How to define different colors for different edges?

Hello evrybody,

I have an electrostatis pde model with the geometry ilustrated below (pdegplot, "EdgeLebals"=="off", 16 edges). I am wandering if there is any way to define line colors for the edges? I have checked in the Property Inspector, that the plot consists only one line object for the model geometry.

Thanks for any help,

Beata

If you can get the coordinates of the line endpoints, you can use the line function to overwrite that shape with colors of your choice.

 LINE Create line
    LINE(X,Y) adds the line defined in vectors X and Y to the current axes.
    If X and Y are matrices of the same size, line draws one line per
    column.
    
    LINE(X,Y,Z) creates lines in three-dimensional coordinates.
 
    LINE('XData',x,'YData',y,'ZData',z,...) creates a line in the current
    axes using the Name,Value pairs as arguments. This is the low-level
    form of the line function, which does not accept matrix coordinate data
    as the other informal forms described above.
 
    LINE(...,Name,Value) specifies line properties using one or more
    Name,Value pair arguments.
    
    LINE(container,...) creates the line in the axes, group, or transform
    specified by container, instead of in the current axes.
    
    H = LINE(...)  returns a column vector of the primitive line objects
    created.
 
    Execute GET(H), where H is a line object, to see a list of line object
    properties and their current values.
    Execute SET(H) to see a list of line object properties and legal
    property values.

Thanks, I thought about this but hoped, there is another way using the pdegplot function. With the line function I need to know which Vertex is an endpoint of wich Edge. I created the shape as a superposition of rectangles. Mayby it would be better to define it as a parametric curve?
