怎么在pyqt5 上刷新 折线图
如题有新的数据进来然后 刷新图形
from PyQt5.QtWidgets import *
from test import Ui_UiView

matplotlib.use("Qt5Agg")# 声明使用QT5
from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.figure import Figure

from PyQt5 import sip
from threading import Timer
class MyFigure(FigureCanvas):
def __init__(self, width=5, height=4, dpi=100):
# 创建一个Figure
self.fig = Figure(figsize=(width, height), dpi=dpi)
# 在父类中激活Figure窗口
super(MyFigure, self).__init__(self.fig)
# 创建一个子图， 用于绘制图形用，111表示子图编号，如matlab的subplot(1,1,1)
self.axes = self.fig.add_subplot(111)
class OpenView(QMainWindow, Ui_UiView):
def __init__(self, time_code):
self.time_code = time_code
super(OpenView, self).__init__()
self.setupUi(self)
self.setWindowTitle('分时图数据')
self.setMinimumSize(0, 0)
self.gridlayout = QGridLayout(self.groupBox)# 继承容器groupBox
self.show_df()
def show_df(self):
self.time_code = str(self.time_code) + '.csv' # 获取文件名
time_path = self.time_code.split('_')
self.path = f'..\\data\\tick\\{time_path}\\{self.time_code}'
print(self.path)
self.all_tick = pd.read_csv(self.path)
self.x = np.arange(0, self.all_tick.index[-1]+1)
self.F = MyFigure(width=5, height=4, dpi=100)
self.F.axes.plot(self.x, self.all_tick.close, self.x, self.all_tick.minu)
self.F.axes.set_title("sincos")
self.gridlayout.addWidget(self.F, 0, 1)
def foo(self):
time.sleep(2)
if self.gridlayout.count() > 0:
self.gridlayout.removeWidget(self.F)
self.F.deleteLater()
#
# time.sleep(2)
# self.F.axes.plot(self.x, self.all_tick.close, self.x, self.all_tick.minu)
# # self.gridlayout.addWidget(self.F, 0, 1)
# self.show()# 显示图片
# time.sleep(0.5)
if __name__ == '__main__':
app = QApplication(sys.argv)
time_code = '20210111_000661'
start = OpenView(time_code)
start.show()
t = Timer(5, start.foo)
t.start()
sys.exit(app.exec_())
有大佬能改吗 万分感谢 {:10_277:} while 接收
