 numbers as coordinates in a 40 dimensional space.
Now that you have a 40 dimensional coordinate for each class, you can calculate the distance between 40D points.
If you only have 4 classes like your sample plot then I would not expect you would get much usable information out of it. If you have many more classes then you could start using clustering techniques.
