Graph blinks and duplicate on initializing #21

Open mirajTariq opened 5 years ago

mirajTariq commented 5 years ago

BUG DESCRIPTION I am working on simple kivy project to display graphs but as I initialized the graph with some data points and run the app, I get two graphs one originally configured graph and the second mini graph just below the original one and as I maximize the screen size, the mini graph start to blink

To Reproduce Here is the code for simple graph application in kivy. ` from kivy.app import App from kivy.uix.label import Label from kivy.uix.floatlayout import FloatLayout from kivy_garden.graph import Graph, MeshLinePlot

class MyApp(App):

def build(self):
    root = FloatLayout()
    graph = Graph(
        xlabel='TIME',
        ylabel='POWER',
        # x_ticks_minor=5,
        # x_ticks_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=19,
        ymin=0,
        ymax=11,
        size_hint=(0.8, 0.75),
        pos_hint={'x': 0, 'y': 0.15},
    )

    plot = MeshLinePlot(mode='line_strip', color=[0.9, 0.6, 0.3, 1])
    plot.points = [
        (0, 10),
        (1, 9.5),
        (2, 9.8),
        (3, 9.3),
        (4, 9.9),
        (5, 9.8),
        (6, 9.4),
        (7, 9.2),
        (8, 9.2),
        (9, 9.5),
        (10, 9.6),
        (11, 9.1),
        (12, 9.7),
        (13, 9.5),
        (14, 9.5),
        (15, 9.4),
        (16, 9.9),
        (17, 10),
        (18, 9.6),
    ]
    graph.add_plot(plot)
    root.add_widget(graph)
    return root

if name == 'main': MyApp().run()`
