+
+\func{void}{SetAxisOrientation}{\param{bool}{ xLeftRight},
+ \param{bool}{ yBottomUp}}
+
+Sets the x and y axis orientation (i.e., the direction from lowest to
+highest values on the axis). The default orientation is the natural
+orientation, e.g. x axis from left to right and y axis from bottom up.
+
+\wxheading{Parameters}
+
+\docparam{xLeftRight}{True to set the x axis orientation to the natural
+left to right orientation, false to invert it.}
+
+\docparam{yBottomUp}{True to set the y axis orientation to the natural
+bottom up orientation, false to invert it.}
