+
 = what are all available shortcode attributes? =
+
 The attributes are:
+
 1. gpx: relative path to gpx
+
 1. width: width in pixels
+
 1. mheight: map height
+
 1. gheight: graph height
+
 1. mtype: map aviable types are: HYBRID, ROADMAP, SATELLITE, TERRAIN
+
 shortcode with all the attributes : [sgpx gpx="&gt;relative path to your gpx&lt;" width=100% mheight=300px gheight=200px mtype=SATELLITE]
 
 = What happening if I've a very large gpx? =
 This plugin will print a small amout of points to to speedup javascript and pageload.
