Increase the linewidth of a MeshLinePlot in Kivy? - kivy

Question

Does anyone know how to increase the linewidth of a MeshLinePlot in Kivy?
Thank you
Update
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.
snippet
self.plot = LinePlot(line_width=4, color=[1, 0, 0, 1])
Example
main.py
import kivy
kivy.require("1.10.0")
from kivy.app import App
from kivy.lang import Builder
from kivy.uix.boxlayout import BoxLayout
from kivy.garden.graph import Graph, MeshLinePlot, MeshStemPlot, LinePlot, SmoothLinePlot, ContourPlot
import matplotlib.pyplot as plt
from kivy.garden.matplotlib.backend_kivyagg import FigureCanvas
from kivy.utils import get_color_from_hex as rgb
from numpy import sin
kv = """
<GraphCustom>:
<Test>:
orientation: 'vertical'
GraphCustom:
size: self.parent.size
pos: self.parent.pos
"""
Builder.load_string(kv)
class GraphCustom(Graph):
def __init__(self, **kwargs):
super(GraphCustom, self).__init__(**kwargs)
self.label_options = {'color': rgb('#FF0000'), 'bold': True}
self.background_color = rgb('f8f8f2')
self.tick_color = rgb('808080')
self.border_color = rgb('808080')
self.xlabel = 'X'
self.ylabel = 'Y'
self.x_ticks_minor = 5
self.x_ticks_major = 25
self.y_ticks_major = 1
self.y_grid_label = True
self.x_grid_label = True
self.padding = 5
self.x_grid = True
self.y_grid = True
self.xmin = -0
self.xmax = 100
self.ymin = -1
self.ymax = 1
self.stop = False
self.plot = LinePlot(line_width=4, color=[1, 0, 0, 1])
self.plot.points = [(x, sin(x / 10.)) for x in range(0, 101)]
self.add_plot(self.plot)
class Test(BoxLayout):
def __init__(self, *args, **kwargs):
super(Test, self).__init__(*args, **kwargs)
fig1 = plt.figure()
ax1 = fig1.add_subplot(111)
wid = FigureCanvas(fig1)
self.add_widget(wid)
class TestApp(App):
title = "Kivy Garden Graph - LinePlot Demo"
def build(self):
return Test()
if __name__ == '__main__':
TestApp().run()
Output
