Graph with KivyMD won't render labels

[Tyrn]

Run on MDApp, a Graph example gets shorn of labels and other peripheral decorations.

Run the following example with and without a command line argument:

$ python graphlayout.py [anything]

I can't tell where the wrinkle belongs, yet I hope there's something to be done about it.

graphlayout.py:

import sys
from math import sin
from kivy.lang import Builder
from kivy.properties import ObjectProperty
if len(sys.argv) > 1:
    from kivy.app import App
else:
    from kivymd.app import MDApp as App
from kivy.uix.widget import Widget
from kivy_garden.graph import Graph, MeshLinePlot

class SetGraph(Widget):
    def update_graph(self):
        plot = MeshLinePlot(color=[1, 0, 0, 1])
        plot.points = [(x, sin(x / 10.0)) for x in range(0, 101)]
        App.get_running_app().root.ids.graph_test.add_plot(plot)

class GraphLayoutApp(App):
    def build(self):
        return Builder.load_file("graphlayout.kv")

    def on_start(self):
        """On Start"""
        ids = self.root.ids
        ids.g_test.update_graph()

if __name__ == "__main__":
    GraphLayoutApp().run()

graphlayout.kv:

#:import MeshLinePlot kivy_garden.graph.MeshLinePlot
BoxLayout:
    orientation: "vertical"
    SetGraph:
        id: g_test
        Graph:
            id: graph_test
            plot: MeshLinePlot
            xlabel:'X'
            ylabel:'Y'
            x_ticks_minor:5
            x_tics_major:25
            y_ticks_major:1
            y_grid_label:True
            x_grid_label:True
            padding:5
            x_grid:True
            y_grid:True
            xmin:-0
            xmax:100
            ymin:-1
            ymax:1
            pos: 0, root.height / 6
            size: root.width * 2 / 4 , root.height * 18 / 24

@Tyrn I found a fix. You just need to add a color for labels:

Graph:
    label_options: {"color": [.5, .5, .5, 1], "bold": True}
