Does anyone know how to increase the linewidth of a MeshLinePlot in Kivy?
Thank you
I got the answer from @Ikolim to work modifying the LinePLot function from kivy.graph
class LinePlot(Plot):
'''LinePlot draws using a standard Line object.
'''
'''Args:
line_width (float) - the width of the graph line
'''
def __init__(self, line_width=1, **kwargs):
self._line_width = line_width # instead of kwargs.get('line_width', 1)
super(LinePlot, self).__init__(**kwargs)
Base on the method __init__ for Kivy garden.graph at https://github.com/kivy-garden/garden.graph/blob/master/init.py, MeshLinePlot currently does not support line width. But LinePlot do support line width.
self.plot = LinePlot(line_width=4, color=[1, 0, 0, 1])
