Line widths < 1 px will be rounded up to 1 px when using the 'gl' method. connect : str or array Determines which vertices are connected by lines. * "strip" causes the line to be drawn with each vertex connected to the next. * "segments" causes each pair of vertices to draw an independent line segment * int numpy arrays specify the exact set of segment pairs to connect. * bool numpy arrays specify which _adjacent_ pairs to connect.
