Question

我创建了一个GUI，我在其中读取CSV文件并计算数据的液体输出。现在我想做两件事：
1）我想基于时间生成输出，就像日期
一样 2）我想在GUI中的单独窗口上生成用户特定时间或日期的图表

这是我的代码：

import csv
from tkinter import *
from tkinter.filedialog import askopenfilename
from tkinter.messagebox import showwarning, showinfo
import datetime

#csv_file = csv.reader(open("C:\Users\Lala Rushan\Downloads\ARIF Drop Monitoring Final\ARIF Drop Monitoring Final\DataLog.csv"))
from Tools.scripts.treesync import raw_input
class App(Frame):
    def __init__(self, master):
        Frame.__init__(self, master)


        button1 = Button(self, text="Browse for a file", command=self.askfilename)
        button2 = Button(self, text="Count the file", command=self.takedate)
        button3 = Button(self, text="Exit", command=master.destroy)
        button1.grid()
        button2.grid()
        button3.grid()
        self.userInputFromRaw = Entry(self)
        self.userInputFromRaw.grid()

        self.userInputToRaw = Entry(self)
        self.userInputToRaw.grid()

        self.grid()

    def askfilename(self):
        in_file = askopenfilename()
        if not in_file.endswith(('.CSV')):
            showwarning('Are you trying to annoy me?', 'How about giving me a CSV file, genius?')
        else:
            self.in_file=in_file

    def CsvImport(self,csv_file):


        dist = 0
        for row in csv_file:
            _dist = row[0]
            try:
                _dist = float(_dist)
            except ValueError:
                _dist = 0

            dist += _dist
        print ("Urine Volume is: %.2f" % (_dist*0.05))


    def takedate(self):
        from_raw = self.userInputFromRaw.get()
        from_date = datetime.date(*map(int, from_raw.split('/')))
        print ('From date: = ' + str(from_date))
        to_raw = self.userInputToRaw.get()
        to_date = datetime.date(*map(int, to_raw.split('/')))
        in_file = ("H:\DataLog.csv")
        in_file= csv.reader(open(in_file,"r"))

        for line in in_file:
            _dist = line[0]
            try:
                file_date =  datetime.date(*map(int, line[1].split(' ')[1].split('/')))
                if from_date <= file_date <= to_date:
                    self.CsvImport(in_file)

            except IndexError:
                pass

root = Tk()
root.title("Urine Measurement")
root.geometry("500x500")
app = App(root)
root.mainloop()

如何完成上述2项任务？

Answer 1

我必须同意Jacques de Hooge，你应该使用500。在文件的初始化时，导入它：

matplotlib

由于您只想用绘图打开一个新窗口，import matplotlib.pyplot as plt窗口就足够了。您可以使用散点图：

matplotlib

其中plt.scatter(X, Y)是具有x坐标的可迭代，X是具有y坐标的可迭代。由于您希望通过不断变化的时间做某事，您可以在Y列表中显示要绘制的值，执行以下操作：

values

您可能还想在一个线程中运行它，以便在plt.scatter(range(len(values)), values) plt.show()窗口打开时程序的其余部分不会“冻结”。有很多地方可以解释这一点。
