1. 放置一个QGraph View

2. 提升成ImageView

ImageView

pyqtgraph.h

3. 生成Ui_XXX文件

4.添加一下代码

生成一个新的py文件

from GUI.NakedSomaToolMainWindow import *
from PyQt5.QtWidgets import *

from PyQt5.QtCore import *


class MainWindow(QMainWindow, Ui_MainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()#调用父类的构造函数
        self.setupUi(self)

if __name__ == "__main__":
    import sys
    app = QApplication(sys.argv)
    ui = MainWindow()

    import numpy as np
    from pyqtgraph.Qt import QtCore, QtGui
    import pyqtgraph as pg

    img = pg.gaussianFilter(np.random.normal(size=(200, 200)), (5, 5)) * 20 + 100
    img = img[np.newaxis, :, :]
    decay = np.exp(-np.linspace(0, 0.3, 100))[:, np.newaxis, np.newaxis]
    data = np.random.normal(size=(100, 200, 200))
    data += img * decay
    data += 2

    ## Add time-varying signal
    sig = np.zeros(data.shape[0])
    sig[30:] += np.exp(-np.linspace(1, 10, 70))
    sig[40:] += np.exp(-np.linspace(1, 10, 60))
    sig[70:] += np.exp(-np.linspace(1, 10, 30))

    sig = sig[:, np.newaxis, np.newaxis] * 3
    data[:, 50:60, 30:40] += sig

    ui.graphicsView.setImage(data, xvals=np.linspace(1.,3.,data.shape[0]))

    ui.show()
    sys.exit(app.exec_())

效果如下
