title: How to change marker border width and hatch width?
body: <p>In this example of a marker from my scatter plot I have set the color to green, and edge color to black, and hatch to "|".  For the hatch pattern to show up at all I must set the edgecolor, however when I do, I get a very thick border around the marker.  Two questions:</p>
  
  <p>1) How can I to set the size of this border (preferably to 0)?</p>
  
  <p>2) How can I increase the thickness of the hatch lines?</p>
