Specifying the Color and Size of Lines

You can control a number of line style characteristics by specifying values for line properties:

• LineWidth - specifies the width of the line in units of points.
• MarkerEdgeColor - specifies the color of the marker or the edge color for filled markers (circle, square, diamond, pentagram, hexagram, and the four triangles).
• MarkerFaceColor - specifies the color of the face of filled markers.
• MarkerSize - specifies the size of the marker in units of points.

For example, these statements,

• x = -pi:pi/10:pi;
  y = tan(sin(x)) - sin(tan(x));
  plot(x,y,'--rs','LineWidth',2,...
                  'MarkerEdgeColor','k',...
                  'MarkerFaceColor','g',...
                  'MarkerSize',10)
  

produce a graph with:

• A red dashed line with square markers
• A line width of two points
• The edge of the marker colored black
• The face of the marker colored green
• The size of the marker set to 10 points
