wx.lib.plot.polyobjects.PolyLine

Creates PolyLine object

param points

The points that make up the line

type points

list of [x, y] values

param **attr

keyword attributes

Keyword and Default	Description	Type
colour='black'	Line color	wx.Colour
width=1	Line width	float
style=wx.PENSTYLE_SOLID	Line style	wx.PenStyle
legend=''	Legend string	str
drawstyle='line'	see below	str

Draw style	Description
'line'	Draws an straight line between consecutive points
'steps-pre'	Draws a line down from point A and then right to point B
'steps-post'	Draws a line right from point A and then down to point B
'steps-mid-x'	Draws a line horizontally to half way between A and B, then draws a line vertically, then again horizontally to point B.
'steps-mid-y'	Draws a line vertically to half way between A and B, then draws a line horizonatally, then again vertically to point B. Note: This typically does not look very good
