python-3.x - 如何在我的 main.py 和 kv 文件中添加条形图？

问题描述

我想添加一个仅显示在进度屏幕上的条形图。我是 Kivy 和 Python 的新手。我正在使用 matplotlib 作为条形图。我想将 Bar.py 代码集成到我的 main.py 代码和 progress.kv 文件中。我被困在如何将它添加到我的 Progress.kv 文件中。

巴.py

这是我要显示的条形图的代码。

import matplotlib.pyplot as plt 

x = [2,4,6,8,10]
y = [6,7,8,2,4]

x2 = [1,3,5,7,9]
y2 = [7,8,2,4,2]

plt.bar(x,y, label='Bars1', color='blue')
plt.bar(x2,y2, label='Bars2', color='c') 

plt.xlabel('x')
plt.ylabel('y')
plt.title('Interesting Graph\nCheck It out')
plt.legend()
plt.show()

主文件

我想将条形图代码添加到“进度屏幕”而不是通过。

    Config.set('graphics', 'fullscreen', '0')
    Config.set('graphics', 'width', '800')

    ScreenApp().run()

进度.kv

我在 kv 文件中有进度屏幕的所有代码。我想在这里添加设计和细节，但如果没有，那么在 main.py 中。

import matplotlib.pyplot as plt

<Progress>:
canvas.before:
    Color:
        rgb: 1, 1, 1 
    Rectangle:
        pos: self.pos
        size: self.size
Button:
    text:'Patient Menu'
    font_size: 20
    bold: True
    size_hint: None, None
    size: 300, 50
    pos_hint: {'center_x': .5, 'center_y': .1 }   
    color: 1, 1, 1, 1               
    on_press: root.manager.current = 'Patient'

解决方案

条形图的 Progress.kv 文件

#:import MeshLinePlot kivy.garden.graph.MeshLinePlot
#:import get_color_from_hex kivy.utils
<Progress>:
    BoxLayout:
        orientation: 'vertical'
        padding: [10,20,10,20]
        spacing: 20
    Graph:
            height:1000
            width:1000
            id: graph_test
            xlabel:'Algorithms'
            ylabel:'Accuracy'
            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:3
            ymin:0
            ymax:100
            pos: 0, root.height
            size: root.width, root.height

进度的 Python 代码

import itertools

from kivy.app import App

from kivy.utils import get_color_from_hex as rgb

from kivy.uix.screenmanager import Screen, SlideTransition

from kivy.properties import StringProperty,ObjectProperty

from math import sin

from kivy.garden.graph import Graph, MeshLinePlot, BarPlot

colors = itertools.cycle([rgb('7dac9f'), rgb('dc7062'), rgb('66a8d4'), rgb('e5b060')])

class Progress(Screen):

    def assign(self):

        super(Progress,self).__init__()

        self.sensorEnabled = True
        self.graph= self.ids.graph_test

        self.plot = []
        self.plot.append(BarPlot(color=next(colors),bar_spacing=.72))  #x - Red
        self.plot.append(BarPlot(color=next(colors),bar_spacing=.72))  # Y - Green
        self.plot.append(BarPlot(color=next(colors),bar_spacing=.72))  # Z - Blue

        self.reset_plots(self.graph)

        for plot in self.plot:
            self.graph.add_plot(plot)

    def reset_plots(self,graph):
        for plot in self.plot:
            plot.bind_to_graph(graph)
            plot.points = []

        self.counter = 1
